I should also add that while these problems were happening I woke one morning to find my internet completely out and a message saying that 'Killer Ethernet e2400 (or something like that) isn't responding.' Per online advice I uninstalled that software, but kept the 'Killer Wireless Drivers.' That 'fixed' the issue only in that instead of a completely dead internet connection it has returned to its normal state of working on and off. This is from the ipconfig/all during the last 'outage' while connected with Ethernet cable. My internet speed is 100 mbps (what I pay for), but speedtest usually registers 115-120 (for Ethernet, and just slightly less for WiFi) when everything is working. I'll try my wife's computer when I get the chance. (The technician also had me update the drivers, and disable WiFi on my PC while Ethernet cable was plugged in to make sure there wasn't a conflict there).

Why would my phone, or television, or my wife's phone and laptop lose WiFi when my Ethernet cable is plugged in on my computer, but not when it's unplugged? I understand that there might be a problem with the port on my PC (according to the technician), but I don't get why that would interfere with the wireless connection on other devices. So I'm wondering if anyone can help explain why this is happening. In the end I've determined that as long as my ethernet cable is plugged in I have connection problems (WiFi included and on multiple devices). Then it started happening again (constant dropped connections, long periods with no internet at all). He also had me change my Ethernet cable and that fixed my internet connectivity issues completely (wired and wireless) for about 1 hour. He found an old splitter on the exterior and replaced it, but otherwise he said their lines were good.

Nothing changed so I had the cable company send a technician. Recently it became so bad (and no advice from the internet would work) that I bought a new modem/router. I bought a new computer and it was fixed for about 2 years, but then it started again, exactly as before.

I've been having increasingly worse internet connectivity issues for a while now.
