View Full Version : Wireless AP - Network problems

I have 2 hard-wired Squeezebox1 devices. One is wired directly into the hub and works flawlessly. The other is hard-wired to a wireless access point (WAP11b) that talks to another WAP11b access point (which in turn is wired directly into the hub). I'm getting occasional dropouts on the wireless access point connected device.

I've tried playing with the channels, preambles, transmission rates, etc. and have not had much luck. The problem is difficult to work on because it is intermittent.

Anyone have any tricks or advice? Is there a way to buffer the data the way a wireless Squeezebox would to help prevent some of these drops? Any settings you've had luck playing with? Is there atleast a way to test this signal strength? I can hard-wire a laptop into the remote access point if there is software that will test the connection without requiring a wireless card.

Many thanks...

I had a similar problem... I was transmitting via a bridged wireless
connection to an SB1. The connection from the SB1 to the hub was wired.
When I switched the bridge to 802.11G (instead of the lower bandwidth
"B") , it solved the issue.

I should also note that I (mostly) use MP3s at 192k, so I was surprised
that it seemed to be bandwidth issue. However, the wireless network here
is used by a few PCs, a TiVo, etc., and when I was on "B" and removed
the WAP encryption, it helped a bit. The "G" speed finally did the
trick.

Dunno if that will lead you to a solution - just my 2 cents ;-)

I've ruled out any encryption problems, and this is the ONLY device talking to the other wireless access point. I also stream MP3s exclusively so bandwidth problems would surprise me.

Anybody have any tweaking suggestions for a 802.11b wireless network?

AFAIK, both the wired and wireless SB1s have the same hardware data
buffer.

Two strategies:
1) Increase the link bandwidth
-deal with channels, interference etc.
-use antenna reflector (see link)
-use high gain antennas
-upgrade both ends to 802.11g
2) Reduce link traffic
-transcode to lower bitrate for the affected SB1

antenna reflector template:

many others available.

Thanks. I built a little reflector antenna and it does seem to have made a difference. Transmission rates don't seem to have really improved, but they're very consistent. I'm not seeing any of the random drop-outs in speed.

Cool. Glad that helped. Did you build one just for the SB, or did you
do both ends? Might see even more gain with two.
