I’ve got 35+ of the AR750, to be used to connect two PC’s via Ethernet and WiFi to the internet. They started out working on ver. 2.27, but are starting to drop their connections for hours or days. Resetting the network or resetting back to factory does not restore LAN connectivity. Unless we have a lot of bad hardware, the LAN switch has some serious issues.
If you get both devices connected, and then swap the cables between the Lan ports, it might work. If you switch back, neither will get a connection. Its almost like the port routing table never updates.
So that’s the problem, how can I help you fix this?
