@Madascanbe What does your network setup look like?

@INFO404AK I tried the same a few months ago with my C80 and 2x Deco M9 plus units with a switch. I also got a network loop so gave up and changed my setup removing the C80. It could be your switch...

@D_E_R_E_K On Deco app go to "more" > internet connection > IPV4 connection > internet connection type & choose "Dynamic IP". In order to do this you will need to be connected to the wifi network.

@klipse Failing that you could leave your old router in place and set the main Deco to access point mode, in Deco app go to - more> advanced> operation mode> access point, apply and deco will reboot.

@ashikur32 On Deco app go to wifi settings > advanced and make sure both bands are enabled.

@Colinski585 Hi It could be because the main deco is not able to get the IP address configuration from your ISP for various reasons, there's not much online for Pavlov fibre except a post on Reddit...
