you can get wireless to do 108mbit but you have to understand how the signal travels and what affects it.

since the signal is in the air it is suseptable to other signals in the air ( and believe me there is a lot in the air going right through your body as you read this ) sometimes those signals run into the same "space " as your wireless signal. Things such as 2.4GHz phones and security cameras etc runin the same range as your network so as you can imagine they have to compete for that space. Your router/adapter have to distingish between the signal it understands and the useless ones and thats when you get slow or no signal at all.

Bottom line is remove everything that shares the same freq. range and you'll be fine. If you live in an old house with concrete walls or metal walls then you're out of luck either way unless you get a directional antenna but then you can't roam around as much cause you're confined to a small area where the signal is.
