I'm not totally sure if it is only elementary OS or all Linux distributions.
I been seeing this for months but do not have a clue about the reason. When I use a computer with elementary, my router reboots, on something like 1 time per hour. I have two computers with elementary OS being used everyday, when I use OS X everything goes fine, until some computer with elementary gets powered on, then, the pattern begins.
there is some way I can diagnose this?
