Wirless not working on T61p

[mariner]

I have been using Linux for about 8 years, and for about 3 years I've run several versions of Kubuntu Linux on my T43p.

I have a new T61p, and although wireless networking works in WinXP, it does not work at all in either 32-bit or 64-bit Hardy Heron.

From lspci -v:

However, when I call up knetworkmanager, it tells me there are no active devices.

(I know, lspci says I have a T51, but every other device with a "Subsystem" line shows T61. Maybe this is significant?)

What have I missed?

Re: Wirless not working on T61p

Have a look at your /etc/network/interfaces. If there is anything but

auto lo
iface lo inet loopback

Get rid of it and Knetworkmanager will work again.

Re: Wirless not working on T61p

I did, there isn't, and it doesn't.

It looks to me like the kernel recognizes the device. However I cannot energize it; the wireless device light never comes on in either Kubuntu or Knoppix. (It does come on in WinXP and I can connect to the net in XP.)

I can use the switch to turn the PWAN device on and off, and I can use Fn+F5 to energize the PWAN and Bluetooth devices, but the wireless adapter won't start in Kubuntu.

Re: Wirless not working on T61p

It's working in Windoze. Reboot into Windoze and ensure that the wireless connection is up and working (you can cruise the 'Net). Then, before shutting it down, look in the Control Panel for Wireless configuration settings. Make sure that there isn't a setting to 'disable' the device when shutting down the system. You might also want to check your BIOS settings as well.

Re: Wirless not working on T61p

The light doesn't mean much. I've got a T41 purring along on kubuntu, wlan is working beautifully but the lights make no sense to me whatsoever at all...

But first follow Snowhog's advice, Win and BIOS settings...

BTW, if you know the IP address of your router - typically 196.168.1.1 or some such - try pinging it (on the command line "ping 196.168.1.1) and see what it tells you. Other commands that come in handy include "ifup device_name" and "dhclient device_name" (both have to be run under sudo).
