cap AX 5g randomly disappears

RouterOS Wireless Networking
1

I have two cap AX’s in my apartment and randomly noticed my phone wasn’t roaming, (it would roam to the 2.4 band of my living room ap but would quickly switch back to the 5g of the office ap)
I check with fedora any noticed that only 3 BSS’s were being reported under my SSID, the 2.4 and 5g of my office AP, and only the 2.4g band from the AP in the livingroom. I checked and didn’t seem anything wrong as it showed the 5g interface was running and had an SSID of “Corkery’s Router”. But strangely I did notice the channel was on 5885 which is valid for indoor use in the US.

The AP’s and the capsman server is currently on v7.19 RC 1

I read a forum mentioning to try and manually changing the channel and once I did the BSS of the 5g band on my living room was now being reported and I could roam perfectly as I once did. My config looks like this for WiFi

/interface wifi capsman

Keep in mind not all clients support UNII3

Good point! Interesting, I started reading into UNII-4 and read about how most devices don’t support it as of yet. I do have an iPhone 15 pro (ChatGPT claims it supports it but I’d rather test for my self and verify). I’ll set it manually and check again when I get home from work.

If this is the case then disregard the nothing burger of a post.


Update - I set the channel to 5885 and once again my laptop and iPhone are unable to see it. So it looks like both of those devices don’t support UNII-4 but my girlfriend’s S24 does. Removed UNII-4 from the channel pool.


Thanks again
