Booster as in repeater? because depending on the type of card yes you can as long as you set it to be a base station all traffic would forward to that and then onto your destination. Or as in actual reapter mode which some support which acts the same way as a base station. However would be better suited some where in between where you are and the access point/router/gateway is located.
Repositioning your aireal on your wirelss router/switch to a more downward angle may help with the signal reception, if that is how your system is setup.
