Collapse of Cambium Networks Should Come as a Warning Sign to Competitors and Customers Alike

After several years of strategic errors, mismanagement, and reputation-shattering scandals, on September 14, 2026, enterprise Wi-Fi equipment vendor Cambium Networks finally collapsed and entered administration. Airspan quickly emerged to acquire several key fixed wireless Point-to-Multipoint (PtMP) product lines from Cambium’s portfolio, while the remainder of Cambium’s product lines, intellectual property, and contracts were acquired by Univastu India Limited. While the news did not come as a surprise to those familiar with Cambium Networks’ recent turmoil, the demise of one of the industry’s most recognizable names not only presents a major challenge for the company’s existing customers’, but will also bring significant disruption to the industry. This ABI Insight looks back at Cambium’s recent history to understand the factors behind its collapse, and analyzes the implications of Cambium’s downfall for the broader enterprise Wi-Fi market.

Cambium Networks began the decade in a strong position. By 4Q 2019 Cambium Networks had enjoyed 23 consecutive quarters of Year-over-Year (YoY) revenue growth, and although the unexpected shock of the COVID-19 lockdowns did bring an end to this streak in 1Q 2020, a rebound in the latter half of the year enabled the company to still achieve a 4% revenue jump YoY for 2020. This success during the early days of the COVID-19 pandemic contrasts with the 2.5% and 1.0% YoY revenue declines experienced by Cisco and HPE Aruba in 2020, respectively. Cambium’s stellar financial performance continued into 2021, when its revenue climbed 20.6% YoY. On the surface, Cambium appeared like a well-managed company with a strong outlook, but under the hood, the reality was that this growth was built on shaky foundations and was ultimately unsustainable.

Cambium’s 2021 success was primarily fueled by aggressive purchases from customers and channel partners bringing forward orders and stockpiling hardware in fear of supply constraints. Cambium also benefitted from the logistical and supply issues that its competitors were facing at the time (Cisco’s backlog peaked at US$15.9 billion in 2022), as Cambium’s competitors’ inability to fulfill orders drove a small but significant segment of their customer bases into Cambium’s own hands. This was inherently unsustainable, and when component availability improved and supply-related issues normalized in 2022, inflated levels of demand for Cambium’s equipment fell off dramatically. By early 2022, Cambium’s distributors and resellers also had their inventories fully stocked, meaning that for the rest of the year, it was focusing on offloading its accumulated products instead of placing fresh orders. This sharp contraction in orders resulted in an 11.6% decrease in YoY revenue in 2022.

While the changing macro environment was out of Cambium’s control, the numerous strategic blunders, which ultimately prevented Cambium from recovering, were of the company’s own making. The first of these was a failure to accurately forecast future demand. Believing that heightened levels of demand would continue for the long term, throughout 2021 and 2022 Cambium built up a vast inventory of Wi-Fi 6E Access Points (APs), which represented cutting-edge technology in the industry at the time. But due to the short product cycles in the modern enterprise Wi-Fi market, coupled with the relatively niche market for Wi-Fi 6E (due to limited 6 Gigahertz (GHz) access outside of the United States), these Wi-Fi 6E APs quickly became obsolete. Inventories were already full at Cambium’s traditional distribution channels, so Cambium was unable to offload its massive Wi-Fi 6E stockpile, much of which was a write-down, causing a significant drag on Cambium’s balance sheet.

Then, there was Cambium’s inability to fully take advantage of the assets acquired through its 2019 purchase of Xirrus’ Wi-Fi portfolio and cloud-services business from Riverbed. Cambium aimed to leverage Xirrus’ legacy to expand beyond its traditional mid-market customer base and into the wider large enterprise and campus markets. Yet, Cambium struggled to exploit Xirrus’ existing enterprise sales channels, in part because a full integration of Cambium’s stack with Xirrus’ didn’t arrive until 2022, too late to capitalize on the 2021 demand boom. Cambium’s strategic direction during this period was also unclear, and the company never committed to prioritizing any specific customer segment. While Cambium’s Research & Development (R&D) budget was dwarfed by many of its competitors, it still aimed to develop industry-leading platforms for an ever-expanding range of customers, which grew to span from industrial sites and mines to large enterprise and Wireless Internet Service Providers (WISPs).

As the challenges mounted for Cambium Networks, its financial reporting began to falter, and in August 2025, the company was issued a compliance warning from Nasdaq due missing financial filings, including the 2024 Form 10-K and quarterly Form 10-Q reports. In the same month, Cambium Networks admitted that its financial reports stretching back to 2022 had been unreliable due to accounting errors, and that they needed to be restated. A Nasdaq hearing panel met in December 2025 to discuss how to handle Cambium’s listing on the stock market, and it was concluded that Cambium could conditionally remain on the Nasdaq on the promise that it would resolve its filing deficiencies and meet the minimum-bid-price requirement. Yet in March, the panel determined that these conditions had not been met, and suspended trading for Cambium. This delisting decision was affirmed in August 2026. Cambium’s descent thereafter was rapid, climaxing in its eventual collapse in September and the selling of its remaining assets in October.

The largest immediate impact of Cambium’s collapse will be felt by organizations currently relying upon Cambium’s hardware and its management platform cnMaestro. Thankfully, both Airspan and Univastu have committed to maintaining the operation of cnMaestro, helping to avert a sudden shutdown of Cambium’s management layer. However, the longer-term future of the platform is uncertain, and it’s not clear how troubleshooting or patching will be handled, or if we will see subsequent advancements to the platform as users would expect. Whether or not we will see future hardware releases from Cambium is also ambiguous, and the future strategic focus of the new company remains vague. Will Cambium under Univastu India Limited prioritize the needs of the Indian market (historically, a major market for Cambium)? Could it retreat from certain verticals to concentrate resources in select target areas? Cambium hazing future prospects will undoubtedly dissuade a large portion of potential new customers from choosing Cambium and, in turn, weak future customer (and revenue) growth may also constrain Univastu and Airspan’s ability to support Cambium going forward.

Given the unclear future of Cambium under its new owners, existing customers are advised to reassess their network and Cambium’s role in it. This does not mean an immediate and hasty wholesale rip-and-replace of Cambium equipment, but we do recommend that concerned users begin implementing a phased migration to a more reliable platform. The first step of this is to identify mission-critical assets reliant on Cambium equipment, and ensure that they at least have redundant connectivity. Those considering becoming potential new buyers of Cambium products should ensure that an exhaustive assessment of product cost across the full lifecycle is conducted, and make sure that you are prepared for any future removal of support.

Cambium’s contraction will naturally create a vacuum in the market that its peers will fight over. New opportunities in the cost-sensitive segment will likely be contested by companies like Ubiquiti and Omada (TP-Link’s enterprise line), whereas Cisco, HPE, and Extreme Networks will try to capture market share in the large enterprise and campus segments. As for fixed wireless opportunities, Airspan undoubtedly wishes to retain Cambium’s market-leading position in this space, but it is likely to lose market share to Tarana, Mimosa, RADWIN, and Ubiquiti.

More broadly, Cambium’s difficulties reveal a series of valuable lessons to all vendors in the enterprise Wi-Fi industry. They demonstrate the importance of understanding the capacity of channel partners and of accurately forecasting future demand. They highlight the importance of having solid backup plans should daring strategic bets backfile. They also provide a cautionary example of the risks involved in overextending and trying to address more market segments than a vendor’s resources allow.
