Does the performance of the links degrade when this happens (latency, bandwidth)? It’s odd as your transmit rates aren’t changing that much…maybe it’s just an issue with the drivers reading the card wrong?
we saw that on one of our routers the other day - exactly the same thing. Changed channels and all seemed to be ok. Noise floor was high when the problem occured (-75).
If I recall correctly bandwidth and latency didn’t seem to be effected. I was thinking the same thing regarding the drivers. I’m out of the office today so I won’t be able to test it again to confirm. When I get a chance to I’ll test it again to verify.
