Wifi just scans and never connects

I just upgraded to 5.1.1 ...I posted an update http://forum.xda-developers.com/showthread.php?t=1008702 to my post but assumed most never saw it....
anyhow....ever since moving to the update my wifi just spins. It recognizes that there are services available but it never gives me an option to connect to them. Any ideas?

after a sleep? or after upgrade to 5.1.1?
I have encountered this issue before on tnt lite 4.2. I simply rebooted it and reset your wireless router. and then no issue to me.
check out this thread if it is after a sleep.

I don't 100% remember but I think that there is a custom kernel to fix/improve the wifi problem? Anyone can confirm it?

There were some issues regarding sleep (mostly failures to wake, causing reboots, and CPU throttle getting stuck on sleep).
However, those on the 5.0 TNTl are stuck with the existing kernel. Not to bash TNT - I've used 4.X and 5.X versions and think its great - just that it's in its own little world as far as kernel and recovery options.

no sleep...just straight after the update. I have searched the forum and done anything that looks like it might work. Reset the router several times, stood within 6" of the router. Re-booted probably 100 times.
I went back and cleared the darvlick cache and did a factory reset. Re-installed 5.1 thinking this might help but from my noob eyes it looks like 5.1.1 is still running (based on the background wallpaper only).
That is the frustrating thing for me...if this happened on my pc I would go get a new driver or reinstall the hardware and I would be back up and running...with Android and ROM I am completely lost.
++UPDATE++
Just checked into the hotel and the wifi works on an open connection. I really don't want to open my home network if can avoid it...typical suburban cul de sac with too many people that would to steal some wifi

Nexus 5 problems after updating to 6.0 Marshmallow.

Well, I've updated my Nexus 5 about a month ago when I got the OTA. After the update I made a Factory Reset, and installed all the apps from scratch as I usually do. My phone has never been rooted, or had the bootloader unlocked, or anything... I'm just a regular user. I've been experiencing the most frustrating problems ever since the update. I've never had this many problems through Lollipop or even KitKat. I'll make a list of the things I've noticed:
- Battery Life got worse. I just don't see any improvement at all. With 5.1.1 I got to work with 100%, and when I got back home, about 85%. Now I get home with 75% - 70%.
- Problems with WiFi. The first 2 weeks using Marshmallow, I've noticed on the Battery Settings that WiFi was using between 25% - 45% of the battery. Usually on 5.1.1 it used between 1% and 5%. I solved this making a Factory Reset and a Wipe Cache Data from the Recovery Mode. Also I disabled both WiFi and Bluetooth Scanning from the Location settings.
- Settings app crashing when trying to access to "Data Usage" settings. I had this problem on Lollipop too. It solved itself after updating to 5.1.1 but it came back on 6.0. I solved it making another Wipe Cache Data from the Recovery Mode.
- After fixing this other two, I've started noticing problems with the Proximity Sensor on calls and Whatsapp while listening to audio messages. I haven't solved this one yet, but I don't care much about it.
- Apps crashing, particularly Google Photos and sometimes Instagram (when trying to take a photo or a video from the app, I didn't have any problem when uploading from the gallery.).
- Slow charging or even discharging. I usually plug my phone at night to the wall adapter. Every once in a while it charges really slow or even discharges. I have no idea if it's the battery itself, or the microusb connector. I even bought a new wall adapter, and the problem persisted. THIS DIDN'T HAPPEN ON 5.1.1!
I'll try to upload screen captures and more details later. I know many reported some of this problems before so please, comment and help!

Hello !
You can solve all of your problems very easily !
- Download the Android 6.0 ROM from Google Developer and flash it. That should fix all of your softwares problems. [https://dl.google.com/dl/android/aosp/hammerhead-mra58n-factory-aeca4139.tgz]
- To fix the charging issue, which I faced it too ! Use another charger which has the following details - 2.0A/5V (I use Samsung Tab Charger, charges real quick !! )
That's all !!

No Wi-Fi on Nexus 5 - on any version of Android

The Wi-Fi on my wife's unrooted Nexus 5 (Sprint version) which was upgraded (via OTA) to Marshmallow last month suddenly stopped working last week. The slider would get hung while moving from Off to On (like it was trying to turn on) and therefore was not detecting any available Wi-Fi signals.
After trying many things, I eventually did the extreme and did a full factory data reset. No dice. Still not detecting anything.
Figuring it might be an OS issue with Marshmallow (given we're seeing a lot of forums indicating Nexus 5 issues based on Wi-Fi with both Marshmallow and Lollipop), we downgraded the OS first to Lollipop and then all the way back to KitKat (4.4). Still not working. At initial phone setup, the phone is not detecting any available WiFi signals and gets hungup trying to find networks for me to choose from - so I end up having to skip this step.
Any other tips out there on what I can try? Is this a sure sign of hardware problems? Don't think my wife's phone is under warranty any longer (have had it slightly over a year, I think).
PS - Now I can no longer even upgrade the phone (OTA, at least) from 4.4.4 because my phone is saying it needs Wi-Fi to download the update - with no option to do it over my data plan.

I'm in the same situation and it appears to be a hardware failure. The wifi chip can't be replaced so a motherboard swap is required.
You can upgrade to the latest stock ROM by flashing the entire ROM from a command prompt in Win7.

Plot thickens
So, I figured out a way to get the OTA's over LTE (by manually changing my phone's date up a week). While going through each OS update from 4.4 KitKat to 6.0 Marshmallow (about 5 or 6 rounds of them) my phone briefly was able to detect WI-FI, I believe during set up at 5.1.1 Lollipop - and I was able to get on my home network.
Probably should have just stopped updating after that, but definitely was not detecting anything after that. I lost it during one of the Lollipop updates - well before getting to 6.0. Not sure if WiFi was actually working well or not.

Maybe the chip is in the process of failing? Not sure but it seems like you are having better luck than me.

I wish. Don't want to go through all those steps again after doing a clean wipe to have a fleeting glimpse of Wi-Fi.

Hi, pagalbengal. I'm having the same problems right now, and I wanted to check with you to see if there have been any developments with your situation over the past month. Still hopeless? Have you contacted Google tech support? Do they still even support this phone? Thanks for any info.

You guys might want to try reflash the modem firmware.

Couldn't get my wi-fi to work so I replaced the motherboard. Every stock and custom ROM I tried could not enable wi-fi.

WiFi disconnect when screen turn off

Hi guys, I have a little issues with my nexus. When I lock the device, the wifi turn off and reconnect as soon as unlock the device. I've started to have this issue 3 weeks ago, I've updated from stock android 6 to 6.0.1 and the problem are still there (I've tried using cm and 2 or 3 others roms too). I don't have any energy save app or samething like that, and the option in "advance wifi" is set in always on.
I'm trying to read the log but I don't understand where is the wifi problem.

Hi,
Have you tried restoring to the latest factory image https://developers.google.com/android/nexus/images with a full wipe?
(make sure to backup any data that you wish to keep before hand)

Yep, twice

This is a known issue that started with 6.0/Marshmallow.
It’s discussed in this thread.
Please to go the official Android Issue Tracker entry and star the item to vote for it. It’s already a high priority and been acknowledged by Google, but wasn’t fixed in 6.0.1. More exposure might help get it fixed sooner rather than later.
https://code.google.com/p/android/issues/detail?id=190667

I'm having this issue since I first used this phone (upgraded to Lollipop right away). It has been around before MM, but back then it felt I was the only one. I had given up.

Please turn off any battery saving applications or battery saver feature and then check again if the issue still occurs....

S7 with custom rom(s) and Xposed - Internet connected apps breaking

Hi all, long lurking rom-installer who can self-fix most problems here. Got a problem I can't fix that's bothering me. Recently upgraded to an S7 so naturally rooted it on day one and been trying to get it my-kind-of-working fully ever since. I do like to bugger about with things in a vain attempt to shield some private data from some orgs and realise I'm in a particularly specific hole that I'll probably have to climb out of on my own, but if you don't ask...
Internet using apps pretend to work, sometimes for days, then just refuse to open. Screenshot example of the second and persistent error (after simply "Lightning has stopped" the first time) is attached.
Model: G930F
Current ROM: ambasadii 7.0 TW Nougat (here)
Xposed: 88.2
Root: Magisk
Significant mods:
1) use xPrivacy
2) disabled significant number of remaining packages using Package Disabler Pro (list attached)
3) run Orbot
4) run AFWall
5) modify app permissions in Settings/Apps to restrict where I think I safely can
6) run BackgroundRestrictor
The behaviour still emerges even if I don't apply 4), 5) or 6), it has started prior to me finishing my tweaking.
I know xPrivacy is not supported for Nougat but it seems to work ok for the most part with some retweaking of settings since moving from Marshmallow on my old phone. I understand it could be the cause of the problem but I'm wedded to (some of) my privacy enough to persevere before abandoning it. For the record I've checked the usage log for restrictions on any calls around e.g. internet that might be interfering but I've been unusually generous with permissions trying to fix this and there's no restrictions on any apps with internet access around that, or much else really at this point. I've also had a look in general usage log rather than app specific, looking for system components that may be working alongside the app and failing with a restriction but can't see anything being denied. Any system apps haven't been touched by me, I fetched what I could from xprivacy crowdsourced restrictions on the base ROM apps and then only applied my template to apps I've downloaded myself.
Some other background on the problem: everything will be set up as I like it - ROM installed, debloated, all the rest of above modding applied. It will be working super-fine. Nice and fast, little bloat left, just enough Google to get Play Store, apps installed and working, all will be and appear fine. After an undetermined & fluctuating length of time all of the internet-facing apps will suddenly not open. This includes but isn't limited to the Browser (stock and Lightning, Brave, Pale Moon, etc.), Twitter, Signal and the Official TWRP App.
Interestingly, internet-connecting apps that will connect on demand but don't seem to make a call on every app open (mostly due to prior settings changes) do not fail. They will still open fine and work fine, connecting when asked and not crashing. For example, K9 Mail and Pocket.
Another weird data-point: Signal will fail but will often do so later than the other internet-connected apps - possibly it has a token with GCM or something that when it expires will try to renew on app open which is when it starts to fail like the others?
The apps will work again if uninstalled and reinstalled but once the behaviour starts again, and it will, it will repeat. Sometimes twice or more in a day. So reinstalling every time is not going to make for a usable phone. It's like they have an error renewing their wifi lease or something.
It can take up to three days to begin - this build it worked fine for days whilst I was away and slowly, progressively building the system back up with regular TWRP backups. I can restore a TWRP backup from about 6 hours before the problem started and it'll work fine again, but still wait a random amount of time before the problem begins again.
I did think it may be something to do with the router here and home WiFi as it behaved much better whilst away and didn't break until my return, though that is likely coincidence. I'm in pattern-observing mindframe so false positives are everywhere. I thought it was connecting to the PC via USB that was doing it at one point.
Last data point: it's happened with a different base rom too (Decent here), same thing, but came on sooner each time. I would change the base rom again to see if it's something there but I suspect that should be one of the last things I try given it's happened across two roms now.
Anyway, if anyone has any insight on Nougat TW ROMs on an S7 with this kind of set up and/or any clues or ideas as to why internet connects would suddenly be crashing all these apps... I'd be grateful. Otherwise I have many reinstalls and possibilities to eliminate. Which means waiting many sets of days before I can repeat, which makes progress frustratingly slow when you depend on the phone (Signal particularly) to connect with people.

AFWall stands out if you're having problem with net connections to apps etc

Yes good point, thank you. I think i've run the ROM with same problems without any rules applied but I've disabled it fully now just to be sure. Much obliged.

If it persists, the proper way of troubleshooting would be to clean install the ROM only, no tweaks, Xposed, firewalls or anything, just the ROM and your apps you're having problems with
If that all works together fine, then add ONE new thing to the mix, test for a few days, rinse and repeat until you add something that causes the problem again
With testing for a few days between each new addition you're be 100% sure what is causing it once it starts again

Thank you! Yes that's the plan but I thought I'd ask first as there's a lot of waiting down that route. I did do it to a point during last build but only waited overnight after each phase. I think I'll start that.now. I can always restore this backup if the solution presents in the meantime.

Yea that's what I was thinking, backup this ROM, clean install, work out the issue, restore this ROM and fix it
Good luck

Thank you I'll report back if/when I work it out, for any other possible future readers.

I changed the base ROM & installed Xposed in a different way and rooted in a different way and tweaked Permissions to be more permissive and and and... I've read rovo89's farewell so I won't say "It's xprivacy" but it's definitely how xposed & xprivacy interact, whether by flashable zip or systemless magisk. It'll work fine for a good while but then starts corrupting everything internet connecting. Removing it removes the problem & restores the app functionality.
Sadly it's the same even if you restrict nothing in xprivacy & just leave it installed & switched on. I've had to remove it. Considering trying to go back to MM as I know it worked on my previous phone.
