thanks for the guide, im having a few problems with the make all command though, when i try it i get the following.

Any Idea's? Im running Fedora 2 with everything updated possible....
Any assistance would be greatly appreciated!

Ok fixed that part by just making a folder called .tmp_versions where it was looking but now i get another error when i try and run make install.

Tried making a folder like before but didnt work.

Any suggestions?

I got it installed just fine, did the modprobe and am now trying to configure it (gentoo, do-it-yourselfer) I tried ifconfig and nothing showed up for wlan0, so I tried ifconfig wlan0 and got some data saying it was ethernet, but no hardware address, I tried giving it an ip ifconfig wlan0 192.168.0.22 and got: SIOCSIFFLAGS: No such device
I have configured the wlancfg and wlan-mySSID (I replaced it wit my SSID) and gave it the wep configurations, but it just does not seem to work (and yes I did load the module)

anyone who has made the ma111 working with the "how to"?why I can't?I used red hat linux whit kernel 2.6.3

exodist

the tutorial told me where to get the driver, the linux-wlan-ng project, from there I figured it out on my own (with some frustration) but then again I am unorthadox and a gentoo user with 5 years of experiance telling me to do it myself and not use packages or utilities :-D

first I downloaded the driver and ran the script liek mentioned and it installed the prism2_usb module. I then would do modprobe on the driver (modprobe prism2_usb) and would get my wlan0 device, but it didn't have a mac address, and I was unable to use it weather or not it was on a network with wep encryption. you are probably stuck here as well, type ifconfig wlan0, is there a mac address? if not that is the problem.

to fix it in gentoo:
use emerge to install linux-wlan-ng: emerge linux-wlan-ng

do not uninstall the manually installed driver however, emerge fails to place some needed files in /etc/wlan (grrrr) not uninstalling the manual one will fix this.

then to get the card initilized run /etc/init.d/wlan start
to make initilize at boot type: rc-update add wlan default
that will initilize the card w/ no wep encryption and it will connect to the first open network it finds. you can use ifconfig wlan0 IP to set the cards ip, or you can use dhcpcd -t 10 -d wlan0

if you need wep encryption you need to configure /etc/conf.d/wlan.cfg, it also has further instructions regarding this inside the file.

here is a copy of the /etc/init.d/wlan for those not using gentoo, I doubt it will work as-is in another distro, but it might give you an idea.

I am kind of new to the wireless part of linux I have a MA111 wireless usb card. I was wondering what kernel I need? I am using 2.4 with redhat 8.0. Do I need to upgrade to 2.6 or should it be ok with 2.4? If someone knows an easier version of linux to get it configured, please let me know?

Thanks in advance

on the first tutorial i tryed to unzip the tar.gz file to /usr/src but it said i need permission to do this so i tryed to do it in the terminal but what is the command for unzipping something to somewhere like /usr/src?

exodist

you need to be root:
su root
password:

then go to the directory where you want it to extract to (/usr/src)
cd /usr/src
then type:
tar -zxvf path/to/file/thefile.tar.gz
that will extract it intot he current directory. (/usr/src) not into the directory where the file is located.

explination:
tar is the command used for archives (.tar)
gunzip extracts .gz files
bunzip2 extracts bz2 files
however when you have a .tar.gz or .tar.bz2 the tar program can take care of the gunzip or bunzip for you
tar -z file to handle gzip (.gz)
tar -j file to handle bzip2 (bz2)
the -zx means extract from gzip
the -zxv ads verbose so you can see what is happening.
the -zxvf adds something, I am not sure what the f flag does atm, look it up (tar --help) I know it was important and is screwy if you leave it out.. been using it 5 years now and never looked it up.

exodist

looked it up, f needs to be at the end, f means use the file that follows it

tar -f filename
tar -zxv[f] filename the filename must be immediately after the f with a space between.

tar -zfxv filename will nto work it will try to find xv as the filename (I think)

Wow, installing a device driver in linux only takes 7 steps? Gee, it's practically plug & play!

But I'm having a teensy problem doing step one. How to I get the source code for my kernel? I have Fedora Core 2. I do not know how to determine the kernel version, but even if I did, I wouldn't know how to get the source.

Honestly, what kind of OS requires the kernel source just to use a device driver? ...

exodist

Qwertie

Great. Now how do I figure out what version kernel I have?

exodist

lol good question, I always compile my own and thus know what version, why not just use the most recent version?

Qwertie

And while I'm at it, does anyone care to explain why exactly the kernel source code (40MB?!) is needed to build a device driver?

Also, well, I sort of have to figure out how this driver works. Does anyone know of a good website about the linux device driver model?
