Hi:
My OEM UBNT M5 seems to have a top center frequency of 5825 MHz (20 MHz ch). Could someone confirm that by using AREDN firmware this can move up to 5920/Ch 184 (5 MHz?)
Once we place AREDN firmware on these devices, can they ever be taken back to factory/OEM firmware?
Can the factory firmware be read or backed-up before upgrading to AREDN?
Thanks

Yes.

Not to my knowledge.
You can likely download your current firmware from Ubiquiti: https://ui.com/download/airmax-m/ .
Then restore it later with the TFTP method.

Yes, but 5 MHz is not recommended.
5 MHz bandwidth is needed when the distance between nodes is greater than 44 miles.
Why are you considering 5 MHz bandwidth?
Why are you considering the highest channel?

"Yes, but 5 MHz is not recommended.

I typically run this on long distances (to improve threshold) or when I have path anomalies. Looking for high quality/stability and don't need high throughput (used to transport a few VoIP applications).
"Why are you considering the highest channel?"
That is just the way I poorly worded it :) I don't need to use that specific one. I noted 5 MHz to express that the band edge is 2.5 MHz above that specified center frequency.
I am interested in why you recommend against using 5 MHz channels.

Hi, Greg:
Mikrotik does not play well with other manufacturers at 5 MHz bandwidth.
IMHO, as long as there is sufficient SNR in a link, bandwidth does not affect quality nor stability.
If your 'long distances' are ~44 miles or more, 5 MHz bandwidth is a good choice.
If more than 2 stations share a channel, a wider bandwidth may grant more channel availability.
