The latest September 2026 insights from Ookla’s Speedtest Intelligence point to a Nigerian broadband market increasingly shaped by a combination of fibre, mobile and satellite connectivity. The data shows major improvements in fixed broadband speeds, a strong rebound in mobile connectivity led by 4G, expanding 5G availability and growing competition from satellite broadband.
However, the figures also expose a paradox: Nigeria’s networks are becoming faster, but consumer satisfaction is declining, while the country’s expensive 5G infrastructure remains significantly underutilised.
Fibre Emerges as Nigeria’s Broadband Growth Engine
Fixed broadband has become a major bright spot in Nigeria’s connectivity evolution, with fibre deployments driving substantial improvements in both download and upload performance.
According to Ookla’s data, median fixed broadband download speeds increased from 13.50 Mbps in 2023 to 34.47 Mbps in the first half of 2026.
Upload performance also improved considerably, rising from 11.00 Mbps to 25.17 Mbps over the same period.
The improvement extends beyond raw speed. Median fixed broadband latency declined from 47.9 milliseconds to 35.8 milliseconds, improving the responsiveness of applications that depend on low-latency connections, including cloud services, video conferencing and online gaming.
The growth in fibre subscriptions has been equally striking.
Nigeria’s Fibre-to-the-X (FTTX) subscriber base increased by about 29 per cent in a single quarter, climbing from 241,750 connections in Q1 2026 to 319,735 in Q2 2026.
Over an 18-month period, fibre subscriptions grew more than 3.8-fold, reaching nearly 320,000 connections by June 2026.
That expansion helped push median fixed download speeds to around 34.83 Mbps, while upload speeds reached 25.32 Mbps in Q2 2026, according to the supplied Ookla data.
5G Coverage Expands, But Adoption Remains Low
Nigeria’s 5G story presents a very different picture.
While operators have continued expanding their 5G footprints, the technology accounted for only 4.6 per cent of mobile connections in the latest data.
At the same time, 5G availability has expanded substantially. The proportion of scanned locations with 5G coverage increased from 11.3 per cent in 2023 to 28.9 per cent in 2026.
Ookla’s separate 5G Availability measure also increased from 6.9 per cent in 2023 to 18.8 per cent in 2026 year-to-date, indicating that users with 5G-capable devices are spending more time connected to 5G networks.
Yet broader adoption has not kept pace with network expansion.
The result is a growing gap between 5G infrastructure availability and actual consumer usage.
5G Speeds Fall as Network Usage Grows
One of the most notable findings in the Ookla data is the decline in median 5G download speeds.
Median 5G download speed fell from about 329 Mbps at the technology’s early launch period to 155 Mbps in 2026.
The supplied analysis links the decline to increasing network congestion on shared spectrum as more users occupy the available bands, alongside the challenges of optimising an expanding 5G network.
The decline does not necessarily mean that 5G infrastructure is contracting. Rather, it illustrates the difference between headline network capability and the speeds users experience as networks scale and traffic increases.
Meanwhile, overall mobile internet performance has improved. Median mobile download speeds across technologies increased from 18.94 Mbps in 2022 to 26.22 Mbps in 2026.
That improvement reflects the continuing importance of 4G, which has become Nigeria’s dominant mobile technology.
4G Remains the Workhorse of Nigeria’s Mobile Market
Following the extensive SIM registration clean-up exercise, Nigeria’s active mobile lines recovered to approximately 192 million by mid-2026, according to the supplied data.
4G now accounts for 54.3 per cent of the subscriber base, making it the dominant mobile technology.
This gives Nigeria a two-speed mobile transition: 4G continues to provide the broad mass-market foundation for mobile internet, while 5G expands as a higher-capacity technology but remains constrained by device affordability, data costs and coverage limitations.
The economics of 5G devices are particularly important in a market where inflation has weakened consumers’ purchasing power.
Ookla’s analysis indicates that the cost of 5G-capable smartphones and higher-tier data packages remains a significant barrier to adoption. Some consumers with 5G-capable devices also continue to use 4G because of its substantially wider coverage footprint.
Starlink Adds a New Layer of Competition
Nigeria’s broadband market is also becoming more technologically diverse as satellite connectivity expands.
Starlink had reached 98,642 subscribers in Nigeria by June 2026, making the country its largest African market, according to the supplied Ookla data.
Satellite broadband offers an alternative for consumers and businesses in locations where terrestrial infrastructure remains inadequate or difficult to deploy.
However, the competitive picture is not one-sided.
The supplied Ookla analysis indicates that traditional fixed internet service providers are steadily narrowing the download-speed gap with satellite broadband while maintaining advantages in upload performance and latency.
The development means Nigeria’s broadband market is increasingly moving towards a multi-technology environment in which fibre, mobile networks and satellite services address different connectivity needs.
Nigeria’s Urban-Rural Digital Divide Persists
Despite improvements in overall network performance, the digital divide between urban and rural communities remains visible.
Ookla’s data shows urban median mobile download speeds fluctuating between approximately 17 Mbps and 24 Mbps, compared with 14 Mbps to 21 Mbps in rural areas.
The difference may appear narrower than the historical connectivity gap, but it remains significant because rural communities increasingly depend on digital connectivity for access to financial services, education, healthcare, agriculture and online commerce.
The challenge is therefore not simply getting a signal to underserved communities. It is ensuring that those communities receive connectivity that is fast, reliable and affordable enough to support meaningful participation in the digital economy.
101,000km Fibre Backbone Sets Stage for Next Expansion
Nigeria’s wider digital infrastructure programme is also expanding.
The supplied analysis states that approximately 101,000 kilometres of fibre cables have been deployed, with the country preparing for another 90,000-kilometre fibre rollout backed by a US$500 million World Bank project.
The next phase is expected to further strengthen broadband availability and provide additional capacity for Nigeria’s expanding digital economy.
The fibre push is particularly significant because increased capacity is becoming essential as cloud computing, artificial intelligence, digital financial services, streaming, e-learning and enterprise applications generate greater demand for high-quality connectivity.
Better Networks, Lower Consumer Satisfaction
Perhaps the most revealing aspect of the Ookla data is the apparent disconnect between infrastructure improvements and how consumers perceive their internet services.
Consumer rating scores for internet service providers declined from 3.4 in 2022 to 3.0 in 2026, while the Net Promoter Score (NPS)—a measure of customers’ willingness to recommend their provider—fell from -15.6 to -34.3.
Ookla attributed part of the decline to increased customer frustration following higher mobile tariffs.
This suggests that network investment alone does not automatically translate into higher customer satisfaction.
For consumers, the practical experience of connectivity is shaped by a combination of speed, reliability, coverage, latency, affordability and the amount of usable data available for the price paid.
Wi-Fi and Indoor Connectivity Remain Gaps
The connectivity challenge also extends beyond outdoor mobile coverage and national fibre infrastructure.
Ookla’s analysis points to continuing weaknesses in indoor connectivity, with implications for small businesses, homes and services such as telemedicine.
The issue highlights the importance of complementary connectivity infrastructure, including Wi-Fi, as Nigeria expands its digital economy.
The supplied analysis argues that regulatory intervention around spectrum could help the country move more rapidly towards next-generation technologies, including Wi-Fi 7, rather than remaining constrained by legacy infrastructure limitations.
Nigeria’s 5G Journey Began With MTN and Mafab
Nigeria’s 5G commercial journey began after MTN Nigeria and Mafab Communications emerged as winners of the 3.5GHz spectrum auction in December 2021.
Each operator paid US$273.6 million for the spectrum, while MTN also paid a US$15.9 million assignment fee, according to the supplied material.
MTN subsequently expanded its 5G network across major Nigerian cities, while Mafab’s rollout initially focused on Lagos and Abuja.
Airtel Nigeria entered the 5G market in January 2023 after securing a 100MHz 5G licence for US$316.7 million, according to the supplied information.
The subsequent expansion of 5G coverage demonstrates significant infrastructure investment. But the latest Ookla measurements show that expanding the footprint and achieving mass-market adoption are two different challenges.
Nigeria Moves Towards a Multi-Technology Broadband Market
Taken together, the Ookla findings point to a Nigerian connectivity market that is no longer defined by a single dominant technology.
Fibre is rapidly improving fixed broadband performance. 4G remains the backbone of mass-market mobile internet. 5G is expanding its footprint but has yet to achieve widespread adoption. Satellite broadband is adding another option, particularly for underserved locations.
The next phase of Nigeria’s digital transformation will therefore depend not only on deploying more infrastructure, but on closing the gap between network availability, actual usage, affordability and customer experience.
The fibre boom demonstrates what sustained infrastructure investment can achieve. The 5G experience, meanwhile, shows that coverage expansion alone does not guarantee mass adoption.
For Nigeria’s digital economy, the central challenge is increasingly shifting from simply connecting more people to ensuring that the connectivity they receive is fast enough, affordable enough and reliable enough to support productive digital participation.
