Hi, I had a problem with the dock charging,
I opend my device (htc one x [tegra3]) and found that the cable connecting between the doc and the board was not connected,
I connected it.
After I did that my phone started getting very bac 3g reception, I opend the device agien and found that I did not close one of the screws tight,
so I closed it tight and it worked great for a month, now I'm getting bad reception and playing with that screw is not helping
thank's.
solved,
one cable was not secured.

Hey folks,
today i changed the pcb of the Hox (finally managed to find a broken phone so i could use mine again).
But my wifi signal is about half it should be (i m about 1m from wifi router and there is no other network around perturbing my wifi)
I checked connector and they are ok i also changed the wifi cable but didnt changed anything. all other cables are also connected.
One thing i did was pasting a second copper isolation one the one already present, tought i would dissipate more the heat of the phone
but i won t. Now i m not sure if the trouble could come from the second copper sticker.
Did anybody got the same kind of trouble ?
Hi guys. I have a nexus 7 wifi edition and usb dab dongle with antenna. When i plug it all home and launch wavesink plus dab the signal is full green. I can move it anywhere in a house with max 2 bars lost but when i install it in the car the signal is really low between 0-4 bars max. Anyone have a clue why this is ?
The dongle i have which is second now the ebay one i bought was really low on signal.

And the antenna i use is

I have tried using the antenna that came with the dongle but its really low on signal. The one i bought is really kick ass but only home not in the car.
I have even tried to move the antenna around the car but as soon as i leave it it drops. If the tablet is out on the seat its full on signal but as soon as i put it in the dash the signal drops. Should i solder the antenna wire straight onto the dongle board ?
Hey all I posted about my wifi problem before, I have V30N D855 32 gb rooted G3, I have 2 routers at home, which my phone connects to them only when am lik 1-2 meters away from the router, otherwise I get "Saved" under the network name, not talking about wifi in public where I just end up with "Saved" all the time,
I am wondering if someone knows where is the Antenna Cable is located inside the phone itself? maybe it's an antenna cable issue that I just need to screw to get better wifi
thanks
Not sure where it is, but see if you can find one of the many teardown videos on YouTube, they show every part in the phone. I had the same problem with my iPod Touch 4g, it stays connected once it gets on but you have to be close to connect it. It does sound like a hardware issue, but the part should be pretty cheap on eBay.
Ok, I've got a old Note 3 still chugging along. The USB port was starting to get so loose I was having difficulties even with new USB cords. So I figured I'd swap out the board as it's a pretty simple swap (or so I expected). This isn't the first time I've done internal repairs, boards swaps, etc.
I replaced the old charge port board with the new one, made sure the 3G antenna cable was re-attached, and fired up the phone. All seemed fine. The connections were good and the speakerphone and mic worked (one frequent complaint of bad replacement boards). But, I was on Wifi and didn't notice until the next day that... Mobile data would drop frequently, my phone would frequently go to 4G only (something I rarely saw previously, it's usually straight into 4GLTE here in Chicago) and mobile data was very unreliable. Frequently I'd lose all bars and even if it was showing 3bars and 4G (not LTE), I wouldn't have data. I rarely do calls so I'm not sure if calls would go through.
So I opened the phone again, and checked the connections. All looked good. I used my fluke to test continuity from the ground side of the cable on the motherboard through to the pins on the USB chargeboard (where they connect to the outer back case antenna). All continuous. Resistances are all very low, even on the old board. Still messed up data and cell signal. Hmm, the lower antenna is only the 3G connection I think. Perhaps I have a bad charge board after all. I swapped the original USB board back in, but it still had the same problem.
At this point, I'm not sure what the issue is (other than I have a big problem). Is it possible the antenna embedded in the rear housing is bad or was damaged during removal? I cleaned all the connectors multiple times (first with isopropyl, then with DeoxIT Gold). I have my previous Sprint Note 3, but I don't know if the 3G antenna would be compatible (perhaps it's close enough I could use it to test). Anyone have any ideas on what I could have missed?
Thanks!
Hey (first post!)
I was replacing USB charging port flex cable by myself (and for whatever reason decided to unscrew the main board as well, but put it back in place right after). After I put everything together I noticed that my WiFi signal is extremely low. Also tried connecting to my Bluetooth headset but it has very weak signal and can operate properly within 1m distance, otherwise it starts stuttering and finally disconnects.
So I figured that I might have damaged WiFi/Bluetooth board and need to replace it. However I cannot find any spare parts for it anywhere. I only found one for OnePlus 5 but it seems that most of the parts are different between 5 and 5T.
Any suggestions please?
