View Full Version : FW: wireless connection very intermittent

Owen,

Thanks so much for your reply!

I have fiddled with the firewall settings quite a bit and they seem to have
little effect. For example, I have disabled mac address filtering and
enabled it, specifying the squeezebox mac address. In both cases, I get the
same results.

I have set virtual server settings for the ip addresses corresponding to
both the computer with the slimserver software and the squeezebox itself,
permitting all of the relevant ports.

DHCP is set up properly and seems to work. Even though symptomatically, it
appears to be a weak signal, I think something else is going on here. Has
anyone else run into this kind of problem?

Thanks again,
-P

Peter, are you running 5.0.1, or one of the nightly builds?

Also, can you try testing with ethernet instead of wireless?

The reason I ask is that this seems to be a new issue, and I'm
wondering if there might be something going on in the most recent
firmware/server that is causing it to drop the connection even though
the network is okay.

I am looking into this with another customer right now so I hope to
have an answer soon.

I am experiencing this, as well. I generally receive a weak (30% or
so) wireless signal just a few unobstructed feet from the base station.
Playback is spotty, often stopping after a few seconds. When I am
plugged in via ethernet, all is well, so this seems definitely to be a
wireless problem. There doesn't seem to be a problem finding and
connecting with the network -- it's just that the playback doesn't work
well, if at all.

I am running 5.0.3 from about a week ago, but I noticed this problem
when I first installed the 5.0.1 release.

Equipment:
Squeezebox (firmware: 5)
OS X 10.3.2
Airport base station

Any help is appreciated -- and I'd be happy to upgrade to the latest
nightly builds to help diagnose the problem.

-d.
