wlan0 ~ wifi0 connection problems

[MrChris]

Hey all

I know there has been a bunch of post re: something similar but i have spent the past 4 days trying to find a resolution for this problem, and have not no where.

to start off i have a toshiba satellite a105-s4014 it has an intel 3945abg card built in.

The problem is i cannot connect to the internet at all via an open access point

here is what i have tried so far:

wireless assistant - connection failed 
iwconfig wlan0 up - unrecognised wireless request "up"
iwconfig wlan0 essid linksys channel 6 
dhcpcd wlan0 - no response: ifconfig shows only loopback address

when changing drivers

modprobe -r iwl3945
modprobe ipwraw

my wireless assistant shows no networks

iwconfig wifi0 essid linksys channel 6 - set failed on device wifi0: operation not supported

now here is the tic all the air-ng programs work fine with no problems and wep, wpa cracking is a breeze.... i just cannot connect to a network.

If this has been resolved already and you know the correct thread to look into please let me know.... i know how annoying it is to have the same question asked a million times....

thanks in advance

wireless assistant - connection failed

Don't use wireless assistant.

iwconfig wlan0 up - unrecognised wireless request "up"

That should be ifconfig with an f.

iwconfig wlan0 essid linksys channel 6
dhcpcd wlan0 - no response: ifconfig shows only loopback address

Try this:

iwconfig wlan0 mode managed
iwconfig wlan0 essid linksys key off
ifconfig wlan0 up
dhclient wlan0 (or if you prefer, dhcpcd wlan0)

And To view networks in range:

airodump-ng wlan0

Using airodump will put your card into monitor mode, so always remember to switch back to managed mode afterwards with: iwconfig wlan0 mode managed.

iwconfig wifi0 essid linksys channel 6 - set failed on device wifi0: operation not supported

I've had the same problem with setting channel on my Alfa 500 mW. You don't need to set the channel if you give the essid. However if there's identical essid's in range, I specify the AP:

iwconfig wlan0 essid linksys key off ap 00:01:02:03:04:05

hey Virchanza thanks for looking it over after much reading i ended up seeing my mistake the whole ifconfig vs iwconfig... People that take the time to help us noobs rock and i really appreciate it. To bad there is no point system i can give you a star for or anything like that

double post

[Virchanza]

when specifying an essid for iwconfig, what do i do when there is a space in the name ex "linksys 01"

Use inverted commas:

iwconfig wlan0 essid "Monkeys live in trees" key off

By the way I have a quick Linux internet connection tutorial here:

Also, if you load the raw drivers, you're stuck in monitor mode. You cannot connected to an AP with them. So when you have wifi0, you can airodump/aireplay, when you have wlan0, you can connect/surf the web.
