Another thing. As this seems a wireless issue it may be better to send
this thread to the linux-wireless list.

In my case, with 3.1-rc9, an atheros SR71 card stopped apparently
negotiating N - as it would not connect faster than 54Mbit on the 5ghz
channel either in HT20 or HT40+ mode, according to sampling iwconfig.

3.1-rc9 wifi problem

[werner]

I'm very sorry that I cannot give more informations, my 
own computer is connected with the modem via ethernet 
cable, a friend used in the past often wifi here at me, 
and since 2.6.38 never with problems, also with 3.0-rcX no 
problems, nor with 3.0.X until 3.0.4 .  There were 
 general problems with 3.1-rcX until 5 , which had nothing 
to do with wifi but what was the reason that I only late 
got working 3.1-rcX , so the first 3.1-rc the friend 
tested on his laptop was 3.1-rc9, and with this his wifi 
didn't work, but I don't know if it would have worked with 
-rc5. When he come back, perhaps next week , then I'll ask 
him to try 3.1-rc5 or 6 .   This is a kernel+modules 
problem, because with re-installing 3.0.4 it returned to 
work as before.  Anyway, I wanted to report this, so that 
before the release of 3.1 the wifi drivers could be 
checked better.

Unless you say which driver is involved, we will n ot be able to help.

Re: 3.1-rc9 wifi problem

[werner]

I have to wait until the friend with the laptop comes 
back, perhaps this week. Then I can look what wireless 
card is in it.

However, now I remember me:  that laptop worked only good 
since 2.6.39 with the new kernel-embedded modules. 
  Before, it didn't work normally, i.e. on booting the 
wireless almost never didn't switch on; only ocasionally .


And, beside of kernel 2.6.39, and the normal wifi 
software, I still had him to install a file 
iwlwifi-1000-3.ucode or .5 ucode (i'm not sure, the number 
can also be 5000), and I had the problem to search long 
time for that file because one find only .2 or .4 in 
internet but what don't work at that wifi card.   You 
could improve the kernel-module so that everything is 
included so that one don't need to search such files.

Then, with this kernel and that file however, it worked 
without any problem.

I hope from these informations you can find out what wifi 
card or what driver is in the laptop.

Not knowing much about what problem you  encounter, but you can find all
the latest intel WiFi firmware at

That will not happen. In fact, the trend is from having firmware be a part of 
the driver to having it be external.

I don't know what distro you use, but mine (openSUSE) maintains a package called 
kernel-firmware that contains all the redistributable firmware that is available 
from tne linux-firmware git tree. If that package is installed, then you do not 
have to search for firmware in most cases. If your distro does not have such a 
package, then complain or find another distro.

We can tell that you have an Intel card, but not much more.
