Its depends on you and your requirements
Whats you need and also your system capacity. I think you must consult with a network administrator.
Yeh and pay a $200 call out fee
Basically, It really depends on what devices you have in your house, what requirements you need for them etc.
If you have a Wireless Network Media Player with Wireless-N, you should go for a Wireless-N Modem/Router
If you need to have a high bandwidth between computers on the same network you would want to go for a Gigabit router.
Basically, answer these questions:
1. Is this your first router, or are you seeking a replacement, if so why?
2. What devices do you have in your house, Wireless and Hardwired devices
3. Do you have a standalone modem available, or are you seeking a Modem/Router with a built-in Modem?
4. Are you particularly Networking savvy? Are you bothered with the details or do you just want something up-to-date and good for the money?
5. Any additional requirements please detail in your reply
I'm here to help you, and I wont stop at "Contact a Network Administrator" as It kinda defeats the purpose of my existence on this forum if I wasn't here to help.
Anyways feel free to ask me any questions you like.
Thanks
