Windows 7: Computer keeps loosing internet connection but other devices do not.

Computer keeps loosing internet connection but other devices do not.

About once a week or more my computer looses its internet connection. I know this because I get the ! in the yellow triangle or the red x over the monitor icon in the task bar. I will also not be able to reach any web site. The strange part is that other devices within the house do not loose their internet connection. Items such as cell phones, tablets, Alexa, and my TV do not loose their connection. They gain access to the internet via wireless router which is part of the same computer system. These items connect perfect.
Here is information I believe to be important.
Internet via Spectrum cable. Motorola modem, Surfboard, SB6141. tp-link wireless router.
Windows 7 Professional w/service pack 1
Intel core i3-4170 cpu@3.70GH. 16 GB Ram - 15.9 GB usable. System Type 64-bit
Every time the computer looses the internet connection I unplug the modem and restart the computer and plug in the modem again. When the modem and computer start back up ever thing is fine till the next time the computer looses connection. I have tried different cords between computer, wireless router, and modem and that does not help. I have tried different ports on the back of the wireless router and that did not help. Any and all help will be greatly appreciated. Thanks, John

Are you using a cable or wireless? Open a CMD prompt type
Ipconfig /all

Go into the Network and Sharing center and select Change Adaptor Settings,

Right click on the Adaptor you use for connecting to the router, then select properties and Configure

Select the Power Management tab and make sure that the Allow the computer to switch off this device to save power option is NOT checked

"OK" back out and the system should not lose connection

In 90+ percent of cases like yours, that I'm asked to fix it's the power saving setting that is the cause - Especially suspect where all the other devices are working fine. You may also have to check the settings of any manufacturer supplied installed on the system "Tools" as these often duplicate Standard function.

Hello, I followed instructions and yes, "Allow the computer to switch off this device to save power" option was checked. I unchecked it as advised. Unfortunately I am not knowledgeable enough to know how to "check the settings of any manufacturer supplied installed on the system "Tools" as these often duplicate Standard function." Would you please walk me through this step? Thanks, John

My system has a modem supplied by Spectrum. It has a ethernet cable running between the modem, wireless router and computer.
I did try the Ipconfig /all and can up with all kinds of stuff way, way over my knowledge level. It did show a bunch of adapters and other stuff.
Thanks,
John

You need to post results of ipconfig as it may give us some clues when we see both results

If you run your system for a while and the same issue is still present, then this could be down to a manufacturer utility, but could also be something Else. Finding an application that the manufacturer added is often just a case of checking the documentation that came with the system or checking the manufacturer website, It used to be that most Dell, HP, Etc came with their own Networking setup tool but is less likely since Windows 7

Have you updated the Realtek Ethernet driver?. I had problems with the old driver & I updated & now it works perfectly. The latest driver was released in August 2018 & you should be able to download it from here.

Realtek

You will need to select the correct version for your computer.

Open device manager. Do you see any yellow alerts of missing drivers?
