Hi Welcome to JustAnswer.com I am Tech Specialist and today, I will be trying my best to solve your issue.
Are you using the ipad now?
Is it connected to wireless?
Do you have a computer connected to router?
Why don't you reset the router again?
I guess you did not reset it correctly.
take a pin. insert in the reset hole
press and hold it for 10 seconds
now you should be able to connect to the router
Its not resetting properly
launch safari in ipad
once done, open this address
Let me know what happens
leave the username field blank
and use admin as password
let me know if linksys page opens
Use admin as password and leave username field blank
you are not resetting the linksys correctly
insert a pin into reset hole and press it/hold it for 20 seconds
all leds of router will flash together and it will reset
have you reset router again?
I am out of options
I will open this for other experts. Sorry about that.
