H850 Wifi Authentication Problem - LG G5 Questions & Answers

The wifi randomly disconnects and with the error: Authentication Problem. The phone wont reconnect to another wifi hotspot until I manually make it do it. This happenns on the 5GHz band (I haven't tested it on 2.4). This problem doesn't happen with any other device connected to the same wifi router. Does anyone know what could cause this problem?

I had a similar problem where my G5 took ages to connect to WiFi and then it would randomly disconnect.
Try deleting every saved WiFi network you have, except for the ones you use. Just long press each one and hit "forget".
See if that fixes your problem.

I have only 2 saved networks (the 2 bands: 2.4 and 5). The wifi worked without any issue for the last two weeks until yesterday when the phone disconnected with the Authentication Problem error. I have to mention that the phone connects immediately to the wifi if I manually select the network and when I turn on the wifi.

I would then suggest the problem is with the network.
Either reset your network (unplug router, wait, replug) or try with a different WiFi.
I had an outage a week ago and that problem persisted until my provider fixed their problem. These "authentication" issues can be from anything network related.

I will try with another router. The annoying part is that I cannot reproduce the error manually, it's way too random.

[Q][Help]Wifi only works 3 meters away from router

Dear All ,
I have been suddenly encountering wifi connection issues with my S3.
It refuses to connect to any router unless i am very near to it.
There is no problem with reception as the phone can detect the wifi and has 3-4 bars
If i try connecting while far away from the router to a detected network, it just gets stuck on "connecting.."
If i connect while near the router and then walk away, remains connected but I have no internet access..
Things I have tried:
1-cycling wifi on/off , reboot phone, reboot gateway
2-turning off wifi power saver from service mode *#0011#
3-flashing a different non stock rom after doing a wipe/factory reset.
4-searched extensively for three days with no avail
If any encountered such a problem before and was able to solve it, your help is highly appreciated.

I haven't encountered this specific problem before, but I have had other problems with my S3 and WiFi. It turned out the problem was my router, which was in 5ghz mode. If you have a 5ghz router, try to switch it to 2.4ghz.
Something else you can try is to change your modem and/or kernel. Those 2 both have something to do with WiFi, so maybe it'll work.
Again, I haven't encountered your specific problem myself, these are just some suggestions.

I'm having the same problem for about 2 months now, it's driving me crazy, if anyone knows how to fix this please let us know! Thank you in advance.
AS the guy above you suggested try changing your modem and if that fails try a new kernel which should sort out the problems you are having. Or as he also suggested try your router and make sure it isnt in 5ghz mode only.
Try logging into your router's configuration and changing the wireless network channel from auto to a manual setting (e.g. 9 or 3). The only wifi problems I ever had with my S3 were (misconfigured) access points and routers.

[Q] Loosing wifi network connection after a while.

I am using SHOStock 3 3.0.2 on my i777.
I just changed my router (TP-LINK TL-WDR4300 with DD-WRT running) and strange thing began happening.
When I connect my phone to Wi-Fi everything works as usual, then after a while (maybe about an hour?) no connection to network at all.
WiFi signal is strong, has IP Address assigned, router sees the device. But, cannot ping in or out. No connection to network at all.
If I disconnect from WiFi and connect again, it works for a while, then same thing happens again.
No other WiFi device in my home is having that problem.
Any ideas what might be the cause, anything I can try?

I'd do a factory reset first to isolate whether it's your phone or your router causing the problem.

Wi-Fi Connection Problem

Hi All,
I just received a replacement for my V10 that suddenly died and I'm now having Wi-Fi connection issues.
When I brought it home yesterday the phone was still on 5.1.1 but updated overnight to 6.0 both experienced the same issue.
I have not rooted my device yet but will in the near future.
I have 3 different access points in my home with different id for each.
I can connect to one of them but not the other two.
When I try to connect it I eventually get a WI-FI connection error, or the connection is labeled disabled, or the connection doesn't connect and just shows saved.
I have tried:
1) reset the router
2) changed the password
3) changed to an open connection e.g. no password
4) forgotten then connection on the phone
5) restarted phone
none of these have fixed my issue.
Anyone have similar issues?
Anyone have any ideas for a fix?
Thanks you all for reading my problem.

Just started having a similar issue yesterday. Stock MM, no root. Factory reset had no effect.
Maybe you can join my thread, I have problem with wifi also. You can check if we have same issue and may try my workaround http://forum.xda-developers.com/tmobile-lg-v10/help/wifi-mac-address-changes-reboot-h90120j-t3470140
I actually just noticed this on my phone yesterday. It seems to happen to me when the wifi signal is a bit weaker (but should still be able to connect). My wife's V10 didn't have an issue though. Haven't find a solution yet, but my wifi would also not find any connections after it would disconnect and have to rescan to locate any networks.

Have you tried to do factory reset?

WiFi Reconnection issus

Anyone else having problems reconnecting to a WiFi connection, or even seeing WiFi SSIDs after disconnecting from WiFi?
This happens to me intermittently. I have 5 WiFi SSIDs in my house. 2.4G and 5G from the FIOS router, and the same from a WiFi access point on another floor at the other end of the house, and a Guest network from the AP. I can normally see all of them from any point in the house, as well as half a dozen from nearby neighbors. And my s9+ normally connects, automatically, to my primary 5G connection without any problem.
But occasionally, after being out and coming back home, or after the phone has been asleep for a while, it won' see any SSIDs. Not mine, or the neighbors. I've tried scanning for WiFi networks, turning WiFi off, waiting a few, and turning it back on, but it doesn't see anything, and won't connect. I've even tried manually inputting the name of one of my access points, but the phone won't find it.
Turn on WiFi automatically is on, WiFi power saving mode is off (although I've had the same issue with it turned on), Keep WiFi on during sleep was set to While charging. I've changed it to always, but it will be a while to see if that helps.
The only way I've found to get it to see WiFi networks again is to reboot the phone.
Oh, and other devices, including other Android phones, see all the SSIDs without issue.
Any thoughts or ideas?
I have te same issue here, I can't find a fix.
Mine will not connect to mobile date after I turn my wifi off. I have to reboot the phone in order to be able to make a call or use data. It all seemed to happen when a pop up came on to enable wifi calling. I can't figure out how to turn that off.
I don't have acupp1's issue with mobile data, but I seem to have resolved the WiFi connection issue by not letting the phone turn WiFi off during sleep. Haven't had the problem since I changed that setting.
I got the same problem since I rooted
Been trying to figure out if its a VENDOR Firmware problem or what. I do know that every developer says its a bug with the s9 when rooting. I've personally watch the live log on TWRP when flashing and seen where it mounts the VENDOR Firmware and then unmounted at the end. So it could possibly be a problem between TWRP and the s9 ROMs idk know exactly yet but I'm looking for a solution also. But I'm going to try what you did with your WiFi then report back here.

Question Wifi Connection Problems

Hi guys i just received the edge 40 pro. when i try to connect it to my router it keeps connecting and disconnecting without stopping. I tried shared wifi from my other phone and it worked perfectly. all my other devices connect perfectly with my router so does anyone of you have this issue. i tried rebooting last update tried reseting network setting and even the phone but still nothing
Will keep it if anyone face same: the problem will accure if disable ipv6 on your router setting for local network enable that and it will work ass expected
