Wireless (probably DNS) problem with openSUSE 11.2

English Network/Internet

Hello,

I have a problem with my wireless connection under openSUSE 11.2 (x86_64)

I have the following wireless card:
03:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

lspci -n gives:
03:00.0 0280: 8086:4230 (rev 61)

connecting works fine: iwconfig gives:
wlan0 IEEE 802.11abgn ESSID:“playa-sol-palmera”
Mode:Managed Frequency:2.462 GHz Access Point: 00:1E:2A:D9:95:47
Bit Rate=54 Mb/s Tx-Power=15 dBm

Power Management:off
Link Quality=70/70 Signal level=-30 dBm Noise level=-94 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

I also obtain an IP address:
ifconfig wlan0 yields:
wlan0 Link encap:Ethernet HWaddr 00:1D:E0:4E:98:47
inet addr:84.75.105.203 Bcast:84.75.111.255 Mask:255.255.240.0

TX packets:40 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:4382984 (4.1 Mb) TX bytes:9321 (9.1 Kb)

However, I cannot resolve any DNS names. What could be wrong?
Thanks, any help is appreciated.

The IP number of the DNS server in file /etc/resolv.conf is wrong. Please check and edit it manually. And update your NetworkManager package.

If modifying /etc/resolv.conf does not help, then post the output of

/sbin/route -n

Thanks for your answers, modifying resolv.conf did not help.
So here is the output of /sbin/route -n

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
84.75.96.0 0.0.0.0 255.255.240.0 U 2 0 0 wlan0

I am not sure how to interpret it. My wired connection works and here is the output (if it helps):

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
84.75.96.0 0.0.0.0 255.255.240.0 U 1 0 0 eth0
0.0.0.0 84.75.96.1 0.0.0.0 UG 0 0 0 eth0

Thanks a lot!

Do you see the difference? Your wireless connection does not have a
default gateway (the one with the UG flags.). Because of this, the
device has no route to the outside world. This is a known bug. Using
your wired connection, do an update. Then using the NetworkManager
applet, delete your wireless connection and remake it.
