The only solution would be buy Atheros etc card?
But my on-site …

Seems iwlagn driver is one of the worst Linux driver I’ve seen – this driver blocks the whole machine for 15 secs! (ha ha)

Also EU is not supported at all?

There must be some off-by-one bug for finding wifi channel..

I’m running iwlagn with 11n disabled, and channel 13 is used because 1-9 are heavily used here, resulting 50kB/sec transfer rate (max).

I believe this is fixed

Thank you.

Unfortunately the 2.6.28.8 kernel didn’t solve the problem for me.

I must have tried 6 different kernels, about 10 combinations of module parameters, 5 different versions of the NVIDIA driver from their website, running with or without the power setting script. Sometimes it seems to work a bit better, and then again, after a while, the errors come back.

When I have the time, I’ll try another operating system to see if it in my case actually could be a hardware problem.

as promised I tried to copy some bug files through wifi. Yesterday I transfered 7.8GB on a stretch without changing the power levels (where set to maximum) and I did not experienced any microcode errors. The test was done using 2.6.28.8. Let me know, if I can provide more data to help you to solve the problem.

Cheers,

I didn’t try to copy large files for some time now, so the current status of working or non-working is unknown to me. In fact it will ever be (I guess) since earlier I experienced a working adapter for days and then all of sudden I get these errors once every 2 minutes.

I try out tonight again and let you know. In the meantime, here are the version numbers you requested:

* kernel 2.8.28.8 (I will also try 2.6.29.1 tonight since I compiled it just 2 days back)
* nvidia-kernel-common: 20080825+1
* nvidia-(glx|kernel-source|kernel-2.6.2(8.8|9.1)): 180.29-1
* Nope the script to adjust the power level is not active
* I dont put any parameters while loading the module. I guess it takes dafault values. Tell me how I figure out the settings and I’ll let you know

Is the solution still working for you? If so, I’d like to know the following:

* Do you run the default iwlagn driver for the 2.6.28.7 kernel?
* What version of the NVIDIA driver are you using?
* Are you still running the script that changes the power level setting?
* What parameters do you load the iwlagn driver with?
* Anything else that you may have found out to be the solution?

I’ve had this problem on my T61 for a long time now – every solution I’ve tried has failed. So if you could help me, I’d _really_ appreciate it. Feels a bit wrong to have to carry along an external USB Wifi adapter all the time..

Thanks in advance.

very strange. For a few days I dont have any issues anymore. I copied several GBs through the wireless link without any error. Although I didn’t change anything regarding the iwl-module. I dont have any problems anymore, since I removed the nvidia driver from the blacklisted modules and boot the kernel (2.6.28.7) without any parameters, so that all messages are printed out to the console. (previously I started the kernel with “root=/dev/sda2 ro resume=/dev/sda5 quiet”) I have no explanation for that.

Neither did the 29rc7.

What did help was to downgrade iwlwifi-4965-ucode to the 228.57.2.21 version. It doesn’t solve the issue, but at least, the problem is less frequent and the temperature is much lower.

I think is a regression on the kernel since 2.6.28.3 and the new firmware. But I dont like the idea of using such an old kernel… although I might give it a try if this thing keeps popping up.

unfortunately I thought, this was a solution. For a day or so it was working flawlessly. could copy data like anything. However next day, same problem. Let me know, if you had any success with the 29rc7

I’m also building the 2.6.29 rc7 to test with it.

Did you had positive results with this settings?
