I have a lenovo y50. I started up m y computer and it didn't connect to the internet. I looked in network connections, and my nic was not there. I then looked in device manager, and under network adapters there was only my intel wireless 3160 and virtualbox adapter. I checked in the bios and there was a option to enable/disable wireless network but not wired network. Thanks in advance and please help.
Hmmm... I found a manual 2 manuals online. One tells how to take apart my laptop, and the other one tells how to use windows 8.1. Very helpful. There is also a bios update on the lenovo website. Should I install that?
now it shows up in device manager as nic, it also shows up in network connections. But now when it just says identifying instead .of my network name. Then it says unidentified network and it has it as a limited connection. When I use troubleshooter it says. "Ethernet" does not have a valid IP configuration.
So you got your NIC detected and installed, good, as for the IP assignment some routers apply their DHCP only on their wireless clients and not via wired ones, either enter the router and look if there's an option to enable DHCP on LAN clients (or maybe on LAN ports 1 to x) or set an static IP in the same network your router is, i.e. if router is 192.168.0.1 try using the following values:
IP address: 192.168.0.55
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server: 220.127.116.11
