Hi,
I've got a simple home network comprised of two computers running Win 7 x64. Both are equipped with Gigabit network adapters. Both are connected to the router via CAT6 patch cables. I don't use the wireless capability.
- The internet works fine on both machines.
- When I bypass the router and instead connect both computers together with a crossover cable, I get transfer speeds of 113MBps to 122MBps (that's Mega Bytes not mega bits) from both machines, indicating to me that both Network adapters are working fine and that the TCP/IP protocol is doing it's job. I'm testing this while no other processes like virus scans or internet downloads are taking place.
- Now when connected to the router, one of the computer transfers at that same 113MBps range while the other drops down to 16MBps. Again, this is tested transferring the same file, while no other processes are going on.
I've got the latest Firmware on the router and latest drivers on the NICs.
Can this be explained, resolved or should I RMA the router?
Thank you.

Is QoS turned on? Turn it off if it is.

The QoS packet scheduler service or in the router setup?

QoS in the router...
-
Ok, I'll try that. Any explanation as to why it could affect only one computer and not the other?
-
Not sure. I would do this if you want to use QoS, setup Reserved static IP addresses in the router for your connected devices. Then set up QoS if you need to. Could be that QoS is enabled however is not associated with any IP address for a connected device. If you don't need QoS, leave it off.

You should try with 2 totally different files from 1 machine to another as one machine may be caching, resulting in a false reading.
-
QOS mainly effects upload speeds that are going out the WAN port, it shouldn't be doing much to internal traffic over the LAN ports.

I've tried that believe me. I've tried many different files. And again, letès not forget that with the crossover connection, all is well.

Ok, so I reset the router to factory defaults and reconfigured it from scratch and that did the trick. Both computers are now transferring at proper speed.

Remember to save of the new config to file.

I´ve have the same issues, but the maximun speed i get it´s 35MBps (megabytes per second).
Can you tell me exactly how do you do that trick.
Thanks

How is your router set up?
How are you connecting? Wire or wireless?
Any 3rd party security software installed?
What OS versions are you using?
