As for the PS3 thing... it's literally only the Surface Pro that's got a shit chip in it unfortunately. The PS3 obviously has a better one (of course, more room inside) which doesn't create a conflict.
I have the same issue with bluetooth when connected to a 2.4gz network. However, when I connect to a 5hz network, I consistently get dropouts, and "limited" connectivity.
Does anyone have any suggestions to avoid this?
