Replacing T400 wireless card

2009-06-16, 3:27 AM

Hi all, having purchased the T400 with the thinkpad wireless, I have found that it is COMPLETELY unsupported in linux.  In order to make it compatible, I have decided to replace the wireless card, which according to a different thread is not difficult.

 

I am, however, concerned about the specific card that I am going to put in.  Currently, I am looking at this one: http://www.amazon.com/Intel-wireless-3945ABG-Network-Connection/dp/B000EDQOK8

 

According to the other thread, the thinkpad bios only accepts cards with certain hardware IDs.  Will this card work?

 

Thanks,

anstmich

I am also considering this slightly better card: http://www.amazon.com/Wireless-Wifi-Link-Mini-Card/dp/B000QAY00K/ref=sr_1_2?ie=UTF8&s=electronics&qid=1245129823&sr=8-2

 

Will it work?

Welcome to the forum!

 

A non-Lenovo card (including the ones that you've linked) will trigger a BIOS error that will prevent the machine from fully booting...

 

I don't know what distro you're running, but "thinkpad" cards are Atheros-based and generally have a very good Linux support.

 

Hope this helps.

Cheers,

George

It appears that they recently updated the wireless card in the T400 and it is now based on a realtek 8172 chipset.

 

Is there no way to purchase a new (non-USB) card that is compadible with the T400?

 

EDIT: I am running arch linux, by the way, and have tried madwifi with the ath_pci and ath5k modules.  Neither of them allow the system to recognize my card.  Running an lspci -vv indicates the card's chipset.

ajkula66 - That would certainly seem the case, but I recently installed a 3945abg card from a Gateway and no BIOS error was shown. However, I wasn't able to get it working. Could this be a new technique implemented by Lenovo of allowing the card to be installed but not utilized?

 

As I was recently interested in buying a half-height mini-pci express card, I looked at this one. According to the seller, he was able to get it working on a ThinkPad but doesn't mention which one. Also note, it is for a Dell. Ultimately it's your call on whether or not to try it. I know I certainly would try the one I linked to.


The Intel 5100 removed from another T400 should work.

Also note, that the Realtek RTL8172 wireless card used in your ThinkPad must have been released not that long ago, as Realtek doesn't have any drivers listed on its website. I believe the RTL8172 falls in the RTL8192SE family and thus requires the RTL8192SE driver.

I have ndiswrapper loading a very specific rtl8192se driver in linux (opensuse latest milestone)

 

 

The driver link is here: http://www.station-drivers.com/telec...ivers.com).exe

I used wine to extract the exe directly in linux as i didn't have a usbkey handy to copy it over.

Same ndiswrapper commands as before, brought up wlan0 (not using Ubuntu, but the latest OpenSUSE milestone). Looks like encryption does not work, but I'll tinker a bit.

Hi! Good news, look here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/401126 (comment #15).

I compiled OK under ArchLinux 64bits, but I can't see any wireless network :s
