I've looked through other posts with similar issues but so far to no avail. I'm running dual boot with Windows 7 and Ubuntu 15.10 and although the Ethernet connection works on Windows, when I boot Ubuntu it works for a few seconds and then the connection drops. I don't get any notification saying I've been disconnected and the symbol remains the up/down arrows. When I try pinging to a host like Google no host is found. I've disabled Wi-Fi on Ubuntu and tried unplugging/replugging and I get the same issue with working for a few seconds then losing connection.When I run ifconfig -a I getenp2s0    Link encap:Ethernet  HWaddr dc:0e:a1:f5:60:20            inet addr:10.61.3.103  Bcast:10.61.3.255  Mask:255.255.255.0          inet6 addr: fe80::de0e:a1ff:fef5:6020/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:309 errors:0 dropped:0 overruns:0 frame:0          TX packets:109 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:42594 (42.5 KB)  TX bytes:13900 (13.9 KB)          Interrupt:16 lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0          inet6 addr: ::1/128 Scope:Host          UP LOOPBACK RUNNING  MTU:65536  Metric:1          RX packets:246 errors:0 dropped:0 overruns:0 frame:0          TX packets:246 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0           RX bytes:22223 (22.2 KB)  TX bytes:22223 (22.2 KB)wlp3s0    Link encap:Ethernet  HWaddr 9c:4e:36:17:1f:44            BROADCAST MULTICAST  MTU:1500  Metric:1          RX packets:0 errors:0 dropped:0 overruns:0 frame:0          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)And when I run netstat -rn I getDestination     Gateway         Genmask         Flags   MSS Window  irtt Iface0.0.0.0         10.61.3.1       0.0.0.0         UG        0 0          0 enp2s010.61.3.0       0.0.0.0         255.255.255.0   U         0 0          0 enp2s0169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 enp2s0I also tried running sudo arp-scan -I enp2s0 -l to look for duplicate addresses and found none.I'm still very new to Linux and some network terminologies but any help would be appreciated.Also to note that the Wi-Fi connection works just fine. It's just the wired connection that is having problems.
Ubuntu ethernet connection works for few seconds then drops (with Win 7 dual boot)
