Did you used Setup Network Wizard from Window XP.(Setup home or small office)
I setup my wireless network this morning. It worked great. Similar setup like your. I have my laptop is wireless and desktop is wireless also. After go through Network Wizard setup. I am able to view share files from either computer. My sticky point during wizard setup was the choice of my connection to the internet. There are total of six choices. My setup was number 4. To get to selection number 4. You have to click Other then click Next. After that select the first choice.
Good luck. Please let us know again.
I am attempting to setup 2 wireless networks together but allow them to use their each individual internet connections, they are in close proximity of each other and share the same SSID and WEP password, yet I cannot see/nor access files or systems from one network to another? Does anybody know how to painlessly correct this issue?
