Hi, I changed providers yesterday and plugged in the supplied router (Vodafone SHG2000) No changes to my home network. Got the modem up and running all devices connected to internet on WiFi. When I plug in the power line adapters with the av600 wireless out in the outside workshop I don't get any internet out there either WiFi or plugged in. After 10 minutes all devices are no longer able to access internet, still got WiFi signal but cannot connect to internet. When I unplug power line adapters all goes back to normal after a few minutes. If I plug in only the power line adapter to the modem and not the outside av600 I still lose internet on the WiFi connection to all devices. Again when I unplug the adapter all returns to normal after a few minutes. Anyone experience this, all help welcome. Vodafone only offer a replacement modem.
