This morning I have an unusually high amount of APs reporting low goodput on 5GHz. These APs shows "0 - 6 Mbps" for more than 90% of the traffic TO the client. Frame rates FROM the client are just fine, mostly 108+ Mbps. Only a few APs' noise floor is below -85, channel utilization is very low, and there aren't a high amount of frame drops to the client. Any suggestions on troubleshooting low frame rates to the client?
