I live in Essen/Germany
Today I have checked via Windows Explorer my Network and recognized beside the FRITZ!Box a ”HomePlug AV Wireless AP”.
I do not use such system nor have I installed a homeplug devise.
Can someone out of my apartment house or neighboring houses enter my laptop or computer via this way?
I have searched in Google.com regarding this matter and saw this is a problem on other PC’s also, but could not find an answer.
