I upgraded the wifi adapter on my X230 from an N-2200 to N-6205. According to the service manual (linked below, page 68) I should have 4 antennae (grey and black for wifi, red and blue for wwan). A 5th antenna (white) is present only if there is no camera. Mine has a camera, and no wwan card. http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/0b48666.pdf I opened my laptop up and I only have 3 antennae in there - grey (connected to N-2200), and red and blue (capped, not connected). Does anyone know if I can use one of the WWAN antennae as the auxiliary for my N-6205. Right now I only have the grey connected, and windows connection properties shows 150 Mbps, not 300, indicating that only 1 antenna is in use. Do I have the option of installing the 4th antenna myself?
