After putting ubuntu 11.04 on my laptop (msi cr620) the wireless will randomly disconnect and then will not reconnect unless you restart it or put it on standby and start it again. Once connected it is very slow to load up pages, even google (I have tried using fedora and it was a lot faster it just seems to be ubuntu).

I'm a newbie at this so I don't know how much of the above is helpful but if anyone can help I would really appreciate it.
