IT help needed

[maks]

wifi loses internet, does it lose LAN? is your WAP actually a router? are they trying to use it as a gateway somehow? is it running a DHCP server? has anything changed in the clients routing tables? there's about a thousand questions I can ask but first and foremost post the results of "route print" before and after

The routers wifi loses internet, that is all. The AP is an access point, not a router. Network goes modem > router > switch > AP. It should be pretty simple to connect right? Just plug it inti ghe network. I got the AP working fine but the router in a separate office loses its wifi internet (but hardlines work)

AP is not a DHCP server, router is an old Netgear with factory settings except for SSID and password. AP also has factory settings
