I have searched and searched and cannot find a answer to this question! I plan on using 3 WRT54GLs with DD-WRT firmware to extend our internal network out to our two storage buildings using WDS. Both buildings have metal siding. So I will need a external antenna to make the link outside the buildings. My plan was to hook an external antenna to one of the antenna ports and mount it outside while leaving one of the factory antennas connected to provide signal coverage inside. Will the antenna system on the WRT54GL function in this manner? Using both at once?
