I've just spotted that my wireless connection on my phone drops after a short while when I'm not actually using the phone. The wireless function remains on, but disconnects from my router, which is a mere 5 feet away (so unlikely to be a signal problem - other wireless connections from other devices remain active). As soon as I switch the screen on again it reconnects. I'm not sure if this is anything to do with the ROM (Oxygen) and a new setting that I am not aware of or if it's something else. Anyone any ideas at all, please?
