if you have not changed the default password and user name !
it is listed on the web page on the above link

Go to wireless tab at top of screen and look up WPA Key or WEP key and make a note of what it is on 2.4 GHz frequencies as I think this will be dual band with 5 GHz as well but Ipad will run on 2.4 GHz only as it will be 802.11n as opposed to 802.11AC

Note if you changed the user name password or user name you will have to reset the router back to factory defaults but be aware everything defaults so ISP cable settings reset (would need ISP to tell you what they are and help set them back up)
(wireless settings change so you need ethernet cable directly into router to set up wireless)
Hopefully your still set up on the router on the default user name and password !
