Assisted two neighbors today that (during the past several days) lost their internet connectivity. One box was hard wired and the other was wireless. Both situations, which I eventually resolved, has me wondering what broke the connection. I am thinking a Windows update, but not even sure on that. I ruled out malware in both cases; but who knows, may have been something in the wild. It may be a coincidence, but both computers experienced the same exact issue. One box was Windows 8 and the other Windows 10. After checking the modems, routers and cabling; determined the issue was occurring at the computer level. Reboots often will resolve problems (such as power management issues); however, in these two cases, the magic of a reboot did not work to resolve the problem. It was after running the ping commands and the ipconfig commands from the Admin Command Prompt that I determined the issue (in both cases) was at the network adapter level. In both instances the properties of the network adapters (in the device manager) displayed that the adapters were working properly. I was also thinking possible Winsock issues where the TCP/IP needed reset. Anyhow, while I was in the network card adapter properties, I clicked on the “driver’s tab” and clicked on “update driver” knowing it would be impossible to update the driver from the internet (due to no internet connection). The driver update failed, but guess what, the internet connection in both cases immediately came back to life.
I am not an everyday tech, as I once was years ago, and I am puzzled over this. If you have any insight to this, please leave a comment that may be helpful to myself and especially to others. Thank you…

What is the CompTIA Troubleshooting Theory? The theory consists of six systematic steps that you follow to effectively identify a computer problem. It is important that you stick to the steps in the order as listed.
By following these steps you eliminate jumping around and wasting hours on a problem. You may find that once you have exhausted all avenues, to the best of your abilities (and knowledge), that it is time to take the problem to another person (or higher technical level) for possible resolution.
It is best practices to always maintain a document trail of your findings so that in the future you are better prepared to effectively deal with future problems.
The six CompTIA Troubleshooting (Theory) Steps are:
- Identify the problem – Question the user and identify user changes to computer and perform backups before making changes.
- Establish a theory of probable cause – Question the obvious.
- Test the theory to determine cause – Once the theory is confirmed, determine the next steps to resolve problem. If the theory is not confirmed, establish a new theory or escalate.
- Act – Establish a plan of action to resolve the problem and implement the solution.
- Test and prevent – Verify full system functionality and, if applicable, implement preventative measures.
- Report – Document findings, actions, and outcomes.
Here is a nice video on the Explanation of Troubleshooting Theory:

Just when I think I have found most of the golden nuggets on the internet, I come across another. While performing an update to the Bookmarks4Techs listing, a visitor to the site contacted me and suggested that I add the tech site GEGeek – PC Tech Quick Reference to the listing.
What I expected to find was a tech blog, but what I came across is a Geek’s paradise for anyone who is into computers; and especially, computer repair & troubleshooting. While you are there, pay special attention to the GEGeek Tech Toolkit. This toolkit should be called a Tech Tool Shop… It is a 1.0 gig download and contains everything, as a tech, you would ever need.
An excerpt about the author of GEGeek:
This site is the culmination of years of CAREFULLY selecting a handful of links to assist me on my current job, personal consulting work and of course my own PCs. Not every site has all useful links ⁄ articles, but there were always one or two gems to be found on every site I visited. Keeping them readily available and manageable became quite a chore, so i created this site just to help me organize them and provide a quick reference . The “How To” is assumed knowledge, I just provide the quick reference.
