Wireless disappeared
I've got a problem with the WLN connection on Ubuntu 8.04 (same problem appeared in 7.10, before the upgrade). Sometimes at the start-up no WLAN is detected... then, apparently after no reason (for my understanding) after a e-boot the WLAN is there again. Lately I didn't manage to have it back working.
I have the feeling the W-card is not detected: it is a Gigabyte GN-WP01GT. Further info: iwconfig gives: lo no wireless extensions. eth312 no wireless extensions. lspci: 00:00.0 Host bridge: nVidia Corporation Unknown device 07c1 (rev a2) 00:00.1 RAM memory: nVidia Corporation nForce 630i memory controller (rev a2) 00:01.0 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.1 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.2 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.3 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.4 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.5 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:01.6 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:02.0 RAM memory: nVidia Corporation nForce 630i memory controller (rev a1) 00:03.0 ISA bridge: nVidia Corporation Unknown device 07d7 (rev a2) 00:03.1 SMBus: nVidia Corporation Unknown device 07d8 (rev a1) 00:03.2 RAM memory: nVidia Corporation Unknown device 07d9 (rev a1) 00:03.4 RAM memory: nVidia Corporation Unknown device 07c8 (rev a1) 00:04.0 USB Controller: nVidia Corporation GeForce 7100/nForce 630i (rev a1) 00:04.1 USB Controller: nVidia Corporation GeForce 7100/nForce 630i (rev a1) 00:08.0 IDE interface: nVidia Corporation Unknown device 056c (rev a1) 00:09.0 Audio device: nVidia Corporation MCP73 High Definition Audio (rev a1) 00:0a.0 PCI bridge: nVidia Corporation Unknown device 056d (rev a1) 00:0b.0 PCI bridge: nVidia Corporation Unknown device 056e (rev a1) 00:0c.0 PCI bridge: nVidia Corporation Unknown device 056f (rev a1) 00:0d.0 PCI bridge: nVidia Corporation Unknown device 056f (rev a1) 00:0e.0 IDE interface: nVidia Corporation Unknown device 07f0 (rev a2) 00:0f.0 Ethernet controller: nVidia Corporation MCP73 Ethernet (rev a2) 01:06.0 Ethernet controller: Atheros Communications Inc.

Anyone out there can? |
Hey Onit72,
Have you tried using add/remove application to download one of the wireless Lan management tools such as KWiFiManager or SWScanner. I had the same problem on two computers but it was fixed by doing this. Let me know how you go. |
Check out the madwifi-hal package. It solved my Atheros related problems where the standard madwifi package didn't.
|
I tried first to install the madwifi-hal with the following procedure (found on the web) as it was the fastest try:
"gksudo su cd /usr/src apt-get update apt-get -y install build-essential linux-headers-$(uname -r) wget http://snapshots.madwifi.org/madwifi...0080903.tar.gz tar xf madwifi-hal-0.10.5.6-r3861-20080903.tar.gz cd madwifi-hal-0.10.5.6-r3861-20080903 make make install echo ath_pci | sudo tee -a /etc/modules modprobe ath_pci " After a re-boot nothing changed. If no other ideas I can try to replace Network Manager. |
