C35 Controller running 10.41.12.0006
Client: Lenovo A485, Windows 10Pro - Realtek 8822BE chipset
We have issues with some clients that have Realtek chipsets when they are on 5ghz and associated with the 3705 AP. They experience extremely high latency: ping times to the nearest switch on the network over 2 seconds. Also some clients are not always able to connect after being off the network for a while.
The clients when at a different site with newer APs(38xx,39xx)) do not have this problem. We'd like to get this solved without having to buy new APs because the 3705 is still supported.
Suspend laptop. Resume next day.
Windows unable to get a working connecton.
Ping time to switch: 1000-2500ms
Disassociate laptop from controller. Laptop does not connect again(Windows 10 doesn't bother trying to reconnect).
Force reconnection from client. Works.
Ping time to switch: 500-2800ms
Disassociate. Force reconnection.
Ping time to switch: 100-1000ms
Forcing laptop adapter to use 802.11b/g/n on 2.4ghz fixes problem.
Ping time to switch: <5ms
