Really Weird WIFI Problem

Greetings everyone. I've had a T-Mobile Dash (the black one) for quite a while now, but since I got it has a really weird problem with the WIFI. When I turn on the WIFI it searches the connections flawlessly, I can put the key on any connection or enter freely when is open. But then it says connecting and a few seconds later it says connections available again, as if it tried to connect and could not. This happens with ALL connections, unsecured, WEP, ect. I had installed every cooked rom available and also installed the stock one to see if it works, but alas, nothing works. Does anyone has any tips or tricks on how to get the WIFI working?

Have you considered that probably the router your phone is searching has a problem? or you tried in other location and still the same problem?

Thanks for the suggestion, but yeah, I already did that. I have tried connection in many routers and in all happen the same thing. It is a really weird problem and searching through the 3VO thread I saw somebody had the same problem but no answer. I am ready to just accept that my Dash is WIFI less forever. I have tried everything. But thanks anyway

[Q] Sometimes it shows error when open the wifi.

Unless you reset the phone.

Known issue. So known, there's already a bug on it on the tracker but you wouldn't have checked there...

I encountered the problem, too.
It seems when WiFi is switched off and the on in an other location where the SSID it was connected to isn't available.
It seems it tries to connect that SSID then returns error.
Cannot follow your link on tracker...

Wifi not working properly

This is strange, my wifi works but then suddenly it only uploads (only green arrow lights up) and it will not download (orange arrow will not light up). I can disconnect and reconnect and I get some service, but then nothing happens.
I've tried the following:
Rebooting the phone several times
Restarting the router
Changing from DHCP to Static IP
Turning off the new open network notification
Clearing data from Google Play store
Disabled wifi power save with *#0011#
Nothing seems to fix it. What is going on?

READ BEFORE YOU FOLLOW ANY OF MY INSTRUCTIONS!! U HAVE BEEN WARNED I AM NOT RESPONSIBLE IF YOU SOMEHOW DAMAGE YOUR PHONE!!!
OK so let's go straight to Ur answer.... Let it sit for a while after it boots up (a minute) with Ur wifi on. so restart the phone while wifi is on and let it sit for a while... If Ur using a wired connection with a wireless router disconnect the wired modem then the wireless and wait 10 secs and reconnect the wired first and let's all the lights go green or whatever color they show u its ready and then connect the wireless router and try to connect to it.
If that didn't work and you don't have your phone rooted then flash the only time that we have for now. That should fix the wifi issue.
If it doesn't work try to go back to stock and let it sit for a while without touching it and if it doesn't work then the phones defective but keep in mind that if you went through the root process that if you send it back without erasing the flash counter your warranty will be voided so be aware of it. I don't know if there's an app compatible with the s4 so if it's not rooted then replace it just to be safe.... It's your choice

My phone is not rooted.
What did you mean by flashing the time?
How do I erase the flash count if I decide to root later?
Thank you for your help. =)
------edit------
The method -- sans the flashing the time -- seemed to work, but then the internet stalled again. This is happening on two S4 phones. My other phones have no trouble with the wifi, my pcs have no trouble with the wifi. What are the odds that two phones aren't working? Nobody else is having this problem?

I have already made a thread with the sane issue. You're not the only one facing it. A lot more people are too. It might be a software thing and might be fixed in the next update. If not, exchange it

What router are you using? D-Link DIR-655 seems to be most popular one people are having trouble with. What mode are you using (a/b/g/n/mixed/etc)? Mine only works with Mixed n and g mode. When you turn off the wifi, does it actually turn off (the green indicator will dim but should actually go away when it's off)? The stock rom seems to want to keep the wifi on at all costs... not sure why! Mine is very stubborn and takes several tries before it actually turns off and says "turn wifi on the see available networks." In order for the *#0011# Power Save Mode Off setting to work, the WiFi needs to actually turn off then back on. I have to toggle airplane mode sometimes just to get the wifi to turn off.

DGL-4500 Linksys
It shuts off when I save; I put the settings as you suggested. I'll test it.

DGL-4500 is a D-Link, correct? If it is a D-Link, I'd make sure you are on the latest firmware for it and try various mode settings (disable mixed modes, 2.4GHz or 5GHz only, WPA2/TKIP only, etc). This post details a solution to my scenario; maybe it'll give you some ideas.

I have d-link router too and wifi working just fine

Yeah, it is a D-Link; not a Linksys. I tried what you did, it seems to be okay so far. I have the latest firmware. I still think this is a problem with the phone. Do you think an update will fix it?

Yes, it's definitely a problem with the phone. I've spent the last several days researching and trying to find a permanent solution. It appears to be a software issue but I've yet to explain how wifi works just fine for some and not for others.

Any solution to this yet without messing with the router setting. I have this week left to get a full refund. I doubt exchanging it would make a difference. Plus tmobile is out of stock and stores won't allow exchanges since I bought mine online.

I sent my phone to Samsung, so I'm waiting to hear back from them on what they have to do to fix my issue. Maybe it's a faulty batch of Broadcom chips?

Thanks for the reply. Hopefully it can be fixed. I have 4 days left to return so I will return it for now and buy it later if it gets fixed. Let us know how it goes.

Has anyone heard anything on this? I got a PM from Samsung asking me some questions, but they never got back to me. Any news?

[Q] Major WiFi issue out of nowhere?

Hey all. I need some advice. This morning my G3 (D850) dropped WiFi connection for no reason. It says the signal is good but the network info says saved, secured. It will attempt to connect over and over again and if it does connect the signal is weak as can be and it drops the connection within 2 seconds. My coworker has a G3 also and is connected to the same work network I am. His connection says excellent where as mine said good. His device connects just fine with full bars. I'm baffled. I've already tried manually selecting 2.4 Ghz and 5 Ghz instead of auto select and that didn't help at all. I've tried manually turning off WiFi and turning it back on. I've tried turning airplane mode on and then off to refresh the connection and that didn't help. I've done a battery pull as someone in one of the android authority forums suggested that (apparently I am not the only one having this issue.), didn't work. I've unchecked WiFi optimization - no dice. There was another post on a different forum here on XDA that said turning off WiFi and then deleting the WiFi config folder located in data/etc/wifi and then rebooting fixed the issue for them so I tried that. After reboot when I tried to turn on WiFi my G3 rebooted itself. Does it everytime. SO, I had to restore to a nandroid backup (btw I'm on rooted stock 10f) to get the phone to stop hating my WiFi toggle attempts. Last ditch effort I did a factory reset hoping for an easy fix... Nope. I don't know what else to try. It was fine yesterday all day. This morning it was perfectly fine and then randomly started having this issue. I haven't altered any system files whatsoever. I really don't want to send my device to LG for warranty replacement so I'm hoping someone can help me out that may have had this issue and resolved it. The only difference between my device and my coworkers device is he is still on 10d and I am on 10f. That could be the issue I guess but that doesn't really explain why my device has been perfectly fine until this morning and I've been on rooted 10f for weeks. I am planning on flashing back to straight bone factory stock 10d when I get home here in a few hours from work but Idk if that will help or not. Judging from the amount of google search results of "LG G3 WiFi connection problems" this seems to be an issue for several people. I won't know if it's on the software side or hardware side until I get home but in the meantime has anyone had these issues at all? People have had success in changing to Static IP but I would have to do that for every connection I attempt to connect to and that's a pain in the a$$. Also, that does nothing to identify the root cause of the issue. Any help would be greatly appreciated. =)

Thanks for the reply. So it turned out my phone just randomly decided it doesn't like my work network anymore. Idk why lol. I got home and it hooked right into WiFi. Gf's WiFi and open networks as well. I call shenanigans. I went ahead and flashed back to 10d anyway though.

I am having the same issue! But it is happening in other networks too...sometimes I get the phone to connect but it only works for a while and when I check the networks it only says Saved, even if I try to connect again

Having the same issue, whether at work or home, my wifi has become near useless. I've even gone as far as trying a different ROM. Didn't work.

Same thing here

I also have tried factory reset, installed a new ROM, changed settings in my router... but the problem remains I don't know what to do anymore, I use wifi a lot!! I searched through other topics but no one seem to know how to solve it. Unfortunately my warranty already expired, I took my phone to some technicians but honestly it didn't help at all...they all said it was a software bug and I should wait for an update but if it was just that a new ROM would fix it,right?
I am not very familiar with phone hardware but I assume that if it was a hardware problem I wouldn't be able to turn it on or connect to any network, right?? (any experts here???)
Any solution is welcomed.

anyone please?? :crying:
P.S : I tried a new baseband, new kernel and new ROMs. So far, nothing changed.
I can connect sometimes but get kicked out within minutes. At other times I only get the saved,secured message.
This is happening in every network

[A5 2017] Internet may not be available

Hi guys,
I have a problem that when my A5 tried to connect to the wifi, the wifi logo with exclamation mark (!) shows, and later shows a message "Internet may not be available". There also two options below, to stay connected to wifi or disconnect it.
I have tried to restart the phone, wipe the cache, and finally I factory resetted it but it stays the same.
Any fixes? Is this a software problem?
Thanks in advance

Exact same issue, been trying everything I saw on internet for a whole month, including flashing a new firmware and other possible solutions that led to root the phone with no result...
I managed to capture logs (using adb shell to check dmesg and logcat) concerning what seems to be the cause of the issue:
When I turn on the wifi switch, the logs say "Wifi driver unloaded" and "Wifi driver loaded with scan capabilities only".
¿Could you try to capture logs and post them here so I can check if we are facing the same?
Seems I'm gonna stick to my faithful Moto G4 Plus a bit longer until I sort this out.

I have same issue with my a3 and sm-t810. what solves it for me is just turn of wifi and turn on wifi. wifi reconnectes and further no issue. both devices on 7.0.

My wife's and my phones have recently started exhibiting this very annoying problem. The only permanent fix I can find is to give each affected device a fixed IP address. If you do that, though, you really ought to log on to your router and permanently reserve any IP addresses you intend to use. None of this ought to be necessary, though. Android developers, please fix this very annoying bug.

Assign a fixed ip address to the phone and other devices seems to work for the moment.

Had that issue too, have a dual band router and assigned different ssid to 2.4 and 5 ghz.
No more issues since...
