Cambium Network Rescue · Independent Support
Cambium Networks Limited entered administration on September 14, 2026 (RSM UK Restructuring Advisory appointed), days after its September 10 notice and a company-wide layoff. The ePMP sectors, cnPilot access points, and PTP backhaul links in your network keep passing traffic — but the support path, the firmware pipeline, and the long-term future of the cnMaestro cloud behind them are now uncertain. We offer independent Cambium support and migration planning: export and preserve your cnMaestro data while it remains reachable, monitor your radios without any vendor cloud, and migrate only what actually needs migration — on your schedule, not in a panic. We are an independent engineering firm with no affiliation to Cambium Networks or its administrators.
The Situation
There is a lot of rumor. Here is what is on the record, and the operational read.
Cambium Networks Limited is now formally in administration — RSM UK Restructuring Advisory appointed Sept 14, per the company’s SEC 8-K, following the Sept 10 notice and a layoff of roughly 260 staff worldwide.
cnMaestro shows operational on Cambium’s status page as of this writing — but there is no continuity guarantee, no named buyer, and public reporting suggests pre-filing efforts to find one did not succeed. Administrators say they will seek buyers for “some or all business lines.”
The hardware doesn’t know any of this is happening. What’s at risk is the management plane and the support path — a software problem, and software problems have solutions.
Orphaned estates need independent support for years, not weeks. The urgent part is preserving your cnMaestro data before anything goes dark.

Do This This Week
Whether or not you ever call us, do these four things now. The window to act calmly is while the cloud is still up.
Device inventory, configurations, topology, performance baselines, license state — export whatever cnMaestro will give you, today. If the cloud goes dark, this data is the difference between a managed transition and starting from zero. This is the single most time-sensitive item on this page.
What’s on the shelf, what firmware is on every radio, which device credentials and SNMP strings actually work. Firmware downloads and RMAs may stop being available; your spares closet just became your supply chain.
Cambium radios speak standard SNMP. Availability, RF and link metrics, interface counters, and hardware health can all be watched without any Cambium cloud — so a controller outage doesn’t make you blind. This is precisely what our monitoring stack does.
Networks that work fine should not be torn down because a vendor failed. Rank every segment by real risk: Wi-Fi migrates easily when the time comes; point-to-point and PMP deserve deliberate, budgeted planning. Replace on your schedule, not the administrator’s.
How We Help
Independent, senior-engineer-led, and priced so you know the number before we start. Every engagement begins with the audit; nothing is sold that the audit doesn’t justify.
Fixed scope, 5 business days. cnMaestro export assistance (inventory, configs, topology — preserved to your storage), firmware/version inventory, SNMP & credential review, cloud-dependency review, spares & EOL risk list, an “if cnMaestro disappears” impact memo, a prioritized migration roadmap, and a 60-minute executive handoff. $1,500 up to 25 devices · $4,500 up to 100 · $7,500+ multi-site & WISP · enterprise and public-sector estates scoped individually (typically $10k+, procurement-ready deliverables included).
Vendor-independent SNMP monitoring for ePMP, PMP, cnPilot, Xirrus, and PTP families: availability, link & RF metrics, interface stats, hardware health. Tuned alerting to a senior engineer, a branded live portal for your team, config-archive workflow, and a monthly health report. An operational continuity layer while the vendor cloud is uncertain — we are explicit that it is not a cnMaestro feature clone, and that honesty is why it works. Add cnMaestro Data Escrow (from $149/mo): scheduled automated export and integrity-checked offsite preservation of your inventory, configs, and topology, so a cloud shutdown can never take your records with it.
When the audit says a Wi-Fi estate should move, we design and execute the migration — typically to Fortinet FortiAP/FortiGate as an integrated security and network fabric (we are a Fortinet partner with hardware supply), scoped site-by-site with staged cutover and zero-drama rollback plans. Point-to-point and CBRS replacements are handled as advisory and project management with specialist field partners. Prefer to keep the controller you know? Ask about the cnMaestro On-Prem Lifeboat — we stand up and host the self-hosted cnMaestro instance for your estate while the installers are still obtainable, so your management plane stops depending on the vendor’s cloud.
Coverage
Not a cnMaestro feature clone — an independent operational layer. Our observability stack (LibreNMS, Prometheus, Grafana) carries native device support and MIBs for the Cambium lines below, so your monitoring survives whatever happens to the vendor cloud. If your family isn’t listed, ask; if it speaks SNMP, we can almost certainly watch it.
ePMP APs and subscriber modules with per-SM visibility; PMP 450 family via Cambium MIBs. Sector availability, registered SM counts, RF signal metrics, throughput per link — the operational view a WISP or municipal operator actually runs on.
cnPilot enterprise and router lines plus Xirrus AOS arrays: AP reachability, client counts, radio health, uplink state. Enough visibility to run the estate confidently for years — or to baseline it precisely ahead of a migration.
The links your whole network hangs from. Link state, modulation, receive power, error counters via the PTP MIBs — with alerting tuned so a degrading licensed-band or 5 GHz link pages a senior engineer before it drops, not after.
Switches, firewalls, power, WAN links, VPN tunnels — the same managed-monitoring platform we run for payment-processing and multi-site clients extends past the Cambium estate to the whole network, with zero-trust remote access and no inbound ports.
Who This Is For
The installed base spans public infrastructure and private networks alike. The common thread: the network works, the vendor’s future is uncertain, and ripping it out this quarter was never in the budget.
Downtown Wi-Fi, public safety links, light-pole APs — often grant-funded, always scrutinized. Public infrastructure investment shouldn’t have a shorter service life than the poles it’s mounted on. A continuity audit is how you avoid an unnecessary emergency procurement.
cnPilot and Xirrus estates across buildings, E-Rate-funded deployments, small IT teams. We stabilize now, document everything, and produce the migration plan your budget cycle can actually absorb.
ePMP/PMP sectors and PTP backhaul are the business. You know the gear better than anyone — what we sell is time and an outside set of senior eyes: export tooling, independent monitoring, and a defensible replacement ranking, fixed fee, fast turnaround.
A pair of PTP bridges between buildings, a cnPilot ceiling estate, a yard network on ePMP. Usually installed by an integrator who has also moved on. We take ownership: monitor it, support it, and migrate it when it’s actually time.
FAQ
Cambium Networks Limited formally entered administration on September 14, 2026 — RSM UK Restructuring Advisory was appointed, per the company’s SEC filing — following its September 10 notice and a layoff of roughly 260 employees worldwide. The administrators say they will seek buyers for some or all business lines; none has been named, and public reporting suggests pre-filing buyer efforts did not succeed. Nothing specific has been guaranteed about enterprise Wi-Fi, cnMaestro, or switching.
Nobody knows — that’s the risk. cnMaestro and Cambium’s support portals remain operational as of this writing, and no shutdown has been announced. But it is a cloud service run by a company in an insolvency process; if it ever goes dark, you lose the management plane while the radios keep working. Export your inventory, configs, and topology now, while it’s reachable, and stand up independent monitoring so a cloud outage can’t blind you.
Almost certainly not this quarter. Don’t panic-forklift a network that works. What you need immediately is continuity — preserved data, spares inventory, monitoring — and a ranked plan so replacement happens on your budget cycle. That plan is exactly what the Rescue Audit produces.
Yes. Cambium gear speaks standard SNMP, and our stack has native support for ePMP, cnPilot, Xirrus AOS, and the PTP/PMP families. You get availability, RF and link metrics, alerting to a senior engineer, and a live portal — fully independent of any vendor cloud, Cambium’s or anyone else’s.
The Rescue Audit is fixed-scope from $1,500 (up to 25 devices; $4,500 to 100; $7,500+ multi-site/WISP; enterprise and public-sector estates scoped individually) and delivers in 5 business days. Continuity Monitoring runs from $497/month plus onboarding. Booking to kickoff is typically under a week — the cnMaestro export can begin on day one.
No. We’re an independent California network engineering firm — senior-engineer-led, Cisco and Fortinet certified, running managed networks for payment-processing and multi-site clients. That independence is the point: our only interest is keeping your network alive and migrating it when it genuinely makes sense.
