Using the CLI Template, everything works perfectly with one exception... while connected through the internal wlan, laptop cannot ping/browse with any other device on the wlan.

Communicating with router & router int. work fine, also communicating with wired devices work.

Suggestions/feedback would be greatly appreciated!!

about what your problem is and you should get some help!

What router? What CLI template are you talking about?

by churdoo

This may simply be a security setting within the access point. Many WAP's or Wireless/Routers today have a setting which isolates wireless clients much like you're describing, and oftentimes it's enabled by default factory settings. I don't recall what this is called but you should be able to figure it out, or post back more info including WAP/Router mfr/model, etc.

I'm using a Cisco 871w Router, and am using the CLI template available on TechRepublic, http://downloads.techrepublic.com.com/abstract.aspx?docid=256394

I have tried using differnet Wireless security, but currently using WPA.

See config below:
