6s wifi issues with Devolo dLan 500
,
I live in an old house with thick walls so have to extend my AirPort Extreme
network with some powerline wifi repeaters from devolo (dLan 500 WIFI).
I find that when my iPhone 6s is connected to one of the devolo devices I am getting shockingly slow downstream wifi speeds compared to my wife's 5c and an old 5s. See the attached photo for a test using the Speedtest app, at the same time from the same location, all using the latest iOS. I can repeat these results every time, as you can see the 5c and 5s are getting 25-30mbps downstream yet my 6s only manages 1, rarely getting even as high as 2mbps. All have similar upstreams.
I can't pin down exactly when it started, but it never used to be this noticeably slow.
I had a broken screen replaced at Apple a couple of months ago and it's definitely been an issue since although I can't say it wasn't slow before.
I don't see any wifi performance problems when i am close enough to my AirPort Extreme for it to use that and don't seem to experience any issues with public wifi or at friends/work etc.
I'm at a loss for what's happening here but it's basically rendering my iPhone almost unusable on wifi when at home which is obviously quite frustrating.
Does the iPhone use different antennas for upstream and downstream? Could my screen replacement have introduced this issue?
I've tried obviously restarting and resetting to defaults the devolo devices and forgetting the network and resetting network settings on my iPhone but still get the same results.
Cheers
