Toddler Naruto 26 Posted April 14, 2015 Does anyone here know why our PC loses internet connection when I plug the ethernet cable into our Xfinity Wireless Gateway?The Wi-Fi does work, and when the Comcast technician connected his laptop to our internet via ethernet, he got impressive speeds.System Info:PC Model: HP 110-326 DesktopOS: Windows 8.1 64-bitCPU: Intel Pentium G2030T @ 2.60 GHzRAM: 4.0 GBVideo: Intel HD GraphicsHDD: 500 GB Quote Share this post Link to post Share on other sites
Psychic_Ketchup 367 Posted April 14, 2015 I had a router that kept losing connection, and when nothing worked, I just stuck the ethernet cable directly in my pc (skipping the router). I know that's a bad solution, but hey. If your router works one time and it doesn't another, it might be faulty. Quote Share this post Link to post Share on other sites
OmegaForte 1,674 Posted April 14, 2015 Maybe the PC's wifi settings is set to conserve energy? I believe you have to go to devices to find that option iirc. I remember a few years back my PC would lose connection and apparently it was due to that. It would shut on and off, even though the notification symbol indicated otherwise. If not, the router is most likely failing. Quote Share this post Link to post Share on other sites
Dracozombie 4,554 Posted April 14, 2015 Okay, so, wi-fi works and ethernet works. Are they working at the same time, or can you only do one or the other? i.e. use ethernet, get no wi-fi, or use wi-fi, get no ethernet. What did the tech say about the problem?

VisitJoan 2,713 Posted April 15, 2015 Do you have Xfinity as a cable and phone provider as well? I know with AT&T, they lowered our internet speed to the point where it was useless untill we switched to Uverse. Maybe Comcast does the same thing?

Toddler Naruto 26 Posted April 15, 2015 We only have our Xfinity Wireless Gateway, which is both a modem and a router. I want to get the ethernet connection working, don't want the wifi running. Quote Share this post Link to post Share on other sites
Paranoia 494 Posted April 15, 2015 How old is the modem? if it's older than 4-5 years, then it might be at the end of it's lifecycle. Quote Share this post Link to post Share on other sites
Toddler Naruto 26 Posted April 16, 2015 How old is the modem? if it's older than 4-5 years, then it might be at the end of it's lifecycle. Modem is brand new, Comcast guy gave it to us. Quote Share this post Link to post Share on other sites
Toddler Naruto 26 Posted May 21, 2015 (edited) I went ahead and bought an USB 2.0 Wired Ethernet Network adapter, so far it's working perfectly. Heck, my connection actually improved from 6 mBps to 8 mBps after I switched from wi-fi to ethernet.I would still like to fix the PC's built-in Ethernet Network Adapter though, so I don't have to rely on the USB Adapter.
