Topic: Which Signal strength is which?

Ouch. -90 is a bad noise floor. What that means is at unit A there is more noise than at unit B, so the signal strength is worse at the A location. I'm sure if you look at the noise floor at B it will be somewhere around -100-110. -91 is the threshold on most cards. You should try to manage spectrum...

Using 2 sr cards is a recipe for destruction. It really does cause issues and can blow out the radios or 532s. If you need more than one 400mw card I would suggest using an amplifier and lower rated cards if it is within your budget.

You can use the dude to monitor the links, and to log what happens on all the routerboards. Also, you can get an ethernet ups that can sit on an ip and you can use it to reset equipment.

Why don't you assign out the customers /32s statically framed against radius? That plus PPPoE means even if the devices could see each other they are not particturally 'vulnerable' to broadcast packets.
