Intermittant Network on boot up

Hello All, I'm running SlamD64 12.1 on an HP 64 bit laptop. I have a nvidia (sp?) network card. Am using a Broadcomm Driver written for linux (well maybe adapted for linux) by Broadcomm or Nvidia I can't remember.

Couple of quick questions.

1) Is it common for occasionally the WiFi card not to be reconized. Example, I occasionally boot up and the steps will stall for a few mins after renaming eth0 to wlan0. It then continues but when I get fully running I can see all the networks around me but can't get an IP. I usually have to boot to Windows Vista, get on line, log off and reboot to Linux. Sometime I have to boot 3-4 times, but once it's running, I can boot 5-10 times before it happens again. I haven't been able to link it to a common event that maybe causing it, just thought someone else might have been running into it as well.

2) How can I skip Wifi config when I'm booting up outside of a network. Currently I get to a point in boot up and it stops forever it seems looking, before giving up. Is there a way to tell it, if you don't see a network in a few sec, just skip and go on?

These aren't major issues but get to be a major annoyance.

Sorry for the lack of screen output/errors but I'm not near my laptop at the moment.

Thanks in advance for you attention.

You may investigate the possibility to use wicd (wireless interface connection daemon), which is wonderful if it functions with your dist/version/wificard. Conflicts with wlanmanager though so may be tedious to test if you cannot verify functionality on beforehand.

On the other hand, there may be a possibility to use ifconfig/ifup/ifdown after boot with network not always fully configured (happens to me just now sometimes, don't know why, after upgrade to ubuntu jaunty). The procedure I use is:

sudo ifconfig [tells that my interface IS configured but lacks IPno]

sudo ifdown ath0 [brings my Atheros card down in order to make next possible]

sudo ifup ath0 [brings it up and aquires an IPno from my router; did not succeed at boot, why?]

Hopefully, the WLAN should function now, and you may see an IPno with another ifconfig if all is in order.

Now my card is Atheros (ath0), use your actual device instead. Note: The ifup procedure may perform additional exercises regarding mounts and some other daemons as well but don't worry.

For me this is a temporal solution until I get my wicd running again (I am in a quadruple transition as regards major upgrades of Wicd, Ubuntu, KDE, and the Atheros driver for the Linux kernel, so it may take some time).

Hope you will come to a solution!

P.S. I don't dare trying answer your questions -- very similar to my own ...
