Sometimes you can have a very good signal strength and very poor quality. Be sure you check the CCQ. You want the value as close to 100 as possible. Generally when your ping times get that bad, CCQ falls down below 20. Many factors affect CCQ, from interference to multi-path.

I have one RB532A running two nstreme links using polling. Connection tracking is off and traffic isn't too bad, around 500k-1MB running through both interfaces. But CPU usage seems to run around 94-99pct fairly constant. Currently it is running 2.9.50. CPU usage seems awfully high for just such low...

I understand the RSTP part. If there are multiple paths on the bridged network to the same device then you get a nasty bridging loop that will shut the network completely down.

I've actually wondered this myself. I would imagine it would work. Your signal power gets cut in half when you use a 2-way splitter (IFAIK).

I'm sure the cleanest thing to do is break down and bridge 2 radios, each on its own antanna.
