View Full Version : sound quality issue

2.4ghz wireless is a bear to troubleshoot. I have used spectrum analyzers
to do it in the past. First things to do would be to try different radio
channels on your wireless access point and see if that has an effect on the
problem. Another thing you could do is try to temporarily test by placing
the squeezebox closer to the access point and see if the dropouts decrease.
Also don't forget the affect of 2.4ghz cordless phones in use by you or your
neighbors, or microwave ovens.

A final desperation move might be the purchase of some 802.11a access point
and ethernet bridge, 802.11a operates at 5.4ghz frequency range and is much
less likely to be the subject of interference.

Is that because 802.11a is fundamentally more resistant to interference,
or just because 5.4ghz gear is rarer these days? Aren't there phones in
that band, as well?
