I need a new wireless router for my apartment. One of my roommates and I both have the Linksys USB Adapter with Speedbooster. My other roommates is going to be wired. I was going to go with the corresponding Linksys router with Speedbooster but found out there's tons of different versions, seen here under WRT54GS. I have no idea what the pros and cons are to each of those different versions. Please help me decide which version to get or possibly recommend a better router altogether. Thanks in advance!
