This Asus RT-AX86U Wifi 6 router is in good shape and is plenty fast for gaming on a 1 Gbit fiber connection. It's been updated to firmware version 3.0.0.4.388_24401 and factory reset as instructed (the setup wizard will start when connected, and it needs to be configured).

Wireless coverage is great, and this model is an award-winning router.

The antennas are a bit loose when screwing them in, but they've always been this way. There are 4x 1Gbit LAN ports + 1x 2.5Gbit LAN/WAN port (supports jumbo packets) + 1x 1Gbit WAN port.
