Windows 7: slow internet when wired to router

Windows 7 x64 Home Premium
 
 
EXACT same problem!

I have the EXACT same problem! And it's driving me crazy!

I am using a Netgear Rangemax 3700 (but same problem with the 3500). When connected DIRECTLY to my modem, my Windows 7 x64 Home Premium machine gets about 13Mb down (I have a 15Mb/768Kb DSL connection).

When going through the router, I'm lucky if I get 256Kb down (upload speed doesnt't seem to be affected that much).

Interestingly, my MacBook Pro connected to the router WIRELESS is getting about 10Mb down!

ping to Google in both setups yields about 63ms.

Have you guys sorted out what the problem could be?

Here is my ipconfig:

Hi Stele

I could not find the answer in these forums. I have found the answer now but I'm not sure if it will apply to you. My solution was to go and buy a new PCI NIC (a cheap 5 job from novatech). Everything now works fine and as you would expect it to. I still don't understand exactly why this solution worked for me because I'm not entirely convinced it is as simple as a hardware fault on the NIC built into my motherboard - I still think it is software related but after months of trying everything I could possibly think of I thought it would be worthwhile forking out a fiver 'just in case'.

One thing to try though - can you connect up the MacBook Pro through the network cable to the router? - if this suffers the same slow downloads as your Win7 machine then it must surely point in the direction of the router. If the MacBook when connected via a cable doesn't suffer the same slow downloading then I think it might be worth you sticking a 5 NIC into a spare PCI slot and see what happens.

Good Luck - let me know when you manage to fix it

Thanks for the reply. I doubt it's my NIC, since I am getting full speed to the modem when I bypass the router.

The Mac plugged into the router without wireless also streams perfectly.

It's something Windows 7 specific, when going through the router.

You're right, I don't think it is your NIC, same as I don't think it is my motherboard NIC that was at fault, but until I can find the source of the software issue, the new NIC works for me

Sometimes certain brands of network cards have a hard time connecting to certain other brands of routers. The difficulty seems to be related to negotiating a protocol. This could be a difference in implementation of the standards.

As a shot in the dark, this issue sounds like a difference between full duplex and half duplex (NIC to Router) causing collisions... As a computer operator, we had to get into the habit of explicitly setting both NICs and Switches to full duplex instead of letting the components negotiate the protocol. I forget exactly how to do it, but a little searching may provide a methodology for your card and/or router to hardcode the connection parameters.

Cannot get Internet connectivity on wired router.
I have reinstalled W7 due to this issue. It seems that W7 only gives an option to setup a PPoE connection ONLY if it requires a username / password. There is no 'always on' setup that I can find anywhere. Of course there is no such problem on my XP partition. Any Ideas? Thx peeps! :cry:
