What to do with a router

Switching to a new broadband provider. I'll be getting a new router. That leaves me with the old one. Its a Thompson technicolor TG582n. Identical the the new one that's on it's way. It's not worth a penny.

My question is, does anyone out there have any suggestions on how I can use this piece of redundant kit when I'm out caravaning. I use a laptop, and I use an android tablet for mobile data. Any thoughts good people?  :-)
