ubuntu question: wifi wont connect

unplug your wifi router for a little bit and then plug it back in.

it needs to find your network.... typing it in by hand won't help ya much if it doesn't see it. crack open terminal and do this: look for what essids it found...is yours listed there? are any listed there? if yours is there you can connect to it via the network manager or via terminal with "iwconfig eth1 essid ESSID" and then doing "dhclient eth1"

Hi can't connect to di-524 using your guide above. Under windows its no problem. system is edgy eft. Using Wifi-radar or networking under administration doesn't help either. It says I'm connected but there is no data flowing. Plugging in the router by cable internet works instantly.

Now i am very new to linux, and just started!!! But i have tried Ubuntu, Kubuntu , Xubuntu , PCLinuxOS , Freespire , openSUSE , and Knoppix and the only one that worked was Novell Suse Linux Enterprise Desktop 10. I have a Dell Inspiron 6000, with a Intel PROWireless 2200bg and a DLink DI-524 router. With WPA-PSK Security, i spent ages trying to get it to work (oh i was close to throwing it at the wall and getting a ThinkPad T60) But i am happy to pay $50 for SUSE and you get support. I would recommend it, but i am a newbie so i needed support
