My PC is attached to the netMod through a USB connection. While I am connected to the Internet I am facing a lot of problems. My connection is either interrupted or not responding, while my computer crashes often and unexpectedly with blue screen (or restarted).
Check if there is any conflict between netMod with any other devices of your system. In case your PC is equipped with an internal card-modem, we recommend installing the netMod to the communication port COM3. Remove both modems and reconnect the USB cable without restarting your computer. Check that you have installed the specific USB drivers for your main board USB system and not standard or generic drivers. Contact the computer's manufacturer to help you about this subject.
Update your firmware and the USB drivers for netMod according to the installation guides of our webpage.
Alternatively, if your computer is equipped with serial (RS232) ports then you can use a serial port connection to the netMod. The ports COM1 & COM2 use specific IRQs (interrupt request) from the BIOS without sharing these IRQ with any other device.Start of page
I plug the netMod but my computer does not recognize it or recognizes it as an "unknown device".
Check that your line and the power led is working properly. Try to reset the netMod (black button inside) or plug the USB cable to another USB port of your computer. Afterwards, restart your computer and open the Device Manager. If you find the netMod device ticked with an exclamation mark, then remove (uninstall) this device. Then run the installation driver setup program and plug the USB cable. Do not use long connection cables. The limit for a USB modem cable is 5 meters and for the serial port is 10 meters. In case your computer is located far away from the netMod, you can extend the U line cable.Start of page
