[Q] Issues with WiFi/Bluetooth on replacement housing - OnePlus 3 Questions & Answers

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.

Where is GPS antenna

I accidentally bricked my new Rhod500 and bought heavy-used Rhod210 on eBay for parts. I replaced the motherboard, but the problem was with antenna pins, that are slightly different. I soldered wire (2) instead of one antenna and adjusted pins for second antenna (1). The GSM now works, but not the GPS. Probably, I did something wrong. Does anybody knows which one of these is GPS antenna? Thanks!
Uploaded with ImageShack.us
I figured out, (1) is GSM antenna and (2) is GPS. Everything works now, please close the thread.
there appears to be a third antenna at the bottom of the phone. what one is that? i would have put money on that being the gps.
Indeed. Maybe CDMA? One thing I know for sure, my GPS doesn't work if I cut yellow wire (2) or change its length.

Does the phone have a separate WiFi antenna?

sTUPID QUESTION.....
IS the black vinyl like sticker on the back of the phone part of the actual antenna?
I ripped mine off, and now GPS no longer works.
Hi, you mind to make it briefly probable with more details picture as i open it to solve the no sim card problem and now the gps not work.
i might have remove some weld wire or what...
mind to show me details picture how the gps wire goes around?
htc sucks....1 year and all gone
A black sticker at the bottom is bluetooth antenna.

[Q] Problem changing digitizer

Hi there.I don´t know if this post goes here.Sorry if it doesn´t.I didn´t know where to put it
I was changing the digitizer on my Desire HD and I realize that that I broke the ribbon on the picture.Can anyone help me about what to do?Thanks in advance.
Sadly been there and done that....Only 1 solution-buy another. This process is next to impossible without lots of experience-parts are very fragile! Your best bet is to buy an entire assembly with the digitizer and lcd already attached. Much much easier, but not easy by any means still. Good luck.

you can fix that.
google ribbon cable fix and follow the procedure
(can't post direct link)
btw.
this you can't fix because the lines are simply too small
(I'm waiting for new LCD)

Hi again.I change the screen but now the wifi won´t work.I can´t activate the wifi.It says error.It´s like i don´t have a wifi antenna.Any help?
wifi antenna
I think your problem is bigger than an antenna. The antenna is the same one as the gps antenna and is fitted in the panel around the flash leds. If you were to enable the wifi and just could not pick up any access points, then I would say it was your antenna, but if you are receiving an error, it is more likely that either the wifi module is damaged or somehow disconnected.
Do the rest of the radio parts work? i.e. GPS, Cell, bluetooth? Can you tell me exactly what the error is that you are receiving?

The cell,3g and gps are working fine.Bluetooh and wifi aren´t.When I activate the wifi I get an error message(it just shows "error").When I try to activate the bluetooth it just does nothing.
Thank you

You are right.The volume button are not working!I didn´t try them before.What does it have to do with the wifi?I will open it again.

not much, but it is simple test for the flex ribbon.
open the phone and check the flex connection too motherboard
worst possible thing is that you ripped the flex ribbon during removal from middle chassis
2 areas worth checking-the reciever jack at the top of the phone CAN be put on in the wrong direction-red wire should be towards the top of the phone, black towards the bottom. The long, all black wire running by the camera is the bluetooth coaxial cable and maybe not on its connector properly-kind of pops on when right-check both ends. It also could be damaged/pinched running up through the phone. It could also just be a bad component on the upper board and that whole board needs replacing-a pain after what you've done already.
bluetooth/wifi and volume buttons not working
I think yamFZ6 is right. You likely have a cable not fully seated or a damaged cable. Both the Bluetooth and wifi are on the same chip so it makes sense that both of them would fail together, the volume buttons are a separate module, so they are likely all on a single cable that has issues.
One last thing to try before tearing it apart again, do a full wipe and see if it works properly. This is a long shot, but worth checking and can help with troubleshooting if you cannot find any cable issues.
Good luck,
Let us know what you find.

Looks like the black wire (blue tooth coaxial) near the camera is in toward the battery area too far...battery would be pushing in on it every time and could have broken it...admit that's a long shot...but. Starting to feel like a new "upper" circuit board is in order...hope this helps

Do you know where to buy it?
I have seen it for sale somewhere out there but can't find out where that was now. I would look for a "parts" phone on ebay. usually you get more than a fair amount of usable other parts with it. I just did this for that exact issue plus I needed a 'mid frame'. I got just about everything else with it also as the lower, main board was the problem with that particular phone, Got a usable digitizer, lcd, case, extra wires, camera etc etc all for around $60. You also get the added luxury of more practice/expertise with assembly.

[Q] Where is the WiFi antenna located?

Hello all,
For over six months, I have had a WiFi issue with this tablet. I must have dropped it or something because the LCD ribbon came loose but that was easily fixed because other people had the same problem. Unfortunately, I have absolutely no idea where the WiFi antenna is, so I am asking for your help. If someone can provide a detailed picture of it, I would be grateful.
Also, I have absolutely confirmed that this is a HARDWARE issue not a SOFTWARE issue.
Thanks in advance,

if you place your tablet facing down and the camera on the top pointing at you the antenna should be on the upper left hand side.

I had the same issue after re-attaching the LCD. I ordered a new back cover. There is a wire that runs through it that i must have severed when removing the cover. When i had it apart, i also removed the speaker to visually inspect it. I slightly lifted the pogo connectors under the speaker and that connect the back cover antenna terminals. I popped on the new back cover carefully, powered it up and boom... perfect wifi reception.
Good luck.

So I have learned that the rear case is integral with the wifi antenna. upon inspection of my own unit it was missing these contacts that indeed make contact with the speaker/antenna board. This unit was serviced by Samsung for a dead screen under warranty and came back without the contacts on the rear case. They must be easy to dislodge and whoever put it back together wasn't watching what they were doing.

[Q] Where Can I Find a WiFi Antenna Replacement?

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
www.gridconnect.com
[11/19/2014]
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.

ZENFONE 2 ZE550ml very poor wifi and bluetooth signal.

Hi guys.
I'm having big trouble here with another zenfone 2 ZE550ml.
(It was left switched off for almost two years!!)
Now when i powered it up!
I noticed that , It's WiFi and Bluetooth signal range has become very poor. It has become so weak that
The WiFi bar shows full only next to the router but no signal at all in a few feet (2-3) distance from the router.
And the Same condition for the Bluetooth too.
I have tried resetting several times but no result.
(My SIM connections are good as new Though!!! They are fine!!)
Here is some info,
[After resetting.
The firmware version was.
2.20.40.9(something)
Then auto updated (150MB) to
2.20.40.120
And some minutes later,
It took another auto update (91MB)
To 2.20.40.156]
I thought it would help, but it didn't do anything!
The WiFi and Bluetooth is still in the same condition.
(Very weak signal. Becomes strong only when I put the phone on the router !!!.)
Please help.
Is there any way it can be fixed ???
(Is the device's WiFi & Bluetooth chip got damaged??
How do I check if they are?)
Maybe the wifi antenna has come off. You need to remove the back and the screwed on backplate. It connects in the bottom right corner by the vibration motor.

Thanks for the reply.
Did you mean that black wire which comes from the motherboard to the Board that has the USB port?
I'm sure that the wire is connected.

If it is the cable.
Then I am sure that its properly connected.
Though, still there might be problems.
I will check it out.!
BTW,
Are you sure That the coaxial cable is the WiFi antenna?
I mean it could be the Mobile network antenna.
As my phone network is doing great!
And where can I get a full diagram for this device ?
I mean "what part is for what" in this device!
Thanks.

Hi everyone,
I have the same problem. I recently changed the screen and I though it was a complete success but no. Wifi and also bluetooth works as you describe.
I think I probably broke the coaxial antenna cable or maybe it's related to the usb+bluetooth module. Any solution idea of how to fix it?
Should I change the cable?
Thanks

The WiFi/Bluetooth antenna are on the top of the motherboard near the power button. Check the spring contacts there. Gently lift up those contacts if they are depressed and make sure the rear cover contact points are not corroded. If corroded, scrape them off and you should be good to go.
