http://www.slatedroid.com/vbulletin/showthread.php?308-M003-PCB-pics[/url]!I have board version 5, and will try to post picts in that thread later, but it has the same USB WiFi.The WiFi is the separate board above the batteries in the V_2 board picture. It's basically a USB WiFi stick, with the connector removed, and wires soldered in place.Mine has long wires, as in the picture of the V2 board, but in my machine, the connector is much closer to where the WiFi Board is. The wires were looped right over the board, very close to the antenna. The antenna is the bare copper paths in the non solder masked (not green) part of the WiFi Stick board.I did the
following:1. Open the Unit (your own risk)2. Coil/Fold the wires away from the antenna area.3. I turned the WiFi board upside down. This moved the antenna paths farther from the metal box around the screen.4. Move or Remove any labels that are touching/near the antenna. It's possible they have a metallic substance in them.5. Make sure the WiFi stick cannot short against the metal or other boards.6. Reassemble.I got 1 more bar signal in most areas, and it will now connect in places it wouldn't before.Actually adding a better antenna may also help (perhaps one from a laptop or other device). There's plenty of room in there.
