    Hi stillsomber,
    if your Device is M9 Max with one Nandflash,under Current Pipo Roms on Page 2 you can find what you need,but read first,before you go to flash.
    Wifi problems,first read this Thread and on Arctablet all important Threads,but normally you only have to desolder Ground or change cable.

    good Luck

    Thank you for your help tpapo!

    What should I do with far end of No.2 should I desolder and move it closer to No.5 and use sticky tape?

    Confused what to do

    Hi people! I (more than my tablet) am suffering from it's wifi connection losses. So wifi drops randomly regardless of the settings, even after official ROM flash to 4.2.2. that made the OS more usable but NOT wifi. I was reading posts on this thread and got confused because the YT videos don't seem to match my situation.

    The photo is attached but just in case here is the original:
    http://www.chaos.com.hr/res/pix/pipo...isconnects.jpg

    For starters I don't see anything large connected to the motherboard that would justify insulation tape and cardboard. The silver thingy numbered as 3 is that sticky tape an actual connection of the Wifi antenna because it looks like that under 5 is the antenna.

    If just simple insulation tape fix is out of the question for me should I re-solder black wire number 1, 2 or 3?! Or should I disconnect one of them. One end of wire No. 2 is connected to the outer shell where speakers are mounted.

    Let me just say that my WiFi signal reception and speed are fine for my needs the connection drops drive me crazy!

    ONTOPIC:
    X1. If I need to replace one or more of these black wires I should look for coax wires when I am buying new ones? The point is not in the thickness of insulation around the copper but about RF shielding around it?

    OFFTOPIC: Other questions that are not so vital to me but still thank you for your answers:
    1. How to improve GPS signal reception?
    2. Where is the internal SD card situated? Is it soldered to the MBO or removable?
    3. When my batteries start loosing charge from old age and multitude of recharge cycles where do I get new battery packs? Are the ones used standard form factor? Also are they replaceable with moderate skill or is it very touchy and complicated and people should rather buy a new tablet?

    I am asking all this because it's been a year since I bought this tab and for the grief it gave me, after I fix it I plan to ride it until the caps explode!


    Thank you for all your help!

    Fret not, if you're not good with soldering or want to be "less invasive", you can use the papercard/tape trick:

    Most people don't have that problem....there is just a percentage of tablets that make it off the assembly line with crappy soldering connections to the wifi antenna. Rather than spending $50 to send it back...it's just as easy to re-solder it yourself...if you are good with a soldering iron.

    +1 here for the "finless method". I just removed the ground connection (the shielded part) of the cable, and I had a huge improvement both on connection quality and stability. Should I add the "tape method" for further improvement?
    Thanks guys, you really helped me.

    It's made a world of difference on my M9 Pro.

    Thanks again!

    I had the same problem with the WIFI as everyone else. Couldn't stay connected for more than 15 minutes, sometimes it would drop after 30 seconds or 2 minutes. After reading all the posts here and other forums about replacing the wires, yesterday I thought I'd give it a shot.

    Before replacing the wires, I wanted to try something I read elsewhere (where they said there's no reason to replace the wires).

    I unglued (not unsoldered!) the wifi adapter from the case, cut a piece of thicker paper to fit between the case and the wifi adapter and placed it between the two. Then I put the adapter back in the original position (on top of the paper), put 3 stripes of insulating tape (image below) over it to shield it(?), and the original scotch tape that was over it.

    WiFi fix.

    Just wanted to say that this method works (opening it up and replacing the wires to wifi and insulating the antenna).

    My wifi went from 5 Mbps to 65 Mbps after doing this (-52 db)
    Did this 2 weeks ago and not once has it disconnectet from the router and is now very stable.

    Thanks all you people for your tips and trix
