Wi-Fi and bluetooth not working. - Xperia Z3 Q&A, Help & Troubleshooting

Hey guys I have d6603 and some time ago my Wifi and Bt stopped working for no reason. Soon after my phone just died (sudden death,but I was able to resolve that matter). The wifi and Bt problem still haunts me. Do You have any ideas what might have happened? I did root, unlocked bootloader, flashed some custom roms afterwards. I thought the chip burned, but for some reason after I powered up my phone from sudden death, the wifi was normally working for about 1 minute and then died again. That would exclude the burned chip I think (I may be wrong ofcourse).

[Q] WiFi switching off

Hiya folks,
Bit of weird one here. I can't seem to switch on my WiFi anymore. I turn it on, it tries to enable, but then switches off without any interaction from me. I've done nothing different, software wise, with the phone over the past few months. I did, however, take a 2 hour drive the other day with strong sun coming in the window. I had been using the phone as a SatNav and I'm wondering if maybe it over heated and killed the wifi chip or something. Is this familiar to anyone? I've never heard of it before so any help would be great.
Thanks a million,
T
What rom are you on?
Have you tried a full wipe? maybe try to re-flash if problem still persist or test with a different rom.

[Q] 3G not connecting after screen change

After flashing CM12 on my nexus 5 (D821). I flashed the 20 jan Nightly and everything was working fine untill i update to the 22nd jan nightly when my 3g simply stopped connecting or had very spotty signal, i didn't give it much thought at first thinking it was a nightly problem but after one week i reflashed stock lollipop, locked the bootloader, even tried kit-kat and the problem is still there. Before flashing cm 12 2g/3g/lte switching was working perfectly for about one year.
So utill now: i flashed different stock rom's, different kernels, radios, custom roms and nothing worked. When i tried switching the sim with another one from the same network, 3g worked on the other phone so i doubt that the sim is defective, but on my nexus i had the same connectivity issues. I also played with the *#*#4636#*#* menu and managed to get 4G working again but only in CDMA mode and I cannot receive any calls or texts, but the internet connection is working, 3G also connected at some point but the signal was very poor.
I am lost now, and also desperate because edge is too slow for anything. What confuses me though is that this seems to be a software issue since the cause was me flashing a different ROM but all the signs point to a hardware issue.
Can anyone plese give me a second opinion? Is there any fix for this? (Also i recently went to my network's service to replace my screen assembly, could also this be an issue? the issue appeared about 2 days after getting it back from them, also about the same time i flashed cm12)
Thank you for your time.
Also another thing i just noticed:
I opened my phone's back cover and the writing on the frame covering the motherboard says D820 and in the bootloader my phone shows as D821. Is this common for every D821 model?
I started to wonder if i got all my components back from the phone service... Although it's highly unlikely that they mingled with the motherboard since everything that i had on my phone was still there (custom ROM and all my personal info) maybe they switched the antennas...
Is the antenna connected?
Im going with disconnected antenna as well.

wifi in Nexus 5 not working - marshmallow

My wifi is stuck on "turning on" after getting reset multiple times automatically. I have the logs. How to attach ?
Does wifi work with any other ROMs?
I have the same problem... And now i played with my device and figured out that my mac address is 02:00:00:00:00:00... And after a while it is normal... What about that, is it possible that wifi antenna is faulty, not the chip...or motherboard... Because everything works normal...
If the phone has never been dropped or bumped, it's unlikely there would be a problem with the wifi antenna but it is possible that so,etching came loose over time.
I suggest trying a couple of other ROMs to see if wifi works. If it still doesn't work, dismantle the phone and look for loose connections. If everything appears fine, i would conclude that the wifi chip is defective.

Signal problem when connected to Wi-Fi

I bought an OPO with cyanogenmod to my sister a couple of months ago. Since the beginning, it has a very weird problem; when connected to Wi-Fi, every some time, the opo totally loses the phone signal, and then gets it back. Sometimes it happens very quick. I have seen more people in a Spanish forum using an OPO with the same company as me (pepephone, using movistar).
I contacted oneplus and they made me reset the phone, but it didn't solve the problem. So now they offer me to pick it up for repair.
I think it's a software problem, without Wi-Fi connected it does not happen.
Can I try cm13 or other modems and still keep the guaranty? If so, what should I try? I don't wanna mess my sister's phone too much, so I would prefer to leave it stock.

As of today I am having the same issue; I have tried multiple networks to no avail. Booting into safemode and turning on/off wifi does not work. If I find a solution I will update this post accordingly.
Me too. I believe it happened after I installed the May security update.
Just started happening to me about 4 hours ago. First it went in and out a couple times but I was within say ten feet of the router. Now I'm one room away, but have line of sight to to the router, and I have no Wi-Fi connection. It will come up as poor with no reception and then connect but never get internet. LTE works fine, wifi worked fine all day even.
Not working WiFi. I can not even turn the WiFi tumbler ON, some security updates Fixed Bluetooth. Do you guys have the same issue?
My wifi also stopped working. I was on P beta and it was working fine but yesterday simply stopped.
I rolled back to 8.1, same problem. Rolled back to 7.1 and nothing.
It only gets wifi if place my phone on top of my router.
You guys think it is hardware related? Because it didnt fell or anything, it just stopped working overnight.
Same, it happened after I upgraded to P
My wifi stopped working too. I tried everything.. it will not connect to any wireless access point anywere
I tried going back to stock image 9.0 and tested NDE63V (Standard) and still nothing.
I get and see signals but fails to connect.
any ideas?
dam...this sucks..time to dump this pixel and buy something else
I looked on eBay.. a few listed as Bad WiFi
Apparently it's fairly common on eBay and on the forums with no fix for it
