Had this router for few months working fine, than the modem was slow for our house so we got a new modem called Actiontec Model#GT701D. And we did the Set up but the Internet doesn't work anymore. If we connect the modem to Pc, it works but connecting modem to router it doesn't receive Internet. Another problem wad that for the DIR655 to work we needed to connect another router before DIR655 connected to modem, so we needed to have an extra router to get the DIR655 to work. Anyone got a clue what to do?
