Technicolor Technicolor-TC8305C: Sudden internet/connection dropping after May 23rd Update

Technicolor (Modems/Gateways) Technicolor-TC8305C: Sudden internet/connection dropping after May 23rd Update
After the May 23rd update, I am seeing complete network drops.

Also, I was forced to use the subtopic above, but here is the hardware specs of my Technicolor modem (ISP provided):

Model: CGM4140COM

Vendor: Technicolor

Hardware Revision: 2.0

Serial Number: 152930058043100639

Processor Speed: 1503 MHz

DRAM Total Memory: 1024 MB

DRAM Used Memory: 639 MB

DRAM Available Memory: 385 MB

Flash Total Memory: 8192 MB

Flash Used Memory: 138 MB

Flash Available Memory: 1910 MB

My Xbox is hardwared into my cable modem, as is my SmartTV.

When playing games (Overwatch) or streaming (Twitch), after a certain amount of time my connections (both TV and Xbox) drop completely, as if someone is removing and reseating the ethernet cables for each device.

I've already contacted my ISP for assistance and they did not find anything. They sent a tech out today and he also was unable to find any issue. No problems with hardware found, no issues with connections between the provider and my modem.

I've tried new cables, power cycling, resetting, rebooting, etc.. and the issue persists. While I can recreate it, the time it takes to appear is not consistent.

When it happens, I see a message on our TV saying the cable has been disconnected, and then it reconnects after a second or two.

If I'm using Twitch, it errors out saying my internet connection has failed.

If I'm playing a game (like Overwatch) it kicks me out of the game, and even out of my Live account. I can reconnect to it after 15 or so seconds, but the damage is done (disconnected from an active game).

Something with my Xbox is causing my cable modem to flip out - I also think this is odd that it is affecting all ports on the modem, not just the Xbox port. I've even swapped which port each device is using and the issue remains.

This only started happening after the May 23rd update.

What is going on here?

Can connect to internet, but not XBOX Live, using wireless or wired. Comcast Xfinity service

The Technicolor TC8305C has always been notorious when it comes to connectivity with Xbox Live.

If you have an additional router, set your Technicolor TC8305C to be operating in bridge mode. In this mode, the TC8305C will only function as a standard modem, while an additional router can function as the NAT device.

If you need help with bridge mode, consult your ISP, and they can help you configure this mode.
