How to re-Connect to Wireless Nework.


For weeks whenever I booted into Ubuntu 9.02, my WiFi card was detected automatically, and I was online. Suddently, for some unknown reason, this is no longe the case. I do not know how to configure it again. Previous to this, I was having trouble with my panel. Whenever I have real problems, I always return (home) to this forum that helped me install my Ubuntu.

Thanks in advance

It stopped working at the same location where it was previously working? Are you sure the router is not the problem?

Have you done any Ubuntu upgrades recently?

Anyway, I work from a terminal window for wireless config (as root):

ifconfig - this will give you the current status of the network interfaces on your computer. See if you can find something that looks like a wireless interface (usually "wlan0" or something similar).

iwconfig may provide some additional information related to the wireless interface.

ifdown wlan0 (or whatever the name is)
ifup wlan0

This will "reboot" the wireless interface - sometimes this will be successful.

If that doesn't work, post some additional data on your system. The output of iwconfig would be helpful.

Thanks, but can you be a little more specific about what I should do. This is all new to me. It would be helpful if you could simply tell me what to type, or better yet, I can copy/paste it.

Thanks

Here's a troubleshooting guide I found that talks about iwconfig.
