For 3 or 4 years I had my Vesper XB8000 and Axiom MFD playing nicely together.  The setup had a boat Wifi network and the STNG bridge.  AIS targets, NMEA 183 data and MFD data appeared on Aquamaps and WatchMate on an iPAD and AIS targets appeared on the MFD. 

In the last couple of years I’ve had to replace my VHS/AIS antenna, upgraded the MFD and swapped and reconfigured the Wifi hardware.  I must have missed some settings as I have not been been able to restore the AIS data display to the Axiom+.  The tablet seems to show all the data from AIS and 183, so the messages are on part of the network.   

Can someone suggest how to troubleshoot this?  I suspect the Axiom configuration is wrong, but I may just be blaming the last configuration to arrive.
