Quick router question

[Masterdog]

Hi guys,

I'm thinking about getting this router. Reading a review of it, though, it says this:

Netgear's channel bonding setting appears in the wireless settings as Mode, with a choice of "Up to 54Mb/s", "Up to 145Mb/s" or "Up to 300Mb/s". This is deceptive, as most novice users will logically choose the highest speed rather than the unbonded 145Mb/s option.

I'm a bit confused as to why it's bad to choose the 300mb/s option? The article I read it in suggests it may cause problems with other networks but assuming I don't have one, I don't see what's wrong with the full power. I'm mostly clueless when it comes to networking though so maybe someone can explain.

Thanks,

MD
