Squeezebox Touch: jitter thru wi-fi?

Kijanki, yes, buffering helps reduce dropouts however I believe if throughput between server and Squeezebox client goes too low, the buffer still might not be filled fast enough to keep music flowing. That is what I experience on occasion with similar Roku Soundbridge product, and would expect similar with any network player device.

Mapman, I have dropouts sometimes (once a week) - much better now since I found microwave oven frequency in its manual and changed wireless channel away from it. Ideal would be to switch to 802.11n (5GHz) but my MacMini doesn't support it.

Yes, I have had occasional dropout issues with wireless G as well and found changing router frequency can help.

With the default frequency/channel configured in my router for wireless G, I found that my Rokus would loose their connection to the server temporarily whenever our wireless phones rang for an incoming call. The wireless phones were apparently interfering on that frequency. Changing router channel configuration solved that problem.

Hadn't considered microwaves. Next time I get a delay, I will have to check to see if the microwave upstairs is in use......

I don't think wireless dropouts will be a problem unless your signal strength is marginal. You probably already know whether this is the case if you use wireless in the house.

I certainly don't see any basis for a statement like, "For a hi resolution system, I would avoid wireless. For streaming background music and such, it is great."

Its true that higher resolution and lossless files have more data to transfer and may be more prone to delays due to throughput limitations on a wireless connection if present. For example, I seldom get a dropout playing mp3 files, but it can happen on occasion with CDs ripped to lossless .wav format.
