Lossless ALAC over wifi?

I’m just dipping my toes into volumio v2 on a Pi 2 with an Edimax EW-7811Un N150 wireless USB Adaptor

I have a lossless alac music collection and am able to listen to it really well over a 600mbps powerline adaptor. As soon as I start on wifi i’m struggling, huge lag from any control app and intermittent audio.

According to the volumio gui the adaptor is connected at about 78mbps so I wouldn’t expect issues pulling a 40mb alac file over wifi from my nas to be an issue, especially with the buffers in volumio set to their max?

I’ve scouted around looking for solutions but i’m starting to come to the conclusion it’s a powerline adaptor :frowning:

So I may have posted too soon without running tests of use. The problem is definitely the edimax.

I’ve run a speed test on the command line via the edimax and got:

Testing download speed…^[…
Download: 0.38 Mbits/s
Testing upload speed…
Upload: 0.17 Mbits/s

I then tried the same from the same location on a different device and got the following:

Hosted by xxxxxxxxxxxxxxxxxxx [32.87 km]: 25.31 ms
Testing download speed…
Download: 32.83 Mbit/s
Testing upload speed…

… so its deffinetly pi / edimax related. I know the adaptor only supports 150mbps but i’d expect ore than 0.38mbit/s
