Ethernet Problem after OpenSuse 11.2 instalation

Hello! I do not speak English, so I used the google translator …
My problem is this:
After I install the version 11.2 my computer no longer recognizes ethernet (eth0).
While with the 11.1, everything was right. My configuration of the signal received by wireless Internet and transmitted by ethernet to a router that distributes the signal.
To install 11.2, unformatted machine, just updated the system through the installation DVD. For this reason, all the network configuration was maintained - or at least, seems to have been maintained. My wireless works perfectly, but the ethernet does not …
In Yast, when I go to network settings, the following appears: NetLink BCM5787M Gigabit Ethernet PCI Express (not connected)
I’ve tried everything, but so far nothing …
The activation device is to be done at startup, the area is inside the firewall, it was assigned MTU, the IP is statically assigned, and the name of the module is tg3.
By using the lspci on the command line, I have the following:
02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
Already have with ifconfig:
eth0 Link encap: Ethernet HWaddr 00:1 D: 72:04: C8: B4
UP BROADCAST MTU: 1500 Metric: 1
RX packets: 0 errors: 0 dropped: 0 overruns: 0 frame: 0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisions: 0 txqueuelen: 1000
RX bytes: 0 (0.0 b) TX bytes: 0 (0.0 b)
IRQ: 16
I’m waiting for suggestions …
Thank you very much.

The ifconfig output shows eth0. Isn’t that your ethernet interface?

What is the result of

cat /etc/resolv.conf

/usr/sbin/route -n

Thanks for the help, but I found the problem. It was with the router, not the ethernet.
