How to make my at&t wireless modem faster? Would a router make it faster?

I have AT&T fast internet service with the 2wire wireless modem. This is my question it seems that it is not running fast. This is what I have in my network rather logged onto it. A desk top PC, Laptop, XBOX, Wii, 2 IPAD Touch and cell phones when surfing. How can I surf faster is it possible is the modem good enough or should I buy a faster router. Is my question possible or makes sense. I am not the best person when coming to computers. Thanks

In regards to your actual internet speed you will mainly need a faster internet connection. You haven't posted your actually speeds so I'll assume you have a cheaper DSL package. DSL can be slow, so I recommend either upgrading your package or going with a different internet provider.

Thanks for some answers. As far as the service I have the fastest DSL service that ATT has. I know that COX cable service is faster but I have ATT. But if I purchase one of the faster routers say Walmart sells would that help in anyway. I recently looked at onE which hooks up to the 2wire I got from ATT. Is that a way to go or which type should I purchase. As so how do I check what my speed is and if its on a good channel. I read some place that a good channel setting as so helps. I think that was the way I read it. Thanks
