Netgear WNDR3700 router problem

post #1 of 4
Thread Starter 
Hiya guys,

I need some help.

I just got this new router for my network at home it is the netgear WNDR3700 router.

It all works great except for one laptop.

I got 2 computer on the cable to it i have always internet acces at full speed 120 /10

I got one laptop with only windows 7 64-bit on it and all the windows updates it get's great wireless reception.

Then i got another laptop that gives me headache. For some reason whenever i start up the computer it loads up goes in to windows and it all works great. Then i have to select our wireless network so i do and it starts connection but then suddenly stops. It says could not connect to the internet. So i press problem solve option it starts searching and it gives me the solution that i need to reboot the router. well i tried that it didn't work. But the strange thing is if i just keep clicking connect i will get like 7-8 errors and the 9 timed it would simply connect and have a strong connection.

I am thinking it is a software error somewhere in the computer. Is there a possiblity on how i could tell the router that whenever that laptops mac adress tries to connect to just let him have a connection or something?

Or what settings do i need to change to just let it connect instead like the clean laptop?

if u have any questions feel free to ask.

Does the problem laptop have a wireless N card? Also try choosing channels that don't conflict with your neighbors if you have a lot of wireless networks near you. Most people choose 1, 6, 11 or auto mode will choose those try channels 7 or 10 maybe on the 2.4 Ghz band. I use channel 10 on the 2.4 Ghz band and channel 36 on the 5 Ghz band.

Oh yeah this seems like a hassle but separate your wireless G devices on a different router if possible for optimum performance for your wireless N devices.

I might have a solution for the now and then network connection drop on the wdr3700.

I noticed that my network resources are still available during the drop, but the internet connection is lost.

After fiddling for weeks I found out what works for me:

In the lan and wireless lan settings, only set the DSP servers according to your provider's IP adresses. THat is in the Internet protocol (TCP/IP) section.

So leave the "obtain ip adress automatically..." alone (obtain automatic or manual pre-set. Not important here.)
And set the "Use the following DNS server adresses..." to your ISP WAN DSP server adresses. These can be found in the status screen of your Netgear router via www.routerlogin.net. Or via your ISP's connection manual.

SInce then, no more connectivity losses for me.

Succes, Frank.
