I have a fairly new Asus RT-N12D1 router and it works fine except when I transfer files from one computer to another on my home network. The data rate is often <200KBps.

This is over a cabled connection for both computers - cable to the router and from the router. In other words, no wireless connection involved.

Using any other router I've owned the data transfer rate is usually about 5.5MBps.

OK - this is odd. I just tried another transfer and this time the speed averaged 1.5MBps - which is OK but still 1/3 of what I usually experience.

Anyway, Qos is off and I can't find any reason for the slowdown.

If I plug in the old router the transfer speed immediately returns to 5.5MBs or so.

And I just tried another transfer and the rate is back below 200KBps.

WHen you plug the "new" RT-N12, go to your computer's "Network" properties, and check connection speed. I think you can check it from router' config pages as well.

With the "old" router, it was 100mbps (megabits/sec), and transfer speed of 5.5MBps(megabytes/sec) is quite reasonable.

RT-N12 LAN ports are 10/100 as well, but there could be some mismatch on the nodes.

Hi. Thanks for your reply.

I went to Network Connections and to the settings for the adapter/connection (a right click) and got the Local Area Connection Properties; then clicked on "Configure" and "Advanced".

Under "Speed & Duplex" the setting was "100 Mbps Full Duplex"; I changed this to "Auto Negotiation" and that seems to have fixed the problem.

Transfer rates are now 5-6 Mbps - which is pretty much what I've had with every other configuration (i.e. router).

It's a dual-boot computer and before doing the above ^^ I did a couple file transfers when booted to Linux - and they were all as fast as usual. So, something with Windows 7 and this router/network adapter.

Anyway, the problem is solved. Thanks again for your input.

I feel silly - but how to I mark this problem as "solved"?
