Win7+64bit: nForce 650i Ethernet slow

[ac7]

Hi,

I looked around for some help on other threads, though I couldn't find much of help, sorry for that. First off, I already tried using Fernando's optimized drivers (B.2. "Actual nForce Driverpacks for Win7/Vista"), and didn't see any noticeable changes.

Basically I have a abit Fatal1ty FP-IN9 SLi (nVidia 650i) motherboard, and reinstalled Windows 7 64bit on a new Crucial 64Gb SSD. The SSD is working just fine, my issue is related to network speed which is painfully slow.

I have a wired 1Gbps connection at home: my Netgear WNDR3700v2 (latest firmware) router, is connected to a wall CAT5E cable and the PC is connected with another CAT5E cable to the wall socket. (Note1 below)

I also have a qnap TS-210 connected directly to the router using a CAT6 cable.

Both devices connect at 1Gbps (can see this both on qnap and on Windows connection properties). The this is that the actual speed is very low. The best I could get copying a large file from the qnap to windows, is around 300kB/s, but usually is around 150 kB/s, which under 1% of the availble throughput.

I have tried all sorts of drivers, from the 15.25, 15.35 or the most recent 15.57 driver sets (with uninstalling of the drivers in between). Do you have any recommendations for this issue!?

Thanks very much.


My issue is similar to those found on these other forum threads, but the recommendations over there weren't helpful as well:

- http://forums.nvidia.com/index.php?showtopic=171676

Note1: from what I've read on other forums, the fact the cable is CAT5E and not CAT6 could explain the misbehavior of the board on Windows drivers (Linux users don't see this happening). I will try using a CAT6 cable to connect to the wall socket, though the one on the wall is 5E... Not much I can do there.

Welcome at nForcersHQ Forum!

Since I don't have an nForce chipset system, I am not able to help you.
Have you already tried to use the Win7 in-box Ethernet driver?

Hi!

Thanks for the reply. I had that one installed first, with the same behavior. It's really strange how this issue comes up so many times, I figured someone else noticed it over here, given you have lots of user comments on these boards...

Thanks

Try disabling the Receive Side Scaling setting.

I guess you mean like this: http://technet.microsoft.com/pt-br/library/gg162712(WS.10).aspx

If you notice the screenshots above, one is for the advanced tab, where I don't have any option like that (I think).

Thanks

After much tinkering with my home network, I think there was something "stuck" with my netgear router. After a few resets the LAN speed is acceptable (30-40 MB/s), even though not the maximum possible.
