Quesion PC isn't connecting because of a 1 Gigabit issue.
Hey guys, I've been having this problem on two computers now. They are stuck at 1000mbit and won't connect to a faster 1Gbit line. It's weird because every time I reset my PC, it gets the fast speed for a few hours or days before coming back down to 1000mbit. My setup is kind of messy but it works on another computer downstairs. We ran a LAN cable from my router through a hub and then into an outlet in my room, where that goes into my PC. I have a brand new motherboard for this one; it supports gigabit speeds just like the router and my old PC's motherboard. The switch lights up normally when a cable is plugged in, but not with mine. Even though I connected every other cable before, there was still only one light on. I tried the duplex and auto-negotiation settings, but that didn't help either. I bought a new CAT6 cable for my PC and it's still broken if you ask me why! If anyone has any tips or tricks to fix this, I would really appreciate it since I just don't know what to do anymore and don't want to wait forever until I get a new game xD. My specs are: Windows 11 with an Asus ROG Strix B550F Gaming (WiFi) mobo.
Whenever I try to do a hard reset on my PC, Can you walk me through what you did there? Hard reset means clearing the CMOS or resetting the OS? What's the BIOS version for your motherboard right now? For the sake of relevance, please mention the make and model of the router.
Well did you actually wipe out everything on your hard drive before putting Windows back up? Or did you just use an installation disk and start fresh without removing old data first? Basically, a factory reset only happens if someone restores a pre-built system to how the repair shop left it. Otherwise, when I'm trying to fix something wrong, people usually give better advice by showing me what steps they took instead of just calling them out on their actions.
Uhh well I just went into Windows Options and chose System, then clicked Reset. I deleted all my stuff and let Windows start fresh from scratch. Honestly, that's basically a factory reset. It means putting everything back to how it was before the computer turned on for the first time. The hard drives only have the operating system now; there are no personal files left except the system software. I hope you get what I'm saying.
So try the easy fix first. Put your PC close to the router and use a short cable, then plug it in there. This should stop the computer from being the problem. You might want to check the obvious settings and make sure the port is set to auto speed for the ethernet nic. Based on your description of the switch, I think your PC is only running at 100mbps. You can look at the manual for the switch to see what those lights mean. It probably has one bad cable. A bad cable might work on some machines but not others. This is especially true when there are so many fake ethernet cables being sold now. These fake cables don't meet standards, even though they look okay. Some devices can handle non-standard cables better than others. The 2.5 ports are less tolerant of bad cables because they try to test if the cable supports 2.5g speeds too. A perfectly good cable could still fail just from age or wear and tear. All it takes is one wire getting a little loose at the end or a small crack in it, and that breaks the connection. You only need cat5e cables, but they have to be made of pure copper (no CCA) and use wire sizes 22-24 gauge (you can't see flat or thin wires everywhere). It is easier just to buy new cables for the ones you have access to. Your wall plugs are harder to replace though. Luckily, it's almost never the actual wire that fails; usually it's one of the ends. I would take off the wall plate and look at the wire closely. Maybe a wire has come loose. Also check if the color pattern looks right. If you really want to make sure, remove the wires one by one, cut a tiny bit off each piece, push them back into the jack, and see if it works. You can also buy replacement keystone connectors that go into most wall plates if the jack itself was damaged.
You are very welcome! I'll definitely give it a try. If it works out, I'll tell you right away with a happy smiley face 😊
