I know it's an old piece of kit, but my TL-PA211 adapter was working perfectly until this morning, when it suddenly showed no lights at all or other signs of life. I've tried it in other sockets, but to no avail.

I guess it's probably died of old age and needs replacing, but just thought I'd ask before junking it in case it might be possible to bring it back to life with a software update or some other trickery?

Thanks
