A second router always helps along the way . . .
I used to have cable modem 1.2Mbps line from Adelphia, and now I have Verizon FiOS Lightning Fast Internet connection at about 5.4Mbps. Well, even so, I know it's a big step up from the previous internet connection, although still quite fast. I am writhing this to inform you that if you are only using a single router, like a Linksys, then try another Linksys in the chain. Or, connect a D-link to a Cisco Netgear or something. This is a smart thing to do whenever you have 3 or more computers and 3 or more constant streaming services routing out to different areas of your home.
If you prefer wireless, then maybe you need an airport or something to extend the range of your particular wireless router. Wi-Fi these days have wireless-N, which is faster, but can be very temperamental. If it's reliability and speed you're looking for then use a router that has Wireless B+G mode and Wireless +N mode options both installed.
I have a main modem/router from our ISP. Then it is connected to a Linksys router with B/G Wi-Fi and SAS security. This is another good thing. If you are worried about other people stealing your internet connection access-point, and you are not so good with hash algorithms, then you want a router that has its own two-way encryption feature for automatic and instant setup.
We also use a $99 Airport with B/G/N altogether. It makes a good home entertainment or media device, and works with most DVD players.
You might also want to have someone in the family that's good with routers/hubs configure all the other settings on the device for you, so that you can have multiple options when using the internet and your own applications in harmony.
