Hi I have a brand new Dell Inspiron 5748. It was working fine for about a month, but now there seems to be a problem with my ethernet. Specifically, the Local Area Connection keeps saying the network cable is unplugged, when it's plugged in. I know it's not a problem with my ethernet cable because it works fine on my old laptop and my roommate's ethernet cable didn't work on the new laptop either. What's weird is that when I set the Speed to 10 mbps full duplex, the internet works fine. But I don't think it's right that a new laptop has to run at slow internet from now on.
I have a Realtek PCIe FE Family controller driver version 7.89.716.2014, i've tried uninstalling/reinstalling the driver, doing a system restore, running the internet in safe mode, running malware bytes to make sure it's not a spyware problem, and tried all the windows updates, still no avail.
I've also tried turning off my computer and taking out the battery for a while then putting it back in and turning my computer on. Still nothing.
