ipv4

I get my internet connection from a guy (lets call him my service provider henceforth). He gives internet connections to many students here in my hostel. My PC gets a private IP through his DHCP server. Now, when I switch on my WiFi, my PC gets a private IP as it should and I can connect to the internet just fine. But now when I connect my LAN cable, my PC gets some "Autoconfiguration IPv4 address" 169.254.110.154(Preferred) and I cannot connect to the internet. Here is the ipconfig /all output for ethernet port:

Ethernet adapter Local Area Connection:

I also tried:

Start a command prompt as admin.
Run "netsh winsock reset"
Run "netsh interface ipv4 reset"
Run "netsh interface ipv6 reset"
Restart your computer.

All this does not work. Any idea to solve the problem?
