Question SM-F936N major wifi issue - Samsung Galaxy Z Fold 4

Hello,
My SM-F936N is on latest Samsung Android 12 version and I am experiencing serious wifi speed issues.
As soon as I start to watch a video on YouTube for instance, or I download a couple of apps the internet speed drops from 200mbps to not even 1mbps. All the time.
The only way to temptation workaround it is to either turn Wi-Fi off and back on or reboot the device.
I am going mental and not sure what to do. I saw few people complaining of the same issue on reddit. But that's that.
Any idea? Thanks

Looks like Mac Address randomization is the issue.

[Q] Wifi Dropout Problem Persists: Someone, Please Help!

I'm getting really frustrated now. This problem is a real nuisance for me, as I use my Desire a lot solely for this purpose.
In my room, the wifi signal has always been pretty weak, generally only getting 1/2 bars. However, the connection is stable and still about 6mbps. This is never usually a problem for my Desire, it picks up the connection and everything works great. Stock Froyo, Sense Froyo, Sense Gingerbread, Sense V2 Gingerbread, Miui Froyo and Miui Gingerbread all operate flawlessly.
However, I now have a bit of a problem. It seems most Gingerbread AOSP ROM's cause the wifi to play up. I have tried GingerVillain, Oxygen, Redux and finally now my favourite CM7. The wifi constantly drops out and loses connection, and then takes a good 30+ seconds to reconnect. The dropouts can be as frequent as every few minutes, and generally it never lasts 4+ minutes in iplayer without losing connection. If I am just casually browsing, I don't notice. But when I am watching something on youtube or iplayer, the constant dropouts make the experience so horrible it isn't worth the effort.
What's more, there is some odd bug with the iplayer app where once a dropout happens, the audio and video goes out of sync and so on etc. All in all, it makes streaming video unusable, and this was a main reason for me buying a smartphone.
I really don't know what the problem is, but I really would appreciate some help. I would say it was a gingerbread problem, but as stated above, there are many gingerbread roms which don't cause me the same issue. Similarly, I've used an array of different radio's and kernals on each ROM. They make no difference. It depends purely on which ROM I am using. I've tried resetting the bt home hub, restoring it to factory, changing security type, moving it's position and so on. I'm pretty sure it's a ROM / Phone issue though as it works fine with other ROMS. Phone wise, I've set wifi policy to never and set a static IP address. It makes no difference. I still get wifi dropouts!
For reference sake, I'm using the latest stock Radio - 32.49.00.32U_5.11.05.27 and Kernal 2.6.37.4-cyanogenmod-82245..... and obviously CM7 7.0.2.
Please someone help? I'm actually considering upgrading just to solve this. It is absolutely doing my nut in, and I am totally out of ideas or solutions.
Thanks.
Maby a weird thing but on what channel is your wifi broadcasting ?
I had almost the same problem when my wifi was on channel 12. Now on channel 3 there is no more problem.
Not that any other wifi's broadcasting here. It is just that I've got the feeling that android has a problem with "high" channels.

It was on 10 and 11.
I'll switch to 3 and give it a try. Also, I'm going to try flashing the Gingerbread Sense Drivers and RIL.
Hi,
I've also had a similar problem for quite a while now (1-2 weeks). I used my wireless connection on my standard out of factory ROM on my home wifi network, my families wifi networks and my work wifi networks without _any_ problems.
When this problem started acting up I'd start my wifi connection, it would work for like a minute or so (not dependant on the amount of data transmitted or something, idle would last as long as while downloading), and then lose connection.
The strange thing is that it indicates it is fully connected at full strength but can not establish _any_ internet connection whatsoever.
My 3G connection to my network (I live in the Netherlands) works nicely, but it isn't as fast as wifi, so this limits me quite a bit (especially at work, indoors).
I've just tried to upgrade to CM7, but doesn't give any better results. I haven't tried upgrading my RADIO, but I don't really want to if I don't have to.
Any clues what I could do to fix this?
I'm experiencing similar problems.I changed from channel 11 to 4, but it really hasn't helped. I have also set up a portable wifi (netcomm). It runs on channel 3. The network sim is quite slow but the signal strength is much steadier. My faster speedstream completely drops out. I understand this "pulsing" of signal is normal, but mine is beyond the pale.
My acer netbook doesn't demonstrate any dropout issues.
Im running an A501 3.0.1. No upgrade yet for me here in australia. But, I'm wondering if this is just poor hardware.
could try a different Radio.. the latest stock one from the new official gingerbread is in my signature..
MD5: 432ED609D76AE57BA493DA875CDC9D2D
further to my difficulty with wifi drop outs, I'm pleased to say that it appears that my problems probably are related to my home wifi, a Speedstream.
I'm currently spending a week on a houseboat and I've been using a netcomm myzone wifi fitted with a sim card from a prepaid Dodo broadband usb.
I've not had any problem with it. Granted, I've had it close by, but it still seems to work fine when I'm at the other end of the houseboat.
So my acer A501 seems to be behaving itself here. Perhaps, something is causing the speedstream to vary it's signal strength so drastically.
@OP - I posted a thread a few weeks ago about having exactly the same problems as you with AOSP ROM's and weak wifi signals. Once I went to a Sense ROM the wifi signal was great. I prefer the AOSP ROM's so I upgraded my Radio to the latest version but it didn't help at all, I didn't see any change when using wi-fi analyser.
I'm currently using CM7 ROM and just putting up with the weak signal. I'm glad it's not just me though.

2 Issues with Galaxy Nexus: Wifi + Multitouch, temporary fixes inside!

Issue 1: Multitouch issue
- As far as I'm aware of, there is no fix yet and a lot of people are experiencing the issue. What happens is whilst in landscape mode, sometimes, if one finger is placed at the bottom left of the screen, and another is placed on the bottom right, it'll fail to recognize the second touch (bottom right). This doesn't always occur, but does happen at times.
Simple fix: Lock the screen, then unlock it
Issue 2: Wifi consistently dropping
While downloading files, or sometimes even watching youtube videos, the wifi icon will disappear for a split second, then come back and an error will appear along the lines of " File could not be downloaded due to an error" or in the case of the market, it'll just stop downloading and give an error.
Fix: Sadly, the only fix that I have found so far for this issue is to get a new router. See my post here I used a Linksys WRT300N
EDIT: Another potential fix is to change some settings with the router but I'm not sure exactly what settings are needed to be changed.
EDIT2: I've created an issue about the wifi issue over here and according to [email protected]:
Im assuming you are downloading huge files using WiFi... there is a notorious bug still unresolved on DHCP leasing time. If your route is settled to infinite (0 or ffffffff) a local timeout of few minutes is applied, thus the download broke and resume time by time because dhcp renewal. To fix this try to adjust your route settings indicating a discrete leasing time (i.e. 24 hours or 2 days) and thi should fix this specific issue (also noticeble when watching youtube videos, that may freeze after few minutes).
Hope this helps.

Hey everyone,
I have had my Galaxy Nexus from Bell for a few days now, and it is a beast Everything runs smoothly, no lag (even with live wallpaper) and helps me accomplish everything I need from a mobile device ( a hell of a lot better than the milestone - international version of the Droid)
However, there are some prominent issues throughout the device.
1.) The wifi constantly times out, it will stop working at random times even if im 1-2 ft away from the router. Also, when I was downloading SD files for a game (asphalt 6 - 524mb file i think), i had to restart the download at least 10-15 times to finally get it to download. Is this a hardware issue? Can this be fixed through a software update
2.) The multitouch doesn't work at random times. For me, whether its plugged into the charger or not, at random times, when you touch the left side of the device in landscape mode, the device will not recognize touch inputs on the right side. HOWEVER, if you lock the screen, then unlock it, it works flawlessly. I am determined this is a software bug (may not be though) and if it isn't could someone please tell me? Thanks. And a lot of people also have this issue : http://forum.xda-developers.com/showthread.php?t=1385587

I have two question for you awesome people at XDA.
1.) Could someone please either post an issue to Google regarding these two issues or direct me to a website where I can post them?
2.) Could any of these be a hardware issue? Do you think I should return it and get another one?
Thanks so much guys,
Mosh
Would also like to know if the second problem is software related or not :/
EDIT: noticed now that my screen gets really hot at the top. Really hot! Does your get warm aswell?
Don't know. The easy fix is to swap it.

Both my touchscreen and WiFi have been working flawlessly.
I did have some initial hiccups with the WiFi until I power cycled my router.

I've been having WiFi trouble with the Nexus too - the phone generally seems to get poorer signal in comparison to my other devices. I've unticked this box, but it still keeps avoiding connecting (and when I go to WiFi settings, actually says it's avoiding connecting to my network because the connection is poor). It's frustrating, to say the least.
Rather than immediately assume that you should swap the phone, or thinking it's hardware, or (?).
What build do you have? There are at least 3 builds available for the SGN.

Seriously people need to stop making such a big deal of these separate builds.
WiFi could be an issue with the router. I had a problem where connecting Nexus to the router would cause both mine and other users internet in the network fail. Once I disconnected, internet returned. It worked on first few loads, then not anymore. Strange thing is that it fixed itself few weeks later.
(Same happened once with another router and when I was using HTC Desire, Android seems to be a wacky WiFi partner)

Not this. If its software you end up with another phone with the same problem.
You may find other radios help with wifi, check the dev section for details if you have a rooted device. Otherwise youll probably need to wait for one of them to drop via an official ota.
As others have said, uncheck the weak wifi option
In terms of the multitouch issue, just tested my device and can't see any issues at all. Could be software related as the screen itself can support 10inputs - be interesting for users on non standard roms to check and see if they do have a problem as this may lend some weight towards the software related argument.

I get #2 in shadow gun if it goes into sleep mode while i'm playing. Its clearly a software issue as restarting the game it goes away.
Point 1 happens to me too. I've tried multiple ROM's. I'm getting a bit worried that it's hardware. It's dropping every few mins when I need it... then it comes back rather quick.
You have any news or has anyone else experienced it?
I'm not seeing a ton of people talk about this wifi problem, so I'm guessing it's not a widespread issue. I'm assuming it's not hardware either, but I'm curious about it. Whenever I turn on wifi on the Nexus and it tries to connect to my router, it disables all other connections, and the Nexus reports that it's not in range of the router. I'm interested in what routers people are using that are experiencing this issue.
I have a D-Link DI-624, a free router provided by Verizon with FIOS signup. I'm using a custom password, not the one that came with the device. I have a 13 digit alphanumeric password (sorry, I can't remember the exact security setting for it).
Edit: Actually been doing some research on this, and it's appearing it may be a frequency / channel issue, that the phone is broadcasting at a frequency similar to your router. Looking into exact fixes at the moment.
I have no problem with wifi and multi touch.
But I noticed that two fingers cannot be very closely touched it will mingle together. For example if you hold shift button on keyboard it could act like normal shift (turn lowercase to upper or vice versa) but its very difficult to use shift + a
Also lots of games exiting on me, first I thought was multi touch acting up so I could accidentally hit home or back button. But then I think its just matter or compatibility of those games with ICS.

do you know if the latest update solved the touch problem?
Same issues here. On the samung version (dont remember the codename) i had this issue so i rooted and changed it so that google updates my phone. But this didn't help either. Still losing wifi when i am downloading. Like now i was going to download 9mm and after 2 seconds the wifi disconnect until i quit 9mm and then it pops up straight away. Can it be a hardware issue?
PS: before i change my phone brand to google, i could see the "avoid poor wifi connection" but now when i go to advanced tab it's gone :S
Ok everytime i try to test wifi in speedtest it says network communication issues after 2 sec of testing. Any info please? Do i have a faulty unit? going crazy over here
For what it's worth, I haven't had either of these problems on my Galaxy Nexus, and it's been on a lot of WiFi networks.
I've gotten speeds in excess of 20mbit/20mbit via the speedtest.net app multiple times on the campus wifi, as well as my parents', and my dorm connections. I've downloaded the Asphalt files twice without any interruptions either time, and I've never experienced any problems.
As for multitouch - no problems with that either. To type in all caps you can hold down the caps button on the keyboard and type - it's never given me any issues. I don't think I've been in a situation where I've felt multitouch hasn't performed right.

Multiple ROMs doesn't mean much, they all share official driver binaries and radios that are available.

a5 2017 wifi problems

I am getting really bad wifi connections and the phone is very slow at browsing refusing to load pages fully. Running Speedtest by Okla says "network communication issues". I get this problem on wifi in public areas and at home. It does not seem consistent. I got so fed up I factory reset the phone. I connected to another wifi router at home and so far everything seems fine. All other devices work fine with public wifi and wifi router at home including Samsung J5 and S4. Any ideas?
Stock rom? Orginal?

I have sometimes wifi is reconnecting, but most of the time I have a good connection.
I'm having weak wifi reception with the A5. When placed side by side with S4 and S7, the A5 has the weakest wifi signals. Speedtest confirms this as well.
Yeah, definitley weaker reception, i compared to my Htc 820 and Sony m2 aqua and it was pretty weaker all of them are on stock roms.
Well, me too. Weak reception when just a littel away from the router. Randomly loses signal force, can't see any router, then, connect again... It seems to get worse when heavy using internet, like watching YouTube videos... But near the router, everything stays normal... My moto g 2014 never had the problem and I'm in stock rom too...
It strangely seems to be YouTube app who causes problems, because when I stop watching videos the signal force get actually more stable, even full in places it doesn't get full when watching YouTube...
But it still seems to suffer from some instability at its natural... When I tap play in youtube, the signal drops to almost zero...
I would like to know what is happening, because it isn't a cheap phone, and even moto g 2014 has got a better wifi
It also seems that demanding wifi in general causes signal to get weaker... I never saw something like that, signal strength doesn't get affected by use, only bandwidth...
Any other experience?
Similar issue with my A5
I recently bought an A5 2017 aswell and my phone also has HORRENDOUS wifi , not just that but for some reason it would randomly stop reconnecting and stop showing the wifi router or anything and the wifi connectivity doesnt turn on , and then if restart it but it would hang mid restart and then id have to hard reset it by holding the power and volume-down button , and this whole procedure happens like once or twice a day so ita really frustrating. Especially because this is a New phone btw, my wifi is perfe fly fine because i ha ve other technology and have previously used many huawei phones which have perfect connectivity and this was my first experience with Samsung, any help would be much appreciated thankyou !!
I am having the same issue as the person above. Pages will refuse to load until i turn off wifi or refresh the page. There are duplicate posts coming up on facebook. Like 4 or 5 posts repeated before new ones. Twitch constantly buffering. Tried on mine and parents wifi with same result. Both were always and still are fine on my note 4. I have 2 weeks to return it to o2 if its faulty or is it just a phone with bad wifi in general?
Edit: i think the facebook thing might be a facebook issue as its happening on my note 4 too but everything else is specific to my a5.

Android 9 Issues (Persistent)

I've been facing issues on my Mi A2 Lite ever since the Pie update in December. These issues have been persistent on my WiFi and it has gotten to a point where I'm inclined to change my phone. Keep in mind that the same WiFi works fine everywhere else. Here are the issues:
1. Browsing
I've tried a few browsers but the issue is on all of them. What happens is that the first couple of searches are normal but after that the page is stuck on loading and maybe after 10-20 minutes it might open that page. The error 'Bad network connection. please wait' pops up everytime this happens
2. Facebook
It literally doesn't run. Newsfeed stays the same, comments can't be loaded, groups can't be visited etc. It acts like my WiFi isn't turned on even though it is.
3. WhatsApp
Messages work fine but if I try to send a picture or video to somebody it never goes through.
4. Twitter
Twitter and Facebook have the same issue. Sometimes when I'm using it on mobile data and switch back to WiFi it works fine but that is not very often and doesn't last for too long.
All these issues happen both when the WiFi and Bluetooth is turned on and when only WiFi is turned on. None of these issues happen on mobile data. And the same WiFi works fine on other devices like I have said before.
Has anybody faced this issue? Is there any solution (I have tried pretty much everything)?

Nobody!
Try To Factory Reset!
Yes wifi + Bluetooth issues... I don't know if this has been fixed I have given up on January
Personally didn't see all the issues you describe, but I will concur the WiFi is wonky at times. Even seems like the signal strength is weakened by stock ROM.
I was on the last security patch recently and was trying to watch YouTube on a public WiFi and nothing was loading, thought maybe there was a restriction as switching to VPN connection I was able to view no problem.
I recently switched to paranoid android and WiFi signal is noticeably stronger, and on the same network I was having issues, YouTube plays fine now. I am only a couple days into using PA, but my opinion is it is preforming much better than xiaomi releases.

WiFi issue in Moto One Action

Anyone experiencing WiFi issues with their One Action?
I am getting only around 15mbps on WiFi while my other phones are getting 45mbps+ on the same WiFi.
After phone reboot, I get full speed for a couple of minutes and then back to around 15mbps. Dunno if this is a software issue or hardware issue.
Please anyone can confirm if they have the same issue. (My phone is on the latest Android 10 update with June security patch)
You are not alone. It’s a known software issue with certain wifi routers. Personally,I didn’t experience any issues with my particular router, but many people do with other routers (for example Fritzbox).
Thanks for reply.
So that means my phone is not the problem?
Are there any fixes for the problem (or what this problem is called so I can look for solutions)?
In my case WiFi 2.4GHz is slow. Connecting to same router but with 5GHz band and everything seems fine.

I fixed by using a TP-Link extender. The speeds are normal now.
Edit: Many users are reporting this problem after the Android 10 update. If you are experiencing this problem too then please keep telling the support this problem via email.
The phone is compatible with some routers and gives bad speeds on other routers after the Android 10 update.
