First Steps Before You Call

1
Check whether it is just you
If a neighbour on the same Optimum service is also down, it is an area fault rather than your equipment, and the fix is different.
2
Power cycle the Optimum Smart Router
Unplug the Optimum Smart Router at the mains, wait thirty seconds, plug it back in, then give it two to three minutes to fully re-register before testing again.
3
Test wired against wireless
If a device connected by cable is fine but Wi-Fi is not, the fault is the wireless side rather than the incoming line — that changes what gets fixed.
4
Note what the lights are doing
The light pattern on the Optimum Smart Router tells a specialist a lot. Have it in front of you when you call.
Common Faults

Service outage in your area

Optimum Smart Router restart

Working through a proper power cycle of the Optimum Smart Router in the correct sequence so the connection re-registers.

🐌

Slow speeds

Isolating whether the slowdown is the line, the Wi-Fi, or one device, before anyone books an engineer.

A charge you did not expect
