Ethernet connection drops out but Windows 10 thinks there is no problem

I have a very strange problem where randomly, perhaps once a day, my web browsers and email will fail to retrieve data from the net, yet other minor services (e.g. Telegram messenger) continues to be connected. Windows 10 network settings shows the connection to be working and can't troubleshoot (because it finds no problem), whilst IPCONFIG commands report 'media disconnected'. I am only able to resolve the problem by rebooting the computer. The router is still connected to the Internet fine, as WiFi continues to work.

My setup is:

- Windows 10 PC

- Realtek PCIe GBE Family Controller

- Connected to router via Powerline

Steps tried:

- Updated Realtek driver = Fixes nothing

- Reset Powerline adapters (as I said, there has to be some kind of connection, as certain programs remain connected) = Fixes nothing

- Enable and disable all network drivers = Fixes nothing

- Troubleshoot network connection = reports "no issues"

- IPCONFIG = "media disconnected"

- Connect to router dashboard = Doesn't connect

It's as if just my browsers and email client lose their use of the network connection, whilst Windows 10 itself thinks it's still connected, but IPCONFIG thinks it isn't. Like parts of the system think they're connected and other parts think they're disconnected. This happens perhaps once a day at a random time, and can only be solved by rebooting. Then everything is fine again (but given that it takes 15 minutes to reboot my computer, it can seriously disrupt my workflow).

Any help or suggestions would be most welcome.

Hi

My name is Bernard and hopefully, this will help answer your question, upon reviewing your issue, seems that we need a full reset on the Internet and as well as redirect the connection, no worries we have sets of troubleshooting steps for this specific issue, follow the steps provided below:

First, I would suggest you to run in-built network adapter troubleshooter and check if that helps. Follow the steps below to run network adapter troubleshooter.

Press Windows + X and then click on Control panel.
Select Troubleshooting and in the left pane select View all.
Now select Network Adapter and follow the on screen instruction.
Make sure you have updated the latest version of Network Drivers from the manufacturer’s website.

Method 2: Update Network driver.

Press Windows Key + X and click on Device Manager.

Search for Network Adapter and expand it.

Right click on the Display Adapter and select Update driver and follow the prompt


Method 3:

If the issue persists, run the following command in command Prompt (Admin). Follow the steps below to do so.

Press Windows Key + X.
Click on Command prompt (Admin).
Type the following commands, and hit Enter after each command:
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
netsh winsock reset and press Enter
netsh int ip reset and press Enter
ipconfig /release and press Enter
ipconfig /renew and press Enter
ipconfig /flushdns and press Enter

Method 4: IP and DNS Setting
Type ncpa.cpl in Windows start > Right click on your network > Properties > Select Internet Protocol Version 4 (TCP/IPv4) > Hit properties > Make sure below ones are checked
Obtain an IP Address Automatically
Obtain DNS Server Address Automatically

Try Open DNS
Preferred DNS server : 208.67.222.222
Alternate DNS server : 208.67.220.220

If none will work from the above solution I suggest to do an in-place upgrade wherein it will upgrade the device to the latest version and repair all issues without deleting any files.

Note: before doing this make sure to create a restore point: https://support.microsoft.com/en-hk/help/402753...

3. On the License terms page, if you accept the license terms, select Accept.

4. On the What do you want to do? page, select Upgrade this PC now, and then select Next.

5. After downloading and installing, it should fix the issue.

Thanks. As mentioned, most of these methods have been tried already and do not solve the problem. Method 4 and parts of method 3 I can try however, the next time this problem occurs.

Sure, that would be the best and if ever you can check to your manufacturer if there are lower version of wireless driver or an updated version you can also try that, because there are times that it has something to do with compatibility :) hope this will fixed the issue.

Hi Lester. I tried methods 3 and 4 when this problem happened again, and they didn't solve the problem. The problem occurred again, yesterday. That means I have now tried all of the steps you recommended.

Any other suggestions, anyone?
