My windows XP laptop cannot connect to my Suse Linux Mail server and Sco Open Server Unix server via the Wireless network. Each time when I boot the laptop I have to ping the windows client machine from Linux and Unix server to enable communication via the Trendnet wireless access point.
What are your name resolution implementations and are all of the devices and software able to use those common name resolution solutions? It may be that you need an additional name resolution implementation.

Does this help?
Can we get more information?
