I have a very specific problem that involves a specific desktop computer and a specific ethernet wall connector. I have already tried several different approaches to solve the problem, so read this post carefully as I describe them.
I have a desktop computer (specifications at the end of this post) connected to an ethernet wall connector in my condo. A couple of days ago, I noticed that the Internet was periodically cutting off for a short period of time. This was first noticed as a loss of video quality during transmission, but it also manifests itself as longer initial connection times when the computer is first turned on, periodic changes in the network status icon and disconnection of Online games
Of course, my first approach was to try changing the Ethernet cable for a different one. This did not correct the problem.
Then, I made sure that all of my unit's Wi-Fi connections, such as those on my mobile devices, function normally. There are no problems with the WiFi.
Then, I tried to connect my work laptop to the same connector that the desktop machine was using. I disabled WiFi connectivity to the laptop, to prevent it from changing, if it loses the signal. However, there were no problems with using the laptop on the same connector that the desktop machine was using.
I have a second wall socket in the area of my home office, so I tried to take the mechanized desk there and plug it into that socket. Here it is where it gets interesting. The desktop machine had no problems executing that connector. In fact, I was able to play in the online game for a significant period of time, without interruption. Okay, the monitor in my home office area is not HD, so download bandwidth requirements may have been reduced. However, they would still have been important, and when it was connected to the first connector, it still had problems, even when there were no active user programs.
I tried to leave the laptop running on the first connector and the desktop running on the second connector, to see if the Windows Event Viewer detected disconnections, but none was received on any of the machines.
Finally, given the possibility that the problem was a power fluctuation, I tried to plug the laptop into the first connector and run the power from the same power bar as the desktop computer, with the mechanized desk and its peripherals (speakers , external sound amplifier, monitor) all running at the same time. Even so, the Event Viewer did not detect connectivity problems with the laptop using the first connector, nor did it change to battery power.
In summary, this problem ONLY occurs with the desktop computer and ONLY It happens with that specific jack.
This puts me in a kind of Catch-22. I can't take the desk to the store (it's still under warranty) and say something is wrong with the ethernet card because they will point out that it works fine on another connector. I can't call my ISP because they will point out that the WiFi is working, as well as the first connector with a laptop and the second connector with both computers. I can't make my building see it because they will point out that the connector works well with the laptop.
Any suggestions will be appreciated. The specifications follow.
