My Setup:
2 x RB133c with SR9: One in Station mode, the other in Bridge mode. No WDS.
See Picture Below:

I’m having problems with Bandwidth Test.
- Pings OK in either direction
- If I try to initiate Bandwidth Test from either end via Winbox I get “Auth. Fail” Any ideas?
- If I try to initiate Bandwidth Test from “The Dude” it runs. Running in TCP mode (both directions) I get a very respectable throughput and the cards register at 54Mbps. However, if do the same test for UDP I get flatline, zero throughput. Any ideas?
Cheers
