Question on network drops, attempted all solutions including EMI issues.
As discussed, moving the PC closer isn't feasible. However, a voltage issue seems more likely, possibly due to the onboard Realtek NIC versus the Intel NIC I purchased. Changing the wall jack isn't an option, but if the problem is voltage-related, it might resolve with a new cable for a short period. In the HWMonitor, the auxpin 0 was reading 78°C, though some claim it's just a software glitch to overlook. Would you consider using unshielded cables? Should I opt for a lower MHz Cat5 instead of Cat8 to reduce DC susceptibility? There are many factors here, and I'm trying to figure things out now. Also, is it better to use the cable inside the wall or not?
It is very probable that the cat8 cable is not genuine unless you exceeded $50 for a 2 meter length. Authentic cat8 cables are offered by specialized network equipment suppliers. The price of these cables is only relevant to companies that can afford the necessary switches and hardware capable of handling 40gbit speeds.
The cable itself lacks features like MHz rating, voltage, amperage, or any technical specifications. It consists solely of copper wire encased in plastic. The actual devices generate the signals. As long as the cable supports the required MHz range, the ports will function properly. The capability to handle higher MHz does not change this—it simply indicates that if your ports needed more bandwidth, they would also support it. However, since you are only using 1gbit, there is no need for cat6a or cat8, which operate at 10gbit and 40gbit respectively.
Having tested several cables rated for 1gbit, it seems unnecessary to purchase additional ones. It is unlikely that a defective cable was the issue, so buying more won’t help. If you decide to buy new cables in the future, opting for simpler models like cat5e or cat6 would be more cost-effective. The cables you currently own appear to be in good condition; you merely overspent on them.
This behavior is not due to a software glitch. If the ports fail to connect properly, it is because the hardware determines speed and connectivity through the Ethernet chips themselves. There are no firmware updates or software changes involved.
I misunderstood your comment about a software issue. Hwmonitor cannot determine the condition of the Ethernet chip. These chips can overheat without any cooling solutions.
software bug, everyone got the same results and they all say it doesn't measure well enough. So at the end of the day, what can I do? I bought a lot of cables, now unused, but I keep wondering why everything works fine for a few days when buying new ones. I noticed this pattern three times—always the same issue. The more days pass, the more DCS starts with one or two, etc. What should I do? And regarding fake cables, I know about the Cat 8 and 7 fakes, but even the more expensive Monoprice ones still had disconnections. The Ugreen brand failed right away, while KableDirect and CableMatters were available on Amazon for a few days without problems. It really bothers me because I've been dealing with this problem since April as I mentioned before.
Essentially, the only thing you haven't attempted is the in-wall cabling. You've replaced all the existing cabling and even tried a different type. I think you also checked another port on the switch just in case that was faulty. That means the in-wall cabling is probably the issue. Fortunately, it seems unlikely the wire itself is the problem, but more likely one of the connections.
Yes, tried different ports. Okay, so if only this thing is left I will try to do something about it. Anyways thanks for help for now.
Also overlooked was an electrician a few months back who checked the voltage in the house. Everything seemed fine, but could the wall jack still be damaged?
Ethernet cables operate separately from electrical wires. You've likely changed all other components, which suggests the issue might be with the wall Ethernet connection or possibly defective replacement parts. There are costly test meters available to verify wall and other Ethernet cables, but it would be more economical to have someone install a new cable rather than purchase testing equipment.
I meant wall jacks and power sockets but thank you again for your help.
