I have recently bought a TL-WPA4220KIT pack and am having trouble setting it up
I have followed the instructions and plugged the adaptor in to a mains plug -not into a power strip - and connected the Ethernet cable into my Virgin Super Hub which is in router mode and plugged the adaptor into next door and connected my smart TV and blue-ray player
The power LED and Ethernet LED are on but the powerline LED is not showing its light
Is this a possible problem with the SuperHub( which I have no problems with otherwise ) ?
Any help would be appreciated as this is baffling me :confused:
