after you try to connect and fail.

but first,unplug the wireless router from the power outlet, wait for about a minute, lug it back in and then wait for lights on it to settle down and then attempt to connect

and by the way...its not a router problem...i tried connecting to many different routers and networks i was registered on and its not connecting to any...while other machines can connect normally!!

any idea??? its not working at all!! still the service is stopped and not working and cant be started

[Yankee]

Well if you have the eth0 wired connection disconnected,
the wlan0 wireless connection on (verified), the modem
key correctly entered into network configuration, all other
settings on auto, WEP chosen instead of WPA for security,
it should work.   Unless you changed it to WPA before, which
requires going into the modem itself and changing it's con-
figuration.

Can't be convinced it's a hardware problem yet. 

[muungwana]

how many network interfaces do you have on your computer?

those logs says interface eth0 is online but the firewall drops all incoming traffic.

why would eth0 generate online traffic while you are trying to connect wirelessly?

a bit more info on your setup will be useful.

what do these commands give you?

ifconfig

iwconfig

[drhadidy]

ok,,,,Im sorry i may have tried to connect wirelessly while the cable was in...as its my only way to connect...
i tried again now and this is the outcome

any thing else u need to know??

[muungwana]

re-reading the thread from the beginning and this is the summary:

wlan0 interface is up and it can scan available wireless networks.

The network connectivity test is the one that is failing.If i understand PCC correctly, that means it can associate with the wireless network but its pings to the router are getting ignored.

can you turn off the firewall and try to connect, its dropping traffic on eth0 as seen in your logs could be the reason for connectivity test failure.

[drhadidy]

i tried turning off the firewall... still didnt work!!((
and it used to connect to Wi-Fi networks before with no problem with the firewall on!!
i dont get why i cant start the wlan service manually even!!
guys plz any ideas here???this is killing me really((
