Wired Networking Works, Wireless Doesn’t

File/Print sharing works perfectly between my wired XP desktop and wired XP laptop. However, when I switch the laptop to wireless connectivity (via Linksys Wireless Access Point), File/Print sharing does not work (Network path not found). In fact, I cannot see the other networked computers in wireless mode. Windows Firewall is off on both machines, and I have configured Norton Firewall (desktop) and ZoneAlarm (laptop) for LAN access. The laptop wireless adapter has “File & Printer Sharing for M/S Networks” enabled. I’m stumped. Any ideas?
