For this device, the ID is 1241:1166. Take your device ID and google that.

Hi there,

you probably need the package usb-modeswitch installed on your system. Check with the packet management tool of your distro, whichever it is, if this package is installed; if not, have it installed.

Most USB modems are actually hybrid devices: When plugged in, they first announce themselves as a generic USB storage devices which holds the drivers and additional software (but usually for Windows only). On a Windows host, autorun kicks in and installs the driver automatically, if necessary, and then flips a switch inside the device. This switch causes the device to disconnect and then reconnect, this time announcing itself as a communication device.

In Linux, the usb-modeswitch package flips this switch, but it isn't installed with every distro. For me, usb-modeswitch solved this problem in Ubuntu when I also wanted to use a Huawei UMTS Modem.

this sounds like we need information about your internet provider to help you solve your problem.
most dongles should connect out of the box these days, but it seems you have some weird contract that requires you to register through a browser first?

this is meant in addition to what the others asked/suggested.
also, what's your distro and desktop environment and network managing app?

It sounds like you browser on Windows has 192.168.1.1 set as it's home page.
If using that address directly works and you want that to be your default when you open a browser then setting it as a homepage in your browser's settings should be enough.
