I just installed Ubuntu 12.10 alongside Windows 7 and it seems a little lagged, running a bit slow. I attempt to check for uploads and plugins for Rhythmbox and Python, and it shows there are updates, but it gets stuck.
Also, the wireless icon shows that I'm connected to my wifi network, but I can't load any site.
I'm a beginner here, don't know if there's a way to fix this or if I should reinstall Ubuntu. In that case, is it possible to reinstall Ubuntu alongside Windows 7? How should I do it?
