HX8-C Android TV Quad Core Rockchip Wi-Fi FIX

One of the problems I found with this device was that the Wi-Fi seemed very unreliable where I wanted to position the device. I opened it up and found that the antenna is at the opposite corner of the box from where it needs to connect to inside: so the wire that connects it crosses diagonally the board hugging all the chips.

I thought maybe this was a bad idea; that all then electrical interference from the various circuitry would affect the signal - so the signal strength might look good, but the error rate due to the interference would be high.

(Warning what follows will void your warranty and possibly destroy your device - I take no responsibity)
So I decided to void the warranty. I cut the wire, removed the antenna and drilled a new hole in the right hand side for it to go in. I resoldered a much shorter length of wire back on to the board (be very careful here) and put it back together.
Not perfect but not bad and only took a few minutes. I watched a whole hour of iPlayer and only one minor glitch. Much better than before. Youtube worked fine and sounded good through the optical output.

Decided it could be improved and modified what I saw here.

I stuck the black antenna casing back over the top having removed the sleeving inside it. Seems to be a little better than last time. Device is still only connecting at between 11mbps and 18mbps but the connection seems to be solid.
