Very slow CoxWiFi hotspot from my cox panoramic

I've used this hotspot that runs off of my panoramic modem for about a year now with zero performance issues, but as of early last month there was a maintenance for cox in my area for about 3-4 days. During the last 2 days of the maintenance my CoxWifi hotspot that runs off of my panoramic modem started to perform VERY unstable and VERY slow. Examples would be before the whole maintenance thing I could browse any website and it would load perfectly like it should, but now on EVERY website it takes forever to load or doesn't load at all and I have to spam the refresh button. It also has a very unstable connection to any website that I'm currently on at any moment like it would stop loading the page half way through. The max devices I have connected on that hotspot is only 1.

Before I've decided to do anything. I chose to wait it out for a good week to see if it went back to normal, but as you can see it's been almost a month now and it's still the same.

Now I'll list out what I've done.

I started with the basics by unplugging the power cable for the modem for about 2mins and plugged back in.

I restarted the modem from my phone using the app.

I even went into my cox account to turn on and off the CoxWiFI hotspot.

Another option i thought about doing is factory resetting the modem, but I doubt it'll fix the problem. 

I've called customer service twice. On the first call all they did was file a report for me as they asked me questions about my problems. On the second call all they did was turn off and on my CoxWiFi hotspot. What I found funny about the second call was that I asked if there's a way to directly have the CoxWiFi hotspot be reset and the response was no. 

After those calls I felt abandoned like even COX CUSTOMER SERVICE can't help solve the problem I have when using their own feature that they provide? 

What's the whole point of having the hotspot feature at this point when it performs like **bleep** now?

My last problem I had to fix it myself not even customer service helped. I'm guessing I might have to solve this one myself too, but I hope someone does have a solution.
