My access points on the network keeps freezing all the time. Initially i have a single access point (NANO STATION5 RADIO) on which other(NANO STATION5 RADIO)used as base stations connected. Everything was working fine. But after sometime, the NANO STATIONS RADIOS keeps freezing such that i have to restart the radios before they will work again then go off again. Now i have three separate point to point connections yet i still keep having the same issue with all the radios freezing. I have scanned the network for virus, none was found. Please kindly help on what to do next.
