Just can't figure this out (wireless)...

**marinebro0306** · 08-29-2006, 02:06 AM

Hi,
I finally started running Knoppix Live CD, and everything works great with one exception: I can't connect to the internet. I tried everything, but to no avail. This is wireless, and the router is a D-Link DL-624, and the thing in the recieving end is a Linksys PCI card (B). I ran ifconfig, and this was the result:

Code:

eth1
Link encap: UNSPEC HWaddr 00-01-08-00-20-01-39-08-00-00-00-00-00-00-00
inet addr: 192.168.0.1  B cast: 192.168.0.255  Mask: 255.255.255.0

RX bytes: 0 (0.0 b)  TX bytes: 3672 (3.5 KiB)

eth2

RX bytes: 29007 (28.3 KiB)  TX bytes: 29007 (28.3 KiB)

I've tried several different things, but nothing works. Can someone please give me a step by step tutorial as to what do do?

Thanks in advance!

You cannot assign the same IP address (192.168.0.1) to two different network adapters. What's the output of

Code:

ifconfig -a
iwconfig

**marinebro0306** · 08-29-2006, 03:14 PM

OK I did those two, and these were the results: (and for the sake of my hand while copying it down a lot is abbreviated, but understandable)

ifconfig -a

Code:

eth0:
Link encap: Ethernet  HWaddr  00:06:25:1B:AD:5C
Broadcast multicast  mtu: 1500  metric: 1
RX packets, errors, etc: all 0
TX: all 0
collisions: 0  txqueuelen: 1000
RX+TX bytes: 0
interrups: 9  base address: 0x4000

eth1
same as eth0, except:
HWaddr  00:01:08:01:08:6A
interrupt:  16  base addr: 0x2c00

eth2 -00
same as eth0 except:
Link encap: unspec
HWaddr: 00-01-08-00-20-01-39-08-00-00-00-00-00-00-00
TX errors, dropped are 4
no line for interrupt/base addr

lo
Link encap: local loopback
inet addr: 127.0.0.1  Mask:  255.0.0.0
inet6 addr:  ::1/128  Scope: host
up loopback running MTU: 16436  Metric: 1
RX+TX packets 62, all else 0
coll.+txqueu: 0
RXbytes: 4300 (4.1 KiB), same with TX

sit0
Link encap: IPv6-in-IPv4
NOARP  MTU: 1480  Metric: 1
RX+TX all 0
coll+txqueu: 0
RX+TX byes: 0

And for iwconfig:

Code:

lo: no wireless extensions

eth0: IEEE 802.11b  ESSID:off/any  Nickname:  "Broadcom 7301"
Mode: managed  access point: invalid  Bitrate=1 MB/s
RTS thr: off  Fragment thr: off
Link quality, signal level, noise level: 0
RX invalid nwid, crypt, frag: 0
TX excessive retries, invalid misc, missed beacon: 0

eth1, eth2, sit0: same as lo

Keep in mind that this was after a reboot.
Thanks.

access point: invalid

This doesn't look good, but we can give it try. Log in to the router and disable encryption (we can deal with that later).

Code:

su
ifdown eth1
ifdown eth2
iwconfig eth0 essid "mynet" mode Managed channel X
dhclient eth0

mynet= ESSID of your WLAN
X=numeric value for channel

By the way: You don't have to type, just use copy & paste.

Few questions: How do I log into the router and disable encryption?
How do I determine the ESSID?
How do I determine the value for my channel?
And all 5 of those lines are seperate entries, right?

I'm not an idiot when it comes to computers, I'm just used to the automation of Windows, and how it determines all this automatically. Bear with me, this is all new to me.
Also I can't copy and paste cause I'm writing this on a different computer...and I would do it on the one with Knoppix on it, but I cant connect to the internet and it takes to long to constantly switch OS's.

Thanks again for your patience.

If the OP could give a bit more info on the hardware setup, for example the output of: lspci -v
, we could get a better idea of whats going on, Also the output of lsmod, to see if drivers for a wireless device have been installed.

Do you have a USB thumb drive?

Yeah, didn't think of that.

**ockham23** · 08-29-2006, 05:08 PM

Few questions: How do I log into the router and disable encryption? You need a network cable to connect to it and a password to log in.

How do I determine the ESSID? After login, you can retrieve the router's settings.
How do I determine the value for my channel? Same as above.

And all 5 of those lines are seperate entries, right? Yes, each line is a separate command.

OK I did those two. The outputs were rediculously long, so they are condensed. I will remember to put them on a thumb drive from now on

Here is lspci -v
