Hi,
I have a Alfa AWUS036NHA USB wireless adapter. I'm currently using the standard 5dbi antenna that comes with it. Unfortunately this doesn't seem to be providing the signal strength that I am looking for. I can get the 9dbi antenna but not sure if it will make such a difference. Currently getting between 12 - 24db in an airodump session and wanting/hoping to be able to increase that if possible. Any help would be appreciated.
