My Wi-Fi is broken again after my computer turned itself off for no reason.
My Wi-Fi is broken again after my computer turned itself off for no reason.
I was watching a youtube video when my PC decided to turn itself off and back on again. When it came back up with Windows 10, I had no internet connection because the wired line was cut. I'm not sure what extra steps I need to take so I can add them below. Here is how I tried to fix this problem (I did this many times in different orders): Cycled the modem and router Checked for updates on my router Removed the driver from my network card, installed it back, then tried updating it from my motherboard maker's site Cleaned out Windows completely Updated my motherboard BIOS I plugged a brand new Cat7 cable into everything. I plugged the PC straight into the modem to skip the router entirely. I ran all those net commands to reset winsock, flush DNS, release my IP, and renew it. I tried every troubleshooting tool that came with Windows 10. The results are this: (My default gateway is missing, Ethernet has no valid IP address). It keeps switching back and forth between the two things. Every other device both wired and wireless still works fine. Even though I bypassed the router completely and used a new cable so it feels like the problem is on my PC itself, I don't have an external NIC card to test if the motherboard's built-in network adapter is broken.

Do I need a power supply? If this one is bad or low quality, it might be breaking things down randomly.
Not having a wired connection can mean different things. Check if the Ethernet shows up in your Device Manager. If it doesn't, something is probably broken inside your hardware. If it does show up, are there any warning signs about drivers? Maybe Windows figured out how to fix them already. Open IPCONFIG /all to see exactly where the Ethernet port is connected or disconnected. Does it have a status that tells you if you're getting an IP address or not? Remember those random 169.x.x.x addresses that come up when your computer can't find a real one?
It's a Thermaltake Smart 650W 80 Plus. Probably had it about 2.5years now, that's not to say it couldn't go bad for whatever reason. I will keep that in mind though.
Your ethernet adapter shows up in Device Manager and looks like it's working fine. But here are some important things: You can't connect to the internet because there is no actual internet connection, even though your device says it is connected. Some settings are turned off for IPv6 (like getting a private address automatically). There also is no DNS server to look up websites on the network. When you try to get an IP address via DHCP, it gets set to 169.x.x.x instead of a normal number. Also, there is a NetBIOS setting that might not be needed for your home network.
This all means your computer didn't get an IP address from the router. It could be because of the DHCP settings. The quick fix is to change the network settings and set a static IP instead. If your router uses addresses starting with 192.168.x, you probably should use 192.168.x.250. Routers usually give out the lowest numbers first, so if that doesn't work, you might need to fix something wrong with the DHCP setting on your router. If you can't figure it out yourself, just set a static IP address and see what happens. Even worse is if it still won't connect, then there could be a hardware problem in your setup. I had some of my ethernet ports broken by lightning and they looked okay but couldn't send or receive any data. Make sure you aren't plugging the PC into a switch that isn't connected to the main router either.
Right, I don't know what I should do if this were something silly. I have been working on this for almost eight hours straight. I thought about saying that I tried plugging the computer directly into the modem to skip all those steps without any luck yet. I will try setting a static IP address... would it just be changing the IP, or do I need to add anything else? I think I have set everything up correctly. Still no luck; all the information is showing in ipconfig. But I can't see the PC on the network map of the router.
