I am trying to connect internet and my corporations network at the same time,I am using one ethernet cable,and one ethernet to usb adapter,and using ubuntu 14.04.

Whenever I try to plug my ethernet cable,the network on the adapter starts not responding.

Here is my route table :

```
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref          Use Iface
    default         192.168.2.1     0.0.0.0         UG    0      0        0 eth1
    192.168.2.0     *               255.255.255.0   U     1      0        0 eth1
    192.168.122.0   *               255.255.255.0   U     0      0        0 virbr0

```

and this is my route table after plugging ethernet cable:

```
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    default         10.108.80.1     0.0.0.0         UG    0      0        0 eth0
    10.108.80.0     *               255.255.240.0   U     1      0        0 eth0
    192.168.2.0     *               255.255.255.0   U     1      0        0 eth1
    192.168.122.0   *               255.255.255.0   U     0      0        0 virbr0

```
