I had installed a 3.13v of RouterOS with level 6, i don't install any new version, because have problems with queues, i don't know for what reason. But... i need to know what happened to the option Hotspot universal client? I can't find that...

Sorry bad english.

universal client?.. what did you mean? I thought it's always here =)

To activate universal client in hotspot you have to specify an "address pool" for the hotspot server.
