For wi-fi streamers--a discovery to increase wi-fi strength


It was previously reported in a thread here that putting a piece of aluminum foil  behind a router can increase wi-fi signal strength, and I verified this with the Bluesound app for my Bluesound Node streamer.

Today, because I was having some internet speed problems, I experimented with the orientation of the base router of my mesh network, and found this made a significant difference in the wi-fi signal strength, going from "Good" to "Excellent."

Then for the first time I added a piece of aluminum foil behind the extension router unit nearest my streamer, and that further improved the wi-fi signal strength from -48 dBm to -43 dBm, the best reading I've ever gotten with this mesh network.

Given that an "Excellent" reading is considered by Bluesound to be necessary for streaming hi-res files, this is an important consideration for those doing wi-fi streaming.  And perhaps some members who have been disappointed with wi-fi streaming didn't have adequate wi-fi signal strength.  I suspect the audible differences (at least with the Node streamer) lie in problems with dropouts and buffering rather than sound quality, but I'm not certain of that or whether that would be the case for all streamers.

I ran my BS Node for 3+ yrs on FAIR signal strength with zero problems with any hi res files, and no dropouts or buffering. I didn’t plan on wading into the Ethernet vs Wifi fray but there are actually some manufacturers that suggest a well designed wifi module is a better streaming interface than ethernet from a potential noise perspective - Auralic for instance. The argument is that 1) the noise in your router is likely high by audio standards so why connect to it and the ethernet cable is also subject to noise/jitter and 2) wifi can be cleaner if there is error correction and that error correction only needs to be used sparingly (otherwise it produces internal EMI - which I doubt can be heard). But as long as files arrive intact, I can’t understand how it makes any practical difference, at least in my modest $20k system.

@normb Sorry, no.  I had a 10' Radio Shack antenna on a motor to turn it and got excellent FM and TV

You can get a wifi relative quality reading with a mac computer about this mac,

system report wifi it will tell connection quality mine next to node -31 dbm signal

-98 dbm noise

@drmuso I started my streaming journey a few years ago with a Node and Ares II. Actually had a Cambridge DAC Magic briefly before sending it back after the trial period and getting the Ares. Based on what I remember you should: (1) Hear a nice improvement over the Node using the Ares; and (2) hear an improvement using a mesh extender over wi-fi but the difference is not as significant as the difference between DAC’s I don’t remember reading what your electronics or speakers are but if you’re not hearing a difference in SQ between DAC’s I’d be looking at improving those components.

Thanks for that tip.  I also have a MacBook Pro, but didn't know you could test the wi-fi that way.  My readings aren't quite as good as yours, though, so you've got great wi-fi.
