Low speed with TP-Link Deco X50-5G LTE WLAN Router
I recently bought a TP-Link Deco X50-5G(1.0) router to use with a SIM card. I am getting low speed (about 35 Mbps) compared to what I get on a 5G connection on my phone (150 Mbps) in the same location. I am also only getting 4G+ while other devices get 5G in the same area. Can anyone help with any troubleshooting steps to come close to the speed I am getting on my phone?
Additionally, when I login through the web browser then I see ISP's DNS while in the Deco app I see the Cloudflare DNS. I will appreciate any help to ensure that these two are consistent.
