We had a problem with the link is flapping and down for more time even the signal is showing normal RSSI = -70 dbm to -85 dbm. If the link is down for long time. Then we need hard restart router multiple time after that only the link comes live, Kindly assist to get out from this, Bcoz we have a lot number routers with the same issue.
