Dropped Internet Connection - Bizarre Behavior

[paulbasel]

I have an Asus R500v notebook with a Windows 10 Home OS that has a wireless Internet connection to a router and has been functioning perfectly for the last few years.Two days ago it started to drop the IPv4 connection. The following is a description of the bizarre behavior.

I changed the adapter DNS settings from connect automatically to Google's DNS server settings. I use the Google DNS servers with my desktop and they work flawlessly. The notebook connected immediately without a restart. I shut down the notebook and after it was up and running again there was no Internet connection. I then deleted the Google DNS server settings and selected once again the DNS "connect automatically" option and voila, the Internet connection was restored. I have repeated this procedure about 5 times over the last two days and it is always the same.

- We have another notebook and it has a wireless connection to the same router as well so we know that it is not something to do with the router.
- No changes have been made to the computer, either hardware or software for the last few months.
- All scans with Malwarebytes and other software shows no viruses, PUPs or other malware.
- We have not moved the laptop. It is the same position in our office for the last two years.
- All adapter drivers are up to date and there are no issues showing in the device manager.
- After it reconnects it doesn't drop the connection until it is restarted.
- The Power Saving Mode is turned off on the wireless adapter.
- The notebook is always plugged into the AC.

Any ideas?

You can try this:

Open CMD with Administrator,
Type ipconfig /release. This will release your IP address.
Type ipconfig /renew to get a new IP address.


All this will do is release your old IP address, then give you a new one when you renew it, this can be a cause of quite a few issues sometimes.

This can also be shown as APIPA (Basically a private IP Address), read here for further information and a couple of extra tricks to attempt:

The notebook is being used right now, but I will run the commands you suggested this afternoon.

If I read the article on APIPA correctly it states that if you have other computers that are setup with DHCP and are networked together then you cannot use a private IP address. We have 3 computers in our network including this notebook so I don't think this is a good solution.

I couldn't get to the notebook until this morning. There was a large Windows update last night and after starting the computer this morning and the update was installed the Internet connection was functioning. I shut down and restarted and the computer connected with no problem. I'm still not convinced that it is "repaired" and if there are problems I will try your suggestions.

Many thanks for your help.
