My router can churn out 135mbps over ethernet, and can broadcast 802.11N over 2.4GHz or 5GHz.

My 150mbps USB adapter can only download at 20mbps max. Is it worth upgrading to a 300mbps or 450 mbps adapter? Because of the practicality, my main PC to be wirelessly connected, and I feel I can utilize the bandwidth better.

I don't think adding more bandwith speed capable Wireless adapter will help your original connection speed. Think if my speed is 56mb/s and I plug in 150mbps it wont magicaly increase my line connection to 150mb/s it all depends on your connection namely the isp

Also note that the 300/450 mbps speeds is on the 5 ghz frequency which doesn't penetrate through walls very well....

I assume the OP is talking about downloading from the internet (since file transfers should be faster than 20 mbps over wifi) which then he probably has a 20/25 mbps connection from his isp. having a faster router wouldn't increase the download speed.

I know this, my line speed is supposed to be 120, although I've managed 135 over ethernet. In the super hub configuration I'm using 2.4GHz frequency at "Up to 144Mbps (best for wireless range)". I'm no expert by any stretch of the imagination, but is it not logical to think that a 300/450mbps adapter would be able to extract more from a 120mb connection than just a measly 20 I'm currently getting.

A bit of extra info, my Toshiba laptop has a 450mbps adapter inside, and from the same location as the PC subject to this post, it achieved a 50Mbps connection.
