I have a UK BT Internet wireless router with WPA security in my apartment. I connect various devices to this router with hard wires (PS3, Xbox 360) and wirelessly (iMac, 2 x iPhones and 2 x iPads).

I have no internet issues at all - it works all the time on all my devices.

However, in recent weeks the iMac cannot keep it's wifi connection to the router - it drops out intermittently for no reason.

I have installed Lion OSX and have tried restarting both the Router and Mac several times but it hasn't sorted this out.

Please help.

Thanks

Do you have all the latest software and firmware updates installed? (Apple menu > Software updates)
