Unusual network problems are occurring.
Unusual network problems are occurring.
I'm feeling really stuck here. I'm pretty comfortable with technology, but this problem just keeps piling up. For about a year, my computer was connected directly to the gateway (a Centurylink C4000XG via Ethernet). Suddenly it stopped working completely—no internet at all. I can still use Wi-Fi, and I’m used to being a bit of a tech mess. Even though I’m only a few feet away from the router, I got really slow speeds. Then it just shut down. It’s been over a year now, and neither Wi-Fi nor Ethernet is connecting to that gateway. I’ve tried everything: I plugged in my own router, tested both 5GHz and 2.4GHz, and even ran through all the troubleshooting steps. I even swapped out the Wi-Fi card and got internet again. But then I noticed my desktop connects fine with both networks, while I can’t reach anything outside. I’ve cycled the router a million times, updated drivers, flushed DNS, used the network troubleshooter, and everything else on the list. Still nothing. Now I see other devices connect just fine, but I’m stuck here. I’ve tried everything I could think of. What should I do next? Should I give up and set up two separate Wi-Fi networks inside my house? Why does it seem like only one device is having trouble?
It's the computer I assembled myself. I replaced the Wi-Fi cards, removed any files that might interfere with software, and performed a fresh Windows install, which should have resolved the issues.
It’s easier to fix at least some issues. Did you install all your chipset and LAN drivers from the motherboard manufacturer? Another test is to boot from a Linux USB installer (like Ubuntu) and check connectivity. It could be a Windows problem caused by an update that broke several systems, though it seems unlikely that two faulty Wi-Fi cards would cause this. Good luck!
