Windows 10: Ethernet connected with Internet access, but not getting internet

Ethernet connected with Internet access, but not getting internet. Only internetworking with Wifi

No internet after connecting Home AV system Ethernet cable

Dell XPS8900 Desktop System works fine, then I connect the Ethernet from the PC to the new Home HiFi AV system (via Sonos S-Connect) After that I get no access to the internet. If I disconnect the Ethernet cable (and reboot?) I get internet again. If I
connect the Ethernet cable after first establishing access to the internet, I get internet AND control of the Home HiFi AV system until the PC goes to sleep or is turned off, then no internet again. Any suggestions please. Regards

 

Internet Connectivity Issues

So heres the deal. My brother who is behind the opposite wall of me is having internet issues. The router is here in my room and his internet is plugged into the Linksys E2000 via a wire going from it to an ethernet wall socket going to his room and into his computer.

He has been having iffy internet for the past 2 days. Fixed it yesterday by rebooting now the problem has resurfaced.

What we have tried:

• Testing the ethernet cables with a tester. Passed
• Tested onboard ethernet with known working cable (computer hooked up using my connections in my room) Passed
• Checked to make sure there was no static IP address in IPv4 settings. Passed
• Made sure the Network Connection wasnt full on disabled. Passed
• Swapped the cable leading from the router to the wall outlet in my room. Passed and worked for a few minutes.

With regards to that last bullet point, the computer is no longer getting internet again despite working for a few minutes. Testing the new cable again, tells us that pins 1 and 2 are "open". That is the second cable in a row that the tester is spitting this message out on.

Any ideas guys? Im out of them.

 

Internet Slowdown on my Desktop - Ethernet Connection

Thanks Vijay. I went through your steps other than the repair upgrade, and there was no change. Before I do the repair upgrade, I want to check on another angle.

I went into Networks and Sharing and realized that Windows is simply not recognizing my Verizon modem/router as the Ethernet connection. The slow internet access is due to the fact that the desktop is picking up the WiFi signal, and it's not strong on this
device.

For Ethernet, I get an "Unidentified Network" and when I click on Ethernet Status, the IPv4 and IPv6 connectivity lists "no network access". Looking at the Ethernet properties, the "Connect Using" lists Realtek PCle GBE Family Controller. Shouldn't it
be the Verizon modem name? Also noticed that the Microsoft Network Adaptor Multiplexor Protocol is unchecked. Not sure if that matters.

I think what I need to do is somehow configure the Verizon modem again, but not sure how.
