"wireless carrier lost" -> complete network shutdown

[Marcelo Cavalcante]

I saw a fea people with a similar problem, but I'm not sure if it's really
the same situation, so let me ask you:

1- You have the same problem everywhere? I mean, on different places with
different APs?
2- What are you using to manage your network connections? netcfg,
networkmanager, wicd, ...?
3- If the answer for the first question is that you're having this trouble
with only one connection (AP), is this one using WEP, WPA, WPA2.. ?

best,
