Looks like wireless on linux is still 'iffy'. I have a Dell E1705 with the Intel 3945 wireless chipset. Just installed SL 5.2 and did all the 500+ updates. On 4.2 I had working wireless. But not now. When I tried to change over to wicd and start it, I received:
* Starting wicd daemon... sed: can't read /etc/wicd/wired-settings.conf: No such file or directory
Had to go back to NetworkManager again. Does anyone have the Intel 3945 and have working wireless on 5.2?
