First follow these instructions to open your WHR-G125.

Unsolder the stock antenna wires from the board. You should use a solder vacuum sucker and a soldering iron with a sharp tip. You don't need a lot of heat. The onboard antenna connections are in close proximity [Fig 4] to each other and it's easy for the molten solder to jump the contacts. If this happens don't despair. You have not ruined the board. Just use the vacuum tool to remove excess solder.

Depending on the type of external connector you intend to use you could drill a hole in the router enclosure and mount the connector there. I decided to go for a non-invasive option that consists of taking out the original antenna and placing the connector in the hole where the antenna was attached.

To remove the antenna squeeze the tabs as indicated [Fig. 5] and pull the antenna away from the router.
