Hotspot Questions

I am using a Hotspot which uses the raspberry pi with Commander.  I have two of these Hotspots, one with DVmega and the other with with a dual band module.  I use these connected to my home network and other WiFI connections here in the United States with very little problems.  Once in a while I do loose the ability to use CCS7 but most of the time its working.  I am not sure who to report issues of it not working since when this occurs since Commander and the Maryland user image seem to have the same issue from time to time?  Another issue, and one I hope I can get help with is; last summer I took the Hotspots to Europe; England, France, and the Netherlands and when I hooked the hotspots up to several different networks there, I was unable to connect to anything i.e. reflectors or stations using CCS7.  I assume its a setting issue as many amateurs are using these same modules in Europe.  So reaching out here, what am I missing and where would I find instructions to set these up so I can use my Hotspots when I travel outside of the United States?  Thank You in advance for any suggestions you folks may have.
