I bought my first XBOX 360S a couple of days ago. I am trying to connect using my dell inspiron 1525 laptop,Vista, as a WAP. I get my internet through a sierra wireless USB stick. I am on a drilling rig and do not have an ethernet cable to try the wired connection to my laptop.I have been all over the net and tried about all the suggestions I could find. I have full bars for signal but my xbox won't connect to my laptop. I have tried both full automatic settings and manual for the addresses and have 2 networks set up.One with security and the other with out. I have shut off my Kaspersky internet security to see if that was causing the problem but it made no difference. When I open command prompt,ipconfig/all it shows addresses for the sierra stick but the dell wireless card it shows no ip addresses just saying DHCP and autoconfiguration is enabled. Test results from the xboxs are can't connect to your network hardware. Anybody have any Ideas?
