View Full Version : Wireless bridge / Firmware crash

I've been trying to track this down for a while - but still haven't a 100% reproduceable case.

I use my SB2 as a wireless bridge - connecting the SlimServer PC via 100M ethernet. This work fine - and will play music forever without problems.

However if I do something very intensive dragging data off the SlimServer PC which uses SB2 as it's wireless bridge - I get an interesting firmware crash.

First I stop getting network access vis the bridge, and at the same time the SB2 display freezes. Music keeps playing though - although with some 'crackles' (I use the digital out). Once the track is finished the SB2 then completely freezes.

A power off will reset it - and as long as I don't talk to the PC via the bridge I don't see any problems.

In normal non-intensive use I see occasional similar crashes - but they happen much more often if I'm backing up files or viewing photos that put a lot of traffic through the bridge.

Anyone seen anything similar?

I'm using a linksys WAG54Gv2 with recent firmware, and a mix of B & G on the WLAN. In the crash the laptop is running B and the SB2 G - although I still see the problem when I run everything in B. I'm running 6.2.1 & firmware 28.

Well, there's an existing bug where DHCP requests an IP address with the wrong MAC when the SB2 is in bridging mode. It's possible there could be other bugs related to that, although I've never seen any of what you describe. You might want to set it to a static address, if you haven't already.

If it has a static ip and still does that... you might have a hardware problem. I have two Squeezeboxen here, and they have been absolutely flawless for me in bridging so far. Admittedly, I haven't done any really super-bandwidth-intensive stuff with them, but I've _never_ seen them crash or act even a tiny bit funny.

Since you haven't gotten any other replies, I'd tend to think it's a hardware problem. (which is a bummer, but at least it should be fixable... not something you're stuck with.)

I did some speed tests (http://forums.slimdevices.com/showpost.php?p=75876&postcount=4) in bridged mode. The tests saturated the connection (about 14 Mbps in my case), but only for about 30 seconds or so.

Worked flawlessly for me.

How long does it take to cause a crash in your case?

This possibly sounds like it's getting excessive packets queued up somewhere and running out of memory, but that's just a guess. Can you get it to hang by using the bridge mode when it's NOT playing music?

Sean, sorry about the slow reply - but I've just got the time to experiment with this. I can't get it to crash without the music playing (all the music is Apple Lossless) and a long playlist.

So I suspect your analysis is right. It's not all that easy to reproduce on demand - so I suspect it's a combination of a lot of wireless bridging, at the same time as a playlist refresh etc.
