i have a laptop that is showing that it is connected to the wireless router and when i try to connect it wont. All my other computers work with the wireless router. Ive tried it at my dads house and its the same problem but took it to a computer shop and they connected straight away. It connects straight away with cable. It has worked before and been sent away for new keyboard and kapersky upgrade but nothing else. I have tried everything, ping, ip address ok. Anyone got any ideas?????
