A mate of mine si having the same problem, in fact he been having the same problem for months. all he get from MAAF is to try another router, so he did, I lent him my speedtouch, but he still having problems. But they still tell him to try another router.
I don't think they can read emails at MAAF, a Awful ISp to be honest, with customer service that is as bad as Talk Talk if that is possible.
