Is anyone else having wifi issues?

Ok so in the past hour I've noticed that my phone has disconnected from my wifi a few times. It does connect straight away however when I try to load a page it won't load and I have to wait a little while longer until it works again.
Has anyone else had wifi issues with this device?

Any body have any wifi issues at all?

Yeah I'm having the same issue with my home's wifi.
Doesn't seem to occure at work though(or maybe I haven't noticed it since I do work there).
Talking about the 4g version.

Hi, thanks for the reply.
Apparently this is a common issue with the S4 as well. I did update my routers firmware yesterday and it didn't disconnect at all last night however ill keep watch on it.
have you tried anything to fix it?

I don't want to void the warranty though... I'm thinking it maybe a router issuer and not a firmware one...

Haven't tried anything yet.
I'll probably try flashing the latest fw at some point - which I think doesn't void your warranty.
If you find something out, let us know. I'll do the same.

I've got a new router coming from Sky. (Sky Hub.) I'll see how that acts before I flash my phone.
Let me know how you get on.

Can anyone explain how to get the MH5 Firmware and what steps need to be taken to flash it?

Yes I am too. I made another thread asking if people knew if the 9190, 9192 and 9195 have different wifi antennas. I am really bummed out over this.

Can you describe the wifi issue you have? What FM are you running?

No Wifi issues here.
So I did have issues, but that was the fail of Xposed-Framework, without that framework, there is no problem.
As a matter of fact you are able to stop the Wifi Power Safe Mode und the Service Mod (*#0011#) ... That stops a lot of Issues

Doing that will drain battery though. It isn't really an ideal fix...

Anyone else?

[Q] Problem with WIFI auto connect in Android 4.3

Ok, So this has been happening for a while. I kept looking up for a fix, and i finally foudn this issue ticket open that looks like others having the same issue, and it appears to be this specific phone.
Is anyone else having this problem and is there an easier way to solve it than resetting the device?
Goggle issue 58230
I will copy the first post, as it pretty much mirrors my experience.
My wifi is always on (turned on the option for keeping it on even when the phone is idle). With older versions (4.2.2 and older), when I arrived at home, the phone automatically was connected to my home wifi.
But when 4.3, sometimes it doesn´t connect until I enter the wifi menu.

My issue extends to work as i work at a school, with many different WAP's, and this occurs sometimes when switching WAP's as well.
Thanks

Lyian, I have the same issue as well, on google stock rom as well as all the modded roms, whether 4.3, or 4.4. I may have to junk my (otherwise perfect) phone just for this. I don't see any solutions anywhere.

try to reset your phone it should help and backup before i am also on v20b and no problems with wifi on my phone till now (upgraded and factory reseted)

I did it before flashing the rom because i was on cm13, dont think that another reset can help :/

I do have this on IEEE 802.1X networks only. Also on Android 5.1. This seems to be regardless of root/no root.

Had WiFi dropouts on every LG ROM on this device.
It would drop on any WiFi network I tried. My old phone and all other devices have no issues at all.
Bit the bullet and unlocked bootloader and went to CM13, rock solid WiFi now. IMO LG's software is borked.

Right now there is only one way: LG Developer program.

I think that is problem with 6.0
My network is ipv4 and i think phone force ipv6. In developer options have option to use lollipop settings but i think that is not doing any better

There was an issue with Verizon 12B that was recalled with similar issues.
Never had Wi-Fi issues otherwise. It was patched in 13B

Same with me on 20a... wifi connects but there's no internet connectivity. Then it comes good for a while but eventually drops the wifi connection completely. Sometimes it forgets the wifi password and I have to re-enter it. Makes the phone essentially useless on wifi. A factory reset seems to be the next step unless anyone has any other suggestions?

Same problem on 20b

The WiFi problem seems to have settled down for me now. I went on a binge of uninstalling and reinstalling apps, cleared all app caches, rebooted several times, and recited some incantations (mostly beginning with f). I haven't spent a lot of time using it on WiFi but it seems a lot more stable. Will keep an eye on it and see how it goes.

I came back to a stock based ROM from CM13 because the lack of camera functionality and all my WiFi dropouts are back again. This is really disappointing with this phone as it is completely random and none of my other phones/devices have ever had problems like this. End of my tether with it to be honest, this phone will be going on eBay at this rate.

Well I've been running catlog tonight and it didn't take long for the WiFi to blip.
If there are any catlog experts out there I would really appreciate it if anyone could have a look to see if there is any indication of what is causing this random disconnection and then reconnect shortly afterwards
Many thanks in advance.

Sorry, can't help with the catlog. But having same problems.
I did 3 hard-resets with always the same result: wifi works fine for 1-2 days, than breaks.
The connection is strong an seems stable but data-throughput and ping times are ugly (0,4 Mb down, ping around 2-3 seconds).
Here's a screenshot that perfectly shows the impact: same phone, same setup, same wifi. just 1 day between the tests.

Any ideas how to fix this? a DNS problem?
btw: IPv6 is disabled on the router.

I have the same problem and i found a solution for me. I'm using pebble smartwatch with G4 and i noticed that when i disconnect my watch or turn off bluetooth, wifi stays stable. If you have a bluetooth device like me you can try this method.

I've also had my G4 get into a state where Bluetooth is stopping WiFi from working. I posted a thread about this here. To summarise, I've twice gotten into the state where my WiFi disconnects whenever I put the phone to sleep. When it wakes up, it takes ages to reconnect. Sometimes it fails to authenticate and forgets the password for the WiFi network. Even when it is connected, the connection is very flaky. This only happens when I'm on a 2.4Ghz network and Bluetooth is enabled - if I disable Bluetooth or switch to my 5Ghz network then WiFi is ok.
I've had this happen to me twice now... the first time was straight after the update to MM. I fixed it by uninstalling and reinstalling apps, and eventually it came good. After a few weeks the phone got into that state again. I tried clearing cache, factory reset, and reinstalling MM using the LG Bridge "Update error recovery" option and nothing helped. Once again I went through my apps one by one and uninstalled and reinstalled them and once again the phone came good.
This is a huge pain in the butt... not sure how long the phone will hold out before it gets into this state again. I really hope there's a MM update that addresses this soon.

I've noticed my Bluetooth problem in two ways. One of them was connecting a Bluetooth speaker while the watch is connected. When i connected speaker too, wifi had no issues.
And the other situation that i made my wifi stable was going into safe mode. Even Bluetooth on i was able to connect and stay connected to wifi when i was in safe mode.
Which apps did you have to reinstall? Do you remember?

I just started going down my app list and uninstalling apps which looked like they might have something to do with bluetooth, then putting the phone to sleep and waking it up to see if the problem was still there. I got a bit slack and maybe uninstalled two or three at a time before testing. I should have been more systematic about it but I wasn't really expecting it to work. I'm pretty sure the last one I uninstalled before things started working was TuneIn Radio so if you have that installed you might want to try uninstalling it. I've since reinstalled it and WiFi is still working.

wifi keeps disconnecting on nougat

Anyone facing this issue
Does anyone know any fix

Yes mines the same, wifi works fine for a short amount of time then disconnects, after it cuts out goto wifi settings and all I see is scanning and no wifi devices. only way I can get wifi working again is a reboot but then I get disconnecting again after short period of time!
EDIT: I would just like to add until I updated to nougat yesterday I've never experienced this issue and I did a master reset straight after installing nougat.

I am having this same problem. Any fix for this?

Same thing here. It happened to me after the first night. I thought maybe something was corrupted after the upgrade, so I did a full factory reset yesterday morning. Everything worked fine until I got up this morning. Looks like something over the course of the night causes this to start.
Things I've tried without success:
- factory reset
- rebooting
- removing and re-adding wifi network
- tested all other devices in the house (no other device is having an issue)
- tried both 2.4 and 5ghz networks (issue is affecting both)
UPDATE: After a few hours, I turned wifi back on yesterday, and it's been working fine since. I made no changes to the phone.

Faced same problem with developer preview
Before the official release of Android 7.0 I installed two Android beta preview, 3 and 5, and had the same issue I uninstalled the previews and had no problems with version 6.1. I hoped that this would be fixed with the official version but It wasn't, Im still facing the same problems with wifi disconnecting.
Edit: When I had the previews the only way that the phone would seem to remain connected was to go into the router options and change the client lease time. I never fully tested this because I uninstalled the previews within a couple of days. I guess I'm going to have to test it this time.

Maybe this thread could help you guys, didn't try, and as it is for nexus 5, do every operation carefully.

Flashed back to 6 as the WiFi issue was unbearable, working perfectly fine again now. I was also getting major battery drain on 7.0.

Hi
I found a strange solution working for me. I had bluetooth disabled, since I have enabled bluetooth today, 5 GHz connection is stable - Pls test it and update. And pls don't ask me, why these two protocols are in any way related...

Didn't work for me.
This problem had disappeared for weeks and then started rearing its head again yesterday although I had made no changes to my phone. For the record, it's happening on both frequencies for me.
Last time, the issue magically disappeared. After it didn't go away over night, I restarted my router this morning, and now it's working fine.
To clarify, I don't think it's router related, though. I have an R7000 that's working perfectly with all other phones and other devices in the house. It's the same router the 5x was connected to before Nougat started causing these issues.

Wifi and Bluetooth stop Working constantly

Hi,
I'm with the A50 for 3 weeks now. In the last couple of weeks I have a very annoying problem. A few times a day (sometimes 5-6) the phone disconnects from the wifi network and turns off the Bluetooth with no apparent reason.
When this happens the Bluetooth is actually turned off (not just disconnects). When I try to reconnect to a wifi network, I cannot (no response from the phone, although it does recognize available networks) and also the Bluetooth cannot be turned on at all.
The only way out of this is to switch to flight mode and back. That resolves it and everything goes back to normal. Then it can happen again in a few minutes or a few hours.
Anyone have an idea what's going on before I throw this phone away?

I thought I'm the only one facing these issues (in my case its not as frequent but its there). I also noticed that when changing EAP settings in certain wifi coneections, the settings app just force closes. Contacted customer support and they recommended doing a factory reset!

There is a big problem on this part of the smartphone, I encounter a problem with bluetooth and the wifi tends to cut also by now, but it returns to normal without going through the airplane mode for me.
I do not know if it's a hardware or software problem, but I think I'll return the smartphone to Amazon and go back to my S7 Edge

Can also confirm. Finished a factory reset now and I still face the same issue with the FC on changing EAP setings. Wifi keeps dropping. Unfortunately mine was bought from mediamarkt about 8 weeks ago. I'll contact the customer support again and see what they recommend.

I have similar problems with BT connected Samsung Galaxy Watch.
What I observed: when I switch off 2.4 wifi ( or "forget" all known networks so the phone does not connect ) then BT connection with watch works perfectly.
Strangely enough when I am connected to 5 GHz wifi BT seems to work OK.
So in my case: BT and 2.4 GHz wifi running together causes problems
As I saw in May update Samsung declares fix for wifi performance.
Let's see what happens

I don't know about bluetooth issue but I do have wifi issue, sometimes the wifi is not working so I have to turn it off and on again to fix it

I just spoke to Samsung Germany today and they told me they are aware of this problem and it should be fixed with the next update and that they are working hard to get out until the end of the month. At least some hope.

Strange issue with Wi-FI and Night Mode
Hi there,
I'm on the latest May '19 update with my A50 (A505FN) and just discovered a very strange issue: when Night Mode is enabled, I can't change advanced settings on WiFi connection, or the Settings app will crash as soon as I tap on the "IP Type" or "Proxy" option.
If I disable Night mode, then everything works fine and I can successfully change the above settings.
Think this is a SW bug...
Did someone experience the same behaviour?
Thanks in advance,
Max - Italy
