I have an RB433 with R52 miniPCI and Grid Antenna. On client side, I have a deliberant (APC 2S-20). I've setup the client and get -64dBm of signal. But the problem is, sometimes (frequently) the log (RB433 side) tells me that the client was disconnected, and reassociating and the connected again. It can't be stable. Anyone can help me?

Sorry, my English is not good enough. And this is my first post here. I hope anyone can help.
Thank you, greeting from Indonesia.

What is the noise floor? As long as the difference between the signal and noise is 30dB or so on all chains your modulation should be good. You should be able to reference the require signal for each modulation.

However this is not all that there is to wireless. There are various factors that can cause your signal to fade including fog, rain, and even atmospheric conditions to name a few. It would be worth charting your signal and noise to watch the changes in relation to change. I've even heard of a link dropping when the water tower it was on was filled.

Solved... I just change the tx-power on the client side (deliberant) from 30dBi to 25dBi and all works fine. I thinks it just the problem on client side. When I reach out the limit (31dBi) it gets unstable. Thanks for help.
