If you are looking for information on how to manually select a channel or enable/disable 2.4 or 5Ghz channel, then please search for that information as this pertains only to the rules associated with enabling manual channel selection and enabling 5GHz.
- When enabling 5GHz, you must have auto channel selection enabled. You can not enable 5Ghz and pick the Channel you want to use.
- You can only manually select a channel while using 2.4Ghz selections.
Failure to adhere to these instructions could cause a software issue preventing WiFi access at all. Corrective action would be to connect using a LAN cable and do a factory reset.
