Windows 10: Can't get connected to internet via ethernet cable.

All of a sudden my PC won't connect to the internet via a wired ethernet connection, the option isn't even available?

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

 

Cannot connect to Internet via direct Ethernet cable connection.

Hello. Have had this PC for about a year now. Came as Win7, updated to Win10 shortly thereafter. It is incapable of connecting to Internet wirelessly, so I connected it to modem directly through Ethernet cable. Have never had any problems whatsoever with
connectivity to the Internet.

All of the sudden, as of about last week, I would start up my PC and it would be disconnected from the Internet. It cannot detect any sort of Internet connections despite being directly connected to the modem. Even wirelessly connected devices in my home
like smartphones and tablets were unaffected by whatever ails my PC/Ethernet cable/etc.. I had:

• Restarted PC
• Unplugged and replugged in modem after 30 seconds
• Uninstalled drivers
• Checked for driver updates (of which there were none)
• Switched Ethernet ports
• Switched Ethernet cables
• Turned off firewalls and other malware-detecting programs
• Reset network devices
• ...and a host of other troubleshooting tips I have now forgotten

None of these worked, but after 10-20 minutes, the Internet returned to normal. It has just happened again, and I did not retry any of the aforementioned actions, and, once again, it returned after 10-20 minutes.

It may seem to be a very trivial problem if the Internet ultimately comes back, but this effectively means my PC's startup time is extended to about 20 minutes, and this proves to be extremely inconvenient when I need to access the Internet.

Please offer any suggestions you think would solve this problem. Whatever system specifications are needed I will provide.

 

Computer not recognizing Ethernet cable

Hi Vijay, I appreciate your help.

I will try each step even if I've already done it, just to make sure, and post my results.

A. When I troubleshoot internet connections, it tells me “Plug an ethernet cable into this computer” and says my cable might be broken or disconnected. However of course i have tried a different working cable with no luck.

when I troubleshoot network adapter, it says “plug an Ethernet cable into the network adapter ‘Ethernet’” which of course has already been done so it is not recognizing it.

B. I tried every suggestion/step listed (except for the wifi troubleshooting since my computer doesn't have wifi) and none of them worked.

C. When I run the windows update troubleshooter, it tells me “download and install pending updates” (Maybe it is not up to date because I tried reinstalling windows 10 to see if that would fix the internet, but it did not. I updated it like last week or
something like that) but of course I can't download the updates without internet. If I click “apply this fix” it tells me to plug in an Ethernet cable. But i believe windows 10 was up to date before this issue even began because I updated it just a week ago.

D. I do not understand this step. The guide is confusing to me. It also appears that I have to download tools in order to do this repair. I cannot download anything because my computer cannot connect to the internet. I don't have a USB flashdrive. I did
try reinstalling Windows 10 though and it did not help.
