I've been struggling to get my wireless working for awhile now. I'm brand new to linux. I dual boot win xp and suse 10.2 on a Dell Inspiron 6400 with an Intel 3945abg wireless card.

I've managed to get the wireless to connect to my router but I cannot connect to the internet. Pinging google.com for example returns "Network unreachable".
With the lan cable plugged in, everything works fine.

Please help, I'd like to get away from windows but this is driving me nuts.

hmm. do you use dhcp?

Yes I do use DHCP.

From your wireless connection, can you access the router? In other words, if the router has a web-based interface, can you use your browser to access it?

If it doesn't, can you enter a console shell, type 'su', enter your root password, and then run 'ifconfig'? It will display all of your network devices, and whether they have an IP address assigned to them. Check if the wireless device has an IP address assigned to it.

Are you using wireless encryption?
If you can ping 64.233.167.147 vs www.google.com then you have a DNS issue where /etc/resolv.conf is not being updated.
Is the output of the route command showing your router as the gateway?

Load up your browser, and try to go to http: / /19 2 .168 .0 . 1 and http :/ /1 92 .16 8.1 .1. Those are prolly the addy's for your router/ap and gateway device. (spaces are just used to prevent linking)

you may just need to renew your ip depending on your dhcp settings....

I can connect to the web-based interface. Also, the wireless device does have an IP address assigned to it.

I am not currently using encryption, I just wanted to get it working first. I can't ping either 64.233.167.147 or www.google.com. The output of route is:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.123.0 * 255.255.255.0 U 0 0 0 eth1
link-local * 255.255.0.0 U 0 0 0 eth1
loopback * 255.0.0.0 U 0 0 0 lo


So it appears its not recognizing the router as a gateway maybe? How would I fix that?

That isn't the address for my router, mine is 192.168.123.254, but what is the second address for?
I've tried renewing my ip...no luck.

Thanks for your replies.
Any new ideas anyone?

Try
route add default gw 192.168.123.254

I tried that and it shows up correctly if i type route again, but the internet still does not connect. If I do /etc/init.d/network restart the new addition disappears again in the output from route.

When you added the default gateway did you try pinging by IP address?

For some reason all items which are returned by route are gone except for the loopback one. I can't connect with the lan cable plugged in anymore either. I've tried reconfiguring the network cards but that hasn't helped. I'm very confused.

I've given up on it and gone back to trying to fix my windows problems...thanks for your help though.
