Windows 10: Ethernet - Internet not recognized when reconnecting

I have a w10 desktop, set up 2 internet connections - 1 main ethernet and 1 wifi adaptor which is connected to an EE dongle for use as a back-up connection. Windows obviously defaults to ethernet and then when I pull the ethernet out to replicate issue with the line it switches automatically to the wifi connection in my case the EE dongle. which is great and what I wantHowever, when I plug the ethernet back in to replicate if line is back on etc it recognizes that it is there but just say unable to connect to internet. Is there a fix to this?On rebooting it connects no problem,

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.

 

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.

 

Ethernet cable getting recognized only after uninstalling and re-installing the ethernet driver

Hello all. I have a laptop which came with Windows 11 installed. At first there were no issues but for the past week my Ethernet cable does not get recognized by my laptop. Following the steps I have seen here in similar questions, I unplug my cable, uninstall the Ethernet driver from the Device Manager, Scan for hardware changes (driver gets installed automatically), plug the Ethernet cable and everything works fine. Next time I open my computer the Ethernet might or might not get recognized. I have to do this task almost every time I open my computer. Any suggestions?
