GUI Connection Troubleshooting
1. What if I don’t know the serial interface to the modem?
The modem has a default baud rate of 115200, if you are not able to connect via
the serial interface at any baud rate, then restore the modem to factory defaults
by holding down the reset button for more than 20 seconds (5 second hold is for
profile reset).
2. Why does the Intelimax+ GUI not connect and reports “The attempt to connect was
forcefully rejected”?
If the Intelimax+ GUI connection to the modem is not closed with a TCP
disconnect the modem may reject connections and report with a message “The
attempt to connect was forcefully rejected”. This occurs until the modem TCP
timeout occurs which will be either via a modem reboot or after at least 10
minutes. If the connection is local you can shorten this time by reconnecting the
USB interface or under network connections, selecting the LAN interface to the
modem, disabling, then enabling this interface.
3. Why does the Intelimax+ GUI show that the device is discovered but not connect?
The LAN interface to the modem needs to be configured correctly. This may
involve setting a static IP address to the modem, such as 192.168.10.50 or
removing an incorrect address. The GUI will continue to try to connect to the
modem 3 times after the ‘Open’ button is pressed.
4. Why is the GUI not detecting the Intelimax+?
The Intelimax+ must be powered via the RJ45 connector, then the USB plugged
in, after approximately 1 minute, the PC will prompt for drivers to be installed. The
Intelimax+ requires the USB/LAN interface drivers installed to be able to talk via a
TCP IP connection to the modem, which can be downloaded from the Maxon
website.
There are times where the RNDIS network interface is present under network
connections but not when checked via a command line (ipconfig). If this is the
case then the PC must be restarted as the Microsoft Windows RNDIS driver is not
functioning correctly.
