Can I use a Linksys router?

[Allyzabethe]

Can I (or should I) switch from an ancient Westell wireless modem with a broken antenna to a Linksys WRT54G router? I was given one, but don't know if I can use it or not. I've had the Westell modem since 2004. 

I have a Macbook if that makes a difference. 

The speeds at certain times of the day are horrible, but I don't know if a new router will matter or not. I'd certainly hope that it would help with being able to take the laptop outside and stay on my secured network. 

Thanks in advance,

Allyzabethe

I am not sure, but I think I know the correct answer.

I use the same router in my home network so it should work fine.
