Pretty sure flashing red blue means your not connected to a reflecter, when im connected to a reflector and it goes off line for whatever reason it flashes blue red untill the reflecter comes back on-line or i go to another reflecter, so your connected to WiFi but not to a reflecter, what reflecter or whatever are you trying to connect to. if you see special connecter or null connecter on the web page your not connected to anything except your WiFi, you will need to connect to something like America link on fusion or REF030C on D-Star or a DMR room like TG91, i have plenty of PC savy friends that are a fish outta water when it comes to anything radio
