I’ve been having trouble trying to get a hardwired ethernet connection with my HP Pavilion desktop since I moved to South Carolina from North Carolina in February, 2021. I had a dual-band Netgear Nighthawk router before my last move and there was no problem with internet intermittency, let alone a dead hardwired ethernet connection in my new home. I upgraded to a tri-band Netgear Nighthawk router (R8000/AC3200) last year and took care of the buffering issues on Netflix, but there was still the internet intermittency with my HP computers. A message still pops up saying “Hmm…We’re having trouble finding that site…Try again”, which eventually loads after several clicks, but it shouldn’t do that. Our mobile devices include: an android phone, a MacMini (2011), an iphone, two ipads and a Roku, all of which do not have internet intermittency or wi-fi issues of any kind. I never had any internet intermittency or ethernet connection interruptions in my NC home. It all started to happen the moment I moved here to SC. Other technicians have suggested an ethernet adapter, which will be my next troubleshooting step, followed by a portable router/hotspot to see if that takes care of the problem. Our neighbor next door has solar panels and its box is right next to my hardwired computer, but I don’t know if that’s creating any kind of intermittency in the signal.
I contacted Spectrum (my ISP) to come and check out the issue. The first technician that came picked up that the internet signal intensity was 38.5 dBmv, so he tweaked it down by adding a splitter on the circuit panel, but that still didn’t solve the problem. I then asked for a new Spectrum cable modem and they gave me a Hitron, but that didn’t fix the issue either.
I then bought another HP desktop (Win11, Intel Core 10th Gen) about 18 days ago to see if that would take care of the problem, but it didn’t. I tested connecting the ethernet cable from the modem to this PC and disconnecting the router to see if I got a hardwired connection with this new computer, but strangely, I didn’t. Today I tested my MacMini by doing a hardwired ethernet connection and disconnecting the router, and it worked flawlessly. But what puzzles me is that there were no intermittency issues in my previous home with the oldest HP desktop. It can’t be the Nighthawk Tri-band router because it’s a year old and it works awesomely. Has anyone had this issue? What do you think the problem is? Is it the cable modem? Th
