There are a few commands that we can use in Terminal that will give us some basic information. You can copy and past the commands into terminal and copy and past the information back into the post.

Also have you tried removing and re-adding the connection. Sometimes that helps if they made changes to the system

Will tell us the make and model of the WIFI device
Code: 
lspci | grep -i wireless

This command will tell us the link and signal quality.
Code: 
# iwconfig wlan0 | grep -i --color quality

This will retrieve the driver information
sudo lspci -nn -v -s your socket

You can tell the WIFI name by clicking on the WIFI symbol on the right (near the time) it will be the one on the list with a bullet next to it.

Have you tried turning off then on the WIFI on the system? Which can be done form the same place you located the name of the WIFI. From what I can see you have a good link and connection signal.

Has this affected you speed at all? Have you ran any speed test? What were the results?

Mine will sometimes show a lower signal that my windows system. Other times it will be the other way. There are times that I can be next the transmitter and have low signal.

I use ( WIFI Speed Test Program ) it shows ( ping-16ms ) ( download speed- 41.56mbps )
( upload speed 5.81 mbps )
I can only shut the internet off at the computer, when i reconnect WIFI Speed Test shows
( ping 31ms ) ( download speed-37.36 mbps ) ( upload speed-5.97 mbps )
My Linux never disconnects, its just slow sometimes, not all the time though.
Linux boots up is fine and shuts down is fine, is that ok? And to be expected?
Thanks Chuck

Yes this is normal for there to be a difference in signal strengths between Linux and Windows.

The upload and download speed look good as well.

You are welcome
