I can sometimes gain access via direct connection to wired ethernet port

I am having the same problem and have had to reset three times now.  

 

It started a couple of months ago.  I can sometimes gain access via direct connection to wired ethernet port, but the connection will drop periodically.  When it happens, I can see that no IP address is being assigned.

 

Only a factory reset will restore functionality.  The last time i did this, it lasted a couple of months.  The last two times, it only lasted a few hours before the problem reoccurred.

 

DHCP seems to be failing to wired and wireless connections.

 

The problem is the same with two different modems.

 

 

Router:

Netgear MR60

 

Modems tested: 

1. Netgear LM1200

2. T-Mobile 5g Gateway
