Hi all, So my phone (wife's phone ) got water damage, after battery replacement things start working except the wifi and bluetooth I think it might be the board or the cables got damaged but could not find any information where the antenna for wifi and bluetooth are and which board actually has the chip. I will try to replace the board but don't even know which one to order. Does anybody know?
PS none of the disassembly guides or videos I saw mentions the location of these.
No one has any idea where the wifi blutooth on this device?

Hello, I have a GPS issue and I would like to ask some questions related to hardware connectivity etc, i will explain what happens first:
Since i got my phone, with the stock ROM i could never find any satellites. Right now i have Viper 3.7.7 with Alex-V kernel, and it's international version S-OFF.
I opened my phone and used a tester with in the back cover of my phone to see if the GPS antenna had connectivity. And it has.
I lifted the GPS connectors up a bit to see if it was a connectivity problem, however it did not work.
I used a tester and i realized there is no connectivity between the two GPS connectors, I do have connectivity between the 2 wi-fi connectors so i do not know if there should be connectivity between the gps ones as well.
I also used the tester with one of them, and it had connectivity with the rest of the phone metal stuff, but the other one hadn't.
I used a wire to connect both connectors and tested of I could find satellites, but again 0/0
I did not sold anything because I do not know if it is a soldering problem or not. Could anybody tell me if there should be connectivity between the two GPS connectors or what could I do to fix it? It is a hardware problem for sure. I have read a lot and watched a lot of videos but i think my problem is a little bit more specifil and i would need more information about how the connectors work.
Thanks in advance.
I've been searching around for a fix to the problems I've had with my Note 2.
Basically I replaced the charging port, as the phone stopped responding to USB input. Everything worked fine but the network signal was suddenly extremely poor, often dropping calls or having no data connection.
I confirmed this was a hardware problem when I inserted a thin piece of wire into the R1 external antenna port on the back of the Note 2. This gave me 2 additional bars, but isn't a great fix as the wire needs to be adjusted frequently.
I was wondering if anyone knows what the problem might be and how to fix it. It seems like it should be a cheap fix, but I'm unsure of what components could be at fault (the new charging port, the antenna cable, a radio?).
As a secondary solution, I'd consider having an external antenna folded inside the back case, but it would need to fit and be cheap. I'm not sure if the connector is the same as the ordinary flex cable (see: http://www.ebay.com.au/itm/141170293305?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649)
Assistance is greatly appreciated. I think I've narrowed the problem down so I'm hoping someone has dealt with all this before.
my s4 mini got wet and now will not activate most bluetooth and wifi, I've tried all the remedies software but I think that the problem is hardware. I did not understand where they are physically antennas. I watched all the videos of disassembling but I can not find the ... can you help?
thanks
When taking apart my Nexus 7 (2013) LTE tablet apart, I accidentally yanked on, what seems to be, the WiFi antenna, which pulled the wire out from the metal bracket. I've been trying to find a replacement but I cannot find it anywhere online. Ive tried WiFi Antenna replacements from Nexus 5 (got them from eBay), but the wire is too short, and it doesn't seem to latch on. I've attached some photos.
Has anyone had any luck on finding WiFi antenna replacements from which I could order from?
Found this website talking about the different types of coaxial wifi antennas:

Using the reference website above, I am thinking I need the Hirose U.FL
Ordered from

I received the cable today. Unfortunately it doesnt fit/match. There are two similar cables in tablet, so I tried transferring the working cable to the location that had the broken cable. This fixed my Wifi. I haven't seen anything go wrong by doing this. I guess that's enough for me.
I've been through a lot of hassle with wanting the black back from a 3T for my 3.
I received the black back and it didn't have the buttons, camera lens, vibration switch or NFC antenna. Everything was working fine at this point with it fitted
I was unable to find a black back with all the above so I ordered a 3T gun metal back.
I received and fitted it but now WiFi and Bluetooth show poor reception to the point where I have to put the phone right next to my Pebble or WAP to get a connection.
Nothing has changed in the meantime, I now no longer have the original or black back.
Does anyone know what might have caused this?
I checked all the pins that connect to the housing antenna bands and they're all fine but still weak signal.
I've just about had enough of this, dealing with Chinese sellers and waiting hasn't been great and I just want my phone back to be the way it was. I shouldn't have bothered :laugh:
Yeah I was looking to fix it myself, I've seen the daughter boards which i believe connect to the housing for the WiFi and Bluetooth antennas on eBay for like £10

Did you solve your WiFi and Bluetooth signal problem?

Unfortunately not, I replaced the daughter board located at the bottom of the phone. The rear housing and the antenna cable. None of which resolved the issue.
