Question Wifi drops (connected without internet) - Samsung Galaxy Z Fold 4

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.

WiFi not working with VillainROM 5.3

Hi.
First of all, I installed it with a fresh new uSD card and a complete wipe.
While the connection seems to be OK, accordingly to the AP, no traffic can
be done accordingly to the phone.
Any idea? Is it a bug or what?
Weird. I have no such problems. Also, such a large bug would have been known much sooner. So it must be something unique to your situation.
Did you do a wipe before the flash?
Hi, this is not a bug, cause i have the same rom installed on my hero and my wifi is working.

Hi,
The wifi is working fine.
Make shure what channel your router is configured with.
VillainRom 5.3 is a Port from CDMA (US vertion of Hero) it only supports 11 channels.
We in Europe have 13 channels of our disposal.

Nice point.
1. I can see my phone hooked on my AP, so I would say this is not the problem.
2. The phone itself is showing the friendly WiFi signal icon.
3. VillainROM should put the regulatory domain back in the WiFi configuration.
And, of course, my WiFi is still not working!

I am having the same problem with my 2 heros.
both wiped multiple times and the sd card was repartitioned and formatted before flash. it will connect and allow some traffic but every 10-15 minutes or so it will drop connection then after a couple of minutes come back. I have watched the wifi indicator actually disappear for a few seconds then come back. never had this problem with 5.2 or any other roms where wifi was actually working.
Oh and I even reflashed the newest radio after words just in case and this didn't help.

Mine is a different problem, while yours seems to be an old one.
You can go to WiFi settings and check the sleeping mode to "never". You ask te system not to disconnect for any reason at all.

yes diferent problem, that option may solve the question.
Meanwhile this question might be stupid but just to make sure.
Uqbar does your AP has MAC filter configured?
Lol. Thanks I didn't even realize that advanced menu existed.I'm gonna give that a shot.

Nope. The AP has a very simple cfg (just WPA authentication).
My phone used to work with older ROMs and the same AP though.
Found this, might be useful

Check out also the comments.
I have experienced the OP's issue as well. Wifi works for a minute or two when first connected, but then the data stops even though the status still shows connected. I have to disable/enable Wifi to get it back.
I'm using a "g-only" network with WPA2 encryption.
I have been tinkering with the settings in the following file:
/system/etc/wifi/tiwlan.ini
I have had some limited success by changing DesiredPSMode to 1 (from 0). The phone now stays connected several minutes longer, but the connection still drops frequently. At least now it drops completely (status shows disconnected) instead of just going dark while showing connected.
I haven't had much time for trial/error with the other settings in that file.

[Q] Anyone else having wifi problems on cm10.2?

It shows I am connected but nothing is connecting to the internet. And no I do not have a firewall on.

Android 4.3 has been reported as having reconnecting issues with WiFi.
Have you tried more than one router? You may want to forget the router on Android and reset the router itself, this has helped me in the past.

I've tried forgetting and re-connecting it does not work. I can connect fine on other routers. Also, how do I "reset" the router?

To reset it all you should have to do is unplug it for about 30 seconds and plug it back in. There might also be a button in the back you hold down.

Yes it will, sorry I should have mentioned that. You'll have to add the settings back yourself.
It sounds like a router issue to me, since your phone connects fine to other routers, so this maybe your best option.
But you could also try another cm10.2 based rom (I'm on slim and have no issues) (make a nandroid of course) to see if that is the issue as well.
I've had my phone do this with a specific router before as well and resetting it fixed it for me.
EDIT: You could also try changing your phones IP address.
On your phone go to wifi settings>long press wifi name> click modify>check show advanced options>click DHCP and select static>change Ip(when changing IP only change the last set of numbers after the last period keep the 192.168.1.)
Is it 5Ghz band specifically that has problems?
I know I've been having problems with *just* the 5Ghz wireless SSID on my LAN (I'm on NovaGen latest) and came across another thread (I'd have to go dig around more) that basically said there's a known bug with CM10.2 where you have to have your SSID channel set below 48 to get CM 10.2 to connect. Hopefully that helps someone. Worked for me.
Wifi fixed! ^_^
My PC and device was using the same IP.

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.
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.

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

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,

Question Z Fold 4: Losing Network Connection When On Home Wifi (ATT)

Hello all!
Got a weird problem, that at first wasn't much of an issue. But now keeps getting worse and worse.
I'm on ATT btw
I've noticed that when I'm on my home wifi, I will randomly have the following issues:
I can't send or receive phone calls
I can't send or receive text messages
Anything network related just doesn't work
It's very random, but happens frequently, and if I turn on airplane mode then turn it back off, the issue is resolved.
I've tried:
resetting network settings on phone
resetting my home network
soft restart and hard restarting phone
I've tried connecting a router to the stock ATT router and using that as my connection
Everything I can think of, short of reformatting the phone completely which I will probably try later this week
I'm on the latest firmware
When the issue happens, I can turn off wifi and it will show 2-3 bars of network but no lte/5g/5g+ or anything. And sometimes it shows the circle with a line through it.
Thanks!

Nope, using a normal sim card from ATT.
Lucky a simple restart fixed it, I'm at wits end how to fix this issue....making work very difficult lol
Going to run phone without wifi today and see if the issue comes up off wifi.
Okay, so tested today without using wifi. And while not as frequent, it still did lose connection just now. And I had to toggle wifi off/on for it to regain connection....
Guess my last step is to reformat the phone
Just got the fold4 on T-Mobile and had the same issue over the weekend.
Randomly stops getting service, have bars but no data, sim says unknown. Disable then reenable sim and it works until next time.
Cleared cache, cleared network settings, remove and reinserted sim.
Today is my first day without losing network.

Just got the fold4 on T-Mobile and had the same issue over the weekend.

Interesting, going to try some stuff tomorrow to see what I can figure out.
I was away from my house and had no issues, so starting to think maybe it's my location....but not sure.
Interesting, I've been getting this occasionally on my fold 4 with tmobile. I'll have apps that wont update data with a 'you're not connected to the internet' error. I recently added duck duck go browser and enabled the app tracking blocker. I've been wondering if the duck go vpn is the cause. Do you use any sort of vpn?

Yeah I use ProtonVPN, used to use alwayson but ended up turning it off as it was interfering with my Tesla Key function. But whether it's on or off, I still get the issue.
I haven't reformatted my phone just yet, but the issue has reduced a bit the last few days. I'm not sold on it being my phone as this literally only happens while at home.....really bizarre honestly.
Also got an issue now with android 13 that it won't work with my Tesla half the time. It just doesn't recognize my phone as my key .-. really tilting xD

Thanks for the info. It's so intermittent it's very hard to pin down. I still haven't gotten the update to 13 so hopefully that helps you narrow your search some.

I've noticed it less with Android 13, but android 13 broke my Tesla Key functionality....so not sure that was worth the trade off xD
Yeah, I haven't been able to pin point any specific cause which is super annoying....
Well it lasted a day or 2 then happened a few times again.
As this was a new device for me, I noticed it wasn't "activated" on T-Mobiles site. I went through the activation process and that seems to have fixed it for me now (wifi calling too).
Likely unrelated to what you're experiencing but thought I'd mention it.

That's interesting though, maybe I just need to go talk to ATT as much of a pain in the ass as it is -_-*
