It wouldn't be your wifi- unless you've asked it to.
There are 'parental control' type software programs that run on networks (ie your home network) but you would know if you had this, right?
I think your next step is to contact your ISP (the people who provide your internet).
You'll need someone in technical support. They might ask you to check things on your computer, so call them when you have time and are at the computer.
They should walk you through it step by step, so don't worry.
To me it sounds very much like a routing issue- the info you request on your screen at home (by typing in a web address) goes to your ISP, who then send that request out into the net. Now imagine a 'blockage' somewhere, like a server that's not 'routing' that info onwards correctly so it never reaches the server that has the donor sibling registry on it. Your computer will wait for a certain amount of time then tell you that the server timed out- meaning 'i've waited long enough- nothing's coming back'
Only your ISP can sort this out for you.
So call them!
And good luck.
