Ah that's a piece of string question - it depends on: whether it's wrong; in what way it's wrong.
It might be as simple as the network cable has come loose.
Whether the TiVo plugs directly into the router or goes through Powerline (or a wireless connection) makes a difference. (You didn't say)
Maybe the Sky router software has updated and is now blocking TiVo. The router should have a web interface (that you can access from a laptop's browser at your Mum's house - e.g. "http://192.168.1.0" - password is on label on bottom of router!) and will show you "connected devices" - obvs TiVo should be one of them.
If TiVo is visible on the home network then you can connect to it via telnet (if you have it) and then see if you can access the outside world from TiVo (e.g. by typing "ping -c 5 8.8.8.8" into telnet).
(Normally I wouldn't list all these at once but I appreciate you need to have suggestions in advance of going to your Mum's.)
It's hard to say without knowing what TiVo says. There is no simple "do this to fix it" answer to these things, sadly.
Personally, I would go with a loose cable as the probable cause!
