[opensuse] WiFi problem - laptop on/off switch
Hello listers, I have a laptop (HP dv2035us - pavillion) with both OS 11.2 and 11.4 installed. The wireless works in 11.2, but not in 11.4. It has an Intel Pro/Wireless 3945AG/BG chip. The laptop has a wireless on/off button at the front left. When I boot 11.2 (KDE) the wireless light does not come on, but then if I turn the wireless switch off and then back on again, the wireless light comes on and it works. However, on 11.4, the wireless will not work, even after playing with the switch. The stock 11.4 kernel, the regular updates nor updating to Evergreen 11.4 made no difference. Since the wireless light does not come on, ifconfig shows only lo and eth0 - no wlan0. The behavior with the on/off switch also used to happen when I had OS 10.3 on the machine. It was a bit annoying, but the wireless could be made to work. The wireless modules loaded at boot are - in 11.2: iwl3945, iwl_core, mac80211, cfg80211 in 11.4: iwl3945, iwl_legacy, mac80211, cfg80211 I suspect a missing package or configuration problem, and I have googled but I am visually impaired so I have not been exhaustive at it. I have looked at dmesg (nothing seems seriously off) but not other logs. Any pointers would be appreciated, Gustav -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hi Gustav, According to <http://wireless.kernel.org/en/users/Drivers/iwlegacy> 'iwl3945' and 'iwl_legacy' are correct.

No problem, Gustav. It seems this can be quite a troublesome card. Fortunately that means lots of troubleshooting threads in various archives to study. :-) I don't have the same hardware nor further time to spend on it today, but I've tried to help narrow down the search field a bit.

Carl Thanks very much for the pointers. I'll do the searches through those URL's and post the result here if I have some luck. Gustav.

Carl Hello,
This is what I did to get the wireless up and running. I looked into the links suggested by Carl. I had previously tried both network manager and ifup. I had looked into dmesg, but obviously not completely. linux-rr0f:/# dmesg | grep iwl [ 317.392396] iwl3945 0000:05:00.0: PCI INT A disabled[ 252.125595] iwl3945 0000:05:00.0: Card state received: HW:Kill SW:On[ 252.128064] iwl3945 0000:05:00.0: Not sending command - RF KILL[ 252.128076] iwl3945 0000:05:00.0: Error sending REPLY_RXON: enqueue_hcmd failed: -5[ 252.128084] iwl3945 0000:05:00.0: Error setting new configuration (-5).[ 252.129010] iwl3945 0000:05:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x040003DD I then googled for the these error messages. I installed rpm of rfkill (for opensuse 11.4). Then as root entered command "rfkill unblock all" Then rmmod iwl3945 Then modprobe iwl3945 with options iwl3945 disable_hw_scan=1 (this is not the exact command). Those two steps got things working. ifconfig wlan0 up finally brings up the interface. But still I could not get Network Manager to work properly. I switched to traditional method with ifup Configured the wireles card/network in Yast. rebooted and the wifi light came on and I was connected to the network and could ping the AP. I ooked in this page https://en.opensuse.org/SDB:Tracking_down_wireless_problems#wpa_supplicant helped me configure wpa_supplicant.conf and the last step i had to do was take down both eth0 and wlan0 and then bring wlan0 back up with ifup wlan0.
