I’m trying to link two RB Groove A-52HPn and I’m having this problem of connection.
I configured one Radio as a WISP AP and the another one like a CPE.
I noticed that when I disable the encryption, the link is stablished succesfully.
What it can be?

I have the same trouble with 2 metal 2SHPn.
I have an encryption too.

Did you manage to get a stable link ? I got my phone connect on the AP and I have no issues with it
