Lost LTE and internet access on some Wi-Fi networks after flashing Cyanogenmod - Verizon HTC One (M8)

This is the first help post for anything tech-related that I've ever posted- I'm usually good enough with Google to fix my own problems, but this one has me flustered.
Until yesterday I was running DigitalHigh's GPE ROM but decided to give Cyanogenmod another try after some persistent lag issues. Everything went fine during the install until I noticed that I was stuck on 3G no matter what I did- airplane mode, reboot, clear the cache, try to update APN settings, etc., nothing helped. Additionally, while the phone will connect to my home wireless network, it has a ! next to the connection symbol despite my being able to use the network with my laptop. The funny thing is, this only happens with some networks. Neither my home network nor the network at work will give me internet access, but if I plug an ethernet cable into my laptop and create an access point that way, I'm fine.
Here's what I've tried so far after scouring these and other forums:
-Reverted back to the previous ROM
-Flashed new firmware
-Flashed two new kernels
-Tried every different APN setting I can think of
-Popped out my sim card, waited a bit, and popped it back in
-Rebooted countless times
-Cleared every cache I can think of
-updated TWRP
There's probably more that I can't think of off the top of my head as well. Does anybody have any idea what on earth has happened to my phone?

[Q] [AT&T] Wifi from hell, help?

So, before rooting, my One X had great Wifi connection. No issues. Now that I'm rooted, I can't connect to wifi to save my life. I tried the wifi fix (not the ROM, but the 3 files instead) and still nothing.
I've tried turning off Mobile Network while wifi was on, turning mobile network on while wifi was on, tried restarting the wifi....
I cannot get a connection to the Store, browsers won't open webpages, it's essentially done for. Yet every other device in my house can access the router just fine (and it's not just here, it's elsewhere.)
Anyone have any ideas how to fix this short of flashing the new ROM (which I can't do from my house since the HTC drivers always fail to install.)
Have you tried running fix permissions to see if there's some sort of error holding things up? The only other thing I could think to do is to do a factory restore of the phone, unfortunately...

Another Wifi Problem P6210 (SOLVED)

Two days ago, my device suddenly could not connect to any wifi anywhere, encrypted or not, WEP nor WPA. This began to happen after I did a backup though CWM.
It sees networks but continuously runs through a scanning, connect, disconnect, scanning cycle. It tries to set the IP from the network, but then flashes unsuccessful and starts scanning again and repeats the process, and in the list of available networks, all available networks cycle between being not in range, remembered or disabled.
Sometimes wifi networks are greyed out, sometimes, not. Sometimes it cannot even find my router, even if I place the Tab on top of it. It connects once in a while, randomly, but only holds the connection for a few minutes.
I have other wifi tablets and all can connect to my wifi, nothing has changed with my wifi settings, router, etc. But to make sure, I did cycle the modem and router on and off and even reset the Airport Extreme that I use to factory settings. Modem is new and Airport Extreme is only a couple of months old.
My Tab is rooted and running stock HC. Never been dropped, great condition, never exposed to shocks, water, etc.
I have tried the following fixes:
Restored to factory settings, wipe data, etc. Nothing. I have tried this several times.
I have tried setting a static IP address. Nope.
ODINed it back to stock using P6210XARKL1_P6210UEKL1_HOME.tar.md5. It briefly connects to wifi long enough to apply the update and after that, it starts cycling scanning, connecting, disconnecting, etc. Tried this several times as well.
I even tried the update to the UK ICS for the P6210 and have the same problem. It sees wifi, but cannot connect, and on occasion it cannot see any wifi at all, even when I am 2 feet away from the router.
At this point I am convinced that it is a hardware issue (either that or it is pouting because there is a new Nexus 7 in the house)
Anyone have any other suggestions for a fix?
Update:
I did another hard reset from within Settings-->Storage--> Factory Data Reset, rather than through recovery (either stock recovery or CWM) as I had done before.
Now, wifi connects a little more consistently. Would resetting that way actually make a difference? Or is this just a random thing? Am I trying to see a logic where none exists?
How would a hard reset through the system settings be any different than one through recovery? Or, does each reset clear something else that got corrupted along the way?
My wifi still randomly cycles through scanning, connecting, disconnected, just as before. However, now the connection is actually made more quickly (under a minute when before it could take up to 15 minutes - or just never connect) and seems to remain connected for longer periods of time now.
Well, after searching and reading through 100s of similar issues one of the workarounds is to use a wifi widget or a WiFi Fixer App.
I am using a widget to control wifi and it along with any other random thing I might try can occasionally make my Tab connect to my Wifi network.

Persistence = Profit.
I think I have finally solved the broken wifi issue. Just to recap, the problem started after I did a backup with garyd9's CWM http://forum.xda-developers.com/showthread.php?t=1379532.
And as a last ditch effort I even tried toggling the wifi on/off with a widget as was suggested from other sources (Google is your friend), in addition to factory restores, or restoring from a CWM backup, etc. And that was not a reliable solution after all.
These are the steps I took.
Through stock recovery, I wiped data and cache, and did a factory restore, twice.
I ODINed back to stock, again.
Wiped data and cache and did a factory restore.
Wifi was still sluggish to connect, but finally I was able to load the update.
Then I wiped data and cache and did a factory restore again.
It has been 24 hours and I still have a strong wifi connection. If I power my Tab off and wait an hour or two, then reboot it connects immediately to wifi. If I toggle wifi on/off it still makes an immediate connection. YAY!
So, it seems that something got corrupted during the initial CWM backup and then persisted through many wipes and reinstalls.
UPDATE:
Still have working wifi!
I'm having the same problem now. I'm using latest CM9.
I was using Google Chrome just fine when suddenly Wifi disconnected for no apparent reason and it's now showing the same symptoms you described in the first post. I have formatted cache and cleared dalvik cache and it didn't work. Wiped everything and it didn't work. Reflashed CM9 and tried two different Wifi fix flashable ZIPs but I still got the problem. I'm wiping everything and reflashing CM9 once again.
Is someone else experiencing this?
I'm afraid to data wipe in stock recovery due to the brick bug reported (my tab uses one of the defective chips).
How is your Wifi holding up, VitaZora?
I hope persistance pays off.

My Tab also has the defective chip, but I didn't know that until AFTER I went through all those wipes and reinstalls.
But I can report that all is well and wifi is still working like a charm.

Ohhh I see...
I did wipe in HC stock recovery several times, but not in ICS stock recovery.
Have you wiped in ICS stock recovery? By selecting "Factory default" option from config menu or by manually going to recovery and selecting data wipe? Or both? Hahaha
Thank you for the reply!

Honestly, I can't remember. I know I flashed ICS twice as well as the CM9 version for our Tab.
I think the order for flashing from rooted HC was the following:
ICS, CM9, HC, HC, HC, ICS, HC.
In between each was either factory restore from the config menu or through recovery. Occasionally after flashing my device back to stock, it would go into a reboot loop and the only way to fix that was to enter recovery and wipe everything. But I reflashed so many times and tried wiping and factory restores multiple times as well, that I may have wiped ICS through recovery - in fact I am sure I did at least once.
Oh well, I guess I live dangerously.

WiFi does not reconnect (Android Issue #58230)

EDIT BELOW:
Hey y'all, I recently got a Nexus 5 and I've been having issues with WiFi reception. I've read the other threads concerning the inability to connect, but I can easily connect to a wireless router the first time.
It's when I disconnect from one specific router and try to access another one that I run into issues. It simply hangs in Connecting, and then just reverts to Saved. The only way for the phone to connect to a router is for me to reboot it, in which case it does so quickly.
I was wondering if anyone had any insight into tackling this problem, or if it's an inherent software issue. This occurs both at home and at school, where I move from building to building (switch routers), but the login credentials are the same.
Thanks!
EDIT #2: I spoke to a Google rep a second time and they decided that since my factory reset did not fix the issue, they were sending me a replacement unit. I'll update this when I get the new unit and see if it still has the WiFi issue or not.
EDIT:So this issue seems to have garnered some attention in the 4.3 release of Android, and a handful of Nexus 5 owners have already reported the same issue (myself included)
https://code.google.com/p/android/issues/detail?id=58230
(Sorry, I can't post outside links because I'm a new user)
So if you have a similar problem, feel free to star and add your own comments.
I happened to have the same problem......not sure if this is a hardware problem or not.

Ah, I see. Well, I've narrowed the process to simply toggling the WiFi on and off, rather than having to reboot the phone. It's still occurring though.
If I manually disconnect and then reconnect to a router however, this problem doesn't seem to happen. It's only when I exit a router's range that I have to do a WiFi on and off cycle.
Sent from my Nexus 5 using xda app-developers app
Oh, and I notice that the perceived signal strength drops when I try to reconnect to my router. Again, toggling the WiFi on and off allows the Nexus 5 to immediately connect to the router.
I hope this is a software issue.

Hm..Toggling wifi on and off doesn't seem to work for me...It hangs in connecting for a few seconds and then goes back to saved... I still have to turn off/on the phone before it can connect to a different wifi hotspot..
I've got the same problem: switching wifi networks, from home to work and viceversa, my N5 doesn't connect. It needs a reboot.
Ciao.
I edited my original post with a link to the AOSP issue tracker concerning this problem. I also contacted Google concerning this and they just said to do a factory reset... To no avail.

This evening, before entering home, I switch off WiFi, then I toogled airplane mode, I toogled WiFi on, and I got connection perfectly working.
Sent from my Nexus 5 using xda app-developers app
Interestingly, when first resetting the phone, I had to toggle Airplane mode in order to reconnect. However, eventually I can just toggle WiFi and it works fine. I'm not sure where the change occurred, unfortunately.
Hopefully my replacement phone doesn't exhibit this issue. Will update this, as mentioned in the initial post, when I get it. I still think it's a software problem, however, since folks that had 4.2 and updated to 4.3 suddenly experienced this issue.
So I'm starting to have this EXACT problem myself. I have a very strong signal for my home wifi and it's basically dropping to poor when I try to connect. After displaying Connecting/Saved several times, it still fails to work. I have tried rebooting it several times, toggling wifi and airplane mode, to no avail. Funny thing is, my work and home wifi have been working perfectly prior to this.
It wasn't until tonight that I started to have any problems. I moved some files through USB, just some stuff from my nexus 4, rebooted about 15 minutes later, and I couldn't get wifi after the reboot. Weird.
EDIT: I've tried a plain factory reset, didn't work. I ended up flashing the factory image, still didn't work. I'm not sure how WiFi just STOPPED working for me. Contemplating an RMA... I really hope someone comes up with something, seeing as I have a perfect screen and none of the other defects listed before.
This may be a fix!
Hey guys, so I've been keeping up with two AOSP issue trackers
https://code.google.com/p/android/issues/detail?id=58230
https://code.google.com/p/android/issues/detail?id=61945
And in the second link (Issue #61945), scroll down to post #9 Ryan, and he details what he's tried in terms of doing a factory reset WITHOUT having Google automatically restore data and settings. I've documented my results trying this, and it seems (at this early stage of my testing) rather promising.
Like Ryan said, it seems like it's restoring some WiFi settings that may not play well with 4.4 (and maybe even 4.3 for those exhibiting this issue as detailed in the first link (issue #58230))
So here's what I did so that Google would not restore the WiFi settings. Unfortunately, this does mean you may have to manually reinstall your apps and re-input your data by hand.
What I did:
1. Go to Backup & reset
2. UNCHECK "Back up my data" and "Automatic restore"
3. Perform Factory reset
4. After resetting and prompted to do so, input WiFi router credentials to connect to WiFi
5. Skipped logging into existing Google account
6. Skipped making a new Google account
7. After reaching Android homescreen, I manually added my existing Google account
I have a feeling that steps 5-7 are unnecessary, but I did that just to make sure it wouldn't try to restore any of the data.
It's been working so far, but I haven't been able to test it out much since I'm a school currently and it has blanket WiFi coverage (difficult to go out of range). However, I will add that the signal seems stronger than before, AND it's more difficult to lose WiFi signal now than before. Like, nearly impossible here.
Let me know how it goes for y'all. Hope this works.
Oh, and perhaps try
https://play.google.com/store/apps/details?id=com.brilliapps.wifiandmorefixer
before you do the factory reset. It may or may not work (one person said it did). I haven't tried it though, but if it works, it'll save you the trouble of having to do a factory reset.

i have gone as far as complete factory reset
fresh install
not connection to google at all
so no previous settings
no sim card
nothing
just android 4.4 stock and a wifi connection
the issue still exists
5ghz seems to work fine but 2.4 connects/disconnects like a yoyo even though the connection strength is at full

I'm having the same problem, my connection is strong, but I can not reconnect to any network ... this is really annoying. I need you to help me with something: is there any way to eliminate all current wifi settings without making a factory reset?
I will wait for a fix until december, if not, I will send my phone to rma...
I ended up going with the bricked kernel and this issue has disappeared (at least for now). Been stable without any signal drops or wifi reconnect issues for solid 2 days. It is a record!

I have also seen this on my device that I just received on the 15th. The wifi seems to drop out and re-connect after a while... But, my other, older android devices do not show this issue. After reviewing the previous post about NOT restoring from google.. and creating a fresh install.. I am beginning to suspect if that was the case. I was hoping that keeping it stock and not messing around with kernels and roms was one of the best features of a nexus device. I really hope google provides an update to fix this.
So just a quick update. I didn't restore from Google on my second device and the WiFi had been fine for close to a week now.

I have the exact same problem. VERY frustrating. No idea what happened.
[Q] Stuck on WiFi Turning on
Hello,
I've seen this issue with various phones and various fixes... But I don't want to Hi-Jack anyone or anything. Anyway, I tried the dev build of "L" at one point... and my WiFi randomly stopped working. I thought "welp, it's a dev build... not gonna sweat it" and went back to stock 4.4.4... flashed back to factory, no dice. It seemed to turn on long enough during the setup process to "connect" but it disappeared when I rebooted to go to ART. Thought, welp, no experimental anything. Flashed back to factory, no WiFi. Not even during setup. Tried the various things I've seen around... obviously various factory resets, tried rooting and renaming wpa_supplicant.conf, flashed paranoid android because someone said that's the only thing that worked... it didn't. I do notice the kernel seems to be the same for PA and 4.4.4, so I could try another kernel, but have no idea which to try. After I put TWRP on, I cleared every cache, etc I could. Flashed back to stock after clearing system and no dice, tried running wifi fixer, tried installing macman... nothing. I did see someone say if the phone gets too hot, the WiFi chipset can come off, but the WiFi chip-set is the same as Bluetooth, and that's having no problems. I appreciate any suggestions, I really want this to work out. Otherwise I have a year with a phone with no WiFi... To kind of clarify (re-reading, I see I wasn't too clear about the actual problem), the WiFi toggle switch is set to "Off" and where your networks would display it shows "Turning on WiFi". This isn't just one network acting up, and this has been going on for a couple of weeks.
Edited to add: when I unlocked the bootloader today, the setup process showed me my networks but settings froze when I put the password in... so the hardware seems to be connected...

[Q] Strange Wifi/Mobile Data Issue

Ok so I have two of the universal Moto G LTE . We were running the unofficial cyanogen 11 perfectly for afew months and on one phone became unable to connect to our home wifi, shortly afterwards the other had the same issue. Flashed a LP rom but wasn't suited to the stability of it atm so settled on Slim-peregrine-4.4.4.build.9.0-OFFICIAL-8310 with Slim-Addons-full_gapps.4.4.4.build.9-20150107, and the issue was gone. However on the other phone after a wipe and clean install of the same rom and gapps the issue persisted and further would not connect to the wifi or it mobile data though still has perfect signal for calls and mms.
I'm no tech wizard but I have tried the following;
PHONE BASED
Flashed every kernel and every rom in the Moto G LTE forums (Yes ALL but not every combination)
Tried variations on the airplane mode
Fastboot erase modems1&2
Reverted to stock RETUS_XT1045_4.4.3_KXB21.14-L1.23-4_cid9_CFC.xml.zip via manual mfastboot cmnds & MotoFlash
Changed filesystems
Connected via direct IP (still no internet though it says connected)
ROUTER BASED
Reset it (Duh)
Tried a different router
Enabled/Disabled MAC Filtering
Once I realized the mobile data was out to though stopped messing with the router.
Currently it is running the above mentioned SlimKat and works wonderfully except no mobile data even with the correct APN info and fails to authenticate wifi. I'm at a loss, did the phones ethernet chip or w/e it is die maybe?
I'll provide any logs asked for if I can get them... It's my wife's phone that is having the problem meaning I really need to fix this or suck it up and buy a new one. Appreciate any help in advance and if not I understand, thats the game when messin with this stuff as a novice.
As an update, upon the monthly renewal of the data mobile data is still working. Just the WiFi is still not working.
