I understand the GUI only allows lower 5ghz channels. I also believe the higher channels 149 etc is used as a backhaul channel. Has anyone figured out a way to force a higher channel via Telnet similar to seperating the SSID. My apartment is so congested with 36-48 channels its not funny.

I was poking around with the config, and found that this may work. I've tested it for a short while, but then reverted back to channel 48. It would be interesting if others test this and report back here.
I did notice that there was some code in the wifison-monitor.sh script that contains some logic regarding DFS channels. This is the same script that monitors the ssids of 2.4 and 5 GHz channels and changes them back to be the same. You may need to disable the monitor for this to work as well. Also, I don't know if the DLS channels work well with the Orbi or not. Basically, this is untested. All I can verify is that it does actually changes the Orbi router to use the new channel. Try at your own risk and post your stories back here. You might want to make sure you can still access via 2.4 Ghz or ethernet in the case that the 5Ghz channel breaks.
// Enable telnet access on your router
http://192.168.1.1/debug.htm
check the box to enable telnet
// telnet to your router
telnet 192.168.1.1
// these commands will show your current 5Ghz channel
config get wla_hidden_channel
config get wla_channel
// set new channel
config set wla_hidden_channel=64
config set wla_channel=64
// I'm not sure if the monitor should be disabled or not. To disable the monitor, use the following command
config set wifison-monitor_stop=1
// commit changes
config commit
// reboot
reboot
