|1.If you try a transfer between 1 and 2 or between 3 and 4 is it still 10 meg ?|
Yea I had tried both scenarios. I also tried between 1 and 2 just using the switch with the router disconnected, same difference. Both routers are supposed to be 10/100 (just doublechecked product specs again), and all the nics show up in network connections as 10/100. I have also checked to make sure 'auto' is selected for each.
2.Is the second router connected via its wan interface?
No, connected at both ends through LAN ports.
3."I consistently get transfers limited to 10 Mbps (everything should be 100 Mbps capable)"
How are you determining this?
I was doing it by beginning large file transfers (both of large single files, and folders containing a number of files to see if that made a difference); letting the transfer run for a few minutes to stabilize, then taking the filesize, converting to megabits and dividing by elapsed time + estimated time remaining.. calculation always gives me between 9 and 10 Mbps.
4.Try hard setting both sides of the link to 100/full
Will try this in the morn.
5.There should be a setting on the switch to change the port to 100/full duplex, and/or you also need to set the computer link under the nic properties in device manager
I haven't been able to find a way to manually set in the config pages of either router. I may also try flashing the firmware on the DI-604 (since I don't remember problems before it was hooked up; though I can't be sure when this really started)
Thanks for the suggestions so far..
