I'm not sure though how can any problem with the dhcp client prevent me to detect any wireless network.
It's working with the static IP so far, but I also have to say that it's also been two or three days between each "failure"...as well as 10 mins sometimes
Since I'm at it, I'd also thank you both for your effort...It's not like I have to have a database running or any other "mission critical" task, but those failures are nonetheless quite annoying...and therefore any help really appreciated.
Anyway, I don't know if it could be a relevant info, but my router sets a dynamic IP address to "decay" after 24h...that is, 86400 seconds.

Add "renew 2 2010/12/2 23:00:00" without "" somewhere into /etc/dhcp3/dhclient.conf.
This should tells dhcp client to change IP address on 2010/12/2 23:00:00 (I hope), and in /var/log/daemon.log shouldn't be many "localhost dhclient: DHCPREQUEST"
Not that I know much, but ... this sounds like a wpa_supplicant scanning issue, that I encountered in Karmic Koala alpha Kubuntu 9.10 ... I wasn't using any encryption and this confused the wpa_supplicant scanning; whether or not I created a wpa_supplicant.conf file and wexp driver (for my Broadcom 4306 builtin on may acer ferrari 3400. Even setting ap_scan=0 did nothing and I regularly got a 2MB daemon.log.
By the way, what is the make and model of your wifi card, and what driver are you using?

Raid 6? I don't have any raid array on my laptop...and with a single disk it'd be hard to get a raid 6!
minrich: lspci lists my wifi card as "0b:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)". As I said, I'm using a Dell XPS 1530.
How do I find out about drivers? I didn't install anything, with every version of ubuntu all peripherals start working at once without intervention...
In most EMEA market, as well as in the US, Canada and most south american countries, XPS 1330 laptops were sold with ubuntu preinstalled, so I'd think all the hardware should work out of the box.
I know I'm talking about a 1530, not 1330, but the only notable exception is the gfx card, which posed no problem for me.
A friend of mine has a 1330 though, and he has this same problem with the wifi connection.
Anyway, as I said a few posts before, I am filtering mac addresses on my router, so I could even do without the password (encrypted wpa-psk), but will that confuse wicd even more?
Johnnie.it : Your firmware is loading (automagically) at 22.xx seconds in your listing above. Do you have a file @ /etc/wpa_supplicant/wpa_supplicant.conf ? if so, can you post its contents. Also if you do have you checked your /var/log/ directory for a wpa_supplicant log - I am not sure if this is only created if you run # wpa_supplicant with a --dd option in a terminal, as far as I recall it basically duplicated what was shown in my daemon.log.
Don't know if your wifi is up or down at this moment but could you post output of:
ifconfig -a
iwconfig wlan0
iwlist wlan0 scan
nimnull: being a wireless network, it's a bit difficult to identify a *physical* link.
I only know that when it happens, the icon in my systray goes "Disconnected", the network manager (gnome net man before, wicd now) can't find ANY wifi hotspot, and I can't connect to the internet (of course) nor even to my own router, on my private network.
Actually, thinking about it, I'd say that there are no more reconnection attempt because it cannot find any network to reconnect to....
minrich: nope, no /etc/wpa_supplicant/wpa_supplicant.conf
I checked my wpa_supplicant logs (also .1.gz, .2.gz etc.) and they're all blank. Weird, isn't it?
Further to nimnull22's advice above - please make a check (when the router/ap disappears as predicted) of your ifstate, if I remember correctly yours will be in /var/run/ in debian lenny mine is at /etc/network/run/ , also check the contents of your /etc/resolv.conf and make sure you have: nameserver 192.168.1.1 {or whatever you have set your router IP to}.
Just for info, I have installed wifi-radar on my laptop since I can set all but the ap address to reconnect almost automagically when I am dropped by my wifi ISP, without having to use a string of commands such as ifdown wlan0, ifup wlan0, iwconfig wlan0 essid myapname commit, iwconfig wlan0 ap 00:00:00:00:00:00, and iwconfig wlan0 channel 4. These were all required to restore my wifi connection, notwithstanding the fact that I have all these details in my /etc/network/intefaces:
allow-hotplug wlan0
iface wlan0 inet static
address 10.0.0.7
netmask 255.255.255.0
broadcast 10.0.0.255
gateway 10.0.0.1
wireless-essid myapname
dns-nameservers 10.0.0.1
Anyway, I don't think it's a wpa_supplicant problem.
As I said, when this happens, my network manager can't find *any* wireless network, regardless of encryption, essid or anything else.
My ISP also provides a free connection; that is, it's unprotected when you connect, but when you open a web page it automatically loads a page asking for your login and password so that you can browse.
The point is, when the network manager gets stuck, it can't even detect that one...
It's just like my wifi card shuts down every now and then...
Lets make things simple, can you turn off wireless encryption/protection (Wireless Security), so you can connect to it without password for 2 days for the test.
