Description Mick 2006-02-01 11:13:18 UTC
Router Mfg            : Belkin
Model                 : F5D7230-4
Router FW             : 4.05.03
802.11                : B+G
SSID Broadcast        : Yes
DHCP/Static IP        : Static
Wirless Channel       : 11
Protected Mode        : On 
Turbo/Frame Bursting  : On
MAC Filtering         : Off
WEP Security          : Off
WPA Security (128/64) : Off
Use as AP             : Off
Wireless Bridging     : On

Other Info : I also have a Belkin AP on my Wirless LAN to boost the signal at the back of my house. It uses the same channel & SSID for seamless roaming.

Symptom : Audio dropouts/buffer underrun after about 30 seconds of playback of MP3 files.

Also experiencing dropouts with v29 of firmware.  SB3 loses connection to server at what appears to be end of song.  MAY be related to the "Requesting web page to keep SlimServer unswapped, re-request interval is 30 minutes."

I am playing Apple Lossless files from an Intel iMac with SlimServer version 6.5b1.

BTW as an additional data point.
I tried disabling Frame bursting on my router with FW29, but it still made no difference to the buffer underruns. The network strength however did seem to improve. Although time of day could make a difference here. Less microwave radiation etc...

My Belkin router help says that Frame Bursting enables some 802.11e features. doing a google search for 802.11e & Atheros reveals that their chipsets have supported Frame bursting and QoS since about mid-2004.

I wonder do the drivers for embedded devices implement QoS or Frame Bursting.

From the Belkin Router help

Turbo Mode
Selecting "Frame Bursting" will result in all devices capable of Frame Bursting to function in frame bursting mode, and all clients not capable to operate in normal 802.11g modes. Frame Bursting mode supports both Frame Bursting enabled devices and non Frame Bursting enabled devices simultaneously. Frame Bursting mode is based on the unreleased 802.11e specification.

Selecting "Off" will disable all turbo modes

Have you tried changing your wireless channel? Also, can you check the CPU load on your computer?

Router Mfg            : Netgear
Model                 : DG834G V2
Router FW             : 3.01.25
802.11                : G only
SSID Broadcast        : Yes
DHCP/Static IP        : DHCP
Wirless Channel       : 11
MAC Filtering         : Off
WEP Security          : Off
WPA Security (128/64) : On (128)
Wireless Bridging     : Off

Using latest 6.5 nightly with ActiveState Perl on Windows XP. Two Squeezebox 2's and server all connected via wireless to the router

Both my Squeezeboxes will connect to the server intermittently (ie they will be connected for an hour or so, then they will lose the connection for an hour or so).

When the Squeezeboxes have lost the connection, if I restart a squeezebox and go through the network setup, the squeezebox will connect to the router successfully and receive an IP address via DHCP, but the server will not be found.

When the Squeezeboxes are connected, remote response is incredibly slow. When playing MP3s the buffer never fills completely, and when playing FLAC I get constant stuttering with the buffer at 0%.

Everything worked fine with FW28 - I only get the problems with FW29.

Hi, since installing firmware 29 I have had stuttering in the music after 4 or 5 tracks, restarting the track will cure it for a while.  AlienBBC has problems immediately with streaming, not the garbled problems I used to get.  I'm running with a Netgear DG834GT, latest firmware, 128bit WEP.

Upgraded to FW33 tonight and my SB2 is now back behaving itself with my Belkin F5D7230-4 router.

Based on the feedback of others, this looks resolved.
