"Top of the line router" only for a Intel Ultimate-N 6300?

http://forum.notebookreview.com/asus/507261-asus-g73jw-gentech-1645-a-49.html#post6740064

Do I honestly need a "top of the line router" in order to make the best use of an Intel Ultimate-N 6300 in my ASUS G73JW? Also, if I'm the only person in the house using wifi, or my internet connection for that matter, do I even need a router? I use my modem from Qwest for wifi and it seems to do just fine. I suppose I could use a router if I wanted to use my laptop downstairs, further away from the modem (include some walls here and there), right? Or should my modem be more than sufficient in order to provide the best connection the Intel Ultimate-N 6300 can use?

Sorry, I'm a bit new to the wifi field and have rarely used it.

Thank you for your help!

 

The post you linked to is kind of true- with a strong accent on “kind of”.

There are currently only TWO routers that support 450mbps and both are in fact slower than the best router that supports 300mbps.
Second and most important aspect is that if you are the only person to use Wi-Fi you won't benefit from such an upgrade at all in most cases.
802.11n improves throughput on LAN but you have no LAN if you're the only user.
So if your internet connection (provided by the ISP) is slower than some 20mbps you don't even need 802.11n to take full advantage of it (802.11g would be enough).
If your connection is faster than 20mbps even the slowest 802.11n that is 150mbps would do.
To sum it up- if you're fine with your current gateway don't be bothered by that. Those routers (300mbps and 450mbps ones) are meant for people who transfer files on the LAN between computers- something you don't even do.

 

One benefit would be available 5Ghz band, if the regular 2.4Ghz is crowded with other wlans already.
