Address revervation issue has been solved by the beta firmware, but you have to login its web interface to do that,
What's the IP address obtained on your PC connected to C9? Is it correct?

Managed to sort it out.Seems to be a problem with Google Chrome browser.You could login with Internet Explorer. Now updated to the beta firmware and it seems to be working.Now have the access control and dhcp reservation working together.Thanks

What version of Chrome are you using? I have no troubles on 45.0.2454.93.

This may be related -- since I upgraded the firmware from the out-of-the-box to the latest Beta, I go to 192.168.0.1 in Chrome 45.0.2454.93 (64-bit) on OS X 10.8.5, and I get forwarded to port 9080 but get a "No data received -- ERR_EMPTY_RESPONSE message. However, if I go to tplinkwifi.net I do get forwarded to http://tplinkwifi.net/webpages/login.html and all works ok.

I am still having this issue even after upgrading to firmware version V1_161008, then downgrading to V1_150514_US. I have tried on latest IE and Chrome and the only thing that allows me to login is entering http://tplinkwifi.net and changing LAN address back to original 192.168.0.1. If I change it to anything else, it has redirect 501 errors, and clicking the Home button fails.
