I have an Ubuntu 12.10 installed on a Dell Inspiron 1520. I got my wifi working but the connection to the router drops from time to time. I couldn't figure out yet what's causing the drop.
The connection doesn't recover automatically. Instead, if I disable the wifi and enable it back, it reconnects immediately.
With the other computers in the house I don't have this problem, so it assume it's something related to the OS or the drivers.
Does anybody have an idea what could be wrong? I can provide log files or configurations, if needed.
Thank you.
