This is not a complaint, as I know Powerline adaptors are not supposed to work outside the house etc. However, we had one working well with the AV600 in a garden shed, until an electrician re-wired the connection to outside (all he did was shorten the SWA cable going from the meter box to the shed). Now the AV600 shows a steady powerline light, but there's no internet connection. Bring it into the house, it works fine - steady powerline light, good internet; move it back to the shed - still a steady connection, but no internet.
Anyone have any ideas why it's showing those symptoms? Is there anything the electrician could have done? I've run out of ideas!
