Windows 10: Computer causing internet to randomly disconnect every 45 mins or so

When I'm on my computer all devices lose connection to the router roughly every 40 mins to hour or so. I cant figure out what is going on. I thought it was my router it self but the problem only persist when I play games on my computer. If I am on any other device in my house I have no disconnects, but as soon as im on my computer it disconnects every device from my router including the computer, and it does it every 40 mins or so on repeat. The loss of connection last only about 30 secs or so but the disruptions has caused me to abandon using my computer altogether. Is there anything I can do

Internet Randomly Disconnects: Ethernet Network Adapter Keeps Disconnecting

My internet keeps randomly disconnecting throughout the day. Its a Dell (Windows 10Pro 22H2 - Dell Precision 5770) with Network Adapter: Realtek USB Gbe Family Controller Ethernet. I tried these steps below, no resolution yet:

One thing I noticed, everytime the internet randomly disconnects, I go to Device Manager, and notice the Realtek Network Adapter has totally disappeared from the list (with no option to reenable, even after finding it in Hidden devices).

I have to go through these two steps in this order to bring back internet.

1. Restart Computer
   
2. and then Restart Modem Router. ( I do restart modem by unplugging/plugging back in).
   

If the ethernet disconnects, Restarting the Modem won't work. Neither will Restarting Computer work. It has two be those two steps above in that specific order. I'm curious if having this resolution path, to understand why ethernet adapter disappears. If you can help target or specify why its occurring?

Already attempted this: and the problem still continues

1. Updated Dell Drivers
   
2. Windows Update
   
3. Network Adapter Troubleshooter
   
   
   
4. (a) Network Reset and (b) tried manually uninstalling/reinstalling network drivers separately
   
   
   
5. Tried manually downloading the software drivers at Realtek website Downloads - REALTEK
   
6. Replace cable just in case, but the other computer in home does not have internet randomly disconnect
   
7. Tried:
   

1. Disable these three in Device Manager: (a) Energy Efficient Internet (b) Green Ethernet (c) Wake on Magic Packet
   

I use the modem with another computer, and no issues whatsoever, until I got a new computer.

Note: this is different from previous question, since its looking at a problem/diagnosis path, rather power management settings.

 

My internet is getting disconnected for 5-10 sec every 10-15 mins in Windows 10. Need help

Hi Karthi,

A few possible reasons can cause the Windows Security sign-in notification box to appear. To help us identify the cause of this issue, we would like to know the following information:

• Is your computer connected to a school or work network domain?
• How are you connected to the Internet? Are you using your own Internet service provider?
• Have you made any changes to your computer before experiencing this issue?
• Do you experience this issue even if you connect to other networks?

In the meantime, let's run the Network troubleshooter. This troubleshooter finds and fixes common connection problems. Here's how:

• Click Start.
• Start typing Network problems, and then select
  Identify and repair network problems in the results.
• Follow the steps in the troubleshooter and see if that fixes the problem.

We also suggest that you disconnect your computer from the Internet and observe if the security sign-in notification box will appear.

Keep us updated on the status of the issue, and we will be glad to assist you further.

 

How long should the install and upgrade take.

Minimum, 45 mins to 2 hrs depending on the speed of your connection.

• Check to ensure there is disk activity (look at the hard disk LED light to confirm. If there is, keep waiting. If setup go beyond 2 to 3 hours, try the following steps.
• Power down the computer. Unplug it, then wait 20 mins to 1 hour.
• Disconnect it from the Internet (unplug Ethernet or turn off Wi-Fi).
• Plug it again, ensure it remains disconnected from the Internet then start computer.
• See if it completes setup.
• If setup completes and you see the desktop with the ability to click Start and launch programs, proceed to reconnect to the Internet.
