I was wondering whether I can use an external antenna to increase the speed of a internet connection. Its not something which I plan to do, but its a general query which I have. If its something which works well it may also be considered in the future. I see a lot of places where they sell antenna's so I thought if they are on sale they must be good for something.
Antennas dont increase the internet speed but only make signal better. Technically thinking then you can say it increases the broadband speed, as if the signal is good the speed is good, but it would be the maximum speed which you are paying for.
