Problems with the NetX can often be resolved by doing a factory reset on it. Press and hold the only button on the NetX unit for at least 10secs and then release it. Now check the iPronto network configuration as this will be the base that the NetX uses during setup. If the iPronto is set for DHCP then the NetX should also be set to DHCP and get allocated another IP address when it is configured. If the iPronto is set for a static IP address then what the NetX gets set to is not so clear cut. It may take the next IP address in sequence, which might already be allocated on your network and hence not work, or take the same IP address as the iPronto and then you must change the iPronto address to not conflict with the NetX. Generally using DHCP works OK but be aware that the NetX configuration screen in the iPronto can take a long time to get refreshed and display its name and settings. Remember that other Wi-Fi devices or networks may interfere during this peer-to-peer setup mode so take care to keep the iPronto and NetX fairly close together.
