Question about NetGear WNDR3700 Router

1 Answer

I just baught the Netgear WNDR3700 router today and only after 10 minutes after I had it installed it, it started losing connection. Sometimes I can play games online for 30 minutess and sometimes only a few seconds, harder to tell when I'm just surfing, but I think it's the same. Sometimes the losses are quick and I only need to wait a few seconds without doing anything and then I can use my web browser again, usually after re-opening it. But sometimes I need to disconnect the internet from the pc, and then re-connect again. I havn't had to restart the router yet. I thought it might be some problem with my wireless network card, but my sister has just the same issue on her laptop, so I strongly doubt it. Also when I logged into the router from my pc, it automaticly downloaded an update, not sure what it was, but after that I tried to reset the router since I had read it can work better after doing so, but still no luck. I'm on windows 7 64bit. Any good step-by-step guide to fix these connection losses?

If it is this new I would suggest calling Netgear and have their support help you out. Due to the way their warranty works that would be best. I have a netgear router and hate it. I wish I had taken it back as soon as I had trouble. I also out sourced my problem and keep fooling with it, till it was to late to return it and the warranty ran out. Netgear is the hardest most difficult routers to deal with. May or may not work with AT & T DSL they will not tell you if that is the problem or not. Tell you it's your wireless phone or your neighbors who knows, In other words they do not know what causes these problems. Sorry for your trouble with Netgear.
