Netgear has recalled its XE103 85Mbps powerline Ethernet adaptors sold in Europe. The adaptors are designed to establish a home network over electricity cables and thus avoid running of additional Ethernet cables.
The problem seems to be associated with the risk that the device could overheat under some circumstances, causing a fire. RegHardware reports that Netgear have not actually had any reports of this happening but are recalling the units as a precaution. The recall only affects 220-240V versions of the adaptors.
You can check if yours is on the recall list by visiting the Netgear website.
