Internet Cable

Hubby brought my laptop with him because it is smaller than his. He also brought with it the wireless card so that leaves me with the CAT5e internet cable that I use with his laptop. My problem now is it is not long enough for me to extend it to the bedroom. I can't do much work online once my little one is asleep since she is sleeping in our bed and I don't want to leave her alone. It's either I will get a new internet cable or practice her to sleep in her crib, I will see what will come first.
