SUSE 11.4 Realtek 8187B WEP WiFi - no access to Internet

English Network/Internet
#1

Hey there, my first post here, just installed SUSE 11.4
I did read the stickies and some other posts, so here’s the output of my problem:

In short - my adapter is working, authenticated on the selected AP, I can ping the AP, but I have no access to the outside world.

Here’s the commandline output:

What might be wrong and where should I look for help?
btw forgot to mention, using same AP and password under Windows grants me internet access

#2

Are there name servers listed in /etc/resolv.conf ?
Can you ping those servers?

If you set your connection up manually you’ll also have to define those. If you’re using dhcp you should obviously get them automatically.

Can you ping external websites like google.com or yahoo.com?

#3

contents of /etc/resolv.conf are:

search FOREST local.lan
nameserver 80.58.61.250
nameserver 80.58.61.254

cannot ping external IPs or hostnames, can only ping the AP
btw I am using KDE and NetworkManager is off, using YaST

I assume those are valid. The nslookup name for the first is
250.Red-80-58-61.staticIP.rima-tde.net, so if your ISP is rima-tde.net, then
they are probably OK. In addition, a bad resolv.conf would not prevent your
being able to ping a valid IP. I think you have a routing problem. If you look
at the output of the ‘/sbin/route -n’ command, you should see at least


Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 wlan0
192.168.1.0     0.0.0.0         255.255.255.0   U     2      0        0 wlan0

My prediction is that you have the second line, but not the first. The second
line knows how to route things to the 192.168.1.X network, but not to any
external network.

To add the additional line to the routing tables, use


sudo /sbin/route add default gw 192.168.1.1

This will provide the default routing to get to the rest of the world. Doing
this once might not be permanent. If not, add the part beginning with
/sbin/route to /etc/init.d/after.local.

Thanks a lot! That was really the problem and your solution worked perfect!

Glad to hear. You made the diagnosis easy by presenting exactly the info that
was needed.

You guys Rock…I am setting up a new machine on 11.4 and my /etc/resolv.conf was all commented out with only one line in it that said “search site”
I changed to nameserver 192.168.1.1 and all is working.
Is this file dynamically changed by network manager?
Thanks,
Pete

Yes, as long as it has not been modified by you; however, it sometimes gets
confused. If you have the file /etc/resolv.conf.netconfig, then resolv.conf was
not updated because it was thought that yours could not be overwritten.

If you ‘sudo cp /etc/resolv.conf.netconfig /etc/resolv.conf’, then it should be OK.
