Reply To: How much data does it take to run Uo?

With a bad router bandwidth might not be the only concern tho and keeping it busy with only one client sending/receiving packets all the time can probably interfere with other clients in the worst case.
In my experience number of wifi connected clients is what really affects the stability though, and since you’re wired that shouldn’t make any difference.
Do their connection issues go away right after they disconnect your PC? In that case I’d try another router, because there’s no chance it’s a bandwidth problem.
