@Umrk111 I do not have any of the issues mentioned, for the 5Ghz band not showing do you have "Smart Connect" enabled ?

  @Sammael1069 Hello Sammael, Thank you for replying to my post. 

I don't have smart connect active on any of the active WIFI bands, which are:

1. 2.4 Ghz

2. 2.4 Ghz IoT

3. 5.0 Ghz IoT

The three bands above bands are all immediately accesible to all my devices. In fact, I am forced to use the 5 Ghz IoT band because the "real" 5Ghz band is invisible/not brodcasting/not working. And I haven't hidden this band either.

I am concerned that right out of the box, this brand new router already is not working as expected. I am awaiting customer support to assess this. But I am losing confidence in this routter each day I have it.  Really, I would expct a brend new device to work.

  @Umrk111 try using a CAT 6 or CAT 8 Ethernet cable. CAT 7 is NOT a recognized ethernet standard, and I've seen lot of people have issues with them, including dropped Ethernet connections and WiFi issues because of bad shielding in those cables. I'm using CAT 6 cables with no issues on WiFi or wired. 
 

How many IoT devices do you have that use the 5 GHz radio?  The vast majority of IoT devices only use 2.4 GHz.
