Modding my MK802 IVOriginally from June 2013
Well I call it modding, but <5 minutes doesn't really make a mod...
However doing it resulted in a 8-10 fold increase in wifi throughput, so well worth it!
You can see the finished article and the device opened up...
If you want/need to do this, open it up from the HDMI connector end - carefully with a "precision" screwdriver, once you've got it started it should come off easily - I didn't break any tabs taking it off... Also take the SD card out before starting...
Pic 3 shows the tools I used.
Now take the board out of the case, you'll see a red and a black wire (I think the red wire is Bluetooth, but not sure), its stuck to the back cover with some metal tape and some translucent yellow tape.
I used the scissors to make a small incision in the bottom of the case where the ventilation holes start, and clipped off a small area of the tabs from the top half.
The cable then neatly fits through the hole... I also made a matching slot in the foam so I can easily transport the unit.
Don't be tempted to fold the metal tape over on its sticky side, this seems to shield the effective part of the antenna, and results in even lower throughput (<.5Mb/s when I did it!).
Download speed is now 20-25Mb/s, upload is still under .5, but importantly latency to it from another Android (running Fing) is less than 10ms, with 0-1% packet loss compared to 30-40% before the "mod".
I wonder if getting an external antenna for it to "cover" the wire is worth it?
Also wonder if I should take the metal tape off - could this effect upload speed?https://plus.google.com/photos/102221067073073008496/albums/6104923232801337169?authkey=CMrgjvHGyIW5DQ
