we have a few wireless networks that all consist out of cAP AC Access Points. Either one of the APs or the Router is the CAPsMAN. We had them configured with multiple Configurations that had multiple SSIDs. Since the last RouterOS Update (6.48.5 long-term or 6.49 stable) the APs only have one interface enabled. When you look in the CAPsMAN Interfaces list, all the inactive interfaces (either all 5G or all 2.4G) have an error “no supported channel”. When you connect to one of the APs directly, one of the wireless interfaces is disabled and there’s a virtual interface for other SSIDs that should send on the other frequency. So basically when you have two different SSIDs for your 2.4G and 5G Network, the 5G Network would try to send on the 2.4G interface.
We tried a lot of different configurations (manually setting frequency, bands, channels, etc.) but the only thing that worked was to configure the Hw. Supported Modes in the provisioning of the APs to all available. We then provisioned all the APs and they were able to select a channel on the right interfaces, but they didn’t send a SSID. So you had to double-click every interface and select a configuration for it. This works fine so far, but you can only select one Configuration, that only has one SSID.
We weren’t able to solve this issue so far, the only thing we can say is that all our customers that have Mikrotik cAP ACs have this issue.
I attached some screenshots of our configurations. The “befores” are from another customer so dont wonder why the names are different.
It would be great, if someone could provide me a solution here.
Each radio can either be 5g or 2g. You need a separate provisioning rule/entry for each radio. This means a dual band device would need 2 separate rules.
Ok, first off all thank you very much for your help!
I got it working the way i wanted it to by making two configurations that only set hardware configuration (band, channel, frequency,…) and used those as master configs on the two provisionings. Then i changed my old configurations for the two SSIDs to only set “software” configurations (SSID, Datapath, etc.) and used those as the slave configs on the two provisionings. Works perfectly fine!
Advanced mode \ Skip DFS cahnnels = disabled.
works fine for country = “ETSI 5.5-5.7 outdoor”
Mikrotik respects EU regulations, which demand DFS and TPC for all outdoor and some indoor channels. But the default setting is to skip channels demanding DFS (may be a bug). As soon as all the outdoor channels demand DFS, you have to allow using DFS-demanding channels or you get the “no supported channel” error.
