I have 2 X-gateway AB7640-F where the IP address has been configured some years ago. The customer needs to change the IP address to match the new network, but it seems not possible. Note that I know the procedure to do this task, I did it to other customer when needed.
I tried as follow:
using your software tool IP config (latest version) : can’t find the devices, even conneted directy to it (on both devices same problem)
using the web interface of the device: I can enter the new IP, but after restart the IP returns like before .
I can configure the device uploading the configuration via USB, but this doesn’t help with the IP address (not possible to change it via configuration manager).
the dip-switches on the devices are configured for ‘IP from IPconfig’ and that’s ok.
Apart of this problem, the devices seem to work correctly (not defective)
Attached some images from the web page and the config software.
I am thinking about a firmare problem.
Any advice is welcome.
