Hi thank you for replying to my post, I’ve managed to enable upnp and the ping isn’t too bad now. My only issue now is that whilst playing Xbox literally within 20 minutes or half way through the game my whole router will reboot and disconnect. Do I have to adjust any other settings? There’s port forwarding, dmz etc..
Clearly, something is badly wrong with your setup. The router should not reboot.
I don't have 5G coverage, but have been using Three 4G for years. The latency is a bit terrible. usually more than 30ms, sometimes more than 100ms. The connection stays rock solid - I only use Huawei modem/routers partly because they seem to work better than other brands.
Three speeds vary a lot depending on which cell you are linked to and the time of day. Blisteringly fast at 4am.
It does matter which apn you use, though. three.co.uk is iffy. Far better to use 3internet which also gives you a routeable IP, though not a fixed ip.
