Lost 50 signal

[ChuckT]

RT-AC66U Router has developed a wireless problem?
Wife uses 24 GHz band with her iPhone, I _could_ use 24 or 50 GHZ band with my Note3 Android.
Today I noticed that my phone no longer displayed the 59 GHz band as available.
Router is in middle of the house so range is not an issued. Wired connections (4) seem to be good. Wireless connections worked well enough that I haven't found it necessary to keep a check them.
LEDs on Router say function is 100%
If I sign on to router console from my desktop computer via wired connections how can I check 50 GHz the wireless signal?

Is the 5GHz band using Auto channels? They may be assigning a channel outside of the client's capabilities?

Try assigning a manual channel for the 5GHz band and if necessary, test each one to see if the client can see and connect. I would recommend rebooting the router after each change you make in the gui too. And then give it a good 5 minutes to stabilize before you conclude it works or not.

Thanks, sounds like good advice.
