Some time ago I added a high gain antenna
to my wireless router and it made a noticeable improvement to the
performance. I have just upgraded the router and it has three antennae
instead of one
<http://www.asus.com.au/product.aspx?P_ID=WAa6AQFncrceRBEo . If I
substitute my high gain antenna for one of the supplied ones what
effect will it have on the range and/or transfer speed. I am assuming
that if I substituted all three then I would improve the performance.
Re: Wireless router antenna
Your new router is 802.11n. The idea of n is that it relies on multiple
carriers to get throughput, and in some case this relies on multipath (or
spatial) effects. It's possible that not all antennas will have all
frequencies associated with it, if you put an antenna on one port and not
the others you may actually reduce throughput. So if you must, change all
three, not just one.
Unless of course you are ONLY using it to connect to b or g devices, read
the manual - it may offer a b and/or g mode which forces the router to use
one port, in which case the answer then would be yes.
