I recently bought a TP-Link Archer AX10 AX1500 wifi router. It is connected to my modem. Both the modem and the router act as dhcp servers but on different subnets, so the modem (192.168.1.254) only allocates 192.168.1.1 to the wan port of the router and the router allocates 192.168.0.x ip address to all of my connected devices.

When I connect to the router with ethernet, everything works fine with great speeds.

When I connect through WiFi, there is no internet on my PC running a PCiE Qualcomm Atheros AR938x Wireless Network Adapter. The adapter connects to the WiFi but I can't even ping the modem.

Any thoughts? It's got me beat.
