Coming Underground

I'm now back from a long period abroad on vacation and work.

Since my ARP issue I've experienced further problems with iwlwifi. Fresh after a reboot I have no problems but shortly after starting any large download, download speed will drop to around 100kb/s. It was both an issue with iwlwifi-1.2.3, hardened-sources-2.6.24-r3 and 2.6.25-r3. It seems like several other people are experiencing this in one form or another. Similar issues with ipw3945 have been reported here, here and here.

For now I've simply plugged in my good old Atheros AR5212 802.11abg NIC and configured Madwifi.

WPA performance is still way below maximum speed but it'll do until the new OpenWRT Kamikaze release later this month.

*SIGH* Now I'm again able to trigger some Kamikaze bug that cause the WRT54G box to reboot under high trafic. I really do look forward to the new Kamikaze release :)

Update: My card is a 3945 and I'm using latest iwl3945ucode-2.14.1.5 in portage.

Try the 228.x iwl4965-ucode, it works a lot better for me. Make sure you're using the SLOT=0 one if you're not on 2.6.27 rc's yet.

I'm sorry to hear of your iwl3945 wireless troubles. I've had perfect performance from an iwl4965 with hardened-sources-2.6.{24,25} kernels (connected to a madwifi-ng AP most of the time). While you're stuck with madwifi, give the minstrel rate module a try. I find it to perform much better than the default "sample" rate module.

I have the same annoying issues. You described exactly what happens to me. I have tried the latest .27 kernels as of 2 weeks ago or so and am trying to build the compat-wireless drivers to see if anything has improved but I can't get those to even build either. Please send me an personal email if you figure out the solution! =D
