How to narrow it down from power and cable to IP address and router. Every day this stays broken costs you more than the repair would. Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Check power, cable and link lights first. - One device offline: usually its cable, port or address. - Everything offline: switch, router, power or ISP. Quick answer When a networked device shows offline, work up from the physical layer: is it powered, is the cable and port good, does the switch show a link, and does the device still have the right IP address? Most offline devices come back after fixing power, a loose patch lead, an IP conflict or a router change.

Real products, live prices, in stock now ## Key takeaways - Check power, cable and link lights first. - One device offline: usually its cable, port or address. - Everything offline: switch, router, power or ISP. - Recent change? New router, power cut, storm? - Keep an address list to spot conflicts. ## Narrow it down | What's offline | Most likely | | --- | --- | | One device | Its power, cable, port or IP address | | Everything on one switch | That switch or its power | | Everything | Router, main switch, power or ISP | | Only remote access | Internet or router, not the device | | Wi-Fi devices only | Wi-Fi access point or signal | ## Safe checks 1. **Is it powered?**: Lights on the device? PoE? Adapter? 2. **Link lights**: Is the switch port lit for that device? 3. **Swap the patch lead**: At the rack, try a known-good lead or port 4. **Restart in order**: Router, then switches, then the device 5. **Check for changes**: New router, power cut, storm, recent work **Warning**: Don't open equipment or re-terminate cables yourself. Storm damage often affects several devices at once. ## When to call a professional Cable faults inside walls, IP conflicts, switch or router configuration and surge damage need a technician. See [network switch not working](https://qyvea.co.ke/network-switch-not-working-kenya) and [IP addressing basics](https://qyvea.co.ke/ip-addressing-basics-kenya). ## Frequently asked questions Why do devices go offline after a power cut? Equipment may not restart cleanly, may get new IP addresses, or may have been damaged by a surge. Why does my device keep dropping in and out? Common causes are a damaged cable or connector, an IP address conflict or a PoE budget problem. Can a bad cable look like a device fault? Yes. A cable can pass a basic link but still drop under load; it needs proper testing. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
