So i have a linksys router and i just realized,i have NEVER had a modem,throughout all these moves we've had,and i thought you NEED a modem.So please,explain this to me....We have moved 3 times,2 times in an apartment,and 1 time in a house.And all throught those times we have had no modems.We have a vonage adapter so we have vonage phone service,but it isn't a modem,and through all the moves,we have always had the cable from the wall directly into the router,and our internet service providers,starting from first skybeam,to (I don't remember),to xfinity,and now to front range internet.And we had the guys comeout sometimes for each of the isps for a networking issue we had,and they said we don't have a modem anywhere,and the issue wasn't because we didn't have one,just some of the cables were either unplugged or cut.I read online everywhere else and they all say i NEED a modem.But it goes from the wall to the router internet port,to the lan out to the vonage.Thanks
