    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

    There is known problem with the Technicolor TC8305C and the latest version of firmware for this device, which were pushed out 10-22-2014. There's no estimation on when to expect an update to fix the problem with the current version of firmware.

    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.

    Is the reason why many people are randomly disconnecting because of our router model?

    Take a look at this Comcast thread: forums.comcast.com/.../2398585

    This is a known issue with the Technicolor TC8305C Gateways from Xfinity. They pushed out a firmware update that is causing drops. A Comcast CSR recommended to go to a Comcast store and switch out the Gateway for the Arris TG862.

    Nat: Strict on Xbox1 Nat: Open on COD AW

    It's a Technicolor TC8305C

    Xbox Live Connection Dropping every 15 minutes or so.

    Everyone that is having problems with connecting to cod or destiny and has the technicolor Tc8305c needs to either switch their modem with Comcast or whoever they've got or get their own modem. The technicolor is not compatible with Xbox. I have not even
    been able to play games online because of connection drops. Switching the modem will fix everything.
