Yep, that's what fixed it at my parent's house. I disabled every power saving mode on my computer, on the router and on the adapters. You can also get some benefits from the router and the adapter being on the same switch group.Ive just ben looking into it and there is a power saving mode on them that must be turned off. Then they can still go to sleep, but apparently setting up a constant ping to your router can stop it from happening (I have just done that)
If I can sort the disconnect I should be good as im getting 10ms ping, 60 dl and 20 ul through it.
Looks like I might have contacted Marius during this disconnected state last night
I still recommend a direct ethernet cable as you lose so much speed (and packet loss) over distance with these power net adapters.
