Since I bought this computer last year I have been having trouble with wireless.
It connects but after some time (sometimes minutes, sometimes hours) the connection breaks. Sometimes using F11 to turn off and on the power resolves the problem sometimes a full reset seems to be needed. It is a very frustrating problem that makes me want to go back to Mac... Anyhow not yet giving up
Other computers (Mac & Windows) have no problem at all to have a stable connection with the same wireless router. Resetting the router does not help in any way. Even plugging in an external usb wifi card (one that works fine with other computers) is not solving the problem. So it seems the problem is software related.
In an earlier discussion directly with support last year I was told to reinstall Ubuntu. Doing this did not solve the problem. The computer has the Ubuntu LTS version 12.04 installed, and all updates are applied.
Any help would be really appriciated.
