[gentoo-user] wireless on boot

Hallo!
How can I set on boot time my lan connection using a usb card?
Some service need internet on boot (ntp-client, etc.) but I cannot find 
a script on /etc/init.d/ to support it.
The connection uses wpa.
A second question: some times the connection gets down but dhcpcd 
doesn't see it and the only solution is to kill wpa_supplicant and 
dhcpcd and restart them.
How can I prevent this problem, or connect automatic again?
Thanks,
Luigi

If I understand you correctly, you won't find the entry you're looking for.  
You need to create a link with the name of your usb card interface. 
ifconfig -a will show you what the new network card is recognised as and then 
you have to link it to /etc/init.d/net.lo.  For example, if ifconfig shows 
you a new interface called wlan0 then you need to run something like this:

# cd /etc/init.d
# ln -s net.lo net.wlan0

Then, set something like RC_NET_STRICT_CHECKING="no" in your /etc/conf.d/rc 
and all the right things should happen when you boot up.

Sorry, not adequately clued up on this, to offer any reliable advice.  I know 
that the wpa_supplicant requires the iface to stay up, something which may 
not happen if dhcpcd goes down and takes the iface with it.  You may want to 
try adding an option like dhcpcd_wlan0="-o" in your /etc/conf.d/net to see if 
it makes any difference.  Someone more knowledgeable in network matters ought 
to advise here.

HTH.

Ok, I did it: it works!
But I continue to have some problems...
First, on boot time net.eth0 gives up and I must wait until timeout 
before that boot could continue.
Second net.wlan0 fails with a strange message, it says that no wlan0 are 
present on system to check hardware and driver. 
The strange thing is that after boot I had already network and that 
message:
WARNING:  net.wlan0 has started but is inactive
WARNING:  ntp-client is scheduled to start when net.wlan0 has started.
WARNING:  festival is scheduled to start when net.wlan0 has started.
WARNING:  sshd is scheduled to start when net.wlan0 has started.
WARNING:  netmount is scheduled to start when net.wlan0 has started.
WARNING:  samba is scheduled to start when net.wlan0 has started.

How can I solve it? Boot is too slow...

I found the problem! I used wpa_supplicant with this command line:
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf -B
- -B says to work as daemon, but it can't change keys and after my key 
expiration the system disconnect me.
Now it works fine.
Thanks,
Luigi

emerge ifplugd and read the comments about it in /etc/conf.d/net.example

Sorry I answer only now: I was not here!
Your command works good, now in boot time I don't wait about net.eth0
but net.wlan0 and net.eth0 seem not active, but the wireless works.
I found that my connection is not still stable.
dmesg is full from this kind of messagges:
zd1211:Mixed Mode
wlan0: Configured authentication algorithms:  Open system
wlan0: Drop encrypted: enabled
zd1211:Switch to Infra mode
zd1211:Mixed Mode

zd1211:STA_ASSOCIATED with 00:15:0c:24:bd:22
zd1211:Notify_join_event:00:15:0c:24:bd:22

And after same time (very irregular days or hours), I lose the signal 
but nothing notices it.
I can solve with 2 simple command: rmmod zd1211b and modprobe zd1211b
When I put on the module again, dhcpcd recognizes it and start a new 
connection.
What is wrong in my configuration? 
My /etc/wpa_supplicant .conf is:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
network={
ssid="MySSID"
proto=WPA
key_mgmt=WPA-PSK
pairwise=TKIP
group=CCMP TKIP WEP104 WEP40
psk="MyPassword"
priority=2
}
fast_reauth=1

Thanks,
Luigi

I'm not sure but it may have something to do with TTL and MTU sizes being 
different between your wireless router and your computer wifi card?

Assuming that is your zd1211 is your wireless card device I would comment out 
the mixed and infrastructure mode settings from the /etc/conf.d/net file to 
see if it makes a difference. 

If you still cannot find what's causing it I would suggest that you establish 
a basic connection to the router without passwd authentication, or anything 
clever and see if that holds the connection.  If the connection failures 
continue, then it may have to do with a hardware problem.  If the connection 
failures go away, then it is a configuration issue.

HTH.
