Ethernet intermittently stops for about three seconds every fifteen seconds.
Ethernet intermittently stops for about three seconds every fifteen seconds.
I just returned from a week away and started using my computer again. When I tried to open something, loading took an extremely long time—ranging from 10 ms to 5k ms in seconds. It fluctuated up and down without progressing. I was playing games or doing nothing, and I switched between a 100 ft Ethernet cable and a 20 ft cable connected to my hallway extender. The problem persists; Wi-Fi is fine elsewhere but struggles in my room, currently at 1 bar. I ordered a new 100 ft Ethernet, but I’m unsure if that’s the cause or if the port on my computer has failed. Also, the internet works perfectly on another device. I’m on a 2GB up/down fiber plan. Please share your thoughts or any solutions you’ve found before—I really need help right now. Thank you.
What do the router LEDs indicate? Do they display a pattern similar to what you mentioned?
A steady ping to your router's IP address reveals whether the connection is stable or fluctuating.
A constant ping of 8.8.8.8 suggests a reliable and consistent network link.
Router LEDs display green across all connections. I contacted my ISP about any issues in my area, but they confirmed everything is functioning properly. I tested multiple times using pings to 8.8.8.8 and 4/10, which timed out on my Ethernet connection and also when pinging my own IP address. It seems the connection drops briefly before reconnecting. Without request timeouts, my average ping to my IP is 0ms, while 8.8.8.8 shows 11 ms.
If the ping to your router IP doesn't work, the issue lies within your home. You need to figure out whether the problem is with just your computer or the whole network. Do you have another wired device that can keep a steady ping to the router? This is the easiest check. Perhaps a laptop close to the router using a short cable.
I think it would also help to take off the Wi-Fi extender, in case it's interfering with your network during testing.
You're aiming for the simplest test possible—just your router, your suspected PC, and one cable. If you need to move your PC near the router for verification, do so.
I tried using another machine connected through Ethernet. It’s my previous computer, but it’s running smoothly without any lag. The tests passed completely, with an average ping of zero and no request timeouts.
Do you have both wired Ethernet and Wi-Fi active on the same computer, linked to the same network or router?
Yes, this setup leads to issues, as explained.
This phenomenon is known as a Network Loop.
According to the article, https://www.cbtnuggets.com/blog/technolo...twork-loop
If you're using wired Ethernet, ensure Wi-Fi is turned off.
I have checked another machine using Ethernet. It’s my previous computer but it’s running smoothly without any lag. The tests passed without failure, and the average ping to my IP is zero with no request timeouts. Wifi is turned off when using the wired connection. This problem began after I took a week off, returned home, and restarted the PC. I tried three different Ethernet cables and none of them resolved the issue.
Then it's just one PC. You must determine if the issue lies with hardware or software. The simplest test is to boot a portable Linux from a thumb drive. Check the ping of the router's IP address using Linux. If the results are consistent, the problem is likely software-related. You might need to reinstall the operating system to fix it.
There were a few storms, but everything in my house other than this computers internet is working perfectly fine with no cutting in and out, Currently waiting on another new ethernet cord to get delivered, if that didnt work, Was planning on buying the TP-Link 2.5gb lan card
