So bought the archer nx200 and planned on using unlimited sim from ee. Plugged it in, put sim in and if I want to play xbox ot has no latency. Change sim to my phone one and everything is fine. Use the unlimited sim in my phone as a hotspot and everything is fine. I don't understand why unlimited sim doesn't work in the router but works fine on my phone. Tried support who said engineering will get back to me but that was a week ago so gave up with them
