View Full Version : Wireless interference? Or problem with SB?

Stuart,

I occasionally see the "lost connection with SS" message, but (for me at
least) whenever the SS is rebooted or I modify network settings on the
SS, the SB player definitely reboots. The most recent "reboot" with the
SB player was difficult to notice, since it happened at the very start
of a track. I only noticed it because the display changed enough to
catch my eye. It's certainly possible that this was caused by "genuine"
interference, and if I'd been watching the display I may have seen a
"lost connection" message rather than a full reboot. Netstumbler
recorded a perceptible dip in the wireless strength around the same
time... But the main point is that on my player a complete loss of
signal causes a reboot.

Just as a matter of interest, are you using DHCP-assigned or static IP?

Dan.

Dan, Stephen

I also have exactly the same reboot problems. I've had them since I
bought
by SBG several months ago. Interestingly, I also have a USR AP (model
2249).

My problems were worse when I had the AP set in "Both" WEP
authentication
mode (especially when booting up). Changing to Shared mode stopped by
boot
up problems, but I still have the frequent / random reboots when playing

music (4-5 times an hour). This is not a signal problem. In fact, it
shouldn't matter if the signal was lost - the SBG should just report
"lost
connection to the SS".

I also suspect a low level firmware / hardware / code issue that's
causing
an issue.

Dan

Sorry - perhaps I wasn't clear. I also see the same hard reboots (screen
blanks, the logo comes up, then it goes through its reconnect phases). This
occurs several times an hour.
