Wifi Constantly dropping - Samsung Galaxy A21s Questions & Answers

Multiple times a day the wifi connection will drop out of nowhere. It won't reconnect on its own, but if I turn wifi off and then on again, the connection will be fine. So the connection/signal strength is fine. Also, I've had the phone for about a year and this only recently started. To add to that, I think there might have been a recent firmware update around the time this started, but I'm not 100% sure about that. Anyway, I've tried so many different solutions at this point, but nothing has worked, so I'm hoping someone here knows what's going on or what can be done to fix it.

DCD 3.0.1 WiFi Issue

Hey guys..
WiFi was working for me at first, but now my phone pretends like it doesn't even have WiFi. Any way to fix this without reflashing/hard resetting my phone? I tried the uninstallation of WMWiFiRouter, and it still didn't help. Can I somehow revert back to a different driver without having to start over again? Thanks!
can you elaborate on teh issue a little bit? im also having a wifi problem, but havent found many others with the same issue. i want to know if yours is the same.
sounds like a wmwifirouter issue to me.
i dont think so. i have removed wmwifirouter from mine and still have the problem. it works once in a while, specifically after a soft reset.
I don't know what else to say. Turning on the WiFi switch does nothing, pressing the WiFi in Comm Manager does nothing, and I no longer have WiFi under Connections. I see Wireless LAN, but not WiFi. My Wireless Today Plug-In only shows Bluetooth and not WiFi anymore.
All in all, I guess it seems like my phone doesn't realize that I have WiFi.
I just upgraded to DCD 3.0.1 yesterday.
WiFi is still working for me (WPA-PSK, AES encryption). I'll test at work tomorrow.

I've never used WiFi Router and I get the issue on soft resets and usually when I someplace where coverage is spotty.
I seem to be having an opposite problem. My WiFi randomly activates while I am in a call.

ive seen that thread, and that problem, but mine at least, is different. ive done extensive testing and my problem doesnt ahve anything to do with wmwifirouter. the problem started before i ever installed it. and its not that it doesnt work, it just works sporatically. usually after a soft reset, its ok. until i turn off the wifi switch, or push the power button. then its like theres no networks...but there definitely are. i thought the problem was specific to me, but now that im seeing other people with the problem im starting to neglect my previous theories that only pertained to my situation, in favor of no explanation.
just wondering. the other people with wifi problems. what carriers are you guys?
im on vzw
thanks
Happens on my Sprint Mogul, and I have tried that fix in the thread.
Im on Sprint and I keep having the same problem with my wifi.... this all began when i upgraded to the 2.2.6 rom i believe. I used to not be able to get wifi, then after a few days it would suddenly read my network but it wouldnt connect. now after upgrading to 3.0.1 it reads the network fine but it and tries to connect but either it disconnects instantly after it connects or it never connects.
Ive never had wmwrouter installed and my network connection security is WEP 128.
Any ideas?
wifi problem
I have the exact same problem with my phone...started about a month ago. Upgrade to new rom (from 2.17) didn't fix it....
sorry you guys are having problems, but i am a little relieved to see that other people are having the same problem as i am.
my one question, is are you guys sporadically seeing the wifi work fine. mine does, usually after a soft reset for a little while sometimes, but once it "clicks off" it is gone until after a soft reset.
thanks
I have the wifi issue as well. I am running DCD's 3.0.1 ROM. I also have the WMWifiRouter program installed. In my case, the WMWifirouter program would run and my laptop will pick it up but then I can't connect to it. It also seems sporadic. My laptop will show full signal of the program then when I hit refresh the signal will disappear. With the wifi switch, when I turn it on the wifi icon at the top comes on and act as if it is searching for wifi signal but it would never connect to anything. Even when I am in a wifi hotspot my phone would not pick anything up at all. *NOTE: Even before I upgraded my ROM, I started to have wifi problems on my stock 2.08 sprint ROM.
yea it sporadically works for a short period of time but once it disconnects it won't work again.
Sometimes it finds the wireless network and sometimes it wont find anything. Its kinda random.
Since I was having an issue for GPS to take a while to lock on on top of this WiFi issue, I just decided to flash the stock Sprint ROM 3.35 and then reflash DCD 3.0.1. Everything is working beautifully now.
it is this app
ok then test it on a phone that has had it an another one that has not! remember that once its on there you will find that it may never go away even if you flash, i been ther buddy
dont for get to change the routers name so you don't be dumb about it mmmkkaaayy.

WI-FI Issue
Are you connected to your PC while trying the WI-FI?

Wifi Periodically Dropping out

Ive searched the forums, googled, factory reset, messed about with *#0011# power save, rebooted/forgot router and I'm STILL having issues with the wifi dropping and reconnecting periodically (maybe once every 10/20 mins?) . Im on BLG8 which is as far as i can tell the latest firmware (im not rooted) for the UK.
Has anyone got a solution to this? The main reason is I use Skype a lot and the call will just drop (obviously) with the wifi drop outs.
No other device has issues with my wifi router.
Any help would be much appreciated
Cheers
Does it make any difference how far you are from the router? Does it always connect fine initially?
I'm having the same issue and i've tried every fix that has been suggested. I dont understand after spending the amount of money i did on this phone that i have to run through the dialer to get it to work properly sometimes. Then other times it still drops out and wont come back on for 5 to 10 minutes. I've changed roms, kernels, and wiped completely i dont know how many times and went back to stock. Still works sometimes and hangs up others. There doesn't seem to be a permanent fix for people lucky enough to have this issue still. My 30 day return is way up and gone so i cant send it back. Samsung cant seem to give me an answer. I'm at a loss for words.

My 30 days was up, it's still been replaced under warranty. I took it to CPW who sent it away, it came back 'fixed' so I asked them to log into their WiFi... of course, they couldn't and the guy said he would order me a new phone but it would need to come from Samsung. My new one has blazing fast WiFi!
i have the same problem. i was hoping a new rom would fix it, but FWIR its busted. i get 2 bars MAX no matter how far i am from teh router. its fast enough, but it drops out constantly.
also my screen is sometimes slow to turn on from sleep.
im on vodaphone if that makes any difference.
Guys... I had a very similar problem with my phone.
First of all WiFi became very unreliable.. like yours. I changed ROM and it still persisted. I even went completely back to stock.. and it still persisted. Dropping out.. no reliable connection etc etc.
Then it started being really weird.. the touchscreen started responding intermittently. Sometimes I couldn't get it to unlock. And this was all on stock.. no root etc.
I was ready to send it back to be repaired.. and I came to the conclusion that there must be something staying the same.. even after a wipe / reflash. Maybe one of the other partitions was corrupt???
Now I'm not clever enough to investigate.. but I did come to the conclusion that a repartition may wipe everything and make it a real fresh install next time.
So I found an appropriate .pit file and stock ROM and used Odin to flash the ROM and partition the phone.
And it is now all fully functioning again.. no WiFi issues at all.

It seems to have improved with the latest JB leak, still every now and then but certainly better - i did a full factory reset + cache wipe in stock recovery (im unrooted etc). Still, would a modified kernel/modem fix this very common issue?
This problem is everywhere it seems.
OK so really weird update: my screen unlock is still a bit slow, but my wifi hasnt dropped for a few hours. i went through all the vodafone crap and updated/ran/configured it all, and now it seems fine. seemed vodafone wanted to verify my phone+sim details but couldnt over the wifi so kept trying to do it over the 3g, but couldnt do it quickly enough so the wifi cut it back out again. I have a headphone amplifier that is very sensitive to mobile phone signals. it beeps 4 seconds before i get a message or phonecall, and "ticked" at me whenever my wifi dropped out. its not ticked in hours.
TL;DR anyone on vodafone, run your "my vodafone" application and configure it all. might fix it.
Mine drops wireless a lot when connected to wireless A networks. It seems stable on wireless N networks. Anyone else notice A networks to be worse?

WiFi Issues

So, I've only had my LGOG for a day and a half and I am having issues connecting with WiFi. At first it worked fine but when I left the coverage area and return a few hours later it would not connect. Tried turning off the WiFi but it kept turning itself back on. I reboot the phone and it works fine as soon as it boots up it connects the WiFi no problem. It is my work WiFi and I had no issues connecting to it from either my iPad nor my HTC One X that will soon find it's way to eBay thanks to this beautiful LGOG. If no one else is having issues, I will call AT&T and have them switch it out. I just wish there was an easy way to back up everything, I mean my home screens and app locations exc. It takes so long to set everything back up the way I find most useful.
WiFi on my device has been excellent.

The Wifi performance of this device is unbelievable. I get the best speeds I have ever seen with any device including PCs. It's either a faulty device or maybe your work has strange security settings?
I had this same problem with my LGOG and my home wireless network. It just would sit and try to connect until I rebooted the phone.
That was on stock though. I have not had any more problems with it after flashing the base rom.
My work has standard WPA settings and it was connected fine yesterday. I left again during lunch and when I came back, same problem and had to reboot the phone. AT&T is sending me another one already and a free case. Can't be too mad about it I guess and at least the phone reboots fast.
Have you tried using the ATT smart wifi app? Fixed the exact same issue for me.

I haven't had any issues connecting to wifi, but I've noticed the status bar icon showing low signal even though it's actually maximum signal.

Twice My O.G. wouldn't connect to wifi networks even though it had connected to them in the past. I tried to turn it off and on and scan for the network that I am in range of and it wont show any networks it just says "not in range" when I am in range. So to remedy the situation I turned the phone off and then on. It has only done this to me twice but it's a real nuisance because both times I needed wifi. My phone is stock.
You're in a minority. This thing's wifi blows most other wifi implementations out of the water.

Perhaps you need to swap out your phone

I wish my wifi would stop re-enabling itself. It's chewing up my home bandwidth.
I have been having this issue as of late. It seems to have developed this habit in the last week or so. At first I thought it was Time Warner trolling me but it started happening at work. Something tells me it has something to do with the stock At&T Rom putting the wi-fi radio to sleep and not being able to bring it back online. Reboot fixes it most of the time but sometimes it takes a couple attempts. I have been hesitant to mod this phone still because I would really like to see CM working well before I flash. Also my instinct tells me another possible culprit could be IPv6 on certain routers. That, however, is far less likely unless someone with a decrapified Rom has experienced this issue as it would be a cross platform issue in this case. Anyone else have any insight? Otherwise it's time to get rid of the Att rom.

Same issue here. This is my second LGOG and have been happy with both except for some minor glitches on both with the keyboard freezing up as well as with the WiFi not re-connecting after leaving the area. A restart normally fixed both problems. My first one bricked after rooting and removing all of the bloatware (the phone checks for certain apps upon booting to keep you from removing stock apps). Tried a fix but I couldn't get a Rom at that point as the phone had been out on the market for under a week. I haven't messed with it since but I may try a new Rom and be able to fix the WiFi and get rid of all the bloatware that way.
Just got this ROM running today. No more WiFi issues at all. Some minor ui bugs I am OK with.

Seems like, as usual, At&T bloat ware is the culprit. I experienced the same on my Aria and Inspire. Hope this helps and good luck.
Also I had the keyboard problem but that went away when I switched to the Android default keyboard. One of the other reasons I decided to root was because rather than freezing, the Android default keyboard started typing then the auto correct broke and stopped displaying the words unless you touched the area you were typing in. It really bugged me when it started doing it right after I factory reset. Weird huh?

LG Optimus G Wi-Fi Receiver Disconnect Issue
Funny...I've had some weird home wi-fi issues on two of these.
To explain, I bought mine in December, stock OS of course, and immediately noticed it turning off my wi-fi every time I tried switching between the two home wi-fi SSIDs I created when I upgraded to DD-WRT. This also occurred outside my house, but stopped shortly after the nearly-immediate Android OS upgrade came over (and forced me to install it, I might also note; I'd read the thing was just more AT&T bloatware, but two or three boots later, apparently I got no choice, and it auto-installed).
The good news was, somehow, this 'update' somehow stopped the thing from turning the wi-fi off when I switched between IDs (my base router has a 5G 2nd network which I wanna use when I'm around it, but DD-WRT won't support, as far as expanding it--thusly, I have another 2.4GHz signal I use and relay out around my yard).
That bad news is, though, that I screwed up the phone with the Root Toolbox (Lite) by merely fiddling with their bootanim settings on that original phone. And I mean bricked it, solid.
I'd never bricked any phone, so this ticked me off. Luckily, I was still within 2 days of my 30-Day Best Buy in-store replacement warranty, so I took it back, they fiddled too, and gave up on it.
Hence, my 2nd phone...which now, even after the system update direct from AT&T, still turns off my wi-fi every time I try switching to that 2nd SSID, so I'm left wondering if it was even the same update; I don't think I did anything else, and can't see it as a settings issue, because it did it right out of the box, and the first one stopped after the only system update before I got a chance to even figure ANY user settings out, much less any network ones.
So, now I'm 'going shopping' for 'some PlayStore app' that will skip this B.S. and automatically connect to the strongest home wi-fi signal (within reason--sometimes they're equally strong), without obnoxiously turning off my wi-fi receiver as I look at it.
This kind of malarky could spoil some phones for some people, but I'll struggle along due to the speedy quad-core in it [sigh...wah!].
I guess I'm a big baby, seeing as how I don't write one iota of code, but my personal haughty view is that any dedicated wi-fi devices should have better wi-fi connection than any Windows OS made...and, so far, this'n doesN'T!
What a dumb thing to let happen in such a potentially awesome phone...[AT&T!!!]
This might work or not but can't hurt to try. Apparently some people in the new snowleopard JB thread was having similar issues and for a few, changing the security from WPA2 to WEP worked. Although mines been good and fine on WPA2 but worth a try.
Using wep in 2013 is beyond retarded.

DUDE! Senior Members here can be a little uppity and rude...even if they're completely correct.
Glad you called out the 'behavior', and not the 'member', though...
but enough of the technicalities...I'm still looking for solutions...beyond blaming AT&T (too easy), or even the strangeness of getting into blaming some weird kind of manufacturing errors (QC at best), I'm left waiting for a substantial OS update (like, oh a better place of decimal, perhaps?), or worse, an app...anyone look at the state (and sheer number) of 'wi-fi' apps? Anybody here can guess, they number in the thousands, and a Play search for 'wi-fi' gets you astronomically different results from 'wifi', even, so I'm not sure I need to be looking at that.
Maybe it's even somehow that, with the first phone, I noticed this, and somehow added my own home network to the AT&T Smart Wi-Fi 'bloatware' that came with the phone (not the worst evil they've ever done, so far, BTW--it does exactly what I imagined should be going on in the background while you're driving around, indexing locales with free Wi-Fi for you to choose to save later...an idea I would call 'Tarzaning', if you get my drift).
I'm gonna try changing two settings in the AT&T 'Smart Wi-Fi' bloatware to 'My Spots' temporarily, at least, to see if it'll latch onto my home stuff more aggressively. I just can't wait to report back my fantastically successful findings here (right after I buy the domain name 'snarkasm.net').
Oh crap...it's already taken.
Is the AT&T smart wifi thing enabled by default? I can't remember. I thought it sounded useful so I played with it a bit but ultimately I didn't like the way it worked so I disabled it.
Still wanted some way to auto-enable/disable wifi. I didn't have anything to go on, but I picked up "Smart WiFi Toggler" which seems to work well. It uses location-based rules (based on cell signals) by default. I also use AutomateIt to turn off mobile data once wifi has been on for 1 minute, and turn on mobile data immediately when wifi disconnects. I have no idea if this saves me any battery life, but I do it anyway.

[Q] Wifi woes

Hey guys I need some help with my Z2, I've had wifi issues on my phone for a while now with it constantly getting low speeds and random disconnects even when showing 2 or 3 bars of signal. I've tried it on multiple routers on multiple providers and the results have been the same, I've tried editing the router settings including changing the channels, the ghz from 2.4 to 5 and changing the security from wpa to wpa2. I never use stamina mode, or minimize battery usage on battery saving feature when using wifi so it's not that. I've tried factory resetting the phone and using the pc companion to reinstall the software version and that made no difference, I've even sent it back to Sony repair twice, the first time they factory reset the device which was pointless as I'd already done that myself and the second time they swapped out the wifi card and it was ok for a few hours but it soon started slowing down again, I spoke to a Sony rep today and he booked it in for repair again but I'm worried they're just going to fob it off again. He did say that one of my apps may be corrupt but again I haven't noticed anything out of the ordinary with them or any unusual behavior with the phone apart from the wifi, not sure if there's a way I can find if any of my apps are corrupt apart from factory resetting the device and not installing any new ones for a couple of days but even that wouldn't pinpoint which one if any were corrupted. I would just send it back to Sony but at this point I'm not sure whether they can actually find out what it is and I don't want them to just keep sending me the same broken phone back. Anyone have any idea what the issue could be or what i should do so I can stop pulling my hair out and actually start enjoying this device? Thanks for any help in advance

Serious Wifi Connectivity Problem (Please help I'm dying)

so i have this problem for about 3 months now,
so I'll explain the problem I am facing,
I'm connected to wifi unless I'm an inch close to the router, so if I go away, the connection will be disconnected, however, in my work, I am connected to an access point which has put a big smile to my face, but apparently when I went back home, I faced the problem again, and I guess I would be connected to that only access point, which is the first time I've seen since i got this problem, all the routers/modems I tried to connect was a failure(saved, secured) since my phone met this access point.
I already tried Factory Reset, Flashing custom modem, *#0011#, deleting data/misc/wifi, changing settings on router and many many more as I've put an hour of fixing this every single day. none of this works. for what I recall, all I did was download an GPS app(I don't remember what it is) and then poof, wifi is doomed.
I have my iPad and my laptop connected and there's no issue with them, only on this phone.
I'm running 4.3 btw,
does anyone know how to fix this problem? my brain hurts a lot and I don't know what to do. please help I'm dying, thank you
