Linux Internet Connection

Ryan10 · 09-07-2010, 09:00 PM

So i have installed linux 13 OS from a CD and i have it all working now but am a bit stuck on how to connect to the internet. Im sure its an easy fix but not for me.

Thanks Ryan

Im sure its not that complicated

Linux 13.05 what? Which distro? What type of ethernet card? What type of computer?

If you are trying to connect with wireless, try a wired connection, even if it means temporarily stringing a cable across the floor or moving the computer to another room.

Hook it up, reboot, then try pinging a site, such as yahoo.com.

(You may have to be root to run a ping.)

If you connect with a wired connection (and you likely will), that narrows the problem to your wireless. Run the command ifconfig -a as root and post the output.

The lspci command should tell you what type of ethernet card you have (if it is a USB card, try lsusb).

Once again, you should be root to do this type of trouble-shooting.

It shows my ethernet controller as Realtek Semiconductor

Well it works now if i plug it in directly through ethernet..but how do i keep it that way when i want wireless

Still can't figure out how to make it work with wireless

Kenny_Strawn · 09-07-2010, 10:29 PM

Need more details. What kind of wireless adapter do you have? Here's what I suggest:

Plug the Ethernet in and then run:

Code:

sudo apt-get install ndiswrapper

This will install NDISWrapper, which allows you to use the Windows driver for your adapter. Then, just insert the Windows disk for your network adapter and you're good to go with wireless.

Ryan10 · 09-07-2010, 10:40 PM

Whats the "Windows Disk" exactly?

Ryan10 · 09-07-2010, 10:52 PM

that code didnt work at all so i dont know what to do now

I believe ndiswrapper is unnecessary as there is a native linux for your wifi device. This driver is most in kernels now. Can you answer the following:
1. What kernel are you using? If you don't know post the results of

Code:

uname -r

2. I believe your driver is ipw220. If your kernel has this driver it will be here: /lib/modules/{your kernel number}/kernel/drivers/net/wireless/ipw2x00/ipw2200.ko. Do you have this driver?
3. If 2=yes then is the driver installed? If you don't know, what is the output of this?

Code:

lsmod |grep ipw

If lsmod finds nothing then your driver isn't loaded so we will know what kind of help to give you. If the driver is loaded then we will also know what kind of help to give you.
ciao,
jdk

This last line means that you don't need ndiswrapper, as the card is already recognized. Try running the following commands:

Code:

[root@Slackware13:/root]# iwconfig wlan0 txpower on
[root@Slackware13:/root]# iwconfig wlan0 essid <network name> key <encryption key (if you have one)>
[root@Slackware13:/root]# iwconfig wlan0 commit

If that last command fails, try configuring the wireless from X.

Oh wait: You don't have X on a Slackware Live CD! Never mind...

LQ has a helpful wiki article which may be your full solution.

http://wiki.linuxquestions.org/wiki/Wireless

Type iwconfig without any arguments in the Terminal to figure out which device has a wireless extension. If a device shows up then follow the wiki articles for configuring it to your wireless routers settings, otherwise post back here and we'll attempt to troubleshoot what is wrong with your card.
