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?
Have you found a way to solve this problem?

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.

I'm having this issue with US99820H. There are some access points that the phone refuses to connect to.
It shows "Connecting...", and then "Saved", then "Disabled".
The phone is in Stock Oreo so there is no way to setting a custom DNS when the phone is not online.

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.

Thanks for the information!
I only use the DNS app from Cloudfare. And it cannot work without the phone being connected to the Internet.
I did tried to Force stop the app but still cannot connect to the access point.

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...

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.

does this work for anyone? i have never been able to on my 101
I have no problems connecting to my unsecured network at home (don't worry, there's only maybe five houses on my street that could even reach it!) How far can you get in connecting? For example, will it see the network when you scan? Will it fail when you try to select it? Will it select, but not have a web connection?

Never had a single issue. Are you sure it's not Adhoc or something? What channel is the AP?
i've been unable since i first bought it... and ive updated firmware and done full restores before.
it connects fine but doesn't actually have internet once it does. happened on a few different networks but most notably would be my phone when i made it a hotspot it would work fine if i put a password on but wont if i do it unsecured

I have to reconnect to my phone sometimes when using hotspot, seems like the routing breaks every once in a while, but I connect to multiple unsecured networks(actually using radius auth, but that won't change anything) on a regular basis. Sorry, I can't really think of anything that would cause that even after reformatting. I'd start looking at the dmesg logs for an error.
I have tried few different 3rd party vpn programs and they all yields the same result, always disconnects after 30 seconds or so, especially when data is being used.
I read that could be Verizon, phone specifics, openvpn, vpn program, and or android kitkat.
I had the issue on stock root rom and Jasmine rom.
Is there any way to fix this?
I'm using the non LG vpn. pptp. my vpn works fine on jasmine 3.0. I know it's not secure but I'm not doing any banking transactions or anything.
perhaps you could give more info as what your connecting with and connecting to, and what protocol.

I just use the default protocols and settings that comes with the app. Lets say Cyberghost vpn app. It would say connected, I open Firefox, go (any websites), in less then 30 secs it would disconnect and would try to reconnect.

Been an issue for years. It happens on almost every phone with every VPN app when using Verizon 4g. It has something to do with the way data is passed through Verizon 4g. There is some kind of firewall causing it used by Verizon. I read you can fix it by paying Verizon a buttload of cash for a static IP. Other than that, there is no fix.
And it's not like they want you using one anyway since they track what you visit on their network and sell that information.
I'm on the Jasmine ROM and even stock I used the LG VPN to connect and it works.
I can stay connected all day with no issues.

I had a s3 with Verizon and never had an issue with VPN disconnecting like with the g3. I do not know being on 4.3 on the s3 and 4.4.2 on the g3 has anything to do with it.

Any simple ways to bypass the security lock screen requirement?
I decided to try it and could not get it to connect with the VPN service I am using on my desktop.
VPN worked perfectly find for me on my note 2 that was on 4.3.
I know there is an issue with 4.4.2 because my note 2 on 4.4.2 didn't work either.
Anybody have anymore leads? I am aware that the stock VPN may work, but it does not have the options of the VPN apps (I need to configure each individual profile/site).
Tab S3 worked well on 7.x. Lost wifi completely address 8.0 update. Tried all the recommended forget connection, reset network, full wipe after ota . When all that failed I flashed the full 8.0 with Odin. Still had no wifi. Repeated all those reset steps again with no joy.
Strange part is the same situation occurred with my LG V30. Worked well on 7.x, no more wifi after ota to 8.0. Repeated the resets and full flash series again but still won't connect.
My Razer Phone and One Plus 6 phones connected to the same wifi out of the box (with 8.0?), ota'd to 8.1 and have been solid since.
Am I stuck waiting for Tab 3 / V30 flashable (stock) files to 8.1?
You can download some network tools from the play store. See if they help you pinpoint what is going on. You don't happen to have MAC address filtering turned on the router? Though doubt your MAC address would change but I did read an article where Apple changed the MAC Address in their iPhones after it was discovered the government tracked people by MAC address. So it is possible it changed. See if you can hit a public WiFi (library, coffee shop, etc) and get it to connect there? Or a neighbor's network?

Just set the hotspot on one of the working devices and see if you can connect to it.
Is the wifi actually enabled?
I had the same problem happened to my Tab S3 a few days ago after I upgraded to Oreo (8.0) I could connect to WIFI but it says I have no internet connection. I have tried different routers and at different places and still the same problem. Strangely, I can connect to internet from time to time (intermittently) despite my Tab S3 giving an exclamation mark on the WIFI signal and warned me I have no internet access. I have tried resetting network, factory reset no less than 5 times, and also tried connecting at different places. I have read somewhere that by changing the time on the unit fixed the problem for quite some people, but didn't work for me. I did not root my tablet, so now I'm stuck looking for solutions.
update 2018.12.05: there was a new patch out (Oct. 2018), so I updated my S3 and now it still doesn't see internet even after connecting to WIFI. I tried resetting and now I can't even pass the Agree to Terms & Conditions part as it still says I have no internet. Before the patch update I could at least access internet even though tab S3 thinks I am not connected to internet. Guess I have to try to root it or throw away the tablet.

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.

its protected by a paywall and might be a scam
so did u find the firmware somewhere else?

Can someone hack this firmware and stop it communicating with China's server? That's what they say in their agreement upon device setup. Also mobile network selection is locked to Auto only, this is annoying.

I am currently using that firmware, aside from unable to select network mode, did you happen to encounter loosing connection when wifi extender is turned off? My device seem to disconnect after few minutes if idle, but the problem is not occurring if the router is plugged to power or if the wifi extender function is turned on.

Disabling Sleep mode has no effect, or even setting it to 30 mins, before it reach that the router already unresponsive. Fiddling with my settings, turning on the wifi extender option is the only one keeping it active. And if i switch to using 5ghz band, a weird symbol appears. Something like a home symbol over the wifi signal.

Well, then you need to use recent official firmware, I don't have such problems there.
Where can I get one? I have tried all the firmwares listed in easy-firmware. And the sad thing with this, router prevents a firmware rollback. It fails to install unless its a higher version.
If you find a solution to this problem, I will be very grateful to you.I also can't figure out what the problem is, and no Internet helps me in this.
Today I turned this modem on and it updated itself, now wifi can work in 5Ghz. However, my carrier has blocked it's imei from using data.
Does anybody know how to change the imei on this modem? Maybe modified firmware?
