Before getting too involved with troubleshooting:
- Ensure all physical connections are secure.
- Someone could have accidentally:
- Kicked the router or modem’s power cable
- Pulled an Ethernet cable out of a socket
After these checks:
- Bypass your personal Wi-Fi router
- Plug the cable from your PST device (depending on what PST service you have) directly into a laptop or desktop computer that has an RJ-45 Ethernet cable port.
Here is a list of services PST offers and the devices you may be dealing with:
Fiber Service – Calix Optical Network Terminal (ONT)
Coax Service – Arris Cable Modem
Ubiquiti Wireless Service – Ubiquiti Power-Over-Ethernet Device (POE)
