only partial connectivity to internet after new 11.2 install

After earlier problems with 11.2-32, I replaced the 8 year old MB with a new Asus and an AMD Athlon II dual core CPU, 4 GB of RAM. New HD. First install of openSuse 11.2-64 completed, but have not been able to update repositories and Firefox won’t connect to any WWW server outside of the LAN. Errors are about not being able to download from repos, can’t resolve address, yet from a terminal on the 11.2 machine I can ping download.opensuse.org, yahoo.com, and the DNS servers. But the Updater Applet says “repo not available: failed to download…” It appears some programs, including the Updater Applet, can’t resolve download.opensuse.org while others can.
I’ve gone through the configs of Network Settings in 11.2 to make them match a working 11.1 install on another machine. I’ve looked at the fire wall settings (http is not an option on the pull down list), Checked the router settings, but that shouldn’t be the cause since the machine with 11.1 operates normally from the same LAN.
Another odd thing: Obviously can boot from the CD drive, but putting a data disk in, Dolphin doesn’t show the files. Related?
What am I missing?
Thanks,

Reinstalled. A glitch in the first install?
