is not the reason why she doesn't have internet. Is it blinking regular? What about the other lights? receive and send, are they blue? The online and power should be green. If all these are working properly then the problem, I think, is in the computer itself. As far as the 10/100 go, you said your services is 50mbps, the card is plenty capable.
Oh I almost forget. Did the problem started with win10. If so, you need to reinstall the LAN driver. This happen to me on one of my upgraded computer also.
A while back I and my sister bought our own “cable modems” so that we wouldn't have to pay Time Warner Cable their monthly fee. It's called a 'surfboard SB6141' DOCSIS 3.0 CABLE MODEM. Right away I noticed that her “link” light was blinking “amber”, which indicated that, I came to find out, that the Ethernet was 10/100 on her Compaq-Presario computer. My “link” light was blinking “blue”, which indicated that the Ethernet was 10/100/1000 on my Dell 3647 computer. Since we could connect without issue, we didn't worry about it. We're both using our computers for normal basic 'home' stuff.
First question, is what I just stated, correct? The 10/100 thing vs 10/100/1000. And if that is correct, nothing can be done unless you buy something or get the computer modified? Or is this a Time Warner issue? In the past, I would run a “Belarc Advisor” report and it would 'show' this 10/100 – 10/100/1000 thing on our respective computers. I updated both computers to windows 10 during the first week of August and ran a Belarc Advisor 'report then'. I now see that neither computer “report” shows this “10/100 or 10/100/1000 thing. Maybe minor point, her computer was a windows 7 and mine was windows 8.1.
So, my sister called today and said that she had no “Internet” connection. And, by chance, a Time Warner Cable “rep” dropped by. And from “her” point of view, there must be a major issue because the “link” light is “amber”. In the past, I would simply turn the computer off, unplug the power cord to the cable modem, wait a minute, power up the cable modem, wait till all “lights” were on, turn the computer back on, and the issue would be resolved, internet connection would be re-established.
The TWC rep left without fixing the internet connection issue, and plans on returning on Friday. So, I'm guessing the issue might be more serious, unless “she” just got hung-up on this “amber” light thing. I'm looking for any suggestions that might fix her computer. Hopefully we don't need to buy a new 'cable modem'. On a related note, what report could I run, or where can I look on the computer to see this “10/100” thing. I tried looking in 'device manager', but didn't see anything there.
Sorry for the long report and thanks in advance for any suggestions,
