Channel reselect interval issue after upgrading to 7.15 (hAP ax²)

Hello,

Since upgrading to 7.15 from 7.14 ‘wifi1’ is requiring the “Reselect Interval” under channel settings to be defined. I tried hiding the setting by clicking “^” then apply, but nothing.

From console it seems fine, but still the same result from the web interface:

I also tried to create a new wifi interface to see what would happen, same issue.

if I must define this setting to make wifi changes from the web interface, what is the right solution here?

Same problem here.

Until someone advises otherwise, I just used “01:00:00” for both fields. According to the RouterOS manual, I think this means it’ll rescan the frequencies every day and reselect the most appropriate channel(s).

several hap AX3 boxes and one AX2 with v7.15 upgraded from v7.14, v7.14.2 and v7.14.3 : none of them require me to configure Reselect interval.
I have it empty and “collapsed”.

Why does it expect two values at all? How are you expected to configure an internal with two separate values?

Random within specified interval. Mathematically a perfectly valid interval (closed interval as it has lower and upper bounds).

According to docs: “Specifying intervall will allow the system to select this interval dynamically and randomly”

Winbox bug? Nope. It is perfectly correct to have two fields.

When I set “Reselect Interval” via a “Channel” common config setting and then apply this “Channel” to a wireless interface the "Reselect Interval " remains red.

It seems to work in Winbox, just not the Web UI:

Hey guys,

I sent the following to the Mikrotik Support:
“I have a question about the reselect interval. How should the time interval be understood? Does 01:00:00 - 01:00:00 mean that every day at 1 AM the channels are scanned and adjusted?
Or does an interval have to be specified because the scan runs for a certain time for example 01:00:00 - 02:00:00?”

The answer was:
"Thank you for contacting MikroTik Support.
If you were to enter "01:00:00 - 02:00:00 " it would translate to -.reselect-interval=1h..2h, which itself means that wifi interface will evaluate if there is better available channel, in a random interval every 1 to 2 hours. I could happen in any interval between these two values.

Specifies when the interface should rescan channel availability and select the most appropriate one to use. Specifying interval will allow the system to select this interval dynamically and randomly. This helps to avoid a situation when many APs at the same time scan the network, select the same channel, and prefer to use it at the same time. reselect-interval uses a background scan.
The reselect process will choose the most suitable channel considering the number of networks in the channel, channel usage, and overlap with networks in adjacent channels. It can be used with a list of frequencies defined, or with frequency not set - using all supported frequencies.
It is not enabled by default.

If there are issues with entering the interval via WebFig, please check 7.17beta release tree."

I hope it is useful for some of you.

Documentation is also providing this info:
