Newbie have problems with WI-FI configuration

sergoint · 10-05-2006, 03:12 PM

hi all, this is my first question in this forum)
I am a BIG Newbie in linux so please help me to learn/understand what i can do.

so, i have router 3Com configured (i can surf in XP)
i have Wi-Fi EDIMAX ew7318Ug (usb connection)
I'm Working on SUSE 10.0
i installed the usb wifi so i can see it in the network devices.
i tryed to configure it in yast, but it seems that is not helping me because i can't surf.
what are the steps to make it work??
Thanks for all))

Can you ping anything?

Post the output of the following:
ifconfig, iwconfig, lsmod and lsusb

Let me guess... you have wpa tkip encryption set on your wireless router???

You need to install and configure wpa_supplicant. WPA-Supplicant is normally supplied with the SuSE distibutions, but there is no useful tool for configuring it. You may want to look at adding apt4rpm so you can use apt-get to install the wpa_supplicant and also apt-get a tool for help setting up kernel modules... I can't remember the name of it off-hand. Alternatively, you can search high and low for the step by step procedures of setting up wpa_supplicant by hand... not a very user friendly process...

The alternative is to look at Kubuntu... and install some of the wpa configuration and setup tools found in the universal repositories... I think you'd be much happier...

The only problem is Kubuntu's security model isn't the same as SuSE. Kubuntu by default sets up one user as an admin who can use sudo, and sets the root password the same... very, very bad security. Also, the installer tends to notproperly set up pre-configured /home partitions that you want to keep (not formatting them, just asking kubuntu to start using them as its /home partition).

hi again.
there is some movement:
1. when i used yast to configure the wi fi after i finished'i can't
see the rausb0 in ifconfig
2. when i using ifconfig to startup the device i get a link but can't surf.
3. i can send a ping to the rauter
4. a router don't have any encryption
5. there is the output from ifconfig,iwconfig

the fany thing is i have a connection, i can see the router, it shows me the strength and speed but i can't surf.
any ideas?

Are you able to ping the router?
And did you edit your /etc/resolv.conf?

In your /etc/resolv.conf should be the line:

nameserver IP_of_your_gateway(router)

e.g. nameserver 192.168.1.1

sergoint · 10-14-2006, 12:35 AM

i can ping to my router
how can i configure the /etc/resolv.conf??

2Gnu · 10-14-2006, 12:56 AM

From what you've posted, you have a driver loaded, the card is operating and is associated with the wireless router - all good.

What you lack is DNS information. Normally, /etc/resolv.conf is populated with the DNS server info supplied by the router when the client pulls an IP address. (I assume you manually set the IP address.)

You can get the DNS information from your service provider or, probably, from your router. Here's an example of how it should look (at least for my ISP):
search oc.cox.net
nameserver 68.4.16.30
nameserver 68.4.16.25
nameserver 68.6.16.30

Alternatively, you can use DHCP to obtain an IP and all should be well. On SuSE, I think the command would be dhclient rausb0.

when i start suse the rausb0 is not loaded
and i need to that: insmod rt73.ko
and after that: ifconfig rausb0 inet 192.168.1.65 up

how can i change the resolv.conf file?
how can i set dns? check the info of dns?

Fluxx · 10-14-2006, 06:37 AM

Here the script with which I start my RT73 usb wireless dongle:

Code:

#!/bin/bash
/sbin/ifconfig eth0 down
/sbin/iwconfig rausb0 mode managed
/sbin/iwpriv rausb0 set NetworkType=Infra
/sbin/iwpriv rausb0 set AuthMode=WPA2PSK
/sbin/iwpriv rausb0 set EncrypType=AES
/sbin/iwpriv rausb0 set SSID="my_essid"
/sbin/iwpriv rausb0 set WPAPSK="my_key"
/sbin/iwpriv rausb0 set SSID="my_essid"
/sbin/ifconfig rausb0 192.168.1.6 up
/sbin/route add default gateway 192.168.1.1
echo nameserver 192.168.1.1 >> /etc/resolv.conf
/sbin/iwconfig rausb0 rts 1401
/sbin/iwconfig rausb0 frag 1400

Try these steps one after the other and check what happens. You can leave out the steps concerning WPA2 encryption.

i tryed to configure like you say. when i send a ping to web site
it took more time but the the answer was the same: unknown host

Fluxx · 10-15-2006, 07:34 AM

You are able to ping your router?

And the nameserver in /etc/resolv.conf is the same IP like your router (default gateway)?

Fluxx.

sergoint · 10-15-2006, 09:26 AM

i can ping my router.
i don't no how to check/configure resolv.conf file

2Gnu · 10-15-2006, 09:44 AM

It's a text file, like most Linux configuration files. Edit it with your favorite editor.

sergoint · 10-15-2006, 02:15 PM

i have tried to open it via vi but it shows me like blank file
and i'm not shure is it a right.
if it is so i just need to insert there :
nameserver IP_of_your_gateway(router)

other thing is : my router don't have a dns or wpia supplicant

sergoint · 11-06-2006, 02:18 AM

hi all,
finally i finded a solution

after making all the staff that was wrote in readme file
i rebooted vance again and did the following:

cd /root/<rt73 ....>/Module
insmod rt73.ko
ifconfig rausb0 inet up
iwconfig rausb0 ESSID "3Com" (my router name)
dhcpcd rausb0

and it's works!!! )))))))))))))))

but, i need to make it run automatically when linux starts.
how can i do it???
thanks for all)))
