10mb is the best I have been able to make using any combo with a RB112. The problem is always the cpu is at max usage.
I agree with HeadBang
My Set setup
I have the same results when routing traffic from PC1 to PC2 with the RB133c and the R52
Eg 10 Mbit/s TCP traffic and CPU is at 100% on both RB133c
If I set the Radios up in WDS and create a bridge, I can get about 14Mbits/s from PC1 to PC2
While in a routed setup if I do a bandwidth test from the first RB133c to Wlans2 IP I get about 40Mbits/s which is closer to the documented through put, however this is just the radio performance.
It appears that this high speed radio performance is not usable as the CPU in the RB133c doesn't have enough grunt to either bridge or route the traffic out an Ethernet port.
Can someone please confirm the MAX real throughput from the Ethernet out the Wlan interface, this should be documented on all of the routerboards, so people can make an informed decision about which product is going to suit their bandwidth requirements.
Take the 133 Board, 3 Ethernets and 3 MiniPCI slots, it seems if you want to route a total of more than 10Mbits/s across all the interfaces, you might want to consider I higher speced board.
Or in my case if you want to get higher threw put than 14Mbits/s bridged, out of a 133c in a Point to point setup, you will want to consider a higher spec board.
Very frustrating and annoying that this has to be found out by trial and error!
