Hi Sureal,
If your AP country code is NL, please ignore my previous reply which was based on US country code. Each Country Code has the different settings for channel.
It's correct that there is no channel setting for Country Code "Netherlands"(NL).
And R310 should support 5G channel range in "36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128,132,136" by default in AP setting. I tried one R310(Master) in NL countrycode with version 200.610.1.312 and can not reproduce your problem.
Please check AP 5G channel range settings in webUI:
1. Access Points Tab->Select Summary, click Edit button:
All channels(36-64,100-136) are shown and selected in Radio A/N/AC(5G) tab.
2. Access Points Tab->Select R310 AP, click Edit button:
All channels (36-64,100-136) are shown and selected in Radio A/N/AC(5G) tab.
And please also login R310(Master) via ssh and check the same as below steps:
1. Enables privileged commands:
ruckus> en
2. Goes into AP mode to check:
ruckus# ap-mode
You have all rights in this mode.
3. Check AP model and version for R310:
ruckus(ap-mode)# get version
Ruckus R310 Multimedia Hotzone Wireless AP
Version: 200.6.10.1.312
OK
4. Check AP 5G channels:
ruckus(ap-mode)# get channelavailability wifi1
