I have been seeing a yellow mark on the network connection icon in the system tray. What I want to do is find a way to really test the network connection on my computer. Will a loopback cable work for this and if yes what tests can be run? thx as always in advance.

What is the make and model of this computer?

 

What do you see if you right click on the Yellow mark?

 

Are there any errors in the Device Manager?

 

One thing you can try would be to reset the TCP/IP

 

Go to Start> Run and type in cmd and press Enter.

A screen similar to the one below will open.

There will be a blinking white cursor, type netsh int ip reset c:\resetlog.txt and then press Enter.

 Reboot the computer.


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

the mb is an asus about 4 years old on a small home wired network to a router with a second computer going to the router also. if i right click on the yellow mark it indicates no network connection. in device manager there are no issues with hardware. i just got a small program to test the speed across my home network to the second computer and it seems to work ok. i am inclined to think something is happening to the TCP/IP stack and will use the command line you have indicated to reset it.
