Yes, that can be the only reason as long as you spelt your username/pwd correctly.
To check username: Have you received any emails from EE? Take your recipient email addy from the email, drop the words in front of "@", add "@fs"; that's your username. It & the pwd are also on the plastic card that you should have got with your Brightbox.
How long since you were 1st connected to EE?
EDIT: It might be worth checking other router settings, just in case:
Broadband Type: ADSL
Encapsulation VC MUX
Internet IP Address Dynamic
DNS IP Address Obtain from ISP
Connection Type Always Connected
Idle Time 0(minutes)
Authentication Protocol CHAP
MTU (576~1500) 1500
