Nighthawk AS2400 RAX30
My router randomly stops communicating/connecting to the internet. Specifically, the 2nd light from the top goes out. I can access the router and it tells me it cannot connect to the internet. ...
AT&T is our ISP. Hard wired into a Nighthawk AX5 AX4200 Model: RAX43 (living room). Hard wired into this router AS2400 RAX30 (office).
Works as expected 90% of the time. Then stops working and says the cable isn't connected.

Repeat question: What is the brand name and model number of the modem/ONT you use to connect to AT&T? Look on the label if you need to.
You are fortunate it works 90% of the time. Your configuration has a router connected downstream of another router. The two devices are constantly fighting over control of your network. This configuration is known as double NAT and it is not good. For reference, see this Netgear article:
https://kb.netgear.com/30186/What-is-double-NAT-and-why-is-it-bad
The easiest option is to configure your downstream router (RAX30) as a wired access point. Go to the Downloads section at the top of this page, feed in your router model number (RAX30) and download the users manual. Details on configuring your router as an access point start on page 70.
Most likely it will not be an issue, but be aware some features on your RAX30 will no longer be available when it is configured as an access point. The features disabled on your RAX30 are still available on your RAX43. See Netgear article here:
When you are configuring your RAX30, make sure you are connected to the user interface for the RAX30 and not to your RAX43.
AT&T modem is ARRIS BGW210-700. The date stamp is 8/16/2019.
Would this double NAT situation cause a router to fail completely? We had an older router in the living room and a much older router in the office; connected in line the same way. It worked that way with no problems for years. Then the one in the living room failed. I don't remember now the circumstances. Replaced it with the current living room router. Shortly thereafter, the one in the office failed. New routers, newer technology, more conflicts? The one in my office, the RAX30, was purchased one year ago today.
Thank you for your help. I'll read the articles and look at the configuration.

I do not believe a configuration or mis-configuration would make a device fail prematurely.
Your ARRIS BGW210-700 adds an additional layer of complication. It is a combination ONT/router. The internet has many stories of users having difficulty adding a router downstream. Primarily because the ARRIS BGW210-700 does not have a clear configuration option to disable the router function.
I scanned through a couple of the discussions and took away one recommendation. The recommendation was to leave the routing functions to the ARRIS BGW210-700 and to configure any downstream router as an access point. Yes, you can have more than one downstream access point.
Have you logged in to the user interface on your ARRIS BGW210-700? Suggest you do some on-line searches and review the findings relative to adding a downstream router.

Oh so true.
arris bgw210-700 bridge mode - Google Search
While the easiest option is AP mode, you then hit this:

As Kitsap says, there may be other options out there. Or replace the modem/router.
Here is a local suggestion that worked for one punter:
