I recently installed openSuSE 12.1 from a distro disk and am unable to connect to the internet. I installed it, dual boot with Windows Vista, onto a HP Pavillion dv7-1245dx Entertainment Notebook PC. I have tried to connect to several public wireless networks, both encrypted and non-encrypted, to no avail. I will list some outputs below. I am sitting in a library with a separate Windows computer typing this thread now.

1. Can ping the loopback address on the SuSE laptop just fine.
2. Can ping nothing else, nslookup www.yahoo.com just sits there.
3. Cannot ping the SuSE laptop from my Windows computer.
4. On the SuSE laptop, Can go under Network Settings in YaST and my wireless adapter is recognized with the following details

AR5001 Wireless Network Adapter
MAC: (address is listed)
BusID : 0000:09:00.0
Device Name: wlan0
Started automatically at boot
IP address assigned using DHCP

5. Scrolling through network settings in YaST

Operating Mode: Managed
Network Name (ESSID) LU Big Red
Authentication Mode: No encryption
I click Next, OK, then it goes into Saving Network Configruation, and scrolls from "Write drivers", but it seems to stay a long time on "Activate network services"? It does scroll through to the end though.

I tried dmesg | grep wlan0 but the output is too long to list here.

ifconfig -a

netstat -r

Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
10.81.0.0 * 255.255.224.0 U 0 0 0 wlan0

Thanks in advance for the assistance.

Problem SOLVED. I am now able to get on the internet! Basically, I did not have the correct Gateway IP address in the kernel routing table, so I had to enter it through YaST.

This Linux questions thread helped me figure it out:

http://www.linuxquestions.org/questi...ateway-323479/

From the netstat output above, I noticed that my kernel routing table looked fishy. My Gateway IP address is 10.81.0.1, which is not listed in the table. I went under YaST, Network Settings --> Routing -->, and put the following under "Default IPv4 Gatweay"

Destination: 0.0.0.0
Gateway: 10.81.0.1
Genmask: 255.255.224.0

Does anyone know the correct netstat command for adding the Gateway IP? I now have to go into YaST each time I boot. The aforementioned LQ thread talks about editing startup sripts to make this happen, I will look at that later. This forum is a tremendous resource!

Well done fixing it yourself. Still odd though as your DHCP client should ask for it and the DHCP server should give it. Maybe check your DHCP client configuration and lease file?
