Brand new Wndr3700v3 losing connection constantly

I opened it from the box, called comcast to have them put modem/router in bridgemode and turn the wifi off to that unit. I installed the Netgear router in following the directions, i had internet for about 15 minutes then it went out. I called customer support they had me changing the channels switching it to wep then the internet worked again, 5 minutes after that it went out again. So i called back, they had me downgrade the firmware to .18. It worked for another few minutes then out again. At the time of this there was only 3 devices connected to the router only 2 of which that were connected the entire time, my iphone and my macbook pro running osX lion. I don't think i have a faulty unit i hate networking and i'm sure its something simple. heres another thing every time i access the page its losing connection to it says DNS problem, and i am still able to access the routerlogin when the internet connection isn't going through please help!

I know it should work, I plugged it in wired and it's the same no connection. Well let me rephrase the connection comes and goes same was the wifi.

Are you sure the Comcast unit is really in bridge mode? Those Comcast-initiated commands are famous for not working properly.

check pc without the router .. If does not drop the connection at all then it will be on router side. Which can be from WAN side of 3700 and cable modem communication issues

I called comcast twice making sure it was set to bridge. Also yes I plugged the computer directly up to the modem and had signal steady

Re: Brand new Wndr3700v3 losing connection constantly

Ok I was thinking of something. I have no idea how to fix this but something I noticed. Could a pc on the network be messing it up. I noticed that every time this pc would connect that's when I'd have issues. Also on one attempt with routerlogin it said that that pc was handling the information.
