ThinkPad T61p and Intel 4965

Well, here's another issue with Intel's 4965 driver. I'm able to scan and everything, but wpa_supplicant doesn't seem to want to associate. Here's some info:
wpa_supplicant.conf

Hey, I have the same laptop and wireless adapter, and I'm using WPA-PSK on the new kernel 2.6.25-gentoo-r7.

I followed this guide: http://gentoo-wiki.com/HARDWARE_ipw3945

and my very simple wpa_supplicant.conf is (essid and psk removed):

I tried a simpler wpa_supplicant.conf, and used that guide to start with, without any luck. I haven't seen any errors like those, though.

Here's some more useful information, such as starting the net.wlan0 script:

on mine I don't have a phy0, but my wireless led light doesn't work at all

you also have a similar error to mine (the microcode error), near the middle of dmesg, but I'm not sure if that is the problem

iwl4965: Microcode SW error detected. Restarting 0x82000002.

How about checking your ucode?

The LED will only work with 2.6.26, but with the new release i get disconnected after 30-60seconds of using that connection.

Hi, this is my configuration :

Also, after a fresh reboot, can you post that plz :

d2_racing · Posted: Thu Jul 24, 2008 11:43 am Post subject:

Also plz double check theses options :

All of those things are either built-in or compiled as modules in my kernel already.

Here's the output of those commands, in the order you asked for them ($MY_SSID is the SSID of my WPA-PSK wireless network):

Hi, as I can see, your 4965 driver is working properly.

So, first, can you change your SSID, because a _ is a pretty good for a wifi name. In fact, your problem is maybe from an invalide character from your SSID.

So, can you change that and reboot your box

And run this plz :

Also, can you post this before running all the commands :

Kenji Miyamoto · Posted: Sat Jul 26, 2008 1:25 am Post subject:

Well, my SSID is comprised of only uppercase and lowercase letters, and worked with wpa_supplicant on a laptop with an Atheros card a few years back without any issues whatsoever.

I don't have a graphical web browser yet on this laptop, and ELinks doesn't let me do middle-button-paste under X. net.wlan0 is symlinked to /etc/init.d/net.lo, and net.eth0 is symlinked to net.lo (without the path).

Something else: I don't have BSSID, but that Atheros card still worked without BSSID. Enabling BSSID doesn't get the Intel card to associate.

Should I just give up on using wireless with this card and buy something else? What are some good PC Card wireless Ethernet cards for use with Linux?

Use ndiswrapper. iwl4965 is buggy at the moment.

Kenji Miyamoto · Posted: Sun Jul 27, 2008 8:52 pm Post subject:

Unfortunately, this is on a 64-bit system, and I don't have a 64-bit Windows to get the drivers from.

Where should I get them?

Ok, when you run this :

It's exactly the same as before. No errors or anything.

The suggestion of NDISWrapper didn't help, either. I get this:

d2_racing · Posted: Sun Jul 27, 2008 9:39 pm Post subject:

Can you repost your /etc/wpa/wpa_supplicant.conf plz

Kenji Miyamoto · Posted: Sun Jul 27, 2008 10:05 pm Post subject:

Kenji Miyamoto · Posted: Mon Jul 28, 2008 2:58 am Post subject:

Well, it looks like WEP fails with wpa_supplicant, too.

Now I have wpa_supplicant with WEP associated, except no traffic whatsoever can go over the network. Everything is "destination host unreachable," and DHCP won't get an address. What's wrong?

I can't even modprobe ndiswrapper:

Hi, if you want to use a wep key, you need this configuration instead :

My iwl4965 just doesn't work with 2.6.26 so far. Same settings everywhere, but it's still a no go...

d2_racing · Posted: Thu Aug 07, 2008 11:43 am Post subject:

If you want to use the 2.6.26, you need to active the rfswitch kill from the kernel and also enable the rfswitchkill inside the ilw4965 option too.
