Asus RT-N66U Dark Knight Gigabit Router Wireless - N900 setup

[#1]

Hi,
I have recently had Plusnet Fibre Broadband installed and whilst far faster than my old broadband am having range issues at the outer edges of my house. I have therefore purchased the above router to swap for the Technicolor router to hopefully improve connectivity in the weak areas. However, having never done this sort of thing before I am struggling to connect to it. Pretty sure I have it all plugged in correctly as my devices can see it OK but I'm being asked for user names and passwords (??????@plusdsl.net and my 'normal account password') none of which it will accept. I have searched the internet and what I've found is gobbledygook! Can anyone provide me with easy to follow steps to help me set it up for Wi-fi connection?
Thanks in advance.

If you are putting in the right username and password it should work. I have this router and it's a beast

Hi Ian,
Thanks for your reply. It's a router only - I have a BT modem which was supplied at the time of the fibre install so the BB's coming through that.

Hi Thomas,
Thanks for your reply. I have checked and double checked this and am pretty sure I've got the right info. I'll try a call to Plusnet today from work or tonight to triple check and maybe try a different PC.

Do you have your router's WAN port (to the modem) configured as "PPPoE" ?

It might be worth double checking the exact format of your PPPoE Username, by checking your "Login name" in the Connection Settings section in the Plusnet 'Member Centre',  as some customers usernames (including mine) ARE NOT in the format "account-name @plusdsl.net"
