Had wireless yesterday but not today
I am new to Ubuntu. I just bought a Dell e1505n that has Ubuntu 8.4 on it, and I have it set up for wireless connect to my Linksys wireless n router. Everything had been working fine then my wife got on there and boom now it only connects if I put in an ethernet cable.
Ubuntu did an update yesterday and worked fine after.
I have tried to manually connect to the wireless using a wep 128 hexidecimal password, everything that I had done before to get on the network, but alas no connect. Please help.
