Modem And Wireless Router Predictably Drops Internet Connection After Power Outage?

Immediately after a power outage, my internet connection predictably drops after a set period of time or usage. It is either after about 30 min or 5-15 mins of watching Netflix. I have a modem hooked up to a wireless router and use the network on my iPhone, laptop and Roku. Since the problem, I have dropped to just having my laptop connected but this has not worked. The wireless network will disappear after the 5 - 20 mins, the light on the modem and router will show no internet (all other lights are normal). Internet connection will be reestablished if I either unplug both the modem and the router (not just one or the other) OR if I unplug the ethernet line from the modem to the router and plug it directly into my laptop (the internet light on the modem will go from "off" to "on"). Despite internet connection working from transferring from the router to the laptop if I connect it back to the router, the internet lights goes off again (resolves upon unplugging and plugging modem and router back in). The internet has not yet dropped when it is physically plugged into my laptop.

I have tried the following:

-Powercycling (temp fix until it crashes again)
-Plugging into a different outlet (I cannot connect it to a different phone line, only have 1 with DSL. Also, I do not have phone service or cable, just internet via DSL)
-Resetting modem
-Resetting 2 different routers
-Calling ISP, their test of the modem was inconclusive

Again, my wifi does not see my network whenever the internet is dropped or the ethernet cord is unplugged from the modem. The outlets I have it plugged into has some type of electrical issue, two electrical devices have shorted out in the room they are in. I do not think this issue is electrical, everything seems to have constant power (unless the power outage shorted out something in the modem). Below are some details of my modem and router. I will provide any additional info requested. I will gladly buy a new modem but I want to see if it can be fixed first.
