I need help solving a mystery.
I have a customer with a laptop and a desktop. They are connected together and to the Internet through a wireless network. Both can surf the Internet perfectly.
The AP/Router is a USR 5461 with the latest firmware; the laptop is a Centrino (with the Intel wireless card); the desktop is Ethernet connected to an external D-Link DWL-3150, 802.11g Wireless G Bridge.
The desktop use to have an internal USR5417 PCI adapter, but I removed it after the USR driver crashed winsock. (USR makes really crappy drivers.) There was no symptom change after switching to the (external) D-Link DWL-3150
The printer to be shared is on the desktop. Both computers are XP-Pro-SP2.
I have both TCP/IP and NetBEUI installed. Both workgroup names are identical)
When I connected the two computers directly together with an Ethernet crossover cable, I can print perfectly over the crossover cable from the laptop to the desktop. And, I can do this with both computers security software running. So far so good.
But, when I re-hook the wireless, neither can see each other, with or without both firewalls and antivirus on or off. They can not see each other in network browse -- they only see themselves. I can not force the issue with "search" and manually placing each other name in the the search field.
In the laptop's printer server properties, I can not manually add a port with the path to the desktop's printer.
Editorial comment: AAAAAAAAAAAAAAHHHHHHHHHHHH!!!!
I am suspecting the USR 5461. But, I really don't want to invest in a replacement (D-Link DIR-655) until I know for sure.
Anyone have any suggestions?
