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?

Plug one end of an Ethernet cable into the modem's Ethernet output port and plug the other end into the router's single WAN/Internet input port.

you know what lets make this easy and not over think it. power cycle the modem. the modem paired your ip to the PC and now it needs its ARP table cleared so it can give the ip to the router.

The simplest way to add more ethernet ports is to use a network hub and connect it to the Netgear DG834 instead of the Netgear WNDR3700. This does not require any configuration.

You can download and print the manual from the Netgear WEB site.

NETGEAR N600 WIRELESS DUAL BAND GIGABIT ROUTER Model number is WNDR3700

Don't play with IPs; set them all to DHCP.

Hi
Sometime the problem come from the powersupply itself the voltage drop under load causing weird troubles working for a internet provider and sometime we get weird trouble caused by bad powersupply

i would go into internet options in explorer and go to connections, then lan settings.verify that auto detect settings is checked, then click ok. restart pc and try ie.
