Hi, I have already sent an bug-report "iwl3945: Network dropouts w/ flash-stream in firefox" in [1]. Unfortunately, the problem still remains, especially when fast-forwarding flash movies in firefox-3.6.3. It seems the wifi-card is hanging and my system needs a coldstart. My wifi-card is an iwl3945 and my access-point is a speedport-w701v. I am using a Debian/sid 32-bit system. Today, I enabled CONFIG_IWLWIFI_DEBUG=y to see what is going on. I stopped networking, unloaded the kernel-module and re-loaded with module-option debug=0x43fff [2]. # /etc/init.d/networking stop # modprobe -r -v iwl3945 # modprobe -v iwl3945 debug=0x43fff The kernel I use is a Linux-2.6.34-rc4-git4 with these 3 patches in addition: patches/wireless-2.6: 0001-iwlwifi-work-around-bogus-active-chains-detection.patch patches/iwlwifi-fixes-for-2.6.34: 1-2-iwlwifi-fix-scan-races.patch 2-2-iwlwifi-correct-6000-EEPROM-regulatory-address.patch According to Johannes (on IRC) iwl3945 doesn't use internal scans yet (see my patch below). Thus, I am not sure if this needs to be fixed separately for iwl3945 and if I ran into a scan race condition here. If this matters: I am using Debian's wpasupplicant (0.6.10-2) and wext wpa-driver. I collected all data and provide them in [3]. Hope, this helps.
