Too complicated and obscure way of configuring the wifi, I would say.

Easiest way if writing a init script which ALSO permits selecting multiple acess points with multiple settings.

Erm, the script allows multiple access points (preferred_aps=( ESSID1 ESSID2 )) and mutplite settings (config_ESSID1=( dhcp) config_ESSID2=( 192.168.0.2/24 ))

As for being complication and obscure I say FOO

Without any settings we automatically connect to the strongest Access Point or Ad-Hoc node (well, automatic to ad-hoc doesn't work in baselayout-1.11.8, but it works in CVS)

So most people will just need to configure a preferred_aps list and any WEP keys needed. That's not hard or obscure imo.

Hi there, after download some stuf or after a long period of time my wireless card seem to disconect and reconect again, and seems that after a while do the same ?

anyone know what is wrong with my conf or card ???

lspci |grep network

May not be your card - I have similar issues with our AP at work - it needs a hard reset once a week or so.

I have a similar AP at home, which requires a hard reset once a month or so.

Check to see if there's updated firmware you can use.

Ok I got everything working after I ran ( rc-update add net.wlan0 default ) it only shows the output in init if it fails. When it comes up and gets a dhcp address it has no output not even ( * Starting wlan0 )

Any ideas?

Hello,

Just installed Gentoo and I am having trouble with my wireless. I have had it setup several other times with mandrake/fedora/ubuntu/slack, but Gentoo or my lack of knowledge of Gentoo is giving me fits.

I have tried to download the latest wireless conf "baselayout" but everytime I do I get this....bash-2.05b# emerge -av sys-apps/baselayout

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild R ] sys-apps/baselayout-1.9.4-r6 -bootstrap* -build -debug -livecd (-selinux) -static (-uclibc) 197 kB

Total size of downloads: 197 kB

Do you want me to merge these packages? [Yes/No] no

I followed the instructions in the thread that is now locked. I was wondering if someone could maybe give me easy step by step instructions.

Yes I have emerged the madwifi drivers and the wireless tools.

Thanks ahead of time.

Edit your /etc/portage/package.keywords file

You may need to create it

Add to it the following lines

Fatboyjim,

I added those lines, (already had the madwifi stuff) and I still get the same response from emerge.

If you're using AMD64 then you need to replace ~x86 with ~amd64

Same applies for other arches

I've been trying to set up a laptop for both fixed and mobile work. As a test I have 2 APs set up, one hidden and one broadcasting; the non-broadcasting is my preferred.

I want my machine to connect to my non-broadcasting AP if possible, then fallback to ANY if it can't connect.

If I choose "forcepreferred" it will connect to my AP fine. When I turn off the preferred AP it doesn't connect to anything (expected).
If I choose "forceany" it will always connect to anything open first instead of the non-visible preferred AP. Guess it really is quite literal

Is there any way to enable some sort of "forcepreferredthenany" mode? Some way to force (non-broadcasting) preferred first, then search for others on failure?

I'm running baselayout-1.11.7-r2 and gentoo-dev-sources-2.6.10-r4. I have wireless working correctly, but the scripts in /etc/init.d/ don't seem to think that my wireless connection provides a network. For instance, when I have net.eth0 (built-in 100BaseT adapter) stopped and net.eth1 (Orinoco wireless) started, starting cupsd will bring up net.eth0 again. If both eth0 and eth1 are running, then all network traffic goes to an unplugged eth0, and nothing works. The behavior isn't terribly consistent either, since the first time I bring down eth0 nothing else stops, but if I bring it up and back down again, BOINC and Postfix will stop. Currently, I have net.eth0 in the default runlevel and net.eth1 in no runlevels, and I'd like to keep it that way.

Is there any way to fix this behavior? I'd really like for my computer to realize that my wireless card provides network access.

That problem is fixed in sys-apps/baselayout-1.11.8 which was put into portage a while back

Using gentoo-dev-sources-2.6.9-r13 my wireless card worked perfectly

After upgrading this morning to 2.6.10-r4 it no longer works

The card does have lights on it (after re-enabling the PCMCIA stuff in menuconfig) but a scan for access points says there are" no access points found for ath0"

Any ideas what I need to enable/reinstall?

Thanks
Jim

No idea - madwifi works fine on my AMD64 box with that kernel version

Maybe you could try reemerging wireless-tools or madwifi-driver ?

fatboyjim · Apprentice Joined: 12 Jul 2004 Posts: 227 Location: UK

Should have mentioned I've already re-emerged madwifi-driver

I'll re-emerge wireless-tools now then, thanks for the tip

Jim

I just finished doing a reinstall of Gentoo on a new hd and desided to use the directions on the wiki to setup wifi. So I updated the baselayout, installed madwifi/wireless-tools, added modules to auto load list, made /etc/conf.d/wireless as suggested and rebooted into the new install.

The problem is that when I try "iwlist ath0 ap" no accesspoints show up. Also strange, when I try "iwlist ath0 scanning" I get an error saying the interface does not support this feature, or something to that effect.

I'm using the same madwifi-driver and wireless-tools versions on my old setup and my accesspoint shows up. The two major changes with my new install are the baselayout and I'm using udev only now. Any ideas?

Problem for me with new kernel turned out to be "Module Unloading" was enabled in the kernel.

Turned this off and all was well again

Cheers
Jim

I got things working... just not with the net.lo that comes with baselayout-1.11.8

. I copied my old net.ath0 (a copy, not a symbolic link, of net.lo from baselayout-1.9.4-r6) and everything works fine again.

I'm not sure how to figure out what went wrong with the new version of net.lo. UberLord if there is anything I can do to figure it out let me know. Until then I guess I'll just use the old one :roll:

.

Oh and I removed module unloading from the kernel, never a problem before with it, but that had no effect.
