Had bad experience with this router that I bought from 11street.my from a shenzhen vendor which I just received last week.

1. 5ghz wifi doesn't work since day 1
2. Updated to latest firmware 3.0.0.4.384.32797 doesn't fix 5ghz discovery problem
3. After i changed region from China to Singapore under advance wifi setting, both wifi and ethernet becomes undiscoverable.
4. After flashing latest firmware with ASUS Firmware Restoration version 2.1.0.1 tool under rescue mode, the router auto restart every 10 second.

Totally gave up on this particular router, requesting exchange. Hopefully the Shenzhen vendor responds. Too bad because I read good reviews from tech blogs but bad feedback in forums.
