Recently purchased a three-unit set of the M9 plus.
All is working well apart from pne issue. In router mode, the 'main deco' unit will not connect to the internet. The only fix I have found is to set up similar to 'AP' mode and place a router between the modem and the main deco unit. Then the system will work with no problems. I have swapped the unit to check for any unit issues, no change to the problem.
I realise I may not have explained myself very clearly, however all help will be appreaciated.
