Wireless card working great.... but no internet???


hi there

I'm not a total Linux newbie, but this is my first tryout of Suse I've installed Suse 10.0 and finally (after a fair few problems) have it all working.

I have installed ndiswrapper to get my Broadcom radio card working and have followed the excellent instructions at sourceforge to the letter.

My kernel is installed, ndiswrapper installed, correct XP drivers installed and as far as I can see it is working! The output from iwlist, iwlist wlan0 scan, and from iwconfig wlan0, are posted below. My computer is a compaq presario laptop and the radio network light now lights up and as you can see below my radio AP is recognised (essid - 'nerdnet@no5'). this all comes on at boot-up and I'm ready to go.... BUT

I'm not able to surf the 'net! Both webbrowsers tell me that they can't connect. Mozilla Firefox is set to "direct connection to the Internet" but isn't connecting. Yes my WEP key is correct (I've checked it twice!), so what am I doing wrong?? I think I've done everthing correctly, but suspect that I have missed out some final step somwhere.

Why does my iwlist wlan0 scan give a link quality of 0/100, whereas the iwconfig and iwconfig wlan0 printouts show link quality as 100/100???


Any ideas folks??

Thanks
adrian

did you do
Code:
dhclient wlan0
u didn't mention if u "started" the wireless tools that make all this stuff work. you do this with dhclient wlan0.

also, change your security mode to restricted instead of open, just to see what happens. i used to use open too, but once u add a WEP key, according to the man pages, it's restricted. don't think that is what breaks it, but who knows.

thanks for the answer... and I'm probably going to find out I'm doing something totally wrong now but i got:

linux:/home/adrian # dhclient wlan0
bash: dhclient: command not found
linux:/home/adrian #

So something wrong there then! I am still a linux newbie though so I'm not sure what or why.


I do know that my radio card is working though as I am now at work now and a quick 'iwlist wlan0 scan' shows that the Proxy network here "WAVELANNET" is picked up as soon as I turn on my laptop:


linux:/home/adrian # iwlist wlan0 scan

The signal is 0/100 though but I don't yet know how to log on as a user to this network using Linux, although I can in Windows.

i just went back through my notes i had a simalure problem wiht my ma111 on my linux box a year ago i had dhcp enabled and it took me a few tries but i finually figured out my problem it had to do with the dhcp lease renewal try staticly assigning your ip address for some god awful reason my adapter wasent getting a new renewal from my gateway hopfully that might work for you

Thanks for that. I do think that dhcp/dhclient or whatever is the problem... I'll keep you posted!

thats because dhclient is in the /sbin directory (needing root permission). do
#su
#/sbin/dhclient wlan0

that should yield better results.

if it still shows as not found (highly unlikely), try looking for it with
#whereis dhclient

Thanks for the reply. here are the results...


Password:
linux:/home/adrian # /sbin/dhclient wlan0
bash: /sbin/dhclient: No such file or directory
linux:/home/adrian # whereis dhclient
dhclient:
linux:/home/adrian #

However... I am posting this using Linux!!!! Yippee it works! I found that I had set my WEP key as a 'passphrase' rather than as HEX. I changed that and here I am.

Still one problem left... Konqueror web browser works, but Firefox doesn't. I'm sure I'll crack it soon though!

I'm having to use Konqueror!!

Konqueror is fine but Firefox is acting VERY odd. It will quickly load up pages from the Novell website, but is very very reluctant to load other pages. The novell pages aren't loading from the cache and they usually load quickly. Some other sites will load occasionally, but I usually get a time-out error. I haven't managed to load the Google homepage more than twice for example!! Meanwhile Konqueror is loading site after site.... How can this be??

Any luck getting Firefix working?

I am asking becuase I have a similar situation. I can connect to my LAN via NFS but I get no Internet access! I have not tried Konquer, but I will tonight. I use the machine to play poker online and wireless is way better than wired for this ... no waiting for breaks!

So I'll try the static IP or /sbin/dhclient as su and see what happens.

i take it your poker sites use java of some sort? I found out that konq's java engine is no where near what firefox's is. Sorry i couldn't get more technical, i just know that things that did work in firefox, didn't in konq.

Also, when i used Firefox or Konq for my yahoo mail account, it would crash, and i know there was a problem with both these browsers, however, i was told it might have been fixed. search the net for these two things java and firefox, and : firefox gmail problems.

I have a small idea.
i am not certainly sure about, because i'm a bit newbie, but on my experience...

My point is about the noise, link quality can be very good, 100/100
Then we have the signal level -40 dBm and then the NOISE LEVEL -256 dBm

I'm going to splain you something wich is called: EMI
Electro Magnetic Interference

And everybody knows what a radiowave is, travelling through the atmosphere's electrons of hidrogene etc... or am i wrong?

and so many different frequencies passing on the same space... may cause interferences.
all depending of the strength of the wave beam, 1 or more all together, also depends of your antenna.
The antenna is the fisical conductor for that traveling invisible wave.
the antenna fisicly, has a structure, and in between one stick and another, there is a measured distance wich will be the same distance as the wave opens wide... or more or less.

THEREAFTER you have a NOISELEVEL of 256.
So yeah! You may have a signal, enough to get an essid name and etc.
But the other Noise surrounding doesn't let you listening properly.
I heard once that if is more than 100 dBm (or should i say less than -100 dBm ?)
won't work
Signal and noise levels... those numbers should be by under 100, with 2 digits, from 00 to 98 or 99. after that is a caos
good luck!
