Rule number 1: this is primarily a news site.
Rule number 2: you can use “contact us” above, and your question may publish as “Ask MacGrass”

Even as a technical support site, you provided insufficient detail for me at least to diagnose your problem. (Mac OS X? Windows? Any error message? have you set your APE to connect to netvigator and you MB obtain IP from the APE by DHCP?)

I hope the following resources can solve your problem, doc.
