unable to connect wifi with 802.11 b/g
 
I have a compaq presario. I am a newbie to Linux. I cannot connect my wifi. The indicator won't light up and I just get an error message sayin network is down on interface pppo. There seems to be some abswers out ther, but they are more advanced than I am.

What adapter do you have? What program are you using to connect? Most likely, it's looking at the wrong interface, wifi is most often seen as wlan0, not ppp0 which would be a dial-up connection.

Search the forum of which distribution you are using, and look
at any documents included on your installation CD/DVD. We can't
help you at this point without asking you 20 questions. Also,
Google for How To Ask Questions The Smart Way, by Eric S. Raymond,
and read that article to understand a bit more about this Linux
culture which you have wandered into.

Sorry I can't be of specific help to you with this post.

i have searched the forum and haven't got a clear answer. I am new to linux and don't quite understand everything. Thats why I thought a forum for newbies would explain things in simple terms. I am using mandriva spring 2010.1. and still cannot connect. I do not have windows on the computer. When I go thru the contol center and try and set up a wifi connection I check select file in the drakconnect window. now to pick a file. I tried different ones and nothing works. But then I don't know what I'm doing. Guess Bill Gates is a billionaire because of all the dummies like me.

lol i'm a n00b at this as well, took me well over a week to get my wireless working on linux.

i do know there is a couple of things you could do or try..

you'll probably need to download the driver for it off the website for who makes your wireless adapter.

there is also a something-wrapper program you could try using (you'll need the driver for it).

can anyone explain this better?

sevymt 07-21-2010 08:27 PM

I thought I downloaded the right driver..but I'm not sure and then don't know if I installed it in the right place. Windows does so much of the work for you. This you have to do alot yourself and its not clear to me how. Its like the answers are telling you how to drive, but no one tells you how to start the car! LOL!

vansugar24 07-21-2010 08:31 PM

sorry im not on linux right now so i cant walk you through this but go to your download manager and look for something close to

ndsiwrapper - i believe that might help just check the info on it..it should relate to connecting to the internet

sevymt 07-21-2010 08:44 PM

I thought ndsiwrapper was only used if you still had windows installed on your computer and wanted to link the driver from windows to your linux software.

It was not meant to imply that you are a dummy. However, Windows
created an entire industry of people who don't read for themselves,
not to mention the security industry because of their poorly coded
software.

Please read that article suggested, even if you find it offensive.
That will explain the mindset of Linux users who work with this OS
every day, and why you can't just say "my wifi won't connect" and
expect someone to help. There are too many different Linux distros,
and they do things in many different ways. Search the website of the
one you're using for documentation, search Google, <Linux> Google,
and the LQ forum for your distribution.

For instance, my distro is Slackware, and yours is about as different
as mine as night and day.

I would like you ask you certain questions before I can be of any help.
Your Distribution
Your laptop make and model
The wifi adapter that is built in.
What have you tried before.

Also if you can help a bit more like paste the output of iwconfig command here in Code tags.
In addition to this, if you can lay your hands on Ubuntu 10.04 Lucid Lynx Live CD and run it and see if your hardware is detected.
And one more thing, are you seriously thinking of trying out Linux? I mean to say, you ready to answer the questions here? Or you think we can peek into your mind and read everything?

sevymt 07-23-2010 07:24 AM

Wow. You Linux people sure can be condesending. I feel as if I'm being thrown into the lake and told now learn to swim or drown! I really was serious about using this operating system. I am not that computer savy. I can work around windows more than most I know but that isn't really saying much. The problem is I don't understand most of the jargin and references you use and don't know where to find the them in the program. I'm a big directions reader. You may find it hard to believe but I research for a living. But I start at the beginning..I can't seem to find point "A" . the suggestions that are thrown out there don't even make sense to me. One suggestion was "paste the output of iwconfig command here in Code tags" I don't even know where to find that or what it means. I've seen it done in other forums but have know idea where they got it from. I came to the newbie forum because I thought the explanations would start at the ground up. I thought of purchasing a distribution, hoping it would have detailed instructions and support, but then I'm not sure which one and if it would have the support I was looking for. I can see why Linux is not as big as windows. You need an entry level for people to learn from. Perhaps I just got in over my head and this system is just for the "computer geeks", as an aquaintance of my son's referred to himself. And yes I would be asking him for help except he broke up with the girl who was in the circle of friends and doesn't come around anymore.
My computer is Compaq Presario V5000, has AMD Turion 64 mobile, processor ML-34 1.8 , 1BB L2 Cahe, wireless is airforce 54g 802.11b/g, wireless LAN with 125 HSM , speed booster support . Don't know what all that means..but I wiped the computer and installed Mandriva Spring 2010. Should I try a different a different distribution? I was on a Linux website that did question and answers and then gave you a list of suggested distributions to suit your needs. I just want to use this laptop to surf the net and music. I'd appreciate any help anyone is willing to offer, and if not thats fine too. But for now I'm loading up my horse and going camping in a dead zone. I'll be back sunday night trying to figure it out again. thanks.

You should have better used quote and code tags. This whole one paragraph is difficult to read and understand. And tedious too. Open a terminal or command line windows and type iwconfig there. If you are not sure where to find terminal, you can type Ctrl+Alt+F1 or F2 or F3 and log in using username and password and then type it there.
You can usually find terminal in Application > Accessories or Application > System tools depending on the distribution.
And if you are not comfortable with with Mandriva, you can download Ubuntu and try it without installing on the computer. It will directly boot off your optical media and you could use just like any installed system without installing it on the hard drive. And if you find it attractive and accessible, you can then go on and install it.

these commands are to help us to know what your system thinks is installed (not necessarily to get you connected).
Code:

lspci # will tell us the pci devices you have in your system.
lsusb # will tell us the usb devices you have in your system.
ifconfig # will tell us what network interface cards you have turned on in your system.
ifconfig -a # will tell us all the network interface cards you have in your system.
iwconfig # will tell us which of your network interface cards has wireless capability

now that we know that, this should get you connected:
Code:

sudo iwlist device scan # this will use the device interface (that from the above command, we found out has wireless capability) and scan for wireless routers that are accessible.
sudo iwconfig device essid "myssid" # assuming no security, use that device to connect to your router.
sudo dhclient # will attempt to get ip-address, subnet mask, dns server information automatically from your router assuming dhcp is turned on on your router.

also, please post the contents of cat /etc/network/interfaces
and /etc/resolv.conf should contain your dns server.
depending on if ifconfig returns the name of your device, you mite need to turn it on by doing something like: sudo ifconfig device up
you can also run lsmod to see if the wireless driver module is plugged-in.
