Hi
If you have an issue connecting your internal Wifi to your home routers 5Ghz network then here is the solution.
Upload the attached file to folder /etc/brcm/ and overwrite the current config file.
Restart Enigma2 and you can now use the 5Ghz connection.
I assume this will be in the next update from Dreambox but if you dont want to wait this is how its done ;)
This also apply to the Dreambox Two UltraHD
