Any Idea?? Thanx Problem: -I try two set up a ad hoc between two computers under XP. -The wireless cards seem to work (green light and card configuration utility OK). -In the "Network connection panel" the wireless connection icon is NOT visible and the connection is seen as a "local network or high speed connection". -The "Wireless Zero Configuration Service" is running. -The two computers do not see each other in the windows network panel. No ping is possible. They do if they are connected through a classical patch cable. Config: -ad hoc "network" between one laptop (XP Home) and one workstation (XP Pro). -2x 11Mbps Wireless PC Card (Wisecom WS-WP100) -1x PCI adapter (Wisecom WS-WK100) Driver: -File: cw10.sys -Version: 0.29.10.2a

You're trying to hook them up directly? If so, sounds like your "classical patch cable" is a standard Cat5 cable. You have to use a crossover cable.... Might be easier just to get a hub.....

1. Make sure that XP's firewall is off. This is the most critical. 2. Make sure the ip addresses of each computer are in the same range. 3. After doing both 1 and 2 make sure that each computer contains a MATCHING account (both username and password) of the one used to logon to the other. Or enable the guest account on each machine (something I would not recommend).

Thanks for answers: 1. About Lucid answer, I am not sure it is relevant, because I just mentionned the cross over cable to explain classical wired networking is set up and account setting is OK. I do not intend to keep working with a cable between the computers, it is just a validating step on the way to wireless. However thank you for your hint. 2. About Paul H answer, ICF/ICS is OFF, IP adresses are 100.100.100.104 and 100.100.100.105 with submask 255.255.255.0, and user accounts are the same on both computers. I also thank you for your answer. My impression is that the issue comes from the fact that I do not get the "wireless network connection tab" even if WZC is ON... Something is not detected from XP, and I am looking for knowledge in this very narrow area... The best would be to get a "testimony" from someone using the same Wisecome wireless adapters... So I can compare XP configuration. Help... (;-))...
