I finally did what I always wanted to do: add external antennas to my 701. Drilling the holes were a bitch. First, I tried at the right hinge, but the end of the RP-SMA connector was too large. Then next to the VGA port and no luck, Oh, but perhaps next to the second USB port on the right hand side? Nope. Well, what I ended up doing was putting the connector on the outside. Check out the picture:
Edit: here's a better picture
I only have on antenna with me but the wifi reception is superb. I pick up more networks and at a greater dBm. Routing the antenna cables in the board we're that hard and I'm surprised they reached. And for the price, $1.19 on eBay, they were a steal.
