Can you share the process of contacting LG for getting the logicboard replaced? The CC I paid with two years ago extends the manufacturer warranty by another year, so I'll have about another month to get it serviced and then reimbursed.

How has the repaired one working for you so far?

Just wanted to say that I had this issue, and nothing in this thread worked. However, I tried removing the mainboard from the phone and baking it in my oven at 350 degrees for 3 minutes. After reassembling the phone, it works perfectly again. WiFi can go on and off with no problems.
[Nexus 5 Q&A, Help & Troubleshooting] Chefov01:
Can you give us some details about baking the mainboard? I'd like to try this method, I don't have anything to lose! :D
[Nexus 5 Q&A, Help & Troubleshooting] shaklee3:
Take the phone apart and remove the main board (the large board above the battery). It has about 5 connectors plugged in. Remove your SIM. Preheat oven (I used a toaster oven) to 350 degrees, and put the board in on a crumpled piece of foil so there's plenty of airflow all around. Bake for 3 minutes. Remove it and let it cool down. Reassemble phone.

It's been 4 days, and so far, so good. I'll let you know if anything changes. By the way, I was like you guys. Nothing worked and I was at my wits' end, and really needed wifi for work.

People have had great luck sending to LG. While it's a bummer to be without your phone for a few weeks, LG completely repairs your phone for under $50 no matter what. (Assuming no obvious physical or water damage) It was painful to use the $15 windows mobile phone, but I got by. LG offers two price options. $45 repair or $195 refurbished. I chose cheapest route and got a totally mint phone with my old imei on it somehow. Even had the little plastic to peel off. They even paid shipping both ways. My phones sim card slot, Bluetooth, wifi, battery, and power button had issues. I told them my battery gets really hot and afraid it will explode too for giggles. Boom done. My phone was a release day phone way out of warranty. Just call LG and get it going. I wish I hadn't wasted so much time trying to fix myself....

Tldr call LG, send phone in, authorize cheapest $45 repair option, get mint phone from LG.

One more question [MENTION=4299370]shaklee3[/MENTION] ... baking your motherboard at 350°F for 3 min did not kill anything on it, like the front camera or the flash led for example ?
[Nexus 5 Q&A, Help & Troubleshooting] shaklee3:
Yes, everything is normal. Keep in mind that the camera was NOT in the oven. Only the mainboard with the flash, radios, etc. The actual lens, cabling, and sensor were not in the oven.

I called LG and they wanted $135. I probably would have done it for $50, but they didn't offer it. Luckily it ended up costing $0.

I didn't get an immediate price over the phone. I had to ship it. About 3 weeks later I received an email with the quote and 2 options.

This worked for me

the solution from page 12 of this thread worked for me:

-------------------

"So I go in with root explorer, delete .macaddr file, and run these commands (the first line is my mac address being set, because I know what it is already; obviously you'll need SU to do this):

echo -ne '\x8c\x3a\xe3\x41\x8d\x79' > /persist/wifi/.macaddr

chown root:root /persist/wifi

chmod 755 /persist/wifi

chown wifi:wifi /persist/wifi/.macaddr

chmod 660 /persist/wifi/.macaddr"

----------------------

I had tried just about everything except baking the motherboard. I had already deleted the persist/wifi folder in a different attempt to fix.

Added it back with Root Explorer, then made a .macaddr file and entered my MAC address with the editor in Root explorer. Changed the permissions as listed above, rebooted and BAM..working again.... props to the folks on here helping others!
[Nexus 5 Q&A, Help & Troubleshooting] DerEmryz:
Did any other folders get created except the WiFi folder? If I remember correctly, there should also be a Bluetooth and sensor folder in there. Either way, did you use adb or a terminal emulator on the phone?

[Nexus 5 Q&A, Help & Troubleshooting] YoannS:
Well... after trying each solution described here at least twice without success, I tried baking the mainboard, 200°C (392°F) for 3 min. Did nothing (cannot connect to wifi and wifi chip overheating and draining battery).

Few hours later, I changed the protocol and baked it at 200°C for 8 min. Now I think the mainboard is dead since the phone is not turning on at all anymore and the wifi chip is overheating just by pluging back the battery on it.

It was definitely a hardware problem for me.

I contacted LG (without mentionning my cooking skills ofc :D), and they asked me to send my phone for repair or change. I hope I will have more luck with this...
[Nexus 5 Q&A, Help & Troubleshooting] fridaycoffee:
-so i contacted lg....200E for mainboard replacement...i said no :)

- i was tempted to try the baking method but after the last reply..im kind of circumspect

- last solution would be taking to a specialist to try to glue the mainboard again....he said that it's a hardware solution caused by a software problem..and that i should wait for a software update...but since 6.0 didnt solved anything...i'm kind of puzzled.
[Nexus 5 Q&A, Help & Troubleshooting] YoannS:
[MENTION=6985124]fridaycoffee[/MENTION] I think my wifi chip was already almost dead before trying the baking method (it was overheating so hard that my phone was turning itself off to protect the mainboard). Basically I just helped to kill it for good.

If yours is not heating that much, you can try the baking method (200°C/392°F, for 3 min).

Carrie Question?

Carrier Question?

I know carrier doesn't have anything to do with this, but why not ask. I think everyone is looking for some type of pattern to poke it's head out of the garbage. I have been on T-Mobile for the past two years. I got rid of my home internet connect and was using up to about 20 GBs of data until the Wifi stopped working. I really loved the hotspot feature, but since about last November I have been hotspotless because this doesn't work properly. I have also always wondered if the Wifi on the phone would work without a battery just hooked up to an outlet since part of the problem seems to be the phone overheating. I can't wait to buy Nexus Protect when I get the Nexus 6P, so I can call and complain to someone that has to pretend to care when Google decides to install a junk OS.

[Nexus 5 Q&A, Help & Troubleshooting] phinal:
my N5 died on me quite a few months ago ... around the time I was flashing the some updated factory images of lollipop onto it.

the wifi wouldn't ever work, and after trying to fix it for awhile, it began rebooting every time the screen was turned off (either manually or because of the turn screen off after #mins setting). so i left it rebooting and finally the battery died.

i set the phone aside and didn't touch it till the marshmellow factory images came out and thought i should give it one more try. so i charged it up, booted it, and it immediately connected to wifi and said there was an update available. it downloaded a 5.0 update, restarted & installed, booted up again, downloaded 5.1 ... then 5.1.1 ... then 6.0 ... and somewhere in there a security update or two. and now basically i have a functioning phone again for no reason other than i let it drain down and sit for awhile.

no clue how long it will function, but i'm just surprised to have it come back to life again without me actually doing anything to fix it. it isn't my primary phone, so i won't be stress testing it or anything ... it is currently my backup if anything were to go wrong with my N6.

Same experience I had, except I had to pay $195 out of pocket (which I plan on getting reimbursed through my credit card's extended warranty protection). The second time I sent it back, I included printed out screenshots of the problem, highlighting the MAC address and everything. The packing slip stated the same thing, that the problem was "Searching for SVC" and the resolution was "download new software". I am on the phone with them to send it back a third time.

If it still does not get resolved after this, I am planning on filing a complaint with the BBB, as well as filing a chargeback with my CC for the cost of the repairs. To do so, I will need to obtain a couple of quotes from local shops showing their diagnosis that the phone still needs repairs. On top of that, I will be filing a claim through the extended warranty protection under the condition that the "phone cannot be repaired".

Just to add one more unsatisfied customer of Nexus 5.

About week ago I noticed that my phone got really hot all of a sudden! And that night battery from 55% status, over the night dropped to under 10% (after maybe 3 hours).

WiFi worked all good. Phone was at Marshmallow , latest OTA update. First I taught it was battery problem, but I read it that it maybe was the problem with Android OS. Some customers told that they downgraded to 5.1.1. and battery came to life. So did I. From 6.0 to CM 12.1, but problem still remain.

Before I went to sleep, I turned off WiFi and that was it! Since than, no more WiFi or Bluetooth.

I tried several suggestions from this thread, but non of them worked for me. I'm prepared to switch motherboard with new one in my expense, because my warranty expired. :(
[Nexus 5 Q&A, Help & Troubleshooting] Zgembo:
baked!

Just to add my little piece of experience with this issue. I got Nexus 5 from a college of mine with a note that WiFi does not work at all. Software problem I thought, nothing I couldn't fix myself...

But it turned out to be a real HW issue, cause no messing with flashing numerous stock and custom ROMs in various order, or messing up with firmware or persist partitions ever helped.

Baking the motherboard in a gas stove on 185C for 180 sec sharp did! Since I never intended to use Nexus 5 as my main phone, I attempted to try this risky baking thingie...

I've placed the bare motherboard on a flat piece of aluminium foil, supported by four little aluminium rings (allowing airflow below the board), WiFi chip facing up, and with that yellow EMI shield/wireless charging/NFC board removed (bottom shield remained in place).

The solder around WiFi chip seems to got re-flowed correctly and I have a fully working phone in my hand now. Thanks to those that gave a suggestion in a first place!

Not sure what do you mean by "brown circuit board" behind the memory chip, if you talk about that brown-yellowish metal shield around SK Hynix RAM, the answer is no, it went into the stove. I quickly searched for images that best resemble the sate the board was when i had put it for baking, check these:

[Nexus 5 Q&A, Help & Troubleshooting] Zgembo:
[MENTION=4673498]audit13[/MENTION]

Yes, I definitely removed everything from the upper side. That brown circuit board is NFC & wireless charger, it is glued to the metal shield, so you only need to disconnect the thing and carefully remove the big shield. Make sure you remove the small shield on the left side as well, that is where the WiFi chip is, you may want to expose it. Finally, don't forget to remove that camera, it will most likely melt @ 185C :) And remember, you are doing this on your own risk.

The defective wifi motherboard I have has been replaced with a functional motherboard. I know this is risky and don't really have anything to lose since there does not seem to be any other way to fix it.

[Nexus 5 Q&A, Help & Troubleshooting] sucro:
Zgembo above wrote, there is many options to try from factory reset, wipe/factory reset, wipe cache partition, downgrade to radio 4.4.2, flashing stock rom once more (even stock was on my phone 4.4.4), modifying .macaddr with correct MAC, deleting persist and recrearing, deleting wifi and bluetooth folders inisde "persist", and recreating through terminal by giving them appropriate permissions, and creating new .macadrr .bluetooth files with original MAC adresses of my phone, safe mode, etc etc. , but nothing of those above didnt fix my problem freezing totally of phone when turn on Wifi.

This started happens few days ago, suddenly battery started discharge so fast in idle, 5h using - max, 8-10h idle and turn off phone, thought some sw problem, some of apps drains battery, or some corrupted system files, like .macaddr, etc. , so tried all possible sw options, but no one fixed...

GSM and 3g, LTE work ok, but Wifi whole time freeze phone when turn on it, and then phone goes in non-responding state and reboot it, it stops reboot only when turn off wifi... Checked 2x antennas white and black under back cover, both are connected ok, seems those antennas are for 3g and LTE,not wifi, cause guy from this greate dissasembling nexus 5 video bellow,

https://www.youtube.com/watch?v=OPuCmfhzgbg

mentione 3g, and 4g antennas...

Seems wifi module is directly on MB, no any antennas... So, if this problem directly connected to wifi module-chip, solution = replacing motherboard, or some try baking their MB, maybe that just fix problem temporary, and that will happen again soon, or not, didnt try, so can't judge...

Logic mb which is still too expensive, even used about 120 to 180$, so not rationally, for used phone, buy 150$ mb, if used Nexus 5 is now 200$, even less...

Good luck to all of you, to fix your Nexus 5 wifi problems!

******Update

For all of you with this problem, solution is not only to replace whole motherboard, cause still too expensive, but to find some experienced mobile-servicer, to replace wifi chip on motherboard, chip you need is bellow ,

I am also having this issue. Trouble is, I bought my Nexus 5 off of Amazon.

I tried every solution in this thread, but WiFi continued to be intermittent. So I sent it to the seller (in China) for 'repairs'. They kept it for about 5 months until I replied to their email, when it turned out they actually still wanted to know if I had other issues (due to the email looking like they were fixing it and then sending it back). So I replied again, telling them there were no further issues, and my phone arrived at my doorstep after a grand total of 7 months. Not fixed at all :mad: (they didn't understand intermittent, I guess).

At this point I think I'll just sell it on ebay, and spend my money on a OnePlus 2 (where all bugs seem to be software-related, and easily fixable).

reflow

My two cents:

had the WiFi issue -- couldn't turn on, phone reboots on sleep, etc.

put it in the fridge 10 mins, WiFi worked for a few mins afterwards -- seems like a soldering issue...

attempted a heat-gun reflow exposing only the wifi chip (foil over the MB), slowly getting temperature high enough to melt little piece of solder I held with a vice-grip in my blow while monitoring temps with infrared reader. Let cool for a while.

wifi chip now works, no more software issues / reboots etc.

Definitively not a software issue on my side :)

Risky but in my case, worth it :)
