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.
