Didn't really know where to post this problem??? I have a Philips wireless video sender. It works on 2.4GHz and I use it to send the picture from my freeview box and my DVD player to my TV in the bedroom. Up to now, it's worked great. The only thing that intefered with it was my wireless internet but I'd turn that off when watching the TV in the bedroom. Now though, I'm getting inteference that's almost identical to that I get from my wireless internet. I live in flats and I assumed that someone else has now got wireless and it's interfering. However, my laptop doesn't pick up any other wireless networks and I've also got a network sniffer utility and that doesn't pick anything up either. Is it possible to have a wireless network that is invisible? That would explain why I'm not picking up another network. Also wondered what else could be interfering with it. The interference is constant, 24/7, so it can't be something like a dect phone or microwave as this would cause intermittent interference. Also wondered if there are any senders that work on another frequency other than 2.4GHz? Any ideas anyone?
