Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Linux kernels use today are mostly 2.6.33 or later.

If you like to use tiny linux operating system and build a wifi internet laptop, you need a list of drivers already in kernels.

List of compatible wifi drivers:
Prism HostAP(IEEE 802.11b)
Atheros MadWiFi
Prism54 54G
Ralink rt2400
Ralink rt2500
Broadcom b43(4312)
Realtek RTL8180
TI ACS100/ACX111
Intel ipwx9x5(Centrino)

These can be pcmcia, USB or mini pci(e) cards.

When you buy used wifi cards, look at the drivers already in kernel 2.6.33 or later, B43 is the most popular, Atheros can use B43 firmware, others depend on many models that could be compatible.

This helps you to select peripherals that are hardware compatible with Linux kernels.

In WiFi traffic is heavy, and /b may happen to be faster than /g WiFi due to unnecessary to shift data rates and unnecessary to sync clocks that cause packet lossy.

Stripped down Linux is less buggy without desktop apps. Browsers are now autoupdated to free your efforts to update yourself.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Understanding wifi drivers in kernels are auto detected, after boot process started.

You will find wlan0 is detected and brand of wifi notified. Then drivers installed in wifi manager.

But you need a wifi utility to radio on, config, scan and connect to a list of access points(hotspots).

Once connected, you can launch browser to surf the net.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

The speed of wiFi is according to 802.11 specs. /a/b/g/n are increasing levels of speed of data rates.

Data is transmitted in data channels of upto 14 channels. Then data is send and received from 1 mbps to 480 mbps.

Unfortunately, data rates are also data channels, the real speed when you download from internet is really only 1/2 mbps or 100/200 kBps. So, /b wifi data transmission may be as fast or faster than /g or /n wifi. This allows more users in the same gateway router.

Is 55 kBps fast.enough for xml streaming? Yes.

But in mpeg4/h.264 zoom can do reduced pixel transfer then zoom back to higher resolution off line.

This can improve wifi traffic control.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Many wifi pcmcia cards are 5v and 16bits, which works with all the laptops. Whereas, most cardbus pcmcia wifi can not work with older laptops. These are all /b, and easy to install.

Most new laptops have mini pci cards for wifi, they are detected and installed without fuss. Some newer laptops have pci(e) which is faster bus, but still limited to 100/200 kBps wifi data transfer.

USB 1.1/1.0 are on many 10 year old laptops. You can do better with USB 2.0 adapter on the pcmcia slot. Watch out for 5v current limitation on pcmcia bus. Use 5v external power supply at all times. USB wifi has problems of short antenna and chipset might overheat and slow down to 900 bytes per second(Ralink2870). Use Realteck chipset 8180 preferred. Realtek wifi needs reset by radio off then on to get it working better. Windows can adjust signal strength on gateway routers, Linux did not have autoupdate.

Good luck on Linux tiny operating system, WiFi will make it more pleasant. Linux browsers have not yet WiFi traffic control of double click to start wifi radio on and logon to gateway router's ip address in memory then complete the chechsum of download bit torrent from upto ten servers simultaneously(by download manager software included in browser to prevent lossy packets from occuring).

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Which pcmcia wifi cards to avoid? Prism 2/2.5/3 or IEEE802.11b or orinoco gold or silver. Avoid 802.11/a.

The drivers and firmware were developed very long ago. It is difficult to auto detect and install flash firmware. Your wifi card may be made corrupted and totally useless. On Windows, if you have the cd with original driver, windows can install it and flawlessly.

You are better off using atheros wifi pcmcia cards(DLink DWA642).  Ath9k drivers are auto detected and b43 firmware is installed(38 files). Works with SliTaz 3.0 stable in netbox wifi manager and auto detect wlan0 and install b43 firmware.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Hostap is too old a driver, should be substituted with orinoco_cs drivers for many pcmcia wifi cards

Madwifi drivers should be substituted with ath9k.

B43 drivers need b43 firmware to make sure you get the latest feature of /g/n or /m. Firmware can change wifi features and speed, on top of hardware features.

Linux wifi drivers and wifi manager software is getting better, but we are adding wifi traffic control in browser to allow more users at higher speed transmission. Some work will be done offline just upload multitasking at the same time.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

The secret of firmware in wifi?

WiFi started with Lucent and its orinoco hermes chipset. Then its followed by Intersil prism 2, 2.5, 3 as well as symbol spectrum. But the speed is limited to /b 11 mbps max.

/g is faster at 54 mbps speed max. Then /n is multitasking with three /g data channels.

So, Broadcom firmware can make /g chipset add firmware and became /n WiFi card. You can also add /g firmware to /b chipset to become /g hardware.

Usually, Linux driver developers like to make universal drivers, but first they must do firmware to make all the chipsets have the same functions and same instructions for drivers.

But when we work on wifi traffic control, we realized that data rate is more parallel data channels to speed up data transfer, and download manager(10 servers download at the same time) is key to data integrity. And radio off when not using wifi, can have more users on each gateway router..

So, the die is cast. If each data channel can do 20 mbps; 480 mbps needs 24 data channels all transferring data simultaneously.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

If kernel has all the wifi drivers, then it can be installed by dhcpcd; then net manager or wifi manager is not needed. But dhcpcd can not handlle the autodetect of drivers with many chipsets lumped together in one driver. So, you need to load the firmware(/g to /n) and drivers  manually and test the connection to gateway router. Normally, if you see a list of hotspots encrypted or unsecured, your wifi card is working and you can connect to any of the hotspots.

So, your wifi manager in the network manager has to wait after dhcpcd failed to autodetect, then it takes over and you can experiment to load different drivers that had no firmware, or install firmware for the chipset, then load the drivers to connect. Understanding of the sequence of operation of connecting router is important for distro maintainers.

Austrumi v2.3.0 works(N43 drivers and firmware for broadcom4318 mini pci), if you do dhcp to get the ip address from the router, then select the list of hotspot to connect. Puppy 528 lucid only works(TI acx100) if autodetected. dougal's and barry's network managers are not programmed right! SliTaz can autodetect ath9k(Dlink DWA642) but not orinoco_cs which has to be manually loaded and hotspot selected to connect.

We have a lot of work to get Linux distros to automate wifi connections in library and MacDonalds. Great speeds for download of mBs of software. Not bad for YouTube downloads either.

Footnote:
To automate wifi drivers install, a hotspot list has to be automatically connected. It takes time to do dhcpcd to the hotspot list. If dhcpcd failed then wifi manager should be immediately available to manually install wifi drivers on firmware and make the wifi connection. All the small distros with tiny Linux kernels had to rewrite scripts for wifi manager..

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

We hear many reports that wifi units work once and then failed on reboot.

It is now traced to drivers or firmware loaded then forgot to unload before using anothr driver or firmware. some wifi has circuits with flash memory that can be upgraded. If any codes upgraded the firmwre inside the wifi circuit, then the wifi is damaged forever. I have to throw away a few intersil prism wifi pc-cards.

It is a severe warning against Linux kernels, when autodetect to lock out drivers and firmware to prevent contaminating wifi flash memory inside the wifi circuit in use.

Linux being open source, and hacked by hobbyists of less skills, did not understand the circuits used by wifi units. And I found that some Prism wifi circuits can load orinoco_cs(prismI) and add ath9k to work with Prism2,2.5,3 circuits[silver orinoco or cabletron DS high rate(24DS4) roamabout].

Linux wifi drivers need more explanations and warnings. http://linuxwireless.org/en/users/Drivers

Safer to use ndiswrapper? Microsoft wifi drivers may not work in Linux if for Win95/98. Win2k or XP drivers may. Vista and Win7 wifi drivers may not. Some distinction of single and multi core drivers in respective operating systems.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

WiFi drivers are separated from utility(wireless manager) that configs the chipset with a number of controls, such as radio on/off, disable the unit, Microsoft zero config, and tray icon shown. Then the dashboard status info displays. these info are important part of wifi operation. Total number of wifi hotspots, encryption standards, and signal strength.

Without these software, your wifi will not work well. Some wifi maybe lacking in some of the utility and its dashboard features.

But more importantly, the wifi chipset may change data rates on you depending on the number of users on the gateway router.. The final download speed is still 200 kBps maximum. DSSS is 1, 2, 5.5, 11 mbps. OFDM is 6, 9, 12, 18, 24, 36, 48, 54 mbps.

So, we are now designing wifi traffic control in browsers, And the data rate becomes data channels on the air. You can have twelve users with 12 separated data channels if the router can handle the cache. That really mans each wifi chipset has 12 cores.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

SliTaz and Dlink dwa642 chipset use ath9k plus b43 firmware to connect. But will lose connection with wifi not responding. Have to reconnect after refresh hotspot list in wifi manager config. WiFi manager should always be on the desktop to do connection again if lost connection at anytime.

Wifi manager never show disconnection at any time. Just midori browser crashes.  This is the way tiny Linux operates, wifi manager doen't refresh connection status, not too much explanation of what happened. You learn to compensate for the glitches.

Maybe Midori should have a reconnect wifi button? Or have automated reconnect action when browser crashed.

Footnote:
With wifi manager, network on, stop connection, then double click on hotspot will reconnect in a jiffy, the wifi card led will flash when disconnected, then Midori browser will start to download webpage again.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

It took a while and many different wifi pc-cards to find out the way Linux wifi drivers work. There are no detailed wifi drivers explained since 2004. And many google questions are not generalized to help you use any wifi cards. Since 2004, B43 firmware included /n features.

Basically, there are mini pci or pcie(Intel Centrino /b), USB and pc-cards. mini pci has large antenna, and has an advantage to use free hotspots. There are charts also on data rate and distance of wifi signal strength. The higher the data rates the shorter the distance you can use hotspot. So, 1-2 mbps data rates if fixed can do wonders. Higher data rates can make signals too low for data transfer.

On the contrary, USB wifi keys have just the 3/4" long antenna(1/4 wavelength). It depends on hot temperature chipset to get signal strength sensitivity. Which makes it easily become defective in use. Ralink worse than Realtek.

Then there are so many older wifi pc-cards still usable except perhaps prism2.5 which can have firmware contamination from drivers. They can be a waste of time, throw them away.

The best wifi is Broadcom, then atheros, Marvel 8335(win2k/XP), then realtek. The prism chipsets have too many different circuits. We have discovered how some of the drivers and firmware work together.. The reason is DSSS and OFDM are add-ons, and /n is multiple OFDM.

This general summary gets the feeling of how to use Linux wifi drivers. Many distros have net manager bugs that had to be sorted out from kernel mode auto detect. Drivers that are not used in a complementary way does not work. ie, Orinoco silver(24DS4) pc-card needs 5v 16bit pcmcia drivers(orinoco_cs), then add ath9k wifi drivers with b43 firmware installed to work. There are a lot of these on the market(ebay) that will work in SliTaz wifi manager.

Austrumi 2.4.0 needs to find some wifi cards that will work with their wifi auto detected in kernel mode(2.6.39.3). The only one that has a possibility is the broadcom mini pci chipset. using brcmsmac drivers blacklisting brcm80211 b43 drivers.Older ath9k with b43 firmware may still be a choice in wifi cardbus(3.3v  32 bit) pc-cards. Austrumi 2.3.0 however will install b43 drivers for 4318 chipset on mini pci bus and net manager works after dhcp on wlan0. There are reports of 2.6.39.2 problems with /n wifi but not /g wifi data transmission; whereas 2.6.38 had no problems.

Puppy wifi pc-card installed wisecom TI acx-100 drivers from kernel used in LUPU 528. All other cards are not usable because of dougals drivers did not have firmware installed. Puppy gives no regards to drivers used for pci or USB or pcmcia bus.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Since Linux included wifi drivers in the kernels, the drivers got bugs galore when Linus merged them into new kernel versions.

Kernel bugs did not have maintainers that try out all the drivers included, which must also include firmware for wifi specifications. Many older wifi /g can add firmware to simulated /n wifi features. Drivers must allow more cache to handle multiple data channels.

Anyway, we are now looking at Microsoft software wifi downloads at 540 kBps. Which is no where near 480mbps ARRS download speed(24 data channels download at the same time at 20 mbps per channel). Kernel 2.6.39.3 did not allow more cache for /n operation, and wifi can only handle /g. kernel 2.6.38 can handle multi xhannels of /n operation of wifi cards.

So, now we know how to fix kernel 2.6.39.3? SliTaz using 2.6.30 is still on DSSS not even on OFDM let alone multi data channels simultaneously /n operation. Download manager software is only 10 data channels, have to upgrade to 24 data channels for ARRS.

Strange footnote:
Some prism2.5 wifi card from Taiwan had problems with memory. site survey only will show one hotspot. After using it for several hours, it then showed 3 hotspots and connected to one. Older wifi cards may have to be used for a while to cure capacitors or dry out condensation? signal sensitivity(condensation Problem) also improved later.. Drivers can install by auto detect on W2k. Slitaz destroyed 4 of them, and one got destroyed by Intersil IEEE802.11 driver firmware install. We have 16 hotspots, so far only 4 is shown, will have to leave it on for sometime yet to get more sensitive to signals and list all the hotspots.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

As we look into Wifi drivers; we only find a few WiFi devices that can work with a few drivers. Generally, b43 and ath9k all have problems, and you are lucky to find a few models of each brand that can use the drivers available.

This is the reason that you have to report the models that worked in each kernel version number and drivers.

Operating system compatibility with hardware is a very serious problem still with Linux kernels.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

The driver b43 in sliTaz maybe for pci bus only. For linksys broadcom chipset pc-card maybe you have to config pcmcia.

The Linksys WPC54GV1.2 BCM4306 chipset is power on by yenta drivers in the pcmcia slot, but b43 drivers and firmware does not goto pcmcia bus? google shows that config is needed to get on the pcmcia bus for the drivers to work, to get radio signals to show network hotspots.

Anyway, had to go back to orinoco_cs to get back on the internet. This driver is good for most of the gold, silver and maybe even bronze lucent wifi pc-cards, but running /b mode.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

More information on wireless lan cards in one list.

http://linux-wless.passys.nl/query_alles.php

This is a fairly complete listing of wifi cards manufactured over the years. It is how ever not really complete, ie. Linksys wpc11 can use orinoco_cs drivers. WPC54G-2 marked WPC54GV1 is really WPC54GV2 with TI chipset.
There are many others the drivers over the years had been rewritten and no longer worked especially linux drivers(open source by any hacker not properly maintained). The assumption of linux distros had the correct platform(i386, i686) that can use the drivers is often questionable. But, Dlink DWA-642 works with ath9k is confirmed.

However, orinoco_cs drivers still works for Linux i386 distros. See list of wifi cards that is supported by orinoco drivers in i386 linux operating systems.

http://pcmcia-cs.sourceforge.net/ftp/SUPPORTED.CARDS

This list included many cards and drivers. Due to the vintage of this list. works for i386 distros.

Read the list of orinoco_cs cards supported, many cards have different chipsets, but drivers are the same.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

There are some wifi 802.11b USB unit made in the past that was very nice, except difficult to find the correct drivers and utility setup software. It is the Compex(atmel chipset) Wlu11a model 2 with a long mini USB cable. The driver software is for model 2 and 3. Wlu11a-20040723.zip 6.2 mB for windows from 98 to XP. You install the setup by actuin checkout in Winzip9.0. This unit is great for desktops which maybe stationary and need to move the antenna in place for quality and signal strength. Red Hat linux uses the drivers for ndiswrapper.

The DSSS mode and 11 mbps speed can be used for very fast software download(550 kBps).

There are other such USB wifi standalone units all using atmel chipsets. Speedstream ss1022 and dlink DWL-120 as well. Some may have hardware problems of moisture and condensation overloading USB 5 volt supply. You have to try them out for a few days to stablise them.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

WiFi drivers are in two parts, the utility to manage the connection to a network and drivers for an operating system. Some times just getting the drivers are not sufficient to run the wifi connection.

In windows, if you find a driver with a setup exe file, it will install the utility as well as the drivers. They do not have to use add hardware in the control panel. If you use add hardware in control panel you have to use WinXP which has its own utility for WiFi connection. If the drivers include setup, it usually can work  in all the windows from 98 to XP. Those wifi whether pcmcia or USB can be very useful if you have many computers.

In linux too, kernels 2.6 now includes wifi drivers. But many don't work anymore. If you are lucky, the wifi manufacturer provide a linux driver that can be setup and run by its own utility.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

The list of wifi pc-cards that can use the orinoco_cs drivers are quite long. They are mostly older 5v 16 bit cards, very cheap if you want to invest in them because they can run 550 kBps transmission. Much faster than 65 kBps that /G and /N wifi cards can do.

But which ones are better quality or more abundant?

SMC 2632W V2, only one that can not connect using orinoco_cs
Netgear MA401RA
Linksys wpc11
Linksys wpc11 V3

Here are the tests on Slitaz 3.0 stable. Good and fast except SMC.

Trouble shooting footnote:
Since these pcmcia cards are quite old and not being used for some time. It may have moisture problem, needs power on for some time to warm up circuits. Once LED lights work, often connect function needs o be turned on many times or radio hotspot scan done many times as well. The more you use it, the better it will perform.

The orinoco_cs drivers is a universal drivers for many orinoco cipsets. Its an advantage of Linux drivers same as vga/791 drivers. You have to take advantage while you can to use all the cheap wifi pc-cards if available.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Lucent had made orinoco wifi client silver units a standard for comparison with other manufacturers. One of the USB-w design is just that. Inside the case, Lucent had a pc-card wifi card plugged into a USB1.1 socket. So, the 7.82 driver for pcmcia card works with the USB unit as well. USB 1.1 is 12 mbps maximum, and works quite well with 11 mbps wifi DSSS mode. Lucent claims transfer rate of 700 kBps, and may have 900 kBps potential if the server is fast.

It connects after boot. has power and link transmission LED lights. But in use, Firefox is not finding servers and page not loading correctly. Which means the units is not working even when the utility says its connected.

Once, the wifi drivers are autoupdated with wifi traffic control, it then works again.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

There are also pcmcia cellphone cards, 3G or cdma. They are actually USB and the modems are ttyso drivers, or usbacm0 drivers. the modem card needs a sim card too, to connect to telephone central office by a dialer. In general same as any external modem, except it runs on cellphone frequencies.

Its expensive by the minute or contract monthly fees and not like free hotspot Wifi available at many places. We are not suggesting you use it for internet often.

There are pc-cards that had many protocol and 802.11b is among the cellphone functions.:
Nokia D311
Sony Ericsson GC79

Both are very expensive new. But mine did not find wireless devices but will do modem with a sim card, using windows drivers. So, have to find some good ones to try the 802.11b connections(notice that led lights for power or link did not work). Was hoping orinoco drivers of linux can work them, but not known yet.

these expensive wireless cards with 3G slow connection is for convenience with your sim cars inserted. I did not know that WuFu option also need sim card inserted. Then you select infrastructure to do free wifi connect/

This confirms the 900 kBps speed of DSSS mode on the lucent USB-W wifi

It almost equal to broadband 1 mBps wired connections for internet downloads.

And wireless is always more convenient than wired connections.

Re: Linux kernels and wireless wifi drivers ? List of wifi pc-cards to use

Now that we found out some of the characteristics of DSSS mode data transfer. We are looking for manufacturer's utility that moght set the data rate. You would love to run every download at 11 mbps for 900 kBps. But traffic might be heavier than you think and you have to drop down to 1 mbps for 65 kBps speed.

But certainly, that you might set the data rate to avoid use of OFDM mode, where RX resend is too high a ratio that you are wasting everybodies' time, not just your own download time.

Are there other options that might help you? Take a look at the managed RX packet numbers on the same data channel? This number is the encrypted RX packets that you are receiving but not used. You are sharing the time and space continuum. It certainly limits your maximum download speed.

It is important to know the threshold of fragmentation of packets and RX/TX threshold(about 2500 bytes. if too many fragmentations, then you may lose the download data unable to track checksum subtotals.

Some wifi suppliers such as Lucent had wifi circuit testing facility in their utility, which is very handy to get an extra level of confidence in their equipment.

But as in all cases, the speed of download is only shown in your download manager which keeps data integrity at the utmost importance. Some browser such as Midori also show bargraph on completion of webpage download. But the bargraph is not calibrated to kBps.
