Need assistance with unstable network connection.
Need assistance with unstable network connection.
Hello all, If I've posted this in the wrong location, sorry ahead of time. I'm going to try to be as thorough as possible, but if I missed anything please free to ask. I purchased a new PC 2~ weeks ago. It runs great, however the ethernet connection dies out randomly. It could be after 5 minutes, or 2 hours. It could work on boot, it could not work on boot. I updated the BIOS, chipset, and network adapter, no difference. I purchased a new ethernet cable, no difference. I contacted the manufacturer, and they walked me through the same steps I had already done. At the end, they said to bring it back to Costco and just exchange it, citing a bad ethernet port on the mobo. I did that, and the new computer has the same problem as the old computer. When the PC stops working, I unplug the ethernet, and plug it into an old laptop. The old laptop does fine. Neither of my old pieces of gear have had this issue. I also plugged in a USB-C to ethernet adapter, one which worked on my old laptop. It has the exact same issue on the new PC that the onboard has. Sometimes internet, sometimes not. Unplug/plug, sometimes fixes, sometimes not. Reboot sometimes helps, sometimes not. I'm really at a loss as to what to verify or test next. Some of the above testing makes me think it's the new computer. Some of the above testing makes me think it's something in my home network/wiring. Can the community suggest anything else for me to try? I was considering installing a PCI NIC but, I don't see how that would end up being different than USB-C/Ethernet I've already done. During the time it took me to write this, I connected to the internet using the onboard NIC. Part way through it died. So I moved the cable to the USB-C/Ethernet cable. After a while, that also died, and I am finishing this via wifi. Info: Computer IBuyPower Element Pro B650-VC WiFi Realtek Gaming 2.5GbE Family Controller, Driver 10.74.1128.2024 *** In writing this I see they came out with a new driver just a couple days ago. I'm going to install that now and see if that makes a difference. Though, I don't know why this would impact say the USB-C/Ethernet trail. Home setup: Ethernet from the switch on the main level, routed in the walls to the port on the wall in my office downstairs. I just ordered a 100ft cable so I can try just circumventing the cables in the walls. Though, said cables in the walls serviced a different desktop, and two other laptops over the years just fine. I don't know if it matters, but the WiFi has been fine.
Are your laptops or older gadgets using the same Ethernet cable for both 2.5GbE and regular gigabit speeds? The age of your router or switch might affect its compatibility with 2.5GbE. You may need to manually set ports to gigabit mode if it doesn’t support it, and disable auto-negotiation. I assume the USB-C to Ethernet port is gigabit, which seems unusual. Other possibilities include verifying your new PC has a static IP address, or checking if another device on the network is assigning its own IP. Also look at your DHCP range to ensure it isn’t full. Inspect your wall jack—perhaps you need a different keystone jack in your room. Finally, confirm the connection to your router or switch. Similar problems often require swapping physical connections inside the building after installing a new Ethernet cable.
The "old" laptop runs a 2.5 GHz processor (Killer E3100G 2.5). The other device uses gigabit speeds via USB-C/Ethernet, while the switch equipment is outdated but compatible with the older model. I'll try switching to gigabit mode and see if it helps. The DHCP setting is active, but the network range seems limited. I'm inspecting the keystone and wall cabling first. Once the long Ethernet cable arrives, I'll test it to bypass the current connections. This NIC might be more sensitive than the others due to poor connections. Please note my concerns about DNS logs and timing accuracy. Relocating the PC to a different network could be a workaround. Thanks for your help.
It seems like you're dealing with DNS issues. You might want to check your network settings using Wireshark. Alternatively, consider using trusted DNS servers like 8.8.8.8 or 1.1.1.1.
Ensure the router or network controller is set up and your personal devices are configured as well.
Interesting tidbit! In Australia, choosing 1.1.1.1 or 8.8.8.8 helps avoid the government-imposed limits on torrent sites. ... according to the tale.
