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

This info is now including Lucent USB-W. Another vintage pcmcia wifi card plugged into a USB adaptor. Its 802.11b only. Has a nice utility but not as complex as Compex wufi utility. But it has a test feture to assure everything is working. Drivers is 7.82 for both pc-cards or USB cards.

These standalone wifi units are for desktop, so that a long USB wire can move the antenna to the most sensitive spot(3/4" quarter wave length).

Lucent tested to 900 kBps speed on DSSS 11 mbps setting.

If anything, this forces 266 mhz laptops to run data transfer from internet  faster than ever. Especially on free hotspots FREE. But unfortunately, Wifi WL110 card on compaq 32 mB laptop using W95(IE5.5) is only 35 kBps(5x dialup) top speed. So, working with W2k pro or XP pro has the speed advantage with more drams(320 mB drams) on the laptops.

To speed up wifi on W95 maybe fine tuning on drivers and data rate speed selection, more on this later. We have to use a lucent driver and any orinoco wifi /b card. You start with Agere 7.82 or windows_drivers_sr02-2.3.zip and the list supplied by softpedia of wifi pc-cards that worked with this wifi drivers. Good Luck trying out with W95 or W98/SE.

So, this is how this R&D wifi project saga continues.

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

WiFi cards often depend on utility software to work better. Range and signal strength is not sufficient, Quality of data integrity is checksum of packets related.

But older wifi cards often suffer moisture attacks, and need to power on to dry up , for weeks(2) at a time. Then the wifi card cools down and all functions qork. The first inducation is hotspots site survey show more channels of hotspots. Then the encryption on/off on each data channel. After which, the gateway router can be connected.

This is typical of restoring of usage of old wifi cards. Have fun.

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

History had shown Linux developed upto Pentium III(branch prediction 32 bit i686; kernel i486 and i586 has no branch prediction). Then Intel added drivers for Pentium 4 and the latest core cpus. Keep in mind that you have to add drivers for Pentium III; but since Pentium 4, the intel drivers are in the Linux kernels. You have to defeat kernel mode(video accelerator framebuffer for fast fps) if your cpu is Pentium III. While Linux uses software FPU(to be defeated), Pentium 4 has 32 bit multi FPUs hardware.

Centrino/b wifi was built into the Pentium 4 chipset, and Intel drivers in kernel will install it and connect by associated hotspot. Or associated access point(no encryption for free hotspot) by dhcp to gateway router to get an ip address for connection. Encrypted routers will need utility to add encryption codes for connection on dhcp for ip address assignment.

This is the way Linux kernels are developing by Intel contributed drivers for cpu platforms. If we only restore older computers and earlier atom cpus, we(tiny Slitaz) should strip out the Intel drivers or defeat them to avoid missing bindings for some files(older drivers failed to work) in newer kernels since 2.6.24.x.

In some Intel drivers, video framebuffers overworked cpus. In some Centrino, the DSSS mode for /b Centrino drivers can run WiFi upto 900 kBps whereas the newer Centrino with OFDM mode can only run as fast as 65 kBps due to too many packets being resend. There are other characteristics of core cpus that needed to work simmetrical processing of subdivided apps. Most Linux apps are not suitable for subdivision such as download manager of file. This will take a few years to move from subdivided tasks to busy fell over type of parallel data processing by core cpu being busy and shift loads to free cpu cores.

So, this trend of linux kernel development will slowly improve in the next ten years. In the mean time Linux for ARM platform is still 8 bit in nature, until thumb(branch prediction 16 bit) or thumb2(32 bit) processing can be programmed in Linux kernels and apps.

We have now learned how to use sliTaz 3.0 stable for fast wifi improvement of Pentium III laptops and desktops. which will extend the life of older 1999 computers another ten years in service. Wifi at 550-900 Kbps is fast cloud computing indeed.

Have fun, and use the newer cpus properly too by modifying Intel drivers in Linux kernels. Android is johnny came lately, and will have patent problems with Apple touch system(how your fingers move on touch screen). It also has to try speech commands on computers soon.

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

For w2k, orinoco driver for all the models(list on softpedia download page) is sr02.3.zip or v7.82. You can still download from google search engine. http://drivers.softpedia.com/get/NETWOR … -782.shtml

The drivers will automatically connect you to a unsecured hotspot. But they do have a Orinoco client manager that will get the site survey and list all the hotspots before drivers v 7.82.

You can still find and download the Orinoco clent manager v 6.01. Or the later v2.92. But they do not work with v7.82 drivers which connects without client manager. Roll back to drivers V7.62(sr02.1.zip) can use client manager v 2.92. http://www.wireless-driver.com/proxim-o … #5software

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

The problem of /g/n wifi chipset is the ofdm transmission easily jammed and had to resend packets to slow down wifi traffic. Then there is the problem of overheating on the chipset itself which corrupts data in the packets sent..

I have done scotch tape oven and cooling fins(one layer or more) to get ofdm chipset sort of working consistently, but they are too slow due to resending packets until data is checksumed.

So, we have to use orinoco/b wifi units. The chipset is larger and only DSSS circuits, no overheating problems.

When you get 550 kBps transmission consistently, what a joy. Internet surfing finished in no time at all.

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

Dell c610 uses True mobile 1500 pci card vintage 2006 based on broadcom chipset..

recently tested and will download at 387 kBps to do Firefox 9.01. its one of the few wifi cards that did not overheat. But then 14.5 mB only takes a few seconds to download.

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

We have been avoiding WEP and WPA encryption for the orinoco wifi pc-cards.

The reason is more free hotspots are available. Cable and telco routers are very expensive.

Some settop box routers may offer access point for neighbors free of encryption, if they only use mostly TV.

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

Microsoft had done very good wifi drivers autoupdate. Many WiFi/g/n drivers had temperature sensing software now to run DSSS mode upto 600 kBps. If over heating, the speed will drop back to cool the wifi chip. Some of my marvel 8335 chipset and belkin chipset are all now capable of very high speeds without dropping back to a few Bps.

OFDM mode of faster than 11 mbps still may resend packets too often(upto 6x resend for each received packets). This is due to the original Motorola scheme for AM stereo application, very low frequency stereo response. anything higher frequency gets  jammed.

So far older operating systems(W95/98SE) are very pleasant to surf the net and do downloads of movies, music or software. Older laptops can all be put back into service with orinoco pcmcia wifi cards.

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

WiFi usage is mostly at the airport, where pwoplw had nothing to do. And it may be 2-3% or all the waiting passengers.

The public library wifi users are limited to less than 10 people. So, most ofdm speeds are 24 mbps down from 54 mbps for one user.

MacDonald fast foods do have WiFi; but people don't have time to use WiFi.

Starbuck should have WiFi users, but I have no data. With iPad being so popular, 3G is still the way to communicate. wiFi by suppliers like Clear is still home bound.

To use post office wifi, you need a router that has a password printed underneath the unit. Its encrypted wifi.

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

Linux kernels best for older computers are 2.6.24/2.6.30 which has the orinoco drivers.

Centos and Lucid Ubuntu are using 2.6.32, which has very few bugs. Since 2009, the patches numbered over 3386. Kernel 2.6.32 will be maintained by the same person that maintains 2.4.x from now on.

New 3.x kernels are more troublesome not only for WiFi drivers, but will take a few years to work out the patches for bugs created by i3/i5/i7 cpus and other Intel drivers.

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

WinCE used IE6 in tablets and netbooks. IE6 has data transfer speeds for dialup modems limited to 5.5 kBps maximum.

Using new Firefox, wifi is not limited to 5.5 kBps but about 550 kBps(due to download manager in the browser). Had to use Firefox instead of IE6 to download new version of firefox browser, yesterday.

We have to try different browsers and see if wifi data transfer speed is limited by software and number pf people using the download server? Install download manager in the browser may speed up the data transfer. Webpage download may also be helped by download manager operation.

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

I have switched to RCN cable modem by ARRS. Using WinXp operating system with wpa2 aes password encryption.

Have to throw out all my orinoco collection of wifi pc-cards.

Linux used to be able to use all the orinoco wifi cards at 11 mbps, but new browsers only connect on 54 mnpc speed. Only a few wifi devices came with linux drivers Ralink Dlink brands.

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

Many wifi devices are easily connected to the internet if no encryption is used. WEP of 64 and 128 bit encryption is obsoleted by video encryption of upto 10 bits by online banking websites.

WPA-psk is also obsolete. Now people use wpa2-psk(aes) with passphrase to get on cable wifi service.

New list of wifi cards to use will need google for wpa2-aes compatible drivers.
