I live in an apartment where I rely on a WiFi extender to get a solid signal in my bedroom for my home office. My PC doesn't have built-in WiFi, so I connect it to the extender with a LAN cable, which has worked great for over five years. Suddenly, this stopped working last night! My PC shows it's connected to the home network, but there's no internet access. Meanwhile, all my other devices connected via WiFi are working just fine. I've tried several troubleshooting steps including rebooting both the router and extender, disabling DHCP and manually entering the IP address, pinging devices successfully, replacing the LAN cable, and updating the network drivers. I suspect it might be a DNS issue but can't seem to find a solution. Can anyone help me figure out whether this is a hardware or software problem? Specifications: PC - Windows Desktop, Router - Netgear R6700AX, Extender - TP Link RE230.

Try running "ipconfig /all" in the command prompt to see if your DNS server matches what you expect. That might help pinpoint the issue.
Honestly, WiFi extenders can be pretty unreliable. It might just have failed. Many of these devices don’t handle heat well, so components can give out after a while. I’d consider replacing it if the other suggestions don’t work.
Did you try doing a hard reset on your extender? Returning it to factory settings might resolve the problem.
When you're connected to the extender, can you ping other devices on your local network? It might also help to try plugging another device into the extender via Ethernet to check if it gets internet access. If it works, you could connect your PC directly to the router using a long Ethernet cable to rule out any issues with the extender itself.
