|To access the homepage of a router you simply enter the numbers (otherwise known as its ip address) into the browser (where one enters the name or address for any website); then press Enter/Return on the keyboard.|
Ideally you do this with the computer attached to the router via an ethernet cable (often referrd to as a cat-5 cable).
You can use any computer to do this, and whilst you can also use wifi to connect to the homepage, and then view or make changes to the router's settings, generally better (wiser) to use the cat-5 cable approach. Why use the cat-5 method - you may make changes (deliberately or otherwise) which may either disable wifi (albeit temporarily) or in some other way prevent wifi connections from working. Using the cat-5 (ethernet cacle) means you can still connect to the router, pending restoration of wifi (should wifi be not availBle for whatever reason).
You do not need the broadband cable plugged into a router in order to access the router's homepage. But when you wish to actually go online, and/or check the incoming dsl service itself, then you do of course need the dsl cable connected.
Generally there is no reason not to have the dsl cable connected when accessing the router's homepage. Thus I see no reason to ensure it is connected last.
A word of warning... whenever one access a router's home page, be very careful what you do. Make any changes carefully. Ideally note carefully what given settings are prior to making changes.
All routers arriveve with a default password to allow access to its homepage, likewise a user name. Typically these might both be Admin, or admin, or Administrator or admimistrator; or other variations. Frequently there is a label with this information on the base of a router, and often is with a card/sticker in the router's box when delivered.
This user name/password combination can be changed; and if it is... then very wise to make careful note of what you change it to.
If you "reset" a router to factory state (usually by pressing a reset button located on the back, often via wee small hole using a paperclip), it will erase all changes you may have made; and restore all settings to as delivered.
