Wifi unable to reconnect when coming back in range

I have this rather annoying problem with my OPO: When I'm on WiFi and go out of range and get within range of another WiFi (eg leaving from home in the morning and getting on the train where there's also WiFi) my OPO will not connect.
I've tried switching WiFi off and back on, tried forgetting network and connecting again but the network just displays as "Saved". Only thing that works is a reboot. Funny thing is that it actually detects open WiFi's and displays the question mark in the notification bar.
I've read that themes can cause WiFi problems so I haven't changed that. I'm using the Apex launcher with no visual changes.
I've rooted my phone but left the bootloader locked.
Any advice?

I'm rooted with the TWRP custom recovery installed. I had the same thing happen to me. If you toggle airplane mode on/off, it will reconnect. But, as for a solution, my fix was to restore a previous TWRP backup of my phone. I also had heard that the problem could be coming from a theme. What themes have you used? I bought the Flux theme and have been using its style and fonts. I was running the stock CM11s when this happend just a few days after getting my OPO. I would try a factory reset first. If that does not work, there is a thread in the OPO forums about flashing a factory image and getting back to 100% stock.
I have switched to the CM11 nightlies as of a couple of days ago. I will probably refrain from messing around with the theme packs for now.

Will probably unlock the bootloader. Then a factory reset should be taken care of I guess...

Anyone have a solution to this? My OPO is having this problem too and it is rather annoying...

I'm now on KTU84P and the problem is still there
Yesterday I failed to flash MAHDI and ended up clearing everything from my phone. I had to follow this guide:
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541
to get back to pre-KTU84P (can't remember the build number).
So I guess it's safe to say that my phone has had all sorts of memory cleared. And the problem is still there...

I really hate to hear that you are still having the wifi issue. One would think that if you flashed all partitions with a factory image that it would solve the problem. You might want to have a look at this thread. This guy was unsuccessful in fixing his efs and bluetooth problems until he flashed Color OS and then went back to CM. Have a read: http://forum.xda-developers.com/oneplus-one/general/fix-people-corrupt-efs-mobile-data-t2836389
Keep us posted.

Will have a look at the ColorOS thread. But I think I'll give Mahdi another go first to see what that brings me.
Thanks for the link.

Flashed Mahdir ROM yesterday and though the rom works just fine my WiFi reconnect issue has not been resolved
I find flashing yet another rom (ColorOS) sounds a bit drastic. Really no way of debugging what's wrong?

Although is sounds drastic I think it would be worth trying.

No. I'm waiting for the update to hit my phone and install it to see if that solves it. In the meantime though, I installed an app called Smart WiFi Locker that seems to keep the issue solved (for now)

Thanks for sharing. I think there are two things that can produce a major restore/fix to a phone - a nandroid restore and a major rom update. I hope it fixes yours. The nandroid restore is what saved mine.

Been there. Done that. Read the book. Got the t-shirt.
Flashed ColorOS.
Factory reset.
Booted and got through into ColorOS (skipped account setup).
Booted into recovery.
Factory reset.
Restore backup of CM11S.
No dice :'-(
What are my options now?
A couple of days ago I completely wiped my OPO - radio, modem, everything and flashed a new stock image. Nothing has helped.
I really find it hard to believe this to be a hardware issue.

Just for clarification - after flashing Color OS, did you turn on wifi and use it to see if the problem was still there while in Color OS?

If your WiFi 2.4 or 5GHZ?

Yes. I would recommend you consider doing that. If it works then I would flash a fresh Cm11s rom, not a nandroid backup. Flash the Color OS and do a full check of the Wifi.

I was having the same issue, but here's what I did and it seems to have resolved my issue.
1) Updated firmware on my ASUS AC68 router
2) Boot into recovery mode (volume down+power), wipe cache and media, then factory wipe
3) When setting up phone, did not apply CM theme on the options after logging into CM account.
It seems like WiFi might drop when you get to homescreen, just reboot phone and Wifi should reconnect. Make sure to go into your WiFi settings and remove any networks that was saved, and re-add.
Still not ideal (since it seems like themes might be killing WiFi for some users), so hopefully a new OTA update will solve this problem.

[Q] cm12 WIFI not connecting

Hi,
after installing the latest cm12 nightly (cm-12-20150225-NIGHTLY-hammerhead) I can not connect to any WIFI networks, when I try to connect it just says "connecting..." and stays that way.
Rebooting and wiping does not help. The same problem also occurs in the previous nightlies. In stock Android 5.0. WIFI works.
Does anyone have the same problem or knows how to fix it?

wlan
same problem, but don't know a solution. It seems it has something to do with the ip-adress, here it's showing 0.0.0.0 and this is wrong.

No, did it another way. I wiped dalvik/cache/data /system and when I flashed the newest cm nightly (using twrp), before I deleted the the my phone on the router (i have a fritzbox). This was the only to get wifi on my phone working again. (lot of work, but all the other ways I tried don't gave me success).

Reset the access from the device to your router. Once delete the device and then re-enable then it should go. Had the problem once, once made, never happened.

WIFI Connection Problem

Hi All,
need a bit of help as i am stuck and banging my head on the wall now... i was previously running cataclysm mod on my nexus 5 the Dec 5 variant and didnt upgrade to the later one... yesterday i unlocked the bootloader and then flashed stock rom the latest one available..
now the problem... for some freaking reason my N5 would not connect to my home wifi.. it would report as "wifi connection failure" though it has no problems connecting to the other wifi n/w( had a hotspot going with my nexus 6p and also connected to my neighbors wifi )
i did factory reset... and in the end flashed YAOSP rom my @Yank555 on my N5 just to see.. but now it wont even report as my wifi visible so that i could connect...
please help... i have tried changing the name of the wifi with no luck.. and also tried manual ip on the N5 with no luck..
thanks again
Rohit

which version on cataclysm were you running? If you were running 4.4 or 5.0 and updated to 6.0 with your latest update then it is possible there are files left behind from cataclysm. Simply try rebooting into recovery(even stock recovery if that's what you have) and try wiping the cache, and dalvik cache, and reboot. If this doesn't fix your issue, maybe try doing a completely fresh install.
To do this:
1.)unlock bootloader
2.)Download custom recovery img and fastboot flash recovery (nameofrecovery).zip
3.)Boot into your downloaded recovery and wipe all these partitions "/system, /data, /cache" then wipe dalvik.
4.)Reboot into download-mode to enter fastboot once again.
5.)Now reflash your stock img files you've downloaded from google.
Hopefully this should resolve your issue. Give me a thanks if this helped

Flash a custom recovery image so you can wipe all partitions that are included in the stock MM software. Look in your stock zip at all the fastboot img's then boot the phone into custom recovery (TWRP preferred) and wipe all partitions that are included with your stock zip. Then fastboot reflash all stock img's

Before investing money in new equipment try contacting your ISP. Tell them about the problem. If the problem is hardware based, there are numerous possibilities to fix the problem.

No problem! As a last resort just call your ISP. Comcast or whatever. They can work everything out for you over the phone.

You should have a go at enabling the old DHCP client in developer settings (see screenshot below). Could just be the new DHCP client messing with you.
As for my ROM, on HH/shamu you should be able to use ANY channel worldwide (so I see no reason for it not to see the network).
But on stock ROM (or ROMs unmodded in that regard) channels are restriced (2.4GHz channels above 11 or 5GHz DFS channels won't be usable).

It's not software. It's failing hardware. Your Bluetooth will also stop working, as it's the same chip. Mine does the same thing. I've flashed multiple ROMs and tried changing wifi system files. Nothing has helped...
Sent from my TARDIS

I bought my Nexus 5 the first month it came out. Since then I have never touched the original system or even root it. About a month ago my wifi suddenly stopped working. I have decided to root and flash roms, after factory reset and basic solutions on google didn't work. I have tried a couple of different roms all on android 6 and 7. Wifi still not working. I havent tried flashing kernel and I don't have a file called /persist in the main directory...
EDIT: Cellular data & Bluetooth working.

If changing software and resetting doesn't fix the wifi problem, it's probably a defective wifi chip. I have two nexus 5 motherboards in my desk drawer with no wifi (tries turn on but never does or turns on then off by itself) but cell and Bluetooth work.

Oneplus One LTE Issue

Dear All,
I don't know if I have posted it at the right place if I have not please guide me.
I tried my best to find a solution but couldn't that's why I am posting this.
So here I begin,
I am using OnePlus One from last 2 years and it is still working fine.
I have spent most of the time on Sultan's Rom which ran without any issues.
Recently I flashed [ROM][OFFICIAL][7.1.1_r9][BACON][OPTIMIZED]RESURRECTION REMIX [5.8.0] Rom and it worked well too.
But all of a sudden I started experiencing LTE signal drop.
I always do Nandroid backups so I restored to Sultan Rom but the problem was still there.
I have tried flashing modems with no luck.
Now I have started experiencing intermittent 3G signal too.
I have even tried restoring old KK backups but that doesn't resolve the problem.
This is so frustrating, Please help.
Let me know if more information is needed.

I'd do a complete clean restore of last official stock. If the issue still persists, it must be a hardware issue or an issue with your carrier.
If your device is wiped clean and stock software restored, there's no way it can be a software issue.
Good luck!

if clean flash through fastboot don't work out,try changing network antenna.
I don't think it's a carrier issue because it was perfect before.
The problem in network antenna must've been due to sudden drops or heavy impact.

Hi, thank you for replying.. Flashing stock ROM from fastboot is different than flashing it from twrp recovery?
Please let me know if it is.
I will certainly give it a try then.

I dont know what happened, I had flashed stock cm13.1 via fastboot.

All of a sudden the 4g signal came this morning and now I can use LTE well.
I dont know how long it will stay but seems like phone decided to bring back 4g.

Im facing the excat same issue. Did everything and nothing worked. Somebody please help. :/

Bro try flashing stock cm13 via fastboot... That will wipe your internal storage but eventually bring back 4G

I am also facing network drop issue for last few weeks.at first i thought it may be rom's problem,because generally i try a new rom in every 2/3 weeks,but now i notice that ,i am facing the issue in all roms,i read all the comments in this threads and see that cm13.1 can solve my issue.but can i solve my issue within any nougat rom?

I too am having the issue. Occasionally my 3/4g data just cuts out but it is still enabled in settings. It seems to be when I come off of WiFi most of the time. I'm on CM13.1 by jgcaap.
I'm going to flash back to full stock and then reinstall TWRP, then the ROM. I have a few issues and I figured it was time for a fresh flash.

Are you talking about CyanogenMod 13?
I clean installed COS 13.1.2 via fast boot. It even removed TWRP and brought back Cyanogen recovery. The problem didn't resolve.
Can I install CyanogenMod 13 via fastboot now? or should I unlock bootloader, install TWRP and then install CyanogenMod 13 via fastboot? Please help. I'm a beginner.

In my opinion you should unlock bootloader and then reinstall via fastboot...

I'm right now on COS 13.1.2.
Lets say I install CM 13 via fastboot and my LTE works. Can I again revert back to COS 13.1.2 using fastboot without affecting LTE again?
Thanks for the help. I will try that this Sunday and Will tell you if it works.
