okay well im not sure if this is the right place to put this so i apologize if it isnt before hand.

i have a linksys WRT110 and it has worked perfectly fine for me up until today when the number '1' on it just simply turned off and essentially took my connection on my Ipad with it. when i turn on my computer the number lights up and my connection is suddenly on.
i dont understand why it can work so well for so long and suddenly decide to change and i would like to change it back so i can continue to manage the things i need to while watching my children.

i have no clue whats wrong with it or how to fix it.
i get my internet threw comcast if that matters.

i would appreciate all and any help.
