I am new to Linux. I recently installed Xubuntu. My computer is dual-booted with Windows 7 and Xubuntu running in the same machine. It works fine in every way. The internet in Xubuntu also worked fine. However, a few days back, due to a lightning strike, the internet port in the rear side of my CPU got damaged. The ethernet cable was operational, but due to internet port damage, I lost my internet connection.
I bought a usb 2.0 10/100M ethernet adapter (Kontron DM9601 fast ethernet adapter) and plugged the ethernet LAN cable into it. This adapter was then plugged into a USB port. After installing the right drivers and re-configuring the IP Addresses (the ones which were there before the port damage) in Windows 7, the internet seems to have returned and the Internet works well in Windows 7. However, when I restarted the machine and opened Xubuntu, there was disappointment ahead. Even when the adapter was plugged in, there was no internet connection in Xubuntu. I configured VPN > Created a new Ethernet Connection > Deleted the existing but unusable Ethernet Connection > Set the Mac Address > Set the IP Address, netmask, Gateway, DNS Server under IPv4 Settings> Saved and closed the Network Connections box.
However, even with all these efforts and many more, I am still unable to set up my Internet Connection in Xubuntu. It shows
Disconnected : you are now offline.
I ran the terminal and executed
$ lsusb

Bus 001 Device 005: ID 0fe6:9700 Kontron (Industrial Computer Source / ICS Advent) DM9601 Fast Ethernet AdapterI hope this is the info you asked for, chili555. Still no internet connection in Xubuntu.
I ran
sudo modprobe dm9601
in the terminal. The output just asked for my password and nothing else changed.
Code:
[sudo] password for subhankar:Next I typed
ifconfig
The output was

One thing I would like to mention is that, there is a feeble connection for a few seconds and then I am back to disconnected. The connection lasts for so short time that I cannot open any website with it.
Anyway, thanks for the reply, chili. Any further suggestion is welcome.
You may be right, chili. I was also getting a feeling that my 2 ethernet connections eth0 and eth2 were clashing against each other. But, I am at a loss on how to resolve this possible conflict.
On opening my Network Connections, both eth0 and eth2 are listed, but they are grayed out. Both of them are displayed as disconnected.
I opened the terminal and entered
lsmod
The output is a huge one. I am listing the output below.

mii 16384 3 dm9601,sr9700,usbnetThanks for your quick reply, chili. It was too late at night when I edited the previous post, that's why I couldnot reply to you earlier. I am sorry for that. Hope this result clears some clouds of obscurity. No internet in Xubuntu yet. Thanks.
How do I install the drivers for DM9601 ethernet adapter in Xubuntu? I firmly think that this is most likely a driver problem. I received a mini-disk during purchase of the usb-to-ethernet adapter with driver files to be installed in linux. However, I can't figure out 'How to do it!!!'. Is there anyone who can offer an easy step-by-step procedure for installation of DM9601 driver in Xubuntu? I have listed the output of important commands above. If someone needs any more info, I shall gladly provide it. It is really hopeless to work without internet in Xubuntu. Installation of some softwares are very difficult without net due to dependencies and stuff. Thanks.

Your device is covered by the module dm9601. Please load it:
sudo modprobe dm9601Is an interface, ideally eth1, created?
ifconfigWhen you click the Network Manager icon, does it show an available ethernet connection?
I suspect that your previous settings will all need to be deleted.
If you have an eth0, it appears that the internal ethernet is (sort of) working. I suggest we find out its driver and blacklist it so the two interfaces don't potentially conflict. Please edit your question to add the full result of:
lsmodDepending upon your response, I will further edit this answer to propose a solution.
2I have been facing this same issue on Ubuntu 15.10. So far I have managed to understand it is a driver related issue, at least for my ethernet adapter.

sig_hashalgo: sha512The problem is that the chip in the adapter is supposed to work with the dm9601 driver, but the actual manufacturer is CoreChip. So the correct driver would be the sr9700.
Another strange thing is that the interface the driver creates is called enx00e04c534458 (the number is also the MAC address of the adapter), which is different than any ethX for native ethernet ports.
The next thing is to force Ubuntu to use the specific driver and test the solution. I will edit the answer when I get more information.
I know this is not the solution, but hope this information helps in solving the issue.
