I have a problem that occurs with Mikrotik R52n-M radios I bought. After a period of time, the radios go silent and all connections drop. I have to reboot and then I can see the SSIDs and connect with my laptops and smartphones again but after another period of time, the radios go silent again.
I'm using x86 v6.11 on two different model computers for two routers. I have two brand new Mikrotik R52n-M radios and both do the same thing. I use minPCI to PCI adapters. The radios experience the same problem on both routers. One router is configured with two VAPs and the other doesn't have any VAPs.
All other radio versions I have work with no issues. I used them on the same miniPCI to PCI adapters and routers.
I wanted to upgrade to a radio that supports 802.11n. The Mikrotik R52n-M radios support 802.11b/g/n.
