Cambium Network Rescue · Decision Guide
Updated 2026-10-19 · By Jeff Johnson, Ambio Edge Networks
Update 2026-10-19: Univastu completed its purchase of Cambium’s ePMP and Enterprise businesses and cnMaestro on 2026-10-14, and Cambium now says cnMaestro Cloud “will continue to operate on a go-forward basis.” It follows the earlier commitment “through at least October 2026”, which is why we had used 2026-10-31 as a planning date. There is no published deadline to beat now. What you don’t have yet is the new owner’s support, licensing and service terms. Cambium also hasn’t withdrawn in writing its earlier warning that the cloud “may not support Enterprise devices post the end of October, 2026.” Your access points and radios are not the problem; the problem is the management plane, the dashboard you use to configure, upgrade and see them. You have four ways to handle it, and the right one can differ per product line.

Cloud Anchor outage, 2026-10-02 to about 2026-10-06
Operators in Cambium Community thread 108849 (posts #195–#222) reported that the Cloud Anchor (the Cambium cloud service that On-Premises 6.0 checks with for licences and for adding or removing devices) stopped answering licence and device-claim requests from about 2026-10-02. On-Premises 6.0 logins hung and licence sync failed until it came back around 2026-10-06. It matters for Option 2: On-Premises 6.0 still depends on the Anchor to add or delete devices. Cambium says that if the Anchor is disconnected, on-premises “will continue to work, but you will not be able to add or delete any devices.”
The decision
Pick per product line, not per company. If you run a mixed estate, you might keep PMP 450 on cloud under Airspan, move Wi-Fi and cnMatrix to On-Premises, and budget a hardware refresh for whatever is already end-of-sale. If you don’t know what you have per line, start with the network audit, $1,250 per site: inventory with end-of-sale dates and a port/VLAN map, yours to keep.
Change nothing structural. For lines Airspan bought, that is a reasonable choice: Airspan says acquired products keep support in cnMaestro cloud and on-premises. For ePMP and the Enterprise lines it is now the simplest choice too: Cambium says the cloud continues on a go-forward basis. Just know you are relying on a statement without published service terms.
Run cnMaestro On-Premises 6.0 as a virtual machine on a server you already own, or on a small mini PC you own (we can source it at cost + 15%), then repoint your devices to it (tell each one to report to the new server). New Cloud Anchor accounts get a 90-day cnMaestro X trial. At expiry, Cambium says on-premises instances “will degrade to Essentials” (the free tier), and that if the enterprise business is acquired, the buyer “will help you with an appropriate extension or replacement of trial.” It has now been acquired; Univastu hasn’t said anything about trial extensions as of 2026-10-19.
Cambium says: “Before the Cloud Anchor shuts down, we plan to release an on-premises image for Wi-Fi and Switches only, without any dependency on the Cloud Anchor.” No date has been given, and nothing had been released as of 2026-10-11.
Some integrators are offering hosted or managed cnMaestro On-Premises, at least one of them free for now. You swap Cambium’s cloud for a smaller provider’s. Hosting still runs on On-Premises 6.0, so the same Cloud Anchor dependency applies.
Retire the Cambium gear on a schedule and move to another vendor’s platform. This takes cnMaestro out of the picture, and it means new hardware.
After the trial
If you move On-Premises on the 90-day X trial and nobody extends it, the instance drops to Essentials. Here is what that means, from Cambium’s own pages.
Cambium’s cnMaestro X product page lists: APIs and webhooks; an MSP dashboard for managing multiple client networks; X Assurance analytics; Assists configuration checks; application control; one year of history for enterprise devices (two years for fixed wireless); and scale to 40,000 devices against 10,000 on Essentials. If you script against the API or run multiple tenants, plan for losing those at trial expiry.
Cambium’s guidance post lists features not supported on-premises: Network Assurance, some EasyPass options (Google, Azure and social logins, and UPSK), MarketApps, and NSE and RV22 devices, among others. Check each against how you use the cloud today before you commit to Option 2.
Before you move
The detail, with steps and fixes, is in the cnMaestro on-premises migration runbook. Items marked “operator reports” come from Cambium Community posts, not from Cambium.
Where we fit
We work on the network side: the controller, configuration, VLANs, routing, DHCP, SNMP, firewall and Wi-Fi. We don’t do RF path or frequency planning, alignment, tower work, licences, RMAs, warranty claims or firmware distribution. The configs, exports and documentation we produce are yours to keep. Looking for help beyond cnMaestro? See independent Cambium support.
On your existing hypervisor or a customer-owned mini PC (we can source it at cost + 15%). Devices repointed, overrides re-applied, and a backup taken before handover. Time and materials at $325/hr, with a written estimate before work starts.
From $3,500 (one site, up to three switch groups (a stack counts as one), 100 connected devices and 6 access points; larger estates and WISP networks priced by size on our assessment pricing page). Covers which option fits each product line and what to export first.
From $497/month; scope and onboarding quoted after an inventory. Monitoring only: alerts route to your team, no changes are included and there is no engineer response target. Any engineering work bills at $225/hr standard or $325/hr specialized, 1-hour minimum for remote work. Full scope on the Cambium monitoring section.
When a segment needs replacing, we design and run the network side of the move. For enterprise Wi-Fi and firewalls our default is Fortinet; we are a Fortinet Engage Partner (Advocate tier) and run Fortinet networks as a Sacramento Fortinet MSP and a Fortinet MSP in San Francisco. Fixed-wireless RF design stays with your RF team.
FAQ
As of 2026-10-19, Cambium says cnMaestro Cloud “will continue to operate on a go-forward basis” (2026-10-15, after Univastu completed its purchase of ePMP, the Enterprise business and cnMaestro on 2026-10-14). No end date or service terms are published, and Cambium has not withdrawn in writing its earlier warning that the cloud “may not support Enterprise devices post the end of October, 2026.” For lines Airspan bought, Airspan says it has no plan to discontinue cnMaestro. 2026-10-31 is no longer a date we plan around; keep your exports current instead.
No end-of-life notice has been published. Airspan says there is no plan to discontinue cnMaestro for the products it bought. The 8-K says Cambium kept the cnMaestro software and licensed it to Airspan. The Univastu purchase of Cambium includes cnMaestro, and Cambium says the cloud will continue on a go-forward basis; no end date or terms are published as of 2026-10-19.
Nothing Cambium has published says devices stop passing traffic when the cloud goes away. What is at risk is management: configuration changes, upgrades, onboarding and central visibility. Plan for losing those, not for losing traffic.
It is the Cambium cloud service that cnMaestro On-Premises 6.0 checks with for licensing and to add or delete devices. If it is disconnected, Cambium says on-premises keeps working but you cannot add or delete devices. Operators reported it unresponsive from about 2026-10-02 to 2026-10-06.
Cambium lists APIs and webhooks, the MSP dashboard, X Assurance, Assists, application control, longer history and higher device scale as cnMaestro X features. When the 90-day On-Premises trial ends without an extension, the instance degrades to Essentials and those go.
Airspan’s FAQ says: “As of today, we can only commit to supporting the products that have been acquired by Airspan.” For ePMP, Wi-Fi and cnMatrix devices in the same account, Airspan points you to Cambium. Those devices now belong to Cambium under Univastu, which has not published support terms yet, so plan them separately from the Airspan lines.
Yes, some integrators offer hosted or managed cnMaestro On-Premises. We don’t host it. We stand it up on hardware you own. If you go hosted, ask where it runs, how it is backed up, how you get your data out, and whose Cloud Anchor account your devices sit under.
No deadline, still worth doing
Time and materials at $325/hr, with a written estimate before any work starts. Our rough estimate for a typical stand-up is 4 to 16 hours depending on device count and product mix; the written estimate after we see your estate replaces that range. Not sure which option fits? Start with the network audit, $1,250 per site, then Continuity Monitoring from $497/month so you see outages while you decide. Business hours Monday to Friday, 8 AM–5 PM Pacific; we reply within one business day. See a sample assessment report (PDF) for how our written deliverables read.
