Connected to the network, but no internet...

Crunchandmunch47 · 08-07-2008, 01:26 AM

Hello,
I recently installed Slackware 12.1 on my notebook computer (my first time trying Linux). For the most part it works perfectly, but accessing my wireless internet connection has given me a great deal of trouble. I am using an Atheros 802.11abg wireless card, and have installed madwifi for it using Alien Bob's guide. My network is WPA protected and I have setup wpa_supplicant.conf and rc.inet1.conf. No problems. I am able to connect to my wireless network using KWifiManager and interface ath0, but I cannot access the internet.

One thing that I found suspicious is that, upon entering the command "route", there is no default destination in the routing table...I tried using the command "route add default gw 10.0.0.1" and recieved the error message

Code:

SIOCADDRT: No such process

Could this be relevant?

If you have any ideas, or need me to provide more information, please let me know. Thanks!

Please post as well the outputs of "ifconfig" and "iwconfig".

Did you try "dhclient ath0" after wpa_supplicant reports successful connection?

here is ifconfig:

...and here is iwconfig:

As for "dhclient ath0", I had not tried that...here is the result I got

Unfortunately, for the most part I don't know what this means...

Well, I have no clue about the dhcp-stuff, but I know that you cannot...

route add default gw 10.0.0.1

...if your network is set for a 192.*...

eth0 Link encap:Ethernet HWaddr yy:yy:yy:yy:yy:yy
inet addr: 192.168.1.7 Bcast:192.168.1.255 Mask:255.255.255.0

...address. That would mean that your PC does not belong to your internal network, or something like this?
And about the wireless card, isn't it possible that you messed around with the configuration?
Try to have a look at this and this.

Are you sure you have a running DHCP server in wireless network? Getting this doubt as there are no lease offers. This means that no server is listening to your wireless card for dhcp lease requests. This could mean that either you do not have dchp server in your network entirely or it is not at least in wireless network.
You can give it a try by configuring the IP address manually for the wireless card.
