Asus AX86U and T-mobile 5G Gateway
Hello. I recently signed up for T-Mobile home internet with the 5G Gateway (made by Nokia). I am using my ASUS AX86U router in conjunction with the Gateway (in Wireless Router mode). The router conne...
I thought I would report back since I was able to find a solution on another forum. Since I am not a network guy, I don't even really know what this means, but I thought I would post it in case someone else runs into this issue. I lowered the MTU WAN setting on my router from 1500 to 1420 (the T-Mobile Gateway maxes out at 1420, per my other sources). My stock router firmware did not have this setting, so I flashed the Merlin firmware to access it on my WAN settings page. ¡Gracias!

Yeah - the AX86U is connected via ethernet to the modem/gateway. I really don't want to use AP Mode because I am also using a PiHole on my LAN, and there is no way to set a manual DNS on the modem/gateway (although I guess I could set the DNS on the router). I also tried AP mode, and I couldn't seem to connect to my Plex server from my other LAN devices.
My PC, which is wired directly to the router, works fine - so the hand-off from the router to the modem/gateway is working. Does it really handle the hand-off differently between WiFi and wired?
