why only SOME notebooks can connect to my phone WIFI router

[mxl180]

I'm using WM WIFI ROUTER.

I have three notebooks. All have B/G wireless. All can see my phone and connect, but only the ASUS netbook can browse the web with it.

Although it's connected it says "Access : local only" if I hover over the Wireless tray icon.

BTW. Connecting directly via USB is fine.

UPDATE: IT WORKS NOW. Must install HTCWIFI from the link below. The original HTCWIFI doesn't not work for me.
