mk908 v1 - my wifi antenna is loose. How to solder it back?

[mad_cow]

Whilst openening my mk908 v1, I accidentally ripped off the antenna. Now I don't know to which point to solder it back. Can someone make a picture of the internals on how the antenna should be fixed to the main board?

I just added a post on "upgrading" the internal antenna, with some photos, as here:

Check the images - you should be able to see the point where the antenna goes - it's where I soldered the new antenna onto. Also, the board normally has "ANT" text on it, in small letters, next to the solder pad for the antenna. Hope it helps!

mmm I see. I guess I didn't break my wifi antenna then. I have pin there that connects to a metal plate in the casing.

What else could I have pulled off?
I have some sort of antenna that is stuck to casing and is connected with a grey wire. When openend the casing I remember that the wire comes from somewhere behind the microsd slot.
Is that perhaps the bluetooth antenna?

one more thought

OK, on the v1 I think there are two antennas - one for b+g and one for n wifi bands.
Remembered this image from another post, which may help:

If not, next step will be photos of your unit - both sides of the board and the loose antenna, and see if anyone else has any ideas. Mine is a v3, so appears to be more different than I thought.

That is exactly what I have. The upper part of the casing has this orange thing with grey cable and that is the one that is loose.

Judging from the pictures I have to connect it to the outermost connector next to the mini usb connector. Wouldn't you agree?

So is this antenna (the orange thing in the cover) the b+g or the n antenna?

[plinkykev]

Yes, from the photo I think the core of the cable is going to the lower pad, and the shielding is on the upper pad. Maybe just leave the case off and press the wire onto the pad to try it? Is your WiFi totally dead, or just poor quality? If poor quality, this may not fix it anyway, as they are bad from the factory, which is why I added my external antenna, which has transformed the device into something really good.

As for the b/g/n WiFi bands, I can't remember exactly which was which, but I read about it in some older article about the general WiFi performance on these units when I was looking into the issues around this.
