I read that wall mounting helps with the heat issues, improving stability.
Its weird because on that speedtest you linked you have 7ms, which makes it look you still have interleave off (fastpath), which would be the first thing to turn back on if you have stability problems.
For the first 10 days BT leave interleave off, after the 10 days they turn it back on permanently. This is a shame because I'd prefer interleaved off for the better pings
