View Full Version : My NOT good wireless experience

ralph, just a thought, and i'm vague on the details, but i've seen
situations where two "802.11" products will not talk reliably to each
other

hence the non-profit www.wi-fi.org, which created the "Wi-fi"
certification mark for the subset of 802.11 products that have been
tested as interoperable.

if both ends of the network (perhaps all devices on it?) are not "wi-fi"
certified, you may have incompatible devices

hopefully others with better knowledge can cut in at this point...

Thanks. Still rebooting at random.

My DHCP lease time is the standard Linksys 1 day. Shouldn't be a
factor, one would think.

It just happened again -- rebooted. Even though IP is fixed and network
is hardwired to B only.

-d_protocol log shows:

2005-02-24 13:30:00.8762 Got discovery request, deviceid = 2, revision
= 2.8, MAC = 00:04:20:05:87:b3
2005-02-24 13:30:00.8763 It's a squeezebox
2005-02-24 13:30:00.8763 calculated rehome length: 17
2005-02-24 13:30:00.8765 sent discovery response

Any other debugging I could set that will help?

I will try different channels and see if that helps.

Any help is still appreciated.

As a datapoint, you may try turning off WEP. I'm not suggesting this as
a good long-term solution, but you might consider something like MAC
filtering if WEP is indeed the problem with your particular setup.

I don't have my squeezebox yet and I'm getting the wired version
(though slimserver is on a wireless box) - I would like to note that
it is rather trivial to sniff both MAC address and SSID key even if
SSID is not broadcast and MAC filtering is on. That may not be a
concern - I don't have WEP on myself, I'm not worried about people
using my connection for illegal stuff etc. but there are tools
specifically designed to take advantage of non encryption protected
networks, if you live where there are a lot of people going buy, etc.
or in an apartment, you may not want to disable WEP, last thing you
want is your IP associated with a child porn sting.

Turning WEP off might help diagnose the problem though, maybe you
should try 64 instead of 128?

It's not cake to crack - it takes collecting data for as long as a
month or so in order to have enough to do it. Sure, it can be done,
but it's a whole lot easier to just find one of the many unprotected
networks.

Given typical SB data rates and usage patterns, I don't believe it would
take very long to have enough data to compromise a WEP key in this
application. The cracking tools are fairly idiot-proof. That said, WEP
+ MAC-filtering is the best you can currently do, and it's probably
worth doing.

One possible alternative would be to make the SB wireless network
unroutable (ie. no gateway for Internet access). That would make the
network a very unattractive target. In this case, you might want a
second NIC in your slimserver if that box also needs external access.
