Wireless routers

No I did not, because to do this, I will have to run a network wire from Desktop to Main router on floor. Anyway the problem is not severe on Desktop. Browsing & download / upload are very good. Regarding piaware in VM of Desktop (Receiver 4), I hardly get one or two notices per day as you can see below.

 

The problem is severe on Receiver 5. It is a RasPI Model 4. This RPi is located near main router, and connects to main router on WiFi directly, bypassing the Sub-router. Strangely this one is the worst in terms of piaware UDP issue. Please see below:
