Nighthawk AS2400 RAX30

Question

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. Says to check that the cable is connected. That's not the problem. I take the cable out of the router and plug it directly into my laptop and the laptop connects to the internet.

I've tried turning it off for a while. Sometimes when it comes up it works and sometimes it doesn't. There doesn't appear to be a common theme to when this happens. I've had the router for right at a year. This started happening about 3 months ago. It will go weeks and be fine. Came in yesterday morning for work, no light. Turned it off all day and plugged directly into my laptop for work. After work, turned it back on and nothing.

We have another Nighthawk router in another part of the house. It hasn't done this. Its on and working while this one says it cannot connect. Clearly, since I can take the cable and plug it directly into the laptop, its not the cable.

Any ideas?

Thanks!

AT&amp;T is our ISP.&nbsp; Hard wired into a Nighthawk AX5 AX4200 Model: RAX43 (living room).&nbsp; Hard wired into this router AS2400 RAX30 (office).&nbsp;Works as expected 90% of the time.&nbsp; Then stops working and says the cable isn't connected.

AT&amp;T modem is ARRIS BGW210-700.&nbsp; The date stamp is 8/16/2019.Would this double NAT situation cause a router to fail completely?&nbsp; We had an older router in the living room and a much older router in the office; connected in line the same way.&nbsp; It worked that way with no problems for years.&nbsp; Then the one in the living room failed.&nbsp; I don't remember now the circumstances.&nbsp; Replaced it with the current living room router.&nbsp; Shortly&nbsp; thereafter, the one in the office failed.&nbsp; New routers, newer technology, more conflicts?&nbsp; The one in my office, the RAX30, was purchased one year ago today.&nbsp;Thank you for your help.&nbsp; I'll read the articles and look at the configuration.Karen&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
