Home Gateway loses service several times each week

Question

Hello!
My parent's have a PACE American Gateway which connects us to our internet, wi-fi, and cable. For the past several months, the gateway seems to lose (and reboot) its connections. The normal state of the gateway is as follows:
Power: solid green light
Wireless: flashing green light
Broadband: solid green light
HomePNA: flashing green light
Service: solid green light
When the connections are lost, all of the lights go solid red, and off (power light stays on). There is also a clicking noise as the system reboots. This is happening several times a week. I know there's construction going on at the end of my street, but I doubt that's the reason it keeps losing/rebooting the signals. We also have a battery backup attached to the gateway.

I also know that the Ipv6 standard was added to our Uverse, but that was done a few days ago. I checked the cords and everything is connected properly. What can be done to get this issue resolved? My parents would prefer not to have a technician come out, but if they have to, they have to.
Any help would be greatly appreciated. Thank you!

You can try using the T&R tool here: https://ufix.att.com/portal/index.html?tGseq=validate__referrerId_3__ref_&AUTHN_ACTION=PASSWD_LOGIN#home
You will need the account holders log in credentials to access it.  It will run tests and set up a dispatch if needed.  I would also load it on a mobile device so once it goes down you can run it from that to see if it finds the issue.
