WiFi Problems with G4AR Gateway

Hola,

I have a G4AR as part of a Small Business Internet service.  Recently during a thunderstorm, the Wifi stopped working.  The router and 5G connectivity were not impacted.  Luckily most of my devices are hardwired and continued to work.

After the storm, some of the wireless devices reconnected and worked correctly while others can connect to the G4AR but are unable to communicate with the Internet.  

Has anyone seen this type of issue before?

Gracias
