Hi,

I'm having issues getting my Raspberry Pi 4 running Raspberry OS working with the TL-WR902AC. My broadband router has the IP address 192.168.1.1. The WR902AC has the IP address 192.168.0.1. 

All of my devices can connect to the WR902AC and access the Internet fine. However I get issues with my Pi. If my Pi connects to the broadband router, I can ping 8.8.8.8.

But if I connect to the WR902AC, I can't ping 8.8.8.8...

I have a feeling it's due to the routing table containing an entry for the broadban router as a gateway, but it should be hitting the WR902AC instead.

Anyone got any ideas how to get it working? Thanks!
