Password

Hi all,

Just had a new VM package with a new router.  Computer has found the Wi-Fi with no issues (just pressed button on back of router and it joined), but I am unable to get my Kobo E-Book Reader to access the new internet.  It's asking for a Password which I do not have.  Old router had a password on the router itself, but I can't find this on the new one.

Help would be appreciated as I need the access to download any new books.  

Thanks in advance.
