Frequent disconnections come from four places: the ISP line, the router itself (overheating, old firmware, failing power adapter), power dips, and local network problems such as IP conflicts. Check whether only Wi-Fi drops or the internet light on the ISP box goes off too. That one check tells you whether to call the ISP or fix your own network.
Key takeaways
- Check whether the ISP light drops too.
- Power dips reboot routers: put them on a UPS.
- Overheating routers in cabinets drop often.
- Old firmware causes random drops.
- IP conflicts drop single devices.
01Quick checks you can do first
- 01Watch the lightsIf the ISP's internet or LOS light goes off, the problem is the line. Call your ISP.
- 02Put it on a UPSEven a short dip reboots a router. A small UPS keeps it running.
- 03Give it airMove it out of cabinets and away from TVs and decoders.
- 04Update firmwareCheck the admin page or app for updates.
- 05Check one device or allIf only one device drops, it's that device or an IP conflict.
02What usually causes it
| Symptom | Likely cause | Fix |
|---|---|---|
| Internet light goes off | ISP line fault | Report to ISP with times |
| Router reboots in power dips | No backup power | Small UPS for router and ONT |
| Drops when hot afternoons | Overheating | Ventilate or replace |
| One device drops | IP conflict or device Wi-Fi | DHCP reservation, update device |
| Drops with many users | Consumer router overloaded | Business router or AP |
03When to call a technician
- It's a business and drops affect sales or POS.
- You have many users or CCTV on the same network.
- You need a backup internet line (failover).
- The ISP says the line is fine.

04Parts that fix it
05Frequently asked questions
Why does my internet drop every evening?
Peak-time congestion on the ISP side, or many devices at home. Test speed at different times and log drops.
Can I have two internet lines that switch automatically?
Yes. A dual-WAN router fails over to a second line (for example Safaricom fibre and Starlink) when one drops.
Does a mini UPS help?
Yes. Routers and ONTs use little power, so a small UPS keeps the internet up through most blackouts.
