Cannot enter custom value of channel with mode 5GHz

[Edw125]

Describe the bug Hi. I found some problem with using this app. Cannot enter custom value of channel with mode 5GHz, value is 149 (see on screenshot), but "valid" number in form is between from 1 to 11. If I run app with default value (don't click on checkbox) I get an error:

мая 19 19:34:01 edward-IdeaPad-Gaming-3-16IAH7 wihotspot.desktop[44404]:     rfkill unblock wlan

If I run app in 2.4GHz frequency band hotspot starts successfully as both from checkbox and value 1 or other

To Reproduce Steps to reproduce the behavior:

1. enter the program
2. choose frequency band - 5Ghz
3. Try to enter value 149 channel
4. Error when enter value of channel
