I'm having a rather strange but annoying problem with my ubuntu machine. We recently had to change routers from an o2 one to an old router we had lying around. Well we managed to get it up and working and I was able to connect fine on ubuntu. Then one evening late at night I turned on my laptop and was unable to connect. I went to bed and by the morning my laptop connected again. When I got back from work in the afternoon I was also able to connect and was connected until I had to restart my laptop around 10pm, after which I was unable to connect again.
All other machines in the house are having no connection troubles and the only variable I seem to see is the time of day. This is somewhat frustrating as I have to keep my laptop on all afternoon and evening if I want to keep connected!
Any help would be much appreciated
