Cambium’s collapse shows what vendor risk looks like when it becomes reality: uncertain cloud management, stranded equipment and difficult migration decisions for MDU operators, while forcing MSPs and property owners to rethink technology dependency.
The weekend Cambium ran out of road. On Friday (September 11), Cambium Networks cut 260 positions, roughly 54 percent of its global workforce, with no severance for those affected. On Saturday, staff received an email from the CEO explaining that cash had run out, that efforts to sell some or all of the business had failed, and that the company would be handed to administrators in the UK. A second email followed with notices of immediate redundancy, and access to corporate email and Teams was cut shortly afterward.
On Monday (September 14), Cambium Networks Ltd, the UK entity that carries much of the group, formally entered administration in the High Court of England and Wales, with RSM UK Restructuring Advisory appointed to sell what assets and business lines it can. The company expects the remaining entities in that group to be wound up through local processes.
The account above of how the weekend unfolded comes from a public LinkedIn post by Carl Jefferys, until Friday regional sales manager at the firm for enterprises in Australia and New Zealand. Jefferys is now directing partners and customers to a personal email address because the corporate one no longer works. Most of the enterprise business – including licensing, support, procurement, and sales – has been let go. Word in the channel is that the fixed wireless business, excluding ePMP, may have been sold or is in the process of being sold. It remains unclear whether that transaction includes cnMaestro, the cloud management platform every Cambium Wi-Fi deployment depends on.
Two days before the layoffs, Cambium was still announcing products. The MarketApps Hub, a platform for building automation apps on top of cnMaestro X, was unveiled on September 9. That timing tells you how little warning the market received. It was not really a surprise in itself – only the scale of the company’s reversal.
Maravedis flagged the risk. In the 2026 Market Rate Connectivity Report, Cambium received a MDU rating from Maravedis as a ‘rising challenger’ with an ‘elevated execution risk’. The company had not filed audited financials since the end of 2024. It lost its CFO in September 2025, and was carrying a market capitalization near $40 million against roughly $170 million in trailing revenue. It received a formal written notice in October 2025 from the Nasdaq listing qualifications department (a ‘staff determination’ letter) that it had failed to meet Nasdaq’s listing standards.
Nasdaq delisted the stock in March 2026. Its last annual report carried a going concern warning citing covenant breaches and tight liquidity.
Our assessment at the time was direct: MSPs and property owners will not standardize on a vendor they perceive as at risk of disappearing, and the first item on Cambium’s strategic to-do list was to resolve its financial and listing uncertainty decisively. We also noted that a strategic buyer could redirect R&D away from multifamily. What no one in the industry expected, including the people inside the company, was that the buyer search would fail outright and the company would stop trading over a weekend. As Jefferys puts it, everyone had been waiting for an email about an acquisition, not this. He does not spare the executive team, calling the episode a display of incompetence and disrespect toward end users, channel partners, suppliers, and staff.
The frustrating part is that the product story was working. Cambium had built a credible price-performance alternative to RUCKUS in the MDU market. The ONE Network portfolio combined Wi-Fi, switching, GPON, fixed wireless backhaul, SD-WAN, and Starlink failover under a single console – which no other MDU-focused vendor could match. Wi-Fi 7 shipments grew more than 75 percent in the first half of 2025. Discernity publicly endorsed the X7-53X on price-performance grounds. Telecom consultants advising property owners had begun including Cambium in competitive evaluations as routine. The engineering was sound. The balance sheet was not.
MSPs running Cambium
Cambium reported roughly 2,000 managed properties across MDU and hospitality, with on-premises and cloud-managed devices numbering in the millions globally. In US multifamily, the exposure runs through the MSP layer. Of the 10 managed service providers profiled in a Maravedis 2026 report, three run Cambium equipment in the field. Discernity, with about 12,000 units under management in the Louisville area, is the most concentrated case.
The company selected Cambium as its primary vendor for both switches and access points after a formal evaluation against RUCKUS, then deliberately chose to double down rather than remain a generalist, with the stated goal of becoming the go-to Cambium expert other MSPs call for troubleshooting. Its operational automation, including “last gasp” power outage detection, runs through Cambium switches.
Maravedis noted vendor concentration risk in our Discernity profile earlier this year. That risk has now materialized in the worst possible form – although the depth of Discernity’s Cambium expertise also puts it in a better position than most to run an on-prem cnMaestro instance and keep its properties stable while it plans a transition.
Elauwit Connection, the publicly traded MSP with roughly 85,000 units, runs Cambium alongside RUCKUS and Cisco Meraki, with Wi-Fi 6 as its standard and Wi-Fi 6E in production. Smartaira, with about 110,000 passings, is vendor-agnostic and also runs Cambium alongside RUCKUS and Meraki, and was already evaluating EdgeCore and TP-Link before this weekend. Both have somewhere to turn, but our research does not break down what share of their installed base sits on Cambium. Any property currently on Cambium hardware faces the same operational questions as everyone else.
The remaining seven profiled MSPs – Allbridge, Zentro, Mereo Networks, Gigstreem, Aerwave, Dojo Networks, and Pavlov Media – either standardize on other vendors or do not disclose their equipment, so their direct exposure appears limited. Beyond the profiled group, however, a long tail of regional operators, hospitality integrators, senior living communities, and outdoor hospitality properties chose Cambium precisely because it delivered enterprise capability at mid-market prices.
Those smaller operators, with less engineering depth and no multi-vendor fallback, are likely to be hit hardest.
The cnMaestro problem
The immediate question every Cambium customer is asking is what happens to cnMaestro. The honest answer from inside the company is that nobody knows. The service is running. The people who maintain it are gone.
Jefferys’ practical advice is to download the on-prem version and manually migrate devices to cnMaestro Essentials. That keeps networks manageable, but Essentials has a reduced feature set compared with cnMaestro X. And there is a catch: migrating cnMaestro X licenses requires action on Cambium’s side, and no one at Cambium is left to do it. Customers on X subscriptions are in limbo until the administrators, a buyer, or someone else clarifies who owns the platform and who must keep it alive.
This is the episode’s structural lesson, and it extends well beyond Cambium. A cloud-managed networking platform is only as durable as the company that operates it. When the hardware is fine, but the control plane depends on a vendor’s cloud, a vendor’s licensing servers, and a vendor’s engineers, the failure of the vendor becomes the failure of your network. Jefferys raises the question half-seriously: perhaps it is time to bring back hardware-based controllers. It is worth taking seriously.
He also notes a second, smaller cloud-managed vendor in similar trouble.
Options for customers
For MSPs with Cambium in the field, the first priority is preserving operational control. Export full configuration and device inventories from cnMaestro today, while the service is still up. Stand up an on-premises instance and test migration on a small property before committing the portfolio. Contact distributors holding Cambium stock, Streakwave in North America and Bluechip and Dicker Data in Australia and New Zealand, to secure spares for the installed base, understanding that they are in as uncertain a position as anyone.
Review support contracts and warranty terms to establish who, if anyone, is now the counterparty. Then begin a contingency vendor evaluation in earnest. TP-Link Omada, which Maravedis identified as the fastest-maturing value-tier alternative, RUCKUS under Vistance, Calix SmartMDU, and the enterprise incumbents will all be fielding calls this week.
For property owners, the questions are simpler. Ask your MSP which vendor’s equipment is installed in your buildings. Ask whether the management platform is cloud-hosted by the vendor and what the continuity plan is if that vendor fails. Ask how vendor concentration is managed across the MSP’s portfolio. These questions belonged in every managed Wi-Fi RFP before this weekend. They are non-negotiable now.
One practical path worth examining is a vendor-agnostic orchestration layer. WiBUZ, whose wibipOS platform provides a single pane of glass across Ruckus, TIP OpenWiFi, Meraki, and Fortinet hardware and is pre-integrated with Ruckus, NetExperience, and Actiontec, was built for exactly the situation Cambium customers now face: managing mixed fleets during a transition without a rip-and-replace. An MSP that stands up a platform like this can bring replacement access points into service property by property while keeping a consistent operational view, rather than flipping an entire portfolio in one move and living in two consoles in the meantime.
The caveat is that our research documents no native Cambium integration on wibipOS today, so the value is on the destination side of the migration rather than in prolonging the life of the Cambium estate. Maravedis has done commissioned survey work for WiBUZ, and that survey of 65 MSPs found 75 percent relying on vendor-specific management systems that limit flexibility. This weekend is a case study in why that number matters.
Maravedis assessment
Cambium’s collapse is the first outright failure of a major WLAN vendor with a meaningful MDU installed base, and it will reshape how the market thinks about vendor risk. The near-term effect is a flight to perceived safety. RUCKUS, which Maravedis field research showed was losing its default-choice status among telecom consultants as price pressure mounted, will regain ground simply by being the vendor least likely to disappear.
TP-Link Omada, already the most aggressive challenger on price, inherits the value-tier position Cambium built, though it carries its own regulatory overhang in the US. Calix has an opening with ISP-affiliated MSPs seeking a platform backed by a financially stable public company.
The longer-term effect is more important. MSPs will start pricing vendor continuity into their platform decisions, and property owners will start demanding it in their contracts. Expect renewed interest in on-premises and hybrid management architectures, in escrow arrangements for cloud platform code and licensing, and in open, multi-vendor approaches such as TIP OpenWiFi and vendor-agnostic orchestration layers such as WiBUZ that reduce dependence on any single company’s survival.
Expect consultants to add financial due diligence on the equipment vendor to their scope, not just the MSP.
None of this helps the 260 people who lost their jobs without severance on Friday, the partners who cannot reach anyone at the company, or the residents in properties whose networks are now managed by a platform with no one behind it. The technology deserved better. The lesson for the rest of the industry is that a good product on a bad balance sheet is a bad product, and the market should have priced it that way sooner. Maravedis included.
Maravedis will update this analysis as the administrators, any acquirer of the fixed wireless assets, and the status of cnMaestro become clearer. MSPs and property owners with Cambium exposure who want to discuss contingency options can reach us at [email protected].
