If your MTN FibreX has felt unreliable lately, it is not your router and it is not your imagination. In Lagos, FibreX subscribers had outages on 23 of the 31 days in July 2026, according to reporting by Moneycentral. That is not a bad week — that is most of a month.

The actual cause: Nigeria is cutting its own fibre

This is not an MTN-specific failure. The Nigerian Communications Commission recorded over 5,000 fibre-optic cable cuts nationwide in the first half of 2026 alone — and more than 9,200 across 2025, per ITEdgeNews. Roughly four out of five of those cuts trace back to uncoordinated road construction and civil works — a contractor digging a trench for something unrelated and severing the cable underneath, with vandalism and extortion attempts making up most of the rest.

MTN's own CEO has said as much publicly: fibre cuts, site vandalism and power theft are actively undermining network quality across the country, not just in one city. This is a national infrastructure problem being felt, one household at a time, as "why is my FibreX down again."

Why this matters more than a normal outage

FibreX runs on a single physical cable into your building. When the trench carrying that cable gets cut three streets away, every subscriber on that route goes down at once — there is no rerouting around a severed glass fibre the way there sometimes is with a mobile signal. Enterprise and remote-work subscribers paying up to ₦200,000 a month for guaranteed uptime have been among the loudest to complain, because for them a cut fibre is a cancelled workday.

What actually helps: a connection that fails differently

You cannot fix a road contractor cutting a cable three streets away, and neither can MTN, instantly. What you can do is stop having only one physical path into your house. A 5G outdoor unit (ODU) picks up the mobile network wirelessly — no trench, no shared cable route with your FibreX line. When a digger takes out the fibre on your street, a wireless signal from a cell tower is unaffected by it.

To be honest about the limits: an ODU is not immune to everything. It shares failure modes with the mobile network generally — mast congestion in the evening, or a power cut at the cell site itself. It will not save you if your entire area loses both fibre and mobile coverage at once. But "different failure point" is still real protection, and it is the practical answer available today, not a promise that outages stop.

This is why we would not tell a FibreX subscriber to switch away from FibreX — when it works, it is faster and has no data cap. The honest advice is to keep FibreX as the primary line and add an ODU as the backup that picks up the moment fibre goes down, rather than sitting offline until a repair crew reaches your street.

Picking Airtel for the backup rather than MTN is deliberate if your FibreX is MTN: the outage that takes down MTN's fibre in your street has no reason to touch Airtel's mast.

Questions people ask

Is this an MTN-only problem?
No — the underlying fibre-cut crisis hits every operator's cable in the ground. MTN gets the most attention because FibreX is the best-known consumer fibre brand, but Airtel and others report the same construction-damage pattern.

Will an ODU definitely stay up when FibreX is down?
Usually, because it is a different physical path. Not always — a mast can have its own outage, and evening congestion is real. It is meaningfully more resilient, not bulletproof.

Should I cancel FibreX and just use an ODU?
Not on the numbers most people see — FibreX has no data cap and is faster when it is up. Keep it as the primary and add wireless as the backup, not the other way around.

Is renewing MTN FibreX still worth it despite the outages?
That is genuinely your call to make with the numbers above, not ours to make for you. What we can do is make both renewals fast and refund automatically if either fails — see our FibreX renewal guide.
