Can only ping the router, but not the internet with WLAN?

Hi,

I just loaded SuSE 9.3 on my laptop. When I connect the laptop directly
through the NIC card to the Netgear router, the interface works fine and I
can surf the net.

Next I tried using the Belkin FD6050 to go wireless. The YaST configured it
fine, and I am very impressed with the setup that took seconds to recognize
the card and allow me to set up the WEP, etc. But now the trouble starts.

While I can ping my router (192.168.0.1) and browse the router setup page,
it is not able to connect to the internet (ping www.yahoo.com returns
"unknown host"). I tried turning off the firewall, but it did not change
that behavior.

(Note that the router serves other computers, both direct and through
wireless, and they all can access internet - the effect is localized to the
Linux laptop)

Any hints on why this may be happening?


Thanks
SB

Try editing the /etc/resolv.conf file and add the DNS info as supplied
from the router's admin configuration page;

nameserver XXX.XXX.XXX.XXX
nameserver XXX.XXX.XXX.XXX

and/or add the router as the namesever to this file;

nameserver 192.168.0.1

Also check at Netgear's web site for a possible firmware upgrade.

Sounds like your DNS is not attaching to your wireless card. If the card
is functioning correctly you should be able to ping a server by ip
address. Try 24.116.0.201, it is a dns server. If it answers you indeed
do have a dns problem with your wireless card.

Make sure you do a check to update 9.3. This helped solve my wireless
connection system problems automatically although they were not th esame as
ypurs.

run:

Is there a default one?

Just to be sure, I connected to the AutoUpdate and caught up with the
upgrades. It now works (not sure if upgrade helped), but the "wlan0"
interface vanishes myteriously (I have posted it as separate ques on the
usenet).

Also, as per sugegstion from one of the post, I have "saved" the YaST
configuration, and I reapply the config whenever I see that the
configuration is misbehaving - it helps a lot. The file /etc/resolv.conf is
automatically changed depending on whether the kernel could connect to the
DHCP or not - and this is disconcerting, since the kernel may be using the
wrong interface to ping the DHCP server. Saving and retrieving the YaST
config can take care of this pesky problem.

check also the contents of /etc/resolv.conf
should have a nameserver line with a ip-address you can ping.

Somewhere on this newsgroup, not sure how long ago....is a message from
myself that described the exact steps I went through to fix the same or
similar problem. Essentially, you need to use YaST to indicate that the
eth0 port be dependent on whether the network is plugged in there. It is
somewhere in the Network Device setup.

Search this newsgroup on Google to find my message indicating the steps I
took. Someone else on this group pointed me in the right direction...

Whoops didn't note the crossposting. Search the alt.os.linux.suse
