The control you shown this has not fixed anything - as it does not change anything on the router configuration.
We're always keen to learn however.
Help us out here with a bit more information.
What Netgear hardware is this?
What are you using to connect to the 5GHz wifi?
Apologies for the questions. But you can help people to help you by providing the information suggested in this forum's header:

They are there for a good reason.
The model number is 28743565.
That is not the model number. Your picture cuts off the bit that shows the model number.
Netgear81 is the SSID, the wifi source that you should connect to, using the password in the slot underneath it.
Is that what you are using when you get the "WiFi is out of range" message?

you can feed in the model number and find all the documentation for your hardware.
The CM400 in tour footer is a cable modem. It does not do wifi.
I repeat, what is the model number of your router?
It should begin with an R and look something like RXXXX.
It says that the WiFi is out of range when it is located right underneath my android box
This reads like a bad idea, for thermal reasons, for interference reasons, ... you might want to consider an Ethernet connection instead.
Why is it that when I select my 5G it says it is out of range...
Unclear and vague. Does this Android box list the 5G network name on air, or are you trying to connect it to a stored connection profile, ...? Depending on the age and source of this Android box, it might be unable to work on the channels currently operational on your router - for example if one or the other was designed and designated to work under a different regulatory domain.
And the Android box is ...?
Can you see and connect the router 5G network from other devices, e.g. a mobile phone?
What do you see on this Android box? A photo might help to understand your question a little bit better.
Not up to speed, but no so long ago the Fire TV and Firestick clients had no support for the DFS channels https://www.amazonforum.com/forums/devices/fire-tv/466853-fire-stick-cant-find-5g-wifi
For the Bravia, similar limitations might apply ... if really located just above -> BRAVIA TV Support: How to connect the TV to a network using a wired connection
If you are located in the US, you might try to change change the router to channels 36-48 or 149-165 - these are the only non-DFS channels under FCC regulatory.
11? That is the 2.4Ghz area. 5Ghz is 36 - 48 by 4's or for a 2nd band on some routers for 5Ghz 149 -161 by 4's
Seems you do not have the 5Ghz on by any chance?
So far you have mentiponed R6700v2 and R6700. They are not the same. Diofferent hatrdware that needs different firwnmare.
My router channel only goes up to 11
That is a channel for 2.4 GHz wifi, as @schumaku says. It has nothing to do with 5 GHz wifi.
Any devices you own that don't support 5 GHz will see only the 2.4 GHz.
We still do not know what you are trying to connect to what. Unless you have changed it, they need to connect to a wifi source that has the Netgear81 SSID shown on the label on your router.
