So, we are experiencing some issues in our LAN where users who are signed into their RDP session are experiencing some serious latency issues. I checked the ping utility for some of the devices and they are having latency upwards of 50 - 100ms. The Thin Clients are all wireless, but can be wired. I tested them with an ethernet connection and they are very stable with very little latency. However, we had all of our users on their thin clients and they were working fine on wireless for a couple months. Randomly they stared having this issue and we do not understand why it's doing what it is. I don't see that the RF Spectrum is being flooded. The issue is resolved when the computer is plugged into ethernet. The thing is, it's only happening on the South and West sides of our building. The north side is fine and they're not experiencing any latency issues.
The minimum bitrate for the basic indoor profile we are using is 18. Client balancing is turned off and channel width is set to 80MHz. This is also making use of 802.11ax. We do have some QoS settings in place to prioritize RDP traffic and give it unlimited bandwidth per client. As for the noise, there is barely any noise in the RF Spectrum. It has been reading less than 20 - 30 per day.
