Ethernet Problems

Sun Mar 10, 2019 8:53 pm

I used an ethernet cable for my pc before, and when I was out of town, my family said that we were some how short circuited or something like that. Our neighborhood's transformer got struck by lightning or something. Either way, the ethernet connection doesn't work. I'll plug my pc to the router via ethernet cable, and it won't recognize that it's plugged in. Is there a way to get another ethernet plug besides the onboard plug?

I'll assume the cable and router itself aren't broken.

Newegg lists "network adapters" starting at $ 7 US. You'll want an adapter with an actual Ethernet connection, of course, not a wireless adapter.

Yep, network adapter or network interface card (wired NIC - the more precise term). Ethernet LAN is a common vector for lightning-based component death. Some people in thunderstorm-prone areas put in a fiber isolation gap.
Be careful on inserting this (or any G34 chip) into the socket. Once you pull that restraining lever, it is either a good install or a piece of silicon jewelry.

Your choices here are a PCIe (or PCI if this is a really old PC) network adapter card, or a USB Ethernet adapter. USB is easier since you don't need to install an internal card, but will limit your network speed if your PC only has USB 2.0 ports. If you have USB 3.0 ports (and get a USB 3.0 Ethernet adapter), performance should be pretty close to that of an internal card.

USB 3.0: https://www.amazon.com/AmazonBasics-100 ... 00M77HMU0/

Before buying a new adapter for the PC, you ought to make sure the problem isn't on the router side. Can you plug another PC or laptop into the router port to make sure it is functional? (If testing with a laptop, make sure the laptop's WiFi is disabled to ensure you're really testing the wired port.)
Nostalgia isn't what it used to be.
