Wireless configuration and startup - The Gentoo way

Hi UberLord, what a great script :-)

Several people reported problems with WEP. Same here.
I'm pretty sure it isn't the wep key because when I type it manually:
iwconfig eth1 key 0011-2233-4455-6677-8899-aabb-cc
dhcpd eth1
then it works
To be sure it is not a timing issue I set: sleep_associate_eth1="5"

Here are the details (sorry for the long post):
1. plug in the card

well, this doesnt really have anything to do with wireless-config, but perhaps anyone can help me.

i'm using ndiswrapper for my builtin broadcom wlan card. i load the ndiswrapper modul through /etc/modules.autoload/kernel-2.6 during startup but i do not start net.wlan0, but wlan0 is up after startup. why is this and how can disbale this?

another thing is, that i want to use ifplugd monitoring eth0 for plugged-in cable and to change to wlan when no cable is plugged in and the other way around. i changed /usr/sbin/ifplugd.action to start net.wlan0 on unplugging the cable and to stop it on plugging the cable in again. it does work most the time, but sometimes i cannot ping servers on the internet and cannot visit websites anymore although i can still use icq. does anyone have an idea what could be wrong? nameservers are the same for both because lan and wlan is bridged. both devices are configured using dhcp.

thx a lot and sorry this does not have very much to do with wireless-config, but i think the people watching this thread do have the most knowledge when it comes to wlan.

@zaai
The key you are entering the key in the config file and the way you are typing it on the command line are different - you have the keyword open at the front. Make the entry identical after the "iwconfig eth1 key" bit you enter and it should then work.

If the script output (which you didn't post) shows WEP being enabled then it has enabled it - or tried too.
If there's an error with the script - this is the line that would be causing it

Try the shiny new 0.5.1 - it fixes quite a few problems that I missed :/

The shiny new 0.5.1 broke my wlan when I upgraded from 0.4.10.
I have a AP with hidden ESSID. 0.4.10 used preferred_aps to get the correct ESSID and used key_ESSID to set the WEP-key.
0.5.1 tried to connect directly with the AP, identifying it by it's MAC-address. It connected without WEP, and the dhcp-request timed out. Changing key_ESSID = "..." to mac_key_MAC = "..." solved the problem. The MAC is automagically mapped to the correct ESSID.

[CORRECTION]
The MAC is _not_ automagically mapped to the correct ESSID. I had to set
essid_MAC = ESSID
[/CORRECTION]

Cya, Ed

PS: Oh, thank you for wireless-config, oh great Uberlord! I praise you

I'm having problems connecting to a WEP-enabled managed wireless network.

I see the following when net.wlan0 executes:

Great, the 0.5.1fixed the upgrade problem!

The CVS version of madwifi-driver didn't fix my connecting problem. I still cannot connect to my DG843G AP. I've read things like "the madwifi-driver doesn't cope with DG843G" so I tried to upgrade the firmware as well. I can connect to another AP, so it must be true?

Is there any other driver that works with the Atheros chip?

I'm trying to edit /etc/conf.d/wireless, and not sure wat to do...

# Remember to change eth0 to your wireless interface which may be
# eth0, eth1, wlan0, ath0 - you get the idea. If you're not sure
# you can type "iwconfig" at the command prompt and it will tell you which
# interfaces are wireless.

iwconfig gives me this, though:

lo no wireless extensions.

eth0 no wireless extensions.

hi,

this script is really nice but i got a small problem with it. my setup is an ethernet adapter at eth0 and a wireless adapter at eth1. everytime i run

# /etc/init.d/net.eth0 start

i get the following:

* Running preup function
* Wireless extensions not found for eth0
* Bringing eth0 up (192.168.6.20)... [ ok ]

looks for me like the default gateway doesn't get set. the eth1-script works without problems (sets gateway). i figured out that only the last gateway="ethX/...."-line in /etc/conf.d/net is used.

the important part in the /etc/conf.d/net looks like this:

# For setting the default gateway
#
gateway="eth0/192.168.6.1"
gateway="eth1/192.168.7.1"

am i doing something terribly wrong or is this a bug? :>

thanks for your replies.

Is there any way to set it to connect to the AP with the strongest signal? I'm trying to connect to my schools network and it sees 5-6 access points. The one it connects to though, it gets signal quality of like 10/90, even though I'm right next to it.. then it cuts out. Maybe you could incorporate that into the next build?
