Add External Antenna to Buffalo WHR-G125
Increase the Router Range with an External Antenna
Buffalo WHR-G125 comes with a stock antenna permanently attached to the side. Some other routers like the popular Linksys WRT54G are equipped with detachable antennas that can be replaced with high gain counterparts. The "permanent" attachment in WHR-G125 is not so permanent after all. You can remove the antenna and install an external connector in as little as one hour [Fig 1].

There
is an alternative but more costly method to consider first.
The board is equipped with a Hirose U.FL-R-SMT antenna connector
[Fig. 2]. You could get a fitting pigtail and plug it directly
into the board. These types of pigtails tend to be expensive.

I
opted for a solution that cost me $1 U.S. at an electronics
swap meet. It's a pigtail that has bare wires on one end and
an SMA connector on the other end [Fig. 3]. Let's learn how
to do it.
