New official firmware on the support site: Download for Archer BE800 | TP-Link

@Mark6ix You may have to delete everything from Home and redo it. You may have different IP addresses for everything with the new router.

@OgDiva2026-Tee Sometimes after a firmware update, it is good to do a factory reset and redo your network settings. Seems to fix any issues.

@John_B1702 I would ignore it. Look at the address of the sender and see if it is legit.

@Tw0-Turn_s You may have to remove the printer and add it back again as the IP has probably changed.

@Oboogie 10 Feet is pretty close, might be some radio interference from being that close.
