I have two Powerline AV 200 devices that have worked, without issue for around 6 months. But for the last week the powerline led (the one that tells the link rate) on the one next to the router has been red or orange, while the one in my room has been green then orange for a while then back to green. Could this be due to the weather (live in an old house), or could it be that more electrical devices are plugged in?
Thinkbroadband speed test gives me 9.4Mbps (although it has given me 4.8 etc a few times) and speedtest.net shows 10.30 Mbps (and only move a few digits up and down)
