Laptop’s internet via tethering gets dropped when connects to Ericsson MiniLink

[zillah]

Dear Experts

My Windows 7 laptop connected to internet via my mobile Samsung Galaxy S3 by tethering portable Wi-Fi hotspot.

I am a technician field and I need to connect my laptop via USB port to an Ericsson MiniLink (telecom NE) node to do configuration.

Whenever I connect  the USB cable from the laptop to Ericsson my internet gets dropped, while this didn’t happen to my coworker who is using the same laptop brand as mine.
 
By the way the Ericsson software  that I installed on my laptop create the attached socket called : "Ericsson USBLAN adapter" on my computer's network and that would be used for the USB communication

Make sure that the Gateway IP is not set up for this other Network Connection, and that the Gateway configuration is only set up for the Network Adapter with the Internet connection.

Go to command shell and type IPCONFIG/ALL and copy paste that info here if your confused about this and we can look over your Gateway info to suggest the specific adapter etc.
