Please note that yes the option is available for that wifi adapter, please take a look at the following links I think it will help you:
What is channel bonding?
How do I improve my 802.11n wireless performance?
Why am I not able to connect at 300Mbps with my 802.11n device?
I hope this help you.
I think you misunderstood the question above... wenderson wants to make his laptop to work at 5Ghz frequency band to avoid interference issues, commonly seen at 2.4GHz band. Channel bonding is not going to work in the way you're saying, because data will keep traveling at the 2.4Ghz band. Check on the 3rd link you've provided, it says: "Although it's possible to implement channel bonding in 2.4GHz it will not be as effective as 5GHz."
Funny because I always thought, as wenderson did, that any 802.11n adapter would work flawlessly with 5GHZ routers... maybe it was not clear for me either...
