PCI Wireless, set it up, can scan, but not connect

Terror · 03-01-2008, 08:25 PM

Hi all,

I've got Atheros wireless adapter on my PC, and a NetComm NB600W router (external).
I've installed MadWiFi and it works, but the problem is following:

I can scan and see the networks around (using KInternet), but i cannot connect to any of them. It says 'Error connecting to: MYLAN You are currently not associated with this access point' or something like this 20-30 secs after 'Connect' button was pressed.

Can you help me plz?
I've got WPA-PSK encryption

PS im a linux n00b
PPS running SuSE 10.0

Association is afaik done with

Code:

iwconfig $device ap $ap_mac

where $device is something like eth0 or eth1 and $ap_mac is the MAC address of the access point you want to connect to.

That worked, thanks

Now I can connect to the network, but i cannot "mtr" the router

Code:

mtr 192.168.1.254

it starts the mtr up, but i have no response from it (the last line it shows is only the table headers, like "lost(%)" or "sent"

Never used mtr but quick search says it's similar to ping, so you probably have to use a command line operator to specify the network interface to use (again eth1 probably, I assume by default it uses your ethernet card). Man page says:

Quote:

-a IP.ADD.RE.SS
--address IP.ADD.RE.SS

Use this option to bind outgoing packets' socket to specific interface, so that any packet will be sent through this interface. NOTE that this option doesn't apply to DNS requests (which could be and could not be what you want).

That should be the one but it suggest ip-address as the parameter. I'd think something like

Code:

mtr -a eth1 192.168.1.254

I could be totally wrong here, just suggesting.

For example with ping I have to use

Code:

ping -I eth1 whateverip

when connected with my wifi card.

mtr is working correctly, it was the firewall.
btw my interface is ath0

However, the KInternet says i am connected successfully to MYLAN, even if the password is wrong %)
Is this a "correct" way it behaves?

and now, when i rebooted, the firewall is down, but it doesn't work AGAIN. I mean it can see the networks around, i can connect (using random passwords), but the router does not assign me any IP address

kummiliim · 03-04-2008, 12:37 PM

That's what dhcp is for. I use dhcpcd myself:

Code:

 dhcpcd -d ath0

I don't know how to use the other common ones.

Terror · 03-05-2008, 04:03 AM

it's not dhcp, imho, coz

"mtr 192.168.1.254"

does not seem to send packets

Well, you can't send packets that you want returned if you don't have an ip addres. You mentioned that the router didn't give you one. Dhcp is how it gives the ip. The other cariant is setting the network settings manually- static ip.

Terror · 03-05-2008, 10:46 PM

ok, i'll try..

Edit:
dhcpcd seems to run in console, not as a daemon... quick look thru manpages did not show anything

kummiliim · 03-08-2008, 01:35 PM

It prints out some basic stuff with the -d flag and then goes to backround (ps aux | grep dhcpcd). The more important thing is did that help you establish a connection so you can use your program?

Terror · 03-08-2008, 03:47 PM

No, it does not print out anything, it just stays in the console -- does not go background. The "ps -A |grep dhcp" does not show it.
The only way to close it is Ctrl+C
