My internet is down – first step?
Power-cycle the router and test via Ethernet.
If mobile data works, check your provider’s app or status page for internet outages.
Wi-Fi is weak – can I fix it myself?
Often, yes — move the router higher/central, avoid metal cabinets, and split 2.4 GHz and 5 GHz.
Consider a mesh for larger flats.
When should I escalate to support?
If Ethernet is down, LOS light blinks, or outages persist.
Provide customer number, device MAC/serial, and times of failure.
