Hi -

Quick suggestions:
1. If possible, focus on your wired connection first (worry about Wifi afterwards)

2. Run /sbin/ifconfig
Verify that it sees your NIC (or both NICs)
Verify that they're active, have a valid IP address, and a valid subnet mask

Code:

EXAMPLE:

/sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:76:E2:71:C5
          inet addr:192.168.1.209  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:76ff:fee2:71c5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:2044864 errors:0 dropped:0 overruns:0 frame:0
          TX packets:716204 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:520330689 (496.2 Mb)  TX bytes:743375788 (708.9 Mb)
          Interrupt:10 Base address:0x2f00

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:56777 errors:0 dropped:0 overruns:0 frame:0
          TX packets:56777 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:164245436 (156.6 Mb)  TX bytes:164245436 (156.6 Mb)

3. Run "/sbin/route -n". Verify that your gateway is defined. Verify you can "ping" it.

Code:

EXAMPLE:

/sbin/route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         192.168.1.1     0.0.0.0         UG    0      0        0 eth0

ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=6.90 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=1.37 ms
...

4. Verify your DNS server. Verify that you can "ping" it.

Code:

EXAMPLE:

cat /etc/resolv.conf
nameserver 192.168.1.2
...

ping 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.
64 bytes from 192.168.1.2: icmp_seq=1 ttl=128 time=1.13 ms
64 bytes from 192.168.1.2: icmp_seq=2 ttl=128 time=0.213 ms
...

'Hope that helps .. PSM

Make sure your dns settings are ok.

Type dig at cli and see what it says about the dns servers.

In debian there is a list (2 or 3) items relating to the servers.. in a file called: resolv.conf Suse should have something similar.

Lettuce know.
