seriously tho we tried to get a real modem, and they said that we did not need one as the set top box was more than adequate

have found that i need to unplug the router if it drops the connection ... it then sorts itself back out and off we go .. so still seems like a ntl problem, rather than the router ..although i could be wrong .. have tried looking on many sites to see if its ssummit i have done wrong but not foound any conclusive proof yet ...
