Updated to 10.04 on Friday. Saturday, signed in and found no wireless icon in taskbar and no connection to internet What happened, and how do I fix. All other computers on LAN are fine. Thanks Erniebob
what type of wireless card? Run this please and post the line related to your wireless card:
sudo lspci -nn
The previous 2 versions of Ubuntu worked fine with my wireless, but 10.04 installs the wrong driver for my Broadcom 4312. If your wireless card happens to be a Broadcom 43xx type, I had to do the following:
(1) connect your laptop to a wired connection, then run...
(2) sudo apt-get install bcmwl-kernel-source
(3) sudo reboot
Results of sudo lspci -nn:
01:00.0 Network Controller  RaLink RT2800 802.11n PCI [1814:0601
hope this helps.
Does your problem appear to be the same as this open bug?
I don't know. This is all Greek to me.My wireless worked perfectly with the earlier version of ubuntu Now it does not. Is there any way to return to 9.8?
