The range on my x5 was so bad I would lose signal from the other side of my garden 30 0r 40 ft away. This wifi router antenna from ebay is one of the upgrades other owners have found to work well. The 5 way charger was another problem as my usb charger only supplies 500 ma and charging was taking too long. With this upgrade I just took the little control unit from the plastic case and swapped the charge socket for two wires that I can connect to a variable current power supply while still keeping the auto cut off.
