Hello:

I have a router (RouterBoard) on a tower that has an ethernet run of over 350'. I can get communication to the router when I have the router in 10Mb Full Duplex without any problem. However, I need to be able to run the router in 100MBit Full Duplex in order to take advantage of the radios throughput. What do I have to do in order to take advantage of the Long Cable mode in the routerboard? Do I need a routerboard on both ends? Do any switches support the long cable mode of the RouterBoard ethernet adapters?

Thanks,
Ken

You should just turn on the long cable mode. If it does not show that link as 100Mb/s, then I suggest trying another switch at the bottom.

How would you enable long-cable mode i have tried but my software does not seem to have it.
I am using v2.8.11, and a 230 routerboard with the DP83816A chipset
Any help would be greatly appreciated
