Z1C WiFi Issues? Speed/Stability

Hi all,
Not been around for a long time so its great to be back
Recently got the Z1C on Contact, frankly its the biggest regret I've had with a mobile device.
Is anyone else having WiFi speeds slower than dial up?
My download speed is < 250 KB's
Any1 else had this? If so does any1 know a fix?
Thanks

I don't have that, neither on 2,4GHz nor on 5GHz. You could try the unofficial DooMLord kernel, it mentions "custom built wifi wlan modules", dunno if that helps.

I'm not currently looking to Root/Unlock/Flash anything.
I'd just like my Stock Z1C to actually work with WiFi.
Its not exactly difficult, its seriously annoying me now, why is it so slow?

.. sorry just saw my solution doesn't help you and I don't know how to delete a reply...
but anyway, have you tried to close all apps on your phone?

my wifi works great too .. what rom do you use? latest .757 ? download .761 or 757 FTF and try to flash via flashtool .. No need to unlock bootloader or root, but you will lose some data if you don`t make any backup
you have a software problem there ..

I'll check it out when I get home but I never have Bluetooth on so I'd be surprised if it was that.
I have a gaming router which is extremely powerful and all other devices/phones work perfectly so I know that the Z1C is the bottleneck.
Any other ideas if its not the bluetooth?
Thanks

I've not had any issues with WiFi or BT, which is always on on my phone. I do use 5GHz for WiFi.

Have you tried restarting your router?
Does it go slow with every wifi? can you test it on different wifi and see if the problem is with one type of router?
Don't think I've seen anyone ekse with this problem, although flashing the .757 update messed up my bluetooth (then .761 fixed it).

Thanks for getting back to me
I have tested it on my work WiFi, I don't know whether it is coincedence, sod's law or normal but the WiFi on my Z1C at my work is absolutely rapid!!
I've just updated an app to test it, and it was at around 5MB's which is brilliant for me !
However, work WiFi is a 100MB's connection speed, where as at home I believe its around the 12MB's mark (geographic limitations in place here >.<).
From this I see only a couple of conclusions:
1 - Z1C and my home router just don't get along.
2 - As the WiFi speed is so much higher at work, so is the Z1C
or that theres no relation between the WiFi speed and my device but there is an issue with the Z1C WiFi itself?
I'm presuming its the first?
Thanks again!

Hi there,
I'm still on totally stock ROM.
I've done some testing and I believe it is on every router/internet but is very inconsistent. Sometimes its very speedy, others it will drop to almost unusable speeds.
I think I'ma just get rid of this terrible device, very disappointed in Sony. Here are some of my issues:
Phantom Touches
Unresponsive Touch Screen
Constant Crashes
Phone CONSTANTLY answers in Loudspeaker
Screen will not wake up
WiFi Speeds Totally Unusable

Just update to 14.4.A.0.108. It's also stock, official. You do not loose data while updating and it takes merely 10 minutes of "sitting back and relaxing"
As for wifi issue, did you try disabling wifi optimization fetaure found in advanced settings?

Have to be honest,
I got that fedup with all the issues on the phone, I sold it and bought an iPhone.
(Waits to be shot).
However I must say, iPhones feel very nice nowadays, nice and snappy etc.
But yeah, I'll still be hanging around these forums helping people out etc,

Hey that's a new phone just so you know because this is not acceptable.
Not sure about reclaims in your country but it should be valid in most?
Mine did about the same as my PC/PS4 = 60-95MBps, that is until yesterday
Both bluetooth and wifi are stone cold dead so I though I should reflash my ROM(Aur) and rushed it when I realized whilst doing the same 'ol start guide for the hundreds time I forgot to flash recovery :victory::fingers-crossed:

Happens to the best of us
Got rid of my Z1C, and got an iPhone (SHOOT ME NOW).
I just couldn't get past the myriad of issues.

WiFi not working properly v20b

I have installed v20b, everything works fine except WiFi: after sometime the connection just doesnt work and i have to turn off and on again the WiFi. This just happened to me at least 10 times

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 :/

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.

Whats the easiest way to unlock BL? do you have to download the file from android thats 1 plus gig big and do it thru that ?

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.
i.imgur[dot]com/JYI7b9I.jpg (sorry, can not upload pics)
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.

Nexus 5x wifi issues

Stock 6.0.1 mtc19v, on T-Mobile, july security update, never rooted this handset
I decided to start my own thread because I didn't want to hijack another's.
So here's the problem. Had my 5x for 3 days. And I love it, but it has weird wifi issues. I can't watch YouTube while I'm on wifi but it starts up with no issues while on LTE. Downloading apps and their updates take up to 20 minutes. While it's instant on LTE. Wifi calling is super choppy too. And my 5x occasionally disconnects too.
Everything else works fine on wifi. Chrome is quick, so is feedly.
So I searched here and on Google and many people have the same issue. Some say 6.0.1 was bugged.
Either way I tried all the advice given to others. My router and modem are up do date. I reset them various times. The problem can be replicated on my sister's wifi and my dad's.
Check my phone's APN. Changed to 2.4 and 5ghz bands on the phone. Went back to auto wifi band. Nothing.
Tried safe mode. No dice.
I even wiped. No luck either.
I also tried wiping the data and cache on a few apps, play store being one of them. Can't remember the other two.
Anything else I'm missing or is 6.0.1 really bugged?
Is there a possibility mtc19z has a fix? I haven't received that update yet.

Forgot to mention
I called Nexus tech support. They say it's not a known issue. Project fi's tech support said the same thing.

Try with bluetooth turned on, doesn't need to be connected to anything.
Also try enabling developer options enable the setting to use lollipop dhcp client.

OK I'll give it a shot

OK so far, Bluetooth on does nothing for me. Apps still download slow and wifi calling does nothing.

Hi man, the lollipop dhcp didn't work. Tried it with Bluetooth on and off

Last option I can think off.
settings/backup & reset/network settings reset.
After that I would try doing a clean flash with the latest stock image, no apps etc and see what happens.
If that doesn't work I would return it for a new one.

Tried that too. I'm stock never rooted. I've wiped twice already. Nexus support is barely any help. But yeah I'll try for a swap. Thanks.

Well project Fi couldn't help since I don't have their services. LG keeps telling me to call Nexus. Nexus keeps transferring me to project Fi.
I'm just gonna go buy another phone. This hassle isn't worth it.

My N5X has not had any wifi issues, thankfully, but I have had weird wifi issues on other android phones in the past. What has worked for me was to go into my router's settings and use DHCP Reservation to assign a specific IP address to the phone, and to make sure there were no conflicts in the IP assignments of various devices on the network. I also replaced the router's default DNS servers with Google's.
Those two steps have solved my android-related wifi issues in the past. But, again, I haven't had any issues with the N5X so this may or may not help you.

Nexus 5x wifi + Bluetooth.
So couple of years i use it without bluetooth turned on. With some wifi access points phone can't get in deep sleep. Some other access points sending packets to phone.
One day a read about bluetooth "on" options. And surprise, now phone can go deep sleep and dose not have battery drain.
Now i have to keep my bluetooth always on. Was same for android 6,7,8,8.1. with factory reseted.. different kernels dos not help.
Maybe some heard - it is hardware issue? Its go under warranty?

Question Problems with mobile data - Stop working but looks good

Hi,
I own a Xiaomi 11 Lite 5G NE. I have updated to the latest MIUI Official V12.5.8.0.RKOEUXM.
From the beginning, I'm facing the issue that mobile data is not working. You're navigating and suddenly all stop and finally it shows the error no network.
After restarting is working fine again but it's very annoying. I've been looking for help but nothing found has helped.
Is anyone else facing this issue?
Thanks for your help and time!

Post seen by 26 people so far and no answers.
I suppose then mobile data is working fine for all of you... Mmm... My bad, it looks I will need to use the guarantee...

My mobile data works fine, but i noticed that phone sometimes drops WIFI connection.

Hey. There
For some Days I also having mobile data problems. My phone så browser says No internet connection..
When i turn phone off or disable mobile data off for 30 min IT Works for a short period, then IT stopps again. I can use Wi-Fi at home.
I have factory restored my Device but its didnt helped. Swiched to second sim slot and nothing..
Gould be cool od someone knew how to fix it. Or need to send it in. Had this phone 3 months .
Specs..
Xiaomi 11 Lite 5G NE
MIUI 12.5.7.0 stable
Model 2109119DG

Same problem here. I'll preface this by saying that I work in a place where the reception isn't great, but with my old Huwaei it never happened.
When I lock the smartphone and then unlock it after a while it shows 4G+ but in reality there is no connection.
Last night at the gym (in a basement where the reception is zero) after I left it wouldn't pick up the network again.
To solve it I have to put on and take off the airplane mode.... Very very frustrating.
I also replaced the sim card with a new one but no dice.
MIUI 13.0.5.0 Stable

Thanks all for the replies.
So I'm not alone, but it looks that some people have not issues.
Looks also problem is on MIUI 12.5 and also on MIUI 13.
I think it is a hardware problem, not software.

In these days Ill take it in assistance and I will update you.
Unfortunately, it has been too many days since my purchase and I can no longer return it. Super regretful that I didn't get a samsung a52s!

Need to that we had igły weather here with lightnings and storm . Many trees was Tilted.
But checked mobile operatora site and nothing there.

Thanks, let us know what they say.

Hey again.
I have talked with my phone carrier..
Tv'et said that there ser problems with the antennas or something and in some Days they will fix it . They said i need to chance from LTE to 3G till its fixed..
They should have write something on their homepage. Will have helped , so I didnt had to factory reset.
That's All for now.. Have nice weekend you All.
Hope you will have yours problem fixet.
Bye

I also had major issues with my mobile network on 1 of the simcards. (I am using dual sim)
If your provider supports 5g then call with the dialer *#*#4636#*#*
you will see a menu with 3 options. the first selection is simcard 1 the second simcard 2.
change the prefered network type to NR / LTE / GSM /WCDMA or whaterver ur provider is supporting, NR = 5G network.
Make sure you disable VoLTE for both the sim cards since this was disabling my download from mobile networks.

hi guys, yesterday I took my cell phone out of repair. They replaced the motherboard and now it seems to be working fine, no signal loss.

Hi Raulci, i replied u in the other thread!

Just wanted to let you know that during the last weeks, I haven't experienced any other mobile data issue again. I have changed anything. Let's see if it continues this way.

Yes its a problem. Initially i thought its miui 13 problem. But reading above comments with slow speed/ 4g connectivity issues in 12.5 it seems its hardware related. Inferior modem or low quality antennas could be the case. I was hoping to fix by reverting to 12.5.

Same problem i have mi 11 x i even go to the service centre they factory restart my device and it's not fixed they said it must bu hardware problem

Question Wifi drops (connected without internet)

Hi all,
Been playing with the z4 a few days. It's brilliant if it weren't for a wifi issue. A few times per day it shows the wifi symbol with a ! i.e connected without internet. It's the only product connected to my home wifi that has issues when it happens.
Any suggestions what can be done?
Thanks,
Mark

I don't have this device, but I have suggestions.
- Try to reconcile the protocols on the router and the phone.
- Turn off battery saving features when wifi is not in use.
- Set up a wifi connection on your phone, a persistent connection, or something similar.

If you used SmartSwitch, you may want to reset all the network settings.

I'll remove all the Bluetooth and wifi settings and start fresh. Can't imagine it's hardware related. Thanks

Hi mattcall,
Yes it did. Pressed forget the network, restarted the phone and added again. Hope it works for you too.

Well apparently it didn't help. Had same issue this morning twice, just sitting on the couch. So not related to switching between wifi repeaters.
Maybe we'll have to wait for first firmware update, since I'm on a pre-release with security patch July.

I'm having the same problem with an Asus router. It's been very intermittent for the few hours I've been using it.

As soon as I go in my bathroom the fold. Loses connection but my s21 ultra is fine also Samsung internet on Samsung website keep freezing page unresponsive

I noticed that when this happens the "up" arrow is constantly on, while in normal conditions both would go on and off when sending and receiving. Maybe router related, but all the other Samsung products in my household don't have that issue and there's plenty.
