Re: Router speeds...

You shouldn't notice a difference.

My guess is that you may be experiencing spectrum collision from  
other 2.4GHz devices such as phones, microwaves, or APs which belong  
to your neighbors (assuming you live in a densely-populated area).   
You might want to try changing the channels in use by your wireless  
gear around to see if it makes any difference.
