WiFi is interrupting my LAN environment.

Recently i joined a small company where we have couple of servers (ERP, DB, mail & AD) a fortinet for VPN and untangle firewall to filter all the incoming/outgoing traffic. we have about 10 locations connected to HQ. 7 locations are connected via antenna. and other location via fortinet VPN. In our office we have 3 WiFi APs.This locations are pretty close to our HQ so the manager thought it would be a best option for connectivity. and it has been made 8+ years before(pretty old, right?).

yesterday suddenly all connectivity gone (internet & LAN). none of our locations wasn't being able to open ERP. so as a first thing i pinged my dns and gateway but they were dead. lots of thing has been done but still connectivity wasnt recovering.

so after a while i restarted the fortinet and wifi APs. it was just my random click not any intellectual thing was involved. so here you go, the LAN & internet starts working. i was like "say what !!!!".

so any idea what went wrong? this is my first post here so forgive me for any mistake.
