I did a factory reset on all 4. I think the new version is problematic.To be honest, I'm considering getting a refund for these and going back to the devolo 1200's

UK version here, but same, constant dropouts since the 2017-06-28 (UK) Firmware

Mine has just started doing this, the middle light flashes red. I updated 3 of my 4 adapters to the latest firmware (UK) last month, 1 won't update for some reason. Any ideas of things to try?

The Vogon wrote Upgrading via Ethernet is more reliable. There's no other way is there? I thought the Utility only works if you're connected via ethernet

I bought from Amazon UK so I presume it's the UK I see the link above is EU, I should be using the following I guess, I can't see 2016-10-25 on there though?...

Update failed :( Current version is 3.2.0_902131_160405_903
