I just recently switched from Windows 7 over to Ubuntu 12.04 and have been experiencing some issues connecting to my home's wireless network.
The only way I can get it to connect to the network is by disabling IPv4 and IPv6 settings. Even then while it says its connected to the network (3 bars), I'm unable to access the Internet.
It connected for a little while after I first installed Ubuntu, but after the first reboot I haven't been able to access the web at all. I have very basic knowledge when it comes to computers and barely any when dealing with Ubuntu and Linux.
I'm very happy with Ubuntu apart from this one issue, as before my computer was overheating and crashing, I've yet to experience any of those problems since installing Ubuntu. The information I can give may be very limited since I'm having to use my cell phone to figure out the solution to this. Any help would be greatly appreciated. Thanks in advance!
