Well if I had hair on my head I'd be pulling it all out right now. Had this phone (US998) for over a month now and still can't get it to connect to the 2.4ghz interface on my router... (Linksys WRT1900AC running OpenWrt). It had this issue before I ever bootloader unlocked and rooted or modded in any way. It connects to 5ghz without issue. I'm able to connect to certain other 2.ghz routers but others it won't. I turned on verbose logging and when I connect to my router it says "Saved", then "Disabled" and then says "Network_Selection_Temporary_Disabled", "Network_Selection_Disabled_Association_Rejection". My other phones and devices connect fine to 2.4ghz. The list of things I've tried would be a mile long. I recorded a log cat while connecting to the network and have attached that. I see some errors and lines of interest in there under the various wifi sections and wpa_supplicant but can't make sense of them. I tried adding my AP into the wpa_supplicant.conf, I tried duplicating the settings in wpa_supplicant.conf in my other LG phone onto this phone. Tried various different settings in wcnss_qcom_config including setting band capability to 2.4 only, Phy Mode to auto, 11n, 11n only. Disabled 5ghz on my router then on 2.4ghz iface changed channels, channel width, SSID, password,tried different encryption & disabled encryption and set as Open, mac address, N and legacy mode, tx power, assigned a static lease to my phone trying differnt Ip's, disabled mac filtering and hide essid. On the phone i've tried static ip, third party connection manager app, wifi analyzers, network reset...and much more. I'm so frustrated and burnt out on trying to figure this out. I have the wpa_supplicant.conf file but I can't find wpa_supplicant in system/bin or anywhere else on my phone. I just don't get it, can't figure this out and really need your help. Thanks, Duh
I don't know what the exact cause of the problem was, but I upgraded my OpenWrt firmware and now my phone will connect to 2.4ghz. But my phone still won't do screen sharing even with my Lg phone and Lg Tv (LGUK6500 AiThinQ) both connected to 2.4ghz. Any Ideas?

Did you use any of the silly "debloating" guides? Someone else did and lost the ability to mirror to their LG TV.
My opinion it's silly, because we have found out with LG stock firmware many system apps are connected. By debloating what you think you don't need, later you do need or it causes lag -- because the system "looks" for it before moving on. Also the "packages" you are removing don't have clear labels as to what they do. Any guides written are NOT written by LG nor usually even Devs, but people who mean well but don't have access to LG database.
Better to "freeze" anything unwanted in Titanium Backup, than actually remove it.

No, it's been unable to do screen sharing even with a fresh install. When I did debloat I used the debloater magisk module and removed facebook apps, instagram, some games, and froze google photos and google movies

Hope someone can help with this: rooted the other day using the htc unlocker method. so s-on with root and still stock rom..have not changed anything other than install busybox. no other changes. have not even gotten to flashing roms yet. So the phone will not recognize my home towifi. when it scans for networks, it sees everybody (neighbors) but mine as being in range (even tho i am sitting next to it). at one point i finally got it to connect yesterday, but then when i went to work it never disconnected and returned to 3g, so when i went to use my internet for something it said it was still connected, when in fact it wasn't. so no data and no 3g. I had to physically turn off wifi to get the phone to be able to connect to 3g. now i am back home, it will not connect again. the phone does not see my network as being "in range", therefore will not connect.
I have several other devices that connect to the network just fine (like my laptop I am typing on).
any ideas would be greatly appreciated.
There's an app called WiFi analyzer and WiFi manager available on the play store. Idk y it isn't connecting to your WiFi now when it did before, but maybe one of these 2 apps can help.
WiFi analyzer will tell u what channels thw other WiFi networks are on in your area. It could be an issue of interference. It will also tell u the best channel to put your WiFi on to avoid that interference.
Do u have best WiFi performance on in settings-WiFi? Turn it off/on see if it makes a difference. Off is optimal since it kills batteries.
WiFi manager helped my phone recognize and connect to open networks quicker than stock settings did. Maybe try that as well.
Is your connection password secured? WPA/WPA2, WPK? Is it a linksys router? Try making a static ip for your phone. My phone would never connect at work on an open network until I made it a static ip. Or it would connect and never send data.
Actually, try that first, I forgot about that. If its an older linksys router that's probably what it is.

I will try some of those things, but I don't think that is it. whatever is wrong is coming from root. everything was fine before that. and i don't know anything about setting up a static ip. not a linksys, btw.

Root doesn't have anything to do with your WiFi. It is highly unlikely anyways. Google how to set up static ip. U can do it right from your phone.
Your router doesn't show up at all or does is try to connect and nothing? Mine tried to connect and nothing. To set up a static ip your phone needs to at least see the router.
If you're rooted are u s-off? Either way, try installing a rom of your choice and doing a full wipe to clear out whatever is causing the issue. Maybe try installing new radios/firmware. RUU to newest ota version.
Good luck!

downloaded wifi analyzer, but that doesn't really help me figure out why the wifi will not connect or disconnect properly. As stated in my original post I am rooted, s-on, with unlocked bootloader htc method. this problem is almost exactly the same problem i had my samsung s2 when it first came out. the radio would not wake up after sleeping and the wifi radio was all messed up. In exactly the same way..
once it connects it is ok, but when i leave the house it never disconnects! so when i go out, it does not switch over to the 3g radio, and at that point i have to TURN OFF wifi. When I come back in the house then i have to go through another long process of trying to get it to connect to my wifi again. I did not change ANYTHING after rooting. So it has got to be related to that somehow....it just says. "MWOI0 not in range", but yet it will show 5 others in the neighborhood as being available (all secured like mine).
Does your regular computer/laptop connect to your wifi?
Have you rebooted your router/modem?
We had a power outage/surge one day and the computers connected still had connection, but the items which were disconected (phones left house for work) would not reconnect.
I know it sounds simple, but we spent half an hour figuring out why some devices had wifi and some didn't.
You are seeing neighbors wifi's, that's why I suggest this.
I also noticed this other thread, maybe related,
http://forum.xda-developers.com/showthread.php?t=1691189
There's an app called tasker in play store that allows u to turn on/off wifi by location automatically. It costs a pretty penny, but definitely worth it. The possibilities are exponential with that app.
Look into setting a static ip & change the channel on your router. Give u advice and u don't want to try it. Do u really want it fixed or is it just an annoyance u like to complain about?
Static ip worked for my phone in a similar situation. Up to u to implement the fixes.
I have an Asus Slider Sl101. Around 3 days ago, our router had been changes as the previous one wasn't working properly. Our carrier is Charter and our router is Netgear. We hooked every device up to that new router and everything worked fine, including the tablet. But later on in the day,the Internet on there stopped working.
It shows that it's connected, but when I try to access the internet through the browser, it does not work. The blue line at the top of the browser starts up, moves forward a little, and stops entirely while the browser then says "Webpage Not Available". Apps that require Internet, such as Accuweather and my SAT apps, fail to work as well. Other devices that use our wifi include another computer and Nintendo DSi and 3DS. They all work fine. Our router shows that our android is connected to it, as well.
I've tried the static IP stuff, restarted the router, left the wifi off on the tablet for a few hours, and turned it off and off. I even factory resetted it and not even that helped.
I apologize in advance if I haven't given enough information; that's as much as I know save for whatever I can include from the tablet (IP Address and such).
Try changing encryption method

It can be modified from the admin panel of your router. Obviously, each connected device must be upgraded to the new encryption method.
However, you can simply do a test and see if the connection works

Oh! Under "security", it says "WPA/WPA2 PSK". I believe it has always said that, even with our old router.

Probably
If the problem is not of the device, many network problems are usually caused by encryption or are due to the channel where the router works. Both settings are settable in the admin panel.
Try changing these.. Remember to make a backup first!

The things is, though, my tablet was working when we changed the router. Ever since then, nothing has changed when it comes to settings and all. Every other mobile device is working well and the computer out front that uses wifi works well.
In your eyes, the router seems to be the main problem, right? Do you think if we call our internet provider--Charter-- and ask for a new one that it might be able to work as it will be new and all? Or will it most likely not help too much?

hi sir i have already hack wifi paasword but not connected
password is correct sometime before i have connect
Is the router 2.4 or 5ghz, and is the tablet the same?
So I recently moved and had to hard reset my router (Netgear WNDR3700v4) due to forgetting my admin password. After I reset the router and got all the WiFi settings the way I like them my room mate and I started having trouble with our apps on the WiFi but no problems on 4G. He has an HTC One I have the Optimus G and we were both experiencing the same problems. So here is the story of how I figured out what was bothering the phones:
First we noticed the problem on Facebook and Youtube. Nothing would load as pictures and media but text came up fine. I tried re-installing the apps, no difference. Then I tried re-installing my ROM (SlimKat latest stable) no changes. So I did what any well versed IT would do and began my hunt on Google. I found very little to nothing, mostly people blaming routers or ISP's. That would simply not do. After carefully combing through my logs and comparing the WiFi data traffic on my PC's, game consoles, etc. It seems it was only our phones that had this problem. So I put my network engineer hat on and started tinkering with the routers settings. One forum thread suggested it might be a DNS problem. I figured that TimeWarner is such a garbage ISP the DNS servers were bound to suck. Well I tried OpenDNS and GoogleDNS ip's and there was once again no change. Now I was about to head-desk when I clicked on my routers advanced WAN settings tab, and there was the culprit. In the case of my router it has an option for the IPv6 to be DNS, 4to6, off, etc... In this case the solution was to disable it entirely. Sucks. It looks like KitKat has a problem with some routers IPv6 where a bit of data makes it to the phone and then the data stops. Any DEV's out here know of a fix for the IPv6? Anyone else have this problem? Everything runs great now that I'm back on IPv4.
TL;DR Try turning off IPv6 on your router.

Hey everyone, I wanted to put together a thread focusing on wifi issues of different variety and what we can do to potentially fix or workaround the main issues
I personally have been working on a solution for the discrepancy that disallows me to connect to my enterprise wifi at work, lollipop and previous versions connect just fine. So far ive found this issue. May not be easiest nor even possible for some of the issues some of us are having, but i think its worth working towards solutions.

What wifi issues? You might need nrw router.
I was able to connect via guest, then they had lock it due to bandwidth consumption. I have password since im a supervisor and my other phone (5.1.1) connects just fine. The nexus says saved, but when i click connect nothing, doesnt say obtaining ip or authenticating. Credentials are correct and connected before to same network without lock

Does your nexus connect fine to other wireless networks? How can you blame it on the device instead of going and fixing your work network settings instead? There are no wifi issues. Call an IT guy and he will fix your router.

Interesting, I just read through a lot (more than I can believe) of that issue log. It sounds like its technically not a Google/Android 6.0 problem even though the problem arose with the upgrade to 6.0. Have you considered doing what Nick suggested and reaching out to your enterprise IT administrators at work to see if they can or plan to do the necessary updates?

Yeah it connects to others but all devices lollipop and older including iphone and blackberry connect fine. And its known that android m has issues connecting to some wifi that works fine with all other devices. If you do a quick search youll see basically all 6.0 devices (nexus 6, etc) have same issues once updated to 6.0 (hit or miss depends on network they try to connect to, but same story just fine before update). The IT dept are not going to change settings on their network that works fine with 99.9% devices that people have there, since im only one so far with a 6.0 device (IT request MAC address when you get pass) it obviously is some sort of security policy within the os or something of that nature

Yeah, they are hesitant to change what works for almost everyone that connects to it. Also i think itd be a good thing to work on since most IT admin wont change for the very few with newer devices
On a side note i do feel like its more or less a cop out of them to claim its not 6.0 fault because when push comes to shove it works fine but once 6.0 it doesn't and nothing changed on the network
When I had my Nexus 5X, I had issues connecting to WiFi at home until I used the Network Settings Reset option under Settings > Backup and Reset. I think this issue came from the restore of settings during initial setup. Possibly worth a try.
Still, the issue I'm running into now is that my 6P only connects to one of the two routers at home. I have both broadcasting the same SSID though they're different brands and one's an older G router. On my Moto X running 5.1, the phone would connect to the strongest signal. Seems the 6P will only connect to one and never connect to the other. I've had the phone "forget" that one and connected to the other and then it refused to connect to the original. Very odd.
My point in saying this is that I wonder if there's a similar issue occurring in the OP's office. Though the same SSID is being broadcast, its as if the phone remembers the MAC address of the specific router it originally connected to and refuses to connect to any others. Just a thought.

I'm also having WiFi connection issues with eduroam (an often used protocol in UK universities) amongst other including my home dual band ac network. It locks out and can only be resolved by a reboot, which then takes 30-60 seconds to power off. Not normal or 'just an admin' issue. It seems to be software related as it is not constant nor predictable (ie it's not in certain areas and a reboot always reconnects). I'm unconvinced by the 'speak to your network admin' argument as it is neither useful or realistic and incompatible on my current patterns of usage or the issues being reported more widely.
My 6p works fine on my wi-fi router at home, but when I go over to my son's house, I have to go into Advanced Wi-Fi options and change the frequency band from automatic to 2.4 GHz only. Then I have to cycle my wi-fi off and back on. Then it will work on his router. Otherwise, it with keep trying to connect and fail every time.

Yeah, these are the issues (including the issue im having) that im talking about. Theres clearly issues with wifi on 6.0. Its not an issue with the hardware, nor is the solution "buy a new router" or "must be the settings on your companys network" granted most people can connect everywhere they've tried but if they tried where we cant connect or have issues they'd have same problem. Im thinking its a problem due to security policies or something along those lines but we should be able to alter, remove, or opt out of them at our own risk. Just thinking out loud.

Hi guys,
so this is kind of a last resort... I asked and looked everywhere trying to figure this out. There are certain WIFIs that my v30 (H930, v21o, stock rom with magisk) just won't connect to. For example at my work wifi. Or recently I got it with a wifi at a McDonalds.
-->When I try to connect to it, it first says "connecting..." but only for a very short instant, then it switches to "saved" and finally after another ~30sec it finally states "disabled" and then it stays there without ever connecting.
I have talked to the IT guy and he never even gets an attempt to log in from my phones MAC adress, so there is no connection attempt made by the phone... We did router restarts, tweaked some settings... nothing. I tried resetting my network settings, updated firmwares...
Otherwise wifi works perfectly fine at home and at friends places with both 2.4ghz and 5ghz..
Any ideas?

Do you have any custom DNS settings? One guy found out his work Wi-Fi network was rejecting his phone when using Cloudflare DNS.
How he figured that out, I don't know. But changed DNS server to another and he connected.

Not true. Various ad blocker apps like Blokada and AdGuard change DNS servers. In AdGuard settings as well as Blokada you choose what DNS servers you want to use.
I'm not saying that's the reason you can't connect to Wi-Fi, but apparently some Wi-Fi networks don't like Cloudfire and there may be others they don't like. Are you using an ad blocker?
To answer your PM, I'm using rooted stock Oreo US998 20h. My wife, mother, sister and brother-in-law are using full stock Oreo US998 20h.

I only use the DNS app from Cloudfare. And it cannot work without the phone being connected to the Internet.

Uhmm... do you have a SIM card? An active cell phone plan? Then you are connected to the Internet already. The problem you are having is connecting to a Wi-Fi network for your Internet connection instead of using mobile data.
I'm pretty sure the Cloudflare app works whether you use cellular internet or Wi-Fi internet. Otherwise it would be useless half the time.
If you don't have an active cell phone plan with data and are ONLY using Wi-Fi to connect to the Internet, your DNS settings are still being set by the Cloudflare app.
Your problem may be something completely different. I was just mentioning Cloudflare DNS settings as something I was aware of but most people aren't. Then it's striking that you indeed are using Cloudflare...

Uhmm... do you have a SIM card? An active cell phone plan? Then you are connected to the Internet already. The problem you are having is connecting to a Wi-Fi network for your Internet connection instead of using mobile data.

Maybe it really is the problem.
I don't use a SIM card in this phone.
I'll try uninstalling the Cloudflare app tomorrow to see if it works, since that access point is in the house of my friend.
But why are they preventing us to use custom DNS, though?

Assuming that's what the problem is, various reason. The guy that couldn't connect to his work Wi-Fi probably has corporate IT department that wants to log all DSN queries (Big Brother).
Some ISPs in the U.S. make you rent their cable modem/Wi-Fi gateway rather than provide your own. (Congress has now passed a law forbidding this but doesn't take effect for another month or two.) Anyway on those ISP owned gateways they control all the settings, including possibly blocking custom DNS servers.
For others just may be issues with Cloudflare 1.1.1.1, whereas Google's 8.8.8.8 may work just fine?
To test, you may want to install a DNS Changer app where you can change to DIFFERENT DNS servers of your choice.

Thank you for sharing the app.
I notice that this problem occurs after I Refurblish the phone with Us998 20h via LGUP.
Today I flashed the Nougat Us998 10d in Partition mode (LGUP), factory reset with hard buttons, then flash Oreo US998 20h in Upgrade mode (LGUP).
After done setting up everything, I can connect to that access point.
I installed the Cloudflare app, turn it on with wifi on, and then turn the app and wifi off.
I could still connect to that access point.
So I think the problem wasn't the Cloudflare app.
I think the Firmware us998 20h must be missing something. (The downloaded firmware file's md5 code is exactly the same with the md5 code in the thread about us99820h kdz).

Interesting. That's about the opposite of what I would have expected. Refurbish rebuilds from the ground up, like a super duper factory reset.
If you had bootloader unlock and TWRP custom recovery and told me you updated to Oreo 20h using TWRP flashable zips and didn't have everything -- that would be understandable. Those are incremental updates, which is why you have to flash the 20e, 20f, 20g, 20h zips all back to back to get "everything" in the 20h KDZ.
But telling me you flashed 20h KDZ (which is an LG official FULL stock image) via LGUP Refurbish mode and somehow it's incomplete vs "Upgrade" mode via LGUP (which only adds parts you don't already have) is very strange.
However, I'm glad it's working for you now. I'm just very puzzled.
Just wanted to report back, since Pie update all my WiFi connecting issues went away. It was clearly an issue with the firmware I used back then and something they fixed with Android 9.
