i used the devolo 80mbps kit for my home network for months but all of a sudden they stoped working. i tried switching the cables to see if it was the cables but it wasn't them, i have 4 adapters so i switched two around to see if it was the two i was currently using but it still didn't work. the only thing i can say is that from looking on the devolo website the problem is with my dlan network? anyone know why this could be happening and what i need to do to fix it?
