dwl-650+ on dell latitude laptop

danilo287 · #1 21st July 2005, 12:05 AM

first of all im new to linux so if the help is someone detailed that would be greatfully appreciated. I am trying to get my dwl-650+ network card up and running on my dell latitude(1ghz p3). i was using the help of houseofcraig.com. I was able to get the driver installed and run ./start_net with out a problem but i cant seem to ping anything other than my self. My ip address is 192.168.0.101 and when i try to ping my wireless router (ping -c 4 -I wlan0 192.168.0.1) i get:
ping 192.168.0.1 (192.168.0.1) from 0.0.0.0. wlan0: 56(84) byes of data.

---192.168.0.1 ping statistics ---

Some other info that might be needed but im not sure:

can anyone tell me what i can do from here

Results from:

netstat -rn

may provide useful.

Are you using DHCP to get your IP address info? If so then you have connectivity with the router. It may be that your router does not respond to icmp pings. If the default gateway is not correct you would not be able to get outside the LAN. If you have other devices on your LAN try pinging them.

when i type netstat -rn i get:

I am using DHCP to get my ip address. As of right now i have router connected with a wire to my downstairs computer and another computer upstairs using a wireless dlink dwl 520+. Both of those computers are running windows XP.

2 more things. The first one is what exactly is ESSID, i tried to set it as default and any in the start_net file. Also when i went to the troubleshooting section of http://www.houseofcraig.net/acx100_h...rouble_pinging it said that i should try tying ifconfig wlan0 up, which didnt return anything, then i typed iwlist wlan0 scan and got:
wlan0 no scan results. I dont know if this information is usefull at all.

Hi danilo287,
Has your wireless card associated with your access point yet? You can check this with the following command (can you post the output of this command as well, minus your wep key (if any) of course):

Code:

iwconfig wan0

What version of the driver are you using?

kg4cbk · #6 21st July 2005, 01:27 PM

The indications are that your wireless card is not associating with the access point. You do not have an IP address or default gateway assigned to your system yet.

Ignore the 169.254 entry that is for the zero configuration stuff which does nothing.
Also ignore the 127.0.0 entries that is the loop back address.

ESSID is a label or name you assign to your access point. You need to match this on your computer and you should see it listed when you run:

iwlist scan

unless you have set the access point to not broadcast your ESSID.

You should probably start at the beginning. What chip set does your wireless card have? You can get that info by running:

/sbin/lspci

iwconfig wlan0 before i run start_net:

iwlist scan:

my card has the TI acx100 chip @ 22mbp

kg4cbk · #8 21st July 2005, 07:20 PM

Are you using ndiswrapper, driverloader, or native drivers?

I am not familiar with the TI acx100 chip set.

The output above indicates the encryption key is turned off.

Is your access point setup to use WEP?

And what is the ESSID set on the access point? This also appears to not be set on your wireless interface.

ifconfig -a would also help to diagnose this.

danilo287 · #9 21st July 2005, 08:01 PM

im not too sure what you mean when you say ndiswrapper, driverloader, or native drivers. I used the acx firmware from http://www.houseofcraig.net/acx_firmware.tar.bz2 if that answers the question. I have WEP turned off on my access point. I havent changed my ESSID on the access point so it is 'default', do i have to give it a name for it to work?

Hi danilo287,
Are you trying to connect to an access point? If you are, the reason that you are having problems is that the start net script seems to be placing your wireless card into ad-hoc mode (this driver must be set to managed mode for it to be able to connect/see any access points).

Can you paste the part of the script above where it says do not edit below this line (minus any wep key you may be using).

kg4cbk, He is using the native ACX drivers (ie, they get compiled into a kernel module).

i finally got it to work i formated the whole hard drive, installed FC4 and did it all over again and it works now, but i just have one small problem when i try to get it to work as a regular user, root works fine...

i tried to run ./start_net again and i got an error saying
which: no insmod in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin/:usr/bin/:/bin:/usr/X11R6/bin:/home/dan/bin)

and now simple commands like iwconfig and ifconfig dont even work?

tsukasa_au · #12 24th July 2005, 03:45 AM

Hi danilo287,

Make sure you are runing these commands as root. Also, if you are using the su command to become root temporarily, that your have to use:

Code:

su -

notice the dash at the end of the command (it will make sure that you have access to the commands).
