New Tri-Band router and cannot see/intermittent one band SSID broadcast and can't connect to it.
Brand new Archer C4000. Performed quick setup and modified band names to my specific need. The 5G_1 band does not always broadcast the SSID (broadcast is definitely on) and when I am able to see it I am unable to connect/log in by either computer (Windows 10) or iPhone 11.
Assistance please for this brand new product.
