Hi ASUS team

Recently I bought RT-N14UHP from my friend to replace my Maxis Home Fibre router. I did everything as instructed in the router set-up and config guide. I already reset the router. And I had logon to ASUS Router via 192.168.1.1 and key in my ISP account username and password.

After I have selected "Special Requirement from ISP" and click Next, there is a 5 seconds loading and sudden window prompt "asus-router says "connection timed out", I wonder what's the problem as previously I dont have any issue with my Maxis Fibre internet connection

Hope you can help me.
