I have two PTP links using RB711GA-5HnD on each end. Using dual chain NV2 and both train up at 300/300 with roughly -56dBm signal strength running RoS 6.5.
Have worked flawless for 6+ months. During the last month or so, they have suddenly been prone to dropping to 6Mbs and staying there until I forcibly drop and re-establish the connection. Some times they will fluctuate between 6Mbs and 27Mbs, but they never go above 27Mbs until I either drop and re-establish the connection or reboot one of the units. They then are rock solid at 300/300 for about 24 to 36 hours before they again drop down. I have tried several different versions of RoS with no difference. CCQ is fine and changing frequencies doesn’t seem to make any difference.
I have tried using custom configured data rates and disallowing any MCS less than 4, but behavior remains the same.
Has anyone else had similar problems or have any suggestions?
Thanks
