I do not know much about networking, so I need some help here. I have used Ubuntu since 8.04 and my WiFi has worked ever since. I upgraded to 11.04 today. After first boot (with a LiveCD) my the widget listed my home network, but I could not connect to it. It is protected with WPA. I have found some random terminal commands online in case that could help you figure out what is wrong here.

I have been playing around to try and get it around. Since I don't know what I am doing I am trying random things. Thus far I think I have found a way to connect that works everytime.
- Boot the laptop while connected with a cable.
- Disable WiFi by right clicking the network manager
- Disable WiFi by using the physical button on my laptop
- Enable WiFi with said button
- Enable WiFi by right clicking the network manager
- After a little while it connects
Could it be related to this problem?
Any novel ideas on what this might be related to? Is there a setting that isn't properly enabled during booting?
I tried to do the steps above without being connected with a cable on boot (Step 1) but it didn't work. But the moment I plugged in the cable, it must have kickstarted the Network Manager, because it immediately started connecting to my wireless.
I strongly feel that this is issue is connected to Network Manager not being initialized correctly. Any one with intimate knowledge of NM who can enlighten me? Or maybe even tell me how to test reinitializing NM after boot?
