My Internet keeps disconnecting from my computer and nothing else

[StarSample]

So as the title says my computer keeps disconnecting from the internet and nothing else, but what is strange is that in the bottom right it says I am connected to the internet, but things just stop loading/updating. For example I'll be in a Skype call and all of sudden it just freezes and won't come back unless i disconnect from the internet and reconnect manually. This get especially annoying when playing video games or just talking with friends. Also should mention this started when we got our new modem. Any help is appreciated, and yes I have tried uninstalling my network drivers and reinstalling them.

New modem or new modem/router? Make and model? Who manages it?

Is your computer directly connected to the new device? Check the ethernet cable between your computer and the new device.

May be loose.

Or try another known working ethernet cable in place of the existing cable.

Check your network adapter card settings: e.g., "speed and duplex". Try a manual setting to match the new versus some "automatic" setting. Or vice versa. If manual, try auto.

Sorry for the late reply, but we just got a new xfinity modem that they sent us. I am connected through wireless, and I have updated my network drivers

Wireless can be problematic and sometimes it does not take much to degrade the signal paths with subsequent loss of connectivity.

Need to narrow down where along the way the connectivity is being lost....

Which make and model modem from Xfinity?

Is your setup:

1) Xfinity -----coax-----> Xfinity modem ----ethernet cable -----> router ~~~~~~wireless~~~~> to your computer

or

2) Xfinity -----coax-----> Xfinity modem/router ~~~~~~wireless~~~~~> to your computer?

Just your computer or all devices on the network?

Try moving the wireless source (i.e., the router or modem/router higher up) just for testing purposes. Likewise try moving your computer around some - closer if you can. Try antenna extenders or a USB extension cable as applicable to raise the wireless adapter on your computer.

See if you can find some arrangement that stabilizes the connections. Then you will know that everything is correctly configured and properly working. Then the focus will be putting things back where you need them to be while hopefully maintaining stable connectivity.

Well i don't know the make and model i'll check it in a little bit, but i know that are setup is like the 2 scenario. Also this all started with he new modem, its still in the same spot where it was working perfectly fine before. OK so the model number is TG1682G don't if that's gonna help.

That does help.

Knowing the make and model is important because every device is different. Even though they do basically the same thing(s).

Do you have the User Guide?

If not, here:

https://secure.xfinity.com/anon.comcastonline2/support/help/faqs/wireless_gateway/HOW5220_Wireless_Gateway_3_UserGuide_06_19_15.pdf

Please do verify that I have linked to the correct User Guide.

On page 21 there is a list of factors that affect wireless performance.

Although nothing appears to have changed, the change is the modem itself. It will not transmit, receive, or otherwise perform as did the original modem.

Maybe in some small manner just enough to cause the problem - especially if there is some other contributing factor that the original modem ignored. Or maybe that factor was simply too small to impact the original modem.

For example: trying another known working ethernet cable is a common troubleshooting method. The ethernet cables that come with a device are made as cheaply as possible. Does not take much for a plug to start losing connectivity on one pin or another. In fact, a cable may even "work" but not up to full specs.

Starting on Page 30 there four tables explaining the indicator LEDs. Take a look at the LED patterns expecially when there are disconnects.

Read through the Troubleshooting Section starting on Page 35. Some of it may seem trivial and unimportant. However, you may note something that combined with something else you know (or happen to realize) might narrow things down to the problem.

If you do not have or use IPv6, disable the IPv6 protocol on your computer(s).
