Reinstalled OS, no wireless

[CPH]

I had a new HD installed and Windows XP Home Edition reinstalled on my desktop. I can't get the wireless network that connects the desktop to my laptop to work again.

I can't ping (by IP address or name) the laptop from the desktop, or the desktop from the laptop. Computers are in the same workgroup etc. Node=none.

I shut down the MS firewall and turned off WEP. No effect.

After the reinstall, my desktop IP address changed from 192.168.1.33 to ..1.34, so I made appropriate changes, including changing the "IP Pool Starting Address" (from .33 to .34) in the router.

Network Connections in desktop Control Panel shows a 1394 Connector and a Local Area Connector. The LAC has-
Client for MS Networks
File and Printer Sharing
QoS Packet Scheduler
TCP/IP

The TCP/IP Properties include: Obtain IP address automatically, Obtain DNS server address automatically, (in Advanced) IP DHCP Enabled, and Default for NetBios Setting (I changed that to Enable NetBios over TCP/IP without effect).

The 1394 connector has the same settings for TCP/IP properties.

So, I'm stumped. I've rebooted router and computers.

By the way, the laptop connects to the internet with no problem.

Thanks for your help.
