 |
|
Hi guys! I just got my IBM R40 yesterday, and I ordered it with a Cisco wireless card. Now, I've got some issues installing a driver for it. I'm using kernel 2.6.1, and the airo driver doesn't work for it, so I downloaded the driver from Cisco's website, and I get compilation errors. Is anyone getting this working? Please help! Thanks!

Which aironet card do you have? Is it the built-in mini-pci card? If so, then good luck. It's a real bitch to get it working. In any case, you usually have several options with the aironet cards. You can use the cisco drivers for them, but they'll taint your kernel. You can use the open-source drivers for the mpi350 (you can get from sourceforge), but they are pretty flakey.
However, if you are using a normal (non mini-pci) aironet card, I would think that you can use the kernel drivers. I, personally, had problems with my wireless NICs in 2.6.X so I'm hanging out in 2.4.23.
If you are trying to use the Cisco drivers with 2.6.X, I don't think that will work. I also don't think you can emerge the pcmcia-cs drivers in 2.6.X, but I might be wrong there.

I got the mini pci option, after reading on IBM's Linux page that it is Linux supported. Hmmm, that was a waste of $100 upgrade. I may just have to shell out the cash for a PCMCIA adapter, but i really don't want to do that! Thanks

It might not be all that bad. The cisco module works, but, I was never able to get it to work with wireless extensions (let alone wlan). So, I had to use Cisco's lame little gui to configure WEP and such. Check out mpi350-driver in portage. I don't think it works with 2.6, though.
The airo-linux stuff isnt' in active development, but you can check it out at: http://airo-linux.sourceforge.net/ Again, though, I don't think it works with 2.6.
I heard rumour that maybe mpi350 stuff will make it to the kernel, but I'm not holding my breath.

Hey thanks. I ended up downgrading to 2.4.24 and it works now with the Cisco drivers  It seems as though when I do multiple downloads that it has some problems, but nothing I can't work around. My only problem is that I need to find a patch to enable cpufreq with 2.4.24. Thanks!

Glad to help.
So, are you using the mpi350-drivers in portage? Are you able to set your WEP key and all that jazz using iwconfig? Or are you using the cisco gui?

I am using the Cisco GUI. It is challenging, especially after putting the system into sleep mode. Now, when you initially emerge mpi350-driver, modprobing the driver will result in an unresolved symbol, so I manually built the module and then cd'ed into the directory of its location and did 'insmod ./mpi350.o'. Now, I usually have to play with the utility and run dhcpcd mulitple times until I finally get a signal and get on the network. It is very annoying! But, with wrestling I can get it to work. Bummer it won't compile with a 2.6 kernel. Now, what is WEP?

It means Wired Equivalent Privacy. It's encryption for your wireless network. Although, it's more secure than nothing, it's not terribly secure. That said, you should probably enable it on your network. Otherwise naughty people could sit outside your house and monkey with your network.

Fabrice Bellet has been working on taking the work on the airo-linux sourceforge CVS and continuing/extending it. I've helped him get things jiving under 2.6. All that info can be found here. Hopefully that helps!

Yes, I just found a page of his http://bellet.info/~bellet/laptop/t40.html and under the wireless section I found a patch for 2.6.1-mm2. It works a little slow, but seems to be MUCH better than Cisco's module. I'm very pleased! I know have everything working on my new R40 except suspend to disk

Those drivers are friggin' awesome! How are you loading your essid and WEP key? Did you just put an iwconfig line in your /etc/init.d/net.eth1 script?

hey guys, i'm on a T40 and i have the minipci 350 internal. i also have a pcmcia aironet 4800 if i need it. I've been using linux for quite some time now, as i use it for work all day long, but one thing i have never had to do up untill this point is add an additional network interface. i'm running 2.6.1 right now, and would really like to get my internal wireless working. i've tried bellet's methods but have been unsuccessful. i've tried SOOOOO many different things and i'm soo about to give up, but that never seems to help. 
if anyone could either maybe walk me thru or even once i get home from work, i would gladly let someone SSH into me and maybe do a little screen action or something so i can see what needs to be done.
i'm just about on my hands and knees know begging for help....and i hate begging!! hehehehe
please let me know if i can post any configs of any sort for some help also.
thnx in advance,
mike |

I've got a working airo.c for you to use, I just don't have a page to upload it to. It seems to work well with 2.6.1 and 2.6.2-rc2. Give me your email, I'll send it to you! I discovered this after MUCH googling. It seems to work pretty good most of the time.

Okay, remove /etc/init.d/net.eth1 from the default runlevel. Then, I edited /etc/conf.d/local.start and added these lines:
iwconfig eth1 essid any
dhcpcd -t 15 eth1
It seems to work okay!

|

Hay Mike, so you are just trying to bring up your mpi_350 interface? Is that right?
Here's how I did it. The patches on http://bellet.info/~bellet/laptop/ are only for 2.6.1-mm2 in the 2.6 tree. So...
1. Get a copy of the linux-2.6.1 sources. You can get them from kernel.org ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.1.tar.bz2
2. copy that tarball to /usr/src. Then do | Code: | | tar xjvf linux-2.6.1.tar.bz2 |
to unpack it.
3. Now you need to get the mm2 patchset. Get the patches from
http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.1/2.6.1-mm2/2.6.1-mm2.bz2
and copy this file to /usr/src/linux-2.6.1. Then do | Code: | | bunzip2 2.6.1-mm2.bz2 |
4. Now, you need to apply the mm2 patchset. Do you this in the same directory. Just do [code]patch -p1 < 2.6.1-mm2[code] Hopefully there aren't any errors, because I can't help you if there were.
5. Now, you need to cd to drivers/net/wireless (or something like that) and you are looking for the airo.c module. When you find it, you need to download the airo.c diff file from http://bellet.info/~bellet/laptop/airo.c-2.6.1-mm2.diff to this directory.
6. Now apply that patch [code]patch -p0 < airo.c-2.6.1-mm2.diff[/code]
Now you should be able to cd to /usr/src/linux-2.6.1 and do a make menuconfig and go from there. After you rebbuild the kernel and reboot, you should be able to [code]modprobe airo[/code] and you should see a new interface when you do a [code]ifconfig -a[/code]. If you still have problems, let us know.

Howdy, I would just build everything in the wireless section as a module. Otherwise, make sure you build what Gentoo needs (devfs and the like), it should be like building any other kernel. Are you currently running 2.6.1-mm2? If not, then I think you should recompile the new kernel and then boot from it, just to make sure. I know that 2.6 can supposed load modules of other versions, but that's just one more thing to go wrong.

ok man,
i've done everything and still a no go..my light won't even come on 
you are talking about my internal miniPCI cisco350 correct?? sorry to be a pain, it would just be HUUUGE if i can get this working for me. thnx again d00d...
once again also, i can post any config file that may be needed!!

Light? I don't even think my mini-pci (mpi350) even has a light. Did you do a ? Did that work? Do a and see what it says. If you do an ifconfig -a, do interfaces show up? Check the MAC addresses. Does one of them match the MAC address information you are getting in dmesg?

right on the bottom of my monitor of the T40 there's a little light that should light up for the internal wireless....
yes i do a modprobe airo and i can do an lsmod and it's there.
the only thing that dmesg states in there about airo anything is this :airo:
Probing for PCI adapters
airo: Finished probing for PCI adapters
when i do an ifconfig -a only my eth0 which is my e1000 and my local loopback are present.
bummer huh?
heheheh |

Hmmm, that is exactly what happened to me when I used the unpatched airo driver. This is odd, it should have been found. I could just send you the correct, patched airo.c file if you still can't get it working. Under the kernel config, you did select the PCI/ISA airo driver, and not just the PCMCIA one, correct?

Hey jcmorris,
I wouldn't be able to tell you if it still works under windows because i've never once booted to windows on the T40. The day i got it the liveCD went into it and i removed their stupid litlte winbloze. MUAHAHAHAHHAHAHA
sry bout that..heh
ok...yes i did select both the PCI/ISA & the PCMCIA one
# Wireless 802.11b ISA/PCI cards support
#
CONFIG_AIRO=m
# CONFIG_HERMES is not set
#
# Wireless 802.11b Pcmcia/Cardbus cards support
#
CONFIG_AIRO_CS=m
# CONFIG_PCMCIA_ATMEL is not set
# CONFIG_PCMCIA_WL3501 is not set
CONFIG_NET_WIRELESS=y
do you think if you sent me youre airo.c file that it would work?? please don't tell me it's something as simple as that...  |

That looks okay. Now remember, under linux the wireless light only comes on when it is being used (ie after dhcpcd has been run on the interface). So not seeing it on after inserting the module is normal. However, if ifconfig can't detect the interface, then there is a problem indeed. What firmware version are you using for you card?
