HP Laptop, Win-8.1, Chrome browser, True VDSL

 

Operating normally early in day.  Last evening, opened computer and could only get limited connection, yellow triangle overlaying signal strength display.  Tried cycling router several times, called True: no problem with account and showing connection OK.

Sure enough, I opened another laptop and it connected normally as did a tablet and my mobile.

Obviously some kind of problem with my network connection.  I tried closing the connection and reopening it again and Windows troubleshooting tool which never seems to detect anything...and it didn't.

Any suggestions?

Seems like there is no exact single reason for this.

A couple of troubleshooting descriptions on the net.

 

This one looks promising:

(can't tell whether the text description matches Windows 8 )

Two of the methods are about the network adapter.

I would try the specific troubleshooting for the network adapter first.

You might have to scroll down a list to find it.

Don't mix it up with the "network connections" troubleshoot which you already have done to no avail.

Don't forget the restart.

Second method I would try is brute force, uninstall network adapter and restart.

 

After that do your own search: "windows wifi yellow triangle" and good luck

You got to remember that from about 3 30 pm all the kids turn out of school and the first thing they do is to open the internet and jabber to their friends until about 8 30 pm when the signal strength seems to get a bit better

If I wish to do any serious downloading its got to be AM

The thread is not about slow internet or the like but an erroneous behavior of Windows.

Nothing specific to Thailand.

Just do the search and see the 6 million hits.

It sounds like a local IP address conflict, or a DNS issue? Obviously, restart the afflicted PC.

 

You can click on the network icon and then run the network troubleshooter. That will sort out most typical problems.

 

Otherwise just use ipconfig /release, the ipconfig /renew.

 

 

Duplicate post removed.

 

I also had the same problem with True in Sattahip. After much complaining they sent someone out to check the line and they fixed something. It now works, but at less than half the speed as before. Off to the True store to try to get things back to what we had before.

Thanks for the suggestions.

I tried the link K.BenQ posted but naturally my settings menu differed so difficult to follow path.  did try the "Troubleshooter" but it could detect nothing wrong.

Decided to try a system restore back to a date prior to the problem.  That worked in that I got my internet connection back but now I can't open Chrome. I can open and use Edge

One mystery solved, new one in it's place.
