Lost in the Ethernet

Summary: To make 802.11 happen under Linux with Linksys, you need an access card that works with Linux.

Linksys WiFi PC CardDear Bloggie,

I have both Windows XP Pro and Redhat Linux on my notebook computer. I love using the Linksys WPC54G PCMCIA card with WiFi communications. Unfortunately, this only works out of the box with the Windows operating system. A Google search showed multiple very technical solutions that let the Linksys PCMCIA wireless card work in the Linux world. It seems that Linux support works very hard to show that it can be used as a Windows replacement, except for a few applications that haven’t migrated to Linux. Surely wireless communications isn’t one of those applications?

Would you or your colleagues have a solution that could be used to use the Linksys WPC54G PCMCIA card in the Redhat Linux world?

Tied to Ethernet; Dreaming of WiFi

Dear Tied to Ethernet:

Bloggie can sympathize with your plight.

My son and I just spent an exciting hour crawling through the dirt of our half dug-out basement, trying to run a new Ethernet cable to his PC following a lightning strike that knocked out
our home network.

We had 30 feet of cable. We should have had 50.

While my dirty son thinks about whether he’s going to talk to me again or not, here’s a funny point. Linksys wireless routers actually run Linux commands internally, interfacing with Wind River’s VxWorks. (Wind River even has a complete Linux strategy, which CEO Ken Klein described for us in April.)

UNFORTUNATELY, this doesn’t help you with your PCMCIA card problems. To make 802.11 happen under Linux with Linksys, you need an access card that works with Linux. Besides, PCMCIA access cards are dirt cheap. (Bloggie has dirt on the brain.)

Tuxmobil has a list of such cards that work with its routers. Check with Linksys on compatibility with your specific router before handing over the greenbacks. Then you just plug in the Linux card while running Linux, and the Windows card when running Windows. And don’t forget to get in touch with Card Services for Linux, a complete PCMCIA support package.  

UPDATE: After hours spent in the basement pulling cable, we found the old cable does work. But the son refuses to go back downstairs. Right now Ethernet is snaking around our ceiling like Christmas lights. Help!

Sincerely,

Bloggie

Just In

creative
D T Schmitz 4th Nov 2005
I'd add the ndiswrapper is a pretty darn 'creative' piece of tecnology.

Just need to know how to read and follow directions and try not to set yourself up by 'borrowing trouble', that's all.

But there will always be those who'd just not like Linux because you *sometimes* have to go out to a terminal window to make some tweaks and that's understandable--Linux has come a long way though in terms of isolating the low-level details--as for myself, SuSE 10.0 and Yast in particular is pretty smart at detecting the right drivers on the first try, but it's not a perfect science.

Those who don't have the 'intestinal fortitude' will not likely try it and stay with the status quo. That's ok.

Just don't reject Linux out of hand on the principle of 'poor driver availability'--that's simply no longer true.
Hmmm... perhaps I accidently posted it somewhere else. But I shall repeat. Suggesting someone purchase another card and swapping the cards back and forth for the purposes of using Wifi in with the different OS's is not, to me, an acceptable solution.

How About...
Erik1234 1st Nov 2005
Next time you buy some hardware and want to use it it with Linux, make sure it's actually supported. I'm sure it will work with Windows.

Or, given that he already has a card:
Buy a new card that works, then sell the old one on eBay.

Singin' the blues

before you go 'singing the blues', give the ndiswrapper a try:

ndis this!
D T Schmitz 1st Nov 2005
drum roll please...
ndiswrapper this!:

http://en.wikipedia.org/wiki/Ndiswrapper

In a nutshell, this allows use of an existing Windows driver--works for me!

Later.

That seems more acceptable.
Zinoron 2nd Nov 2005
Though it does violate the condition in the question that was posed about avoiding potentially difficult technical solutions. Though, I would say that it is hard to avoid in general with Linux until it reaches the point where companies are no longer able to neglect implementing Linux drivers of their own.

NDIS Wrapper
doctorjohn3 3rd Nov 2005
You can try NDIS wrapper from http://ndiswrapper.sourceforge.net
Works fine, WPA-PSK encryption not supported though. WEP 64 bit and 128 bit encryption supported.

WPA-PSK is possible
Real World 4th Nov 2005
But it takes more than a little technical ability to accomplish. WPA Supplicant is difficult to implement, but once set up, it works. I currently have it configured to run in that mode at home, but getting it to launch on startup took a small miracle, two recompliations, and required the use of a fixed IP (vs DHCP) on my laptop.

This question is a perfect example of something Windows does better than Linux, and also an improvement of XP over 2000.
