Win 7 WLAN, but no internet connection

[masama]

I am using Asus WL520GU with Teddy Bear Tomato Firmware. My main rig using Win 7 Ultimate 64bit is wired to this router. Two other PC using XP are wirelessly connected to this router without problem. I have disabled security on my router, but set up Mac restriction to ensure only authorized wireless devices can have access.

The problem is that I have another Win 7 ultimate 64 bit on my HTPC connected to this router through Airlink 101 USB Wireless adapter. The HTPC can see all my other PC's (1 Win 7 and two XP) and the homegroup without problem, but no internet connection whatsoever. I can share libraries with the other PC's. I searched around and it seems that IPV6 could be the issue.

I freshly reinstalled the system last night, still no luck. Only WLAN and homegroup, no internet. I am wondering anybody has any idea what could be the cause? Win 7, or my router setting.

IPv6 is not really ready for internet use. It is necessary for homegroup, but you will want to have IPv4 enabled.

Look in your router settings and switch to IPv4, and also on your computer.

Thanks so much. I will give it try when I get back home today.
