Problem with Network Connectivity

Hi all,

I have recently set up a new PC. My problem is it randomly loses network connectivity and shows the yellow triangle next to the ethernet connection down in the system tray.

I have tested the network with a laptop connecting via the same cable and no problems.

The way I temporarily fix the problem is by disconnecting the cable and reconnecting it like in this video:



The little yellow triangle will then reappear randomly between 10 minutes to 2 hours later.

I have tried removing the device from device manager and reinstalling and the same with the driver but that didn't help.

Does anyone have any advice or know of a solution?

Thanks

Mark

The Triangle usually means limited connection, which is caused by the Gateway or Access Point. What does Ipconfig /all show when you put it into a Command Window.

Hey @bro67, sorry for the late reply!

I ran the ipconfig /all twice, once when the yellow triangle was showing and once when I removed and replaced the ethernet cable in the port. I'll paste them below:

I on't know if there is a difference between the 2 but I thought I'd post just in case!

Thanks in advance.

One thing is when disconnected you loose your IP and get the192 default one which wont work. The IP lease is very short go onto the router and increase the dhcp lease to 5 days when your lease runs out thats why it drops it can't renew or you could set a static ip

You have NetBIOS disabled enable that and disable ipv6 it's not used and increase traffic

Download my script here. When you have the issue again, run the script and get the log file created on your desktop uploaded and we should be able to determine the issue. https://windowsforum.com/threads/net...mation.223812/

Thank you to everyone who posted, especially @Samuria, I assigned a permanent IP to the PC through the router which solved the problem.

Apologies for taking a while to come back to you all.

Thanks again!

I should really remember to go to the router first in future!
