Cannot connect Dell D610 laptop wifi with Ubuntu v11.04

[London User]

Hi everyone - new user here,

I recently switched over a home desktop PC and laptop computer to Ubuntu (v11.04) from XP and love it for both.

Unfortunately, I've got an unresolvable issue connecting the laptop (Dell Latitude D610) to the home wifi network. The laptop broadband can be connected via an ethernet cable but not the wifi. I've searched the forums for answers and have downloaded and installed the b43 driver which enabled the router to recognize the laptop wirelessly. I just can't seem to actually use the Internet. I've got a double 'no' for hard and soft blocked.

Any ideas anyone? I read the great exchange between chili555 and Dom/djavet and tried some of those suggestions but I think Dom's issue may be different from mine although I'm not sure < http://ubuntuforums.org/showthread.p...dell+d610+wifi >.

Thanks in advance for any assistance!

I have a D 610, and wirefree worked out of the box with Ubuntu 10.10 and Xubuntu 11.04. Since it worked by itself I can not tell you what I did, but if you want to 'have a look', you are welcome.

Else I guess best is to post in the other thread. Seems to be given first class advice there.

system is able to detect your wireless card. Usually at the top right corner of the screen there will be a network icon. click on that and see, if you are able to see the wireless networks

Yes - thanks, but that is not the issue here. My laptop recognizes and connects to the home WiFi (and recognizes others WiFi signals in the area) but my laptop won't connect and allow 'surfing' of the web. What could I do to 'connect' that final step?

Thanks again!

Hi Everyone,

I'm going to end this post and try a different one as I think this one has run its course.

Thanks for all the help so far!

What is the network status after you connect to the wifi network. Connect to the wifi network and execute

ifconfig
iwconfig
route -n
