@JD
yes, I have checked /etc/resolv.conf and it contains 192.168.1.1 which is what
is in windows it matches.
@Bill
Yes I see two to three bars and it(networkmanager) tells me that I am connected,
yet I cannot surf the net or add updates. I got it working once, but now I
can't anymore :(,
I read up on
http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch13_:_Linux_Wireless_Networking
and I tried iwconfig as root:
[olivares at quadcore ~]$ su -

This line worries me:

also found above
I checked wpa_supplicant and I ran
# service wpa_supplicant start
# chkconfig wpa_supplicant on
and like I have posted NM puts up two/three bars that I am connected, but I
can't browse or surf.
Thanks for any tips/advice in this thread.
I did not respond to the previous messages because I reinstalled Fedora 14 on
this machine to see if I could connect like I did the first time, but now I
can't :(
Will check up above error with google 'null' .
Regards,
Antonio
