My Wi‑Fi is not working—what do I do?
First establish whether all devices are offline or only one device/room. Check router/ONT power and lights, then test one device close to the main router.
TriageIs the broadband down or is it just my Wi‑Fi?
A wired test at the main router separates the incoming service from the wireless layer. If wired works but Wi‑Fi does not, focus on coverage, interference or the client.
TriageOnly one phone or laptop won’t connect—why?
If other devices work, the broadband and router are probably live; forget and rejoin the network, verify password, update/restart the device and check it is not paused or blocked.
TriageSome websites work but others do not.
This can be DNS, VPN, filtering, IPv6 or the destination—not necessarily weak Wi‑Fi. Compare another device/browser, disable VPN temporarily and test a known site.
TriageThe Wi‑Fi says connected but there is no internet.
The device has joined the local wireless network but the router may lack a working internet session, DNS may be failing, or access may be paused.
