Hi guys,Airtel had replaced my old router for a new one cos of some technical issues. However ever since I have got the new router I get awful connectivity in the house. For example I can't even connect to the net from the room across me. I thought there is a problem with my laptop and Apple changed the Airport card but even after that I still get the same issue. While I can easily connect to all my neighbors wireless networks except mine.On calling CC, the guy wasnt even willing to hear me out and insisted that wifi connectivity works only in areas without walls (wtf). I told I havnt come across any house which doesn't have walls and this issue has never cropped up in my 5 year usage but he was a complete ass and then even disconnected the phone.Is there anyway to fix this issue and does the wall argument hold true?
