Slingbox stopped working with tp2

[rdcrds]

Well with any phone really but my tp2.

I was offered by my cable company a free netgear router (mine was broke)

And also a faster speed internet from 10mb to 20.

As the guy was putting it in i showed him slingbox and how it worked so it was working fine then he put in a new router and a new corde but that was it we never touched anything on slingbox

Well i can't get the slingbox to show up on my router.I have tried everything i can think of.I have rebooted checked all connections but it is like it does not see it there.

He did put a security key but not sure if he did anything else that would stop my new router from seeing it.

Any help? i posted on sling community but you understand that gets you no where anyone have any ideas?
