Gosh, so I have been asked to post my password details off the router and now I'm being told it isn't safe? Thank you for removing. But why was I asked to put them in the first place?
There are three usernames and passwords involved.
1) The router setup access, which is what we are trying to help you find, so that you can obtain the line statistics. Without those nobody can tell you whether or how your connection can be improved. With them it is easy and you may get a few different suggestions. The common ones have been suggested but some ISPs change them to unique ones before sending the router to you.
It looks as though you've found those

.
2) The Wireless connection username (SSID) and password, if it has wireless connection to it available for your equipment. We don't need that
3) Your ISP broadband username and login password which you should never post, and that is what has been deleted. With those a malicious person, (and posts on these forums are visible through google), someone could try to hack into your account. Just like your phone number or address - not here or anywhere on the net.
I hope that helps
