Please help me troubleshoot my wifi problem!

Fresh flash of WM 6.5 over radio 3.42.50 on a Titan. Under Network Management, I've selected that "Programs that automatically connect to the internet should connect using:" My Work Network, since I don't have a data plan. I go to Wifi settings, select Add New, put in the ssid, click through the security settings (temporarily disabled for this test purpose). My network shows up as "Unavailable". (I'm standing right next to the router). I click "Connect", it says "Connecting" for a couple of seconds and then goes back to "Unavailable".
What should I check first? I'm at my wits end.

You shouldn't have to "add new", your ssid should be automatically discovered and displayed in the list of wifi networks.
Did you connect to a wifi with your phone before, or is it a first attempt ?

Yes, I'd been connecting just fine until a few weeks ago. In fact, the refusal to connect was what prompted me to flash the thing -- figured that starting over might help.

So, your wifi connection was working well, but suddenly, for some obscure reason, it stopped working. Therefore, you decided to reflash your phone, but it didn't help, still not working.
Is that correct ?

I know I sound like a complete doofus, but yes, that's basically it. The weirdest thing is that every once in a while it'll find a wireless network and connect. But the connection never lasts for more than a few minutes, and then when it's gone the network is "Unavailable". And to anticipate your next question: There doesn't seem to be any rhyme or reason for when it works. At this point I'm thinking I'll pick up a used Titan or Vogue on eBay and junk this thing.

Did you try a different rom ? Could be a faulty rom.

I've tried several different roms, yes.

this happens in some roms...

[Q] Problem with wifi Samsung Galaxy 5 (i5500)

Hi, I've some problem with wifi connections. I own a lynksis wag54g2 wifi router. I can establish a connection, but after some times (it's not standard, it may vary), my device disconnect from the router and it's not able to reconnect. All that i can do is plug off my router (i take off the ac adapter) and when it's up again my phone can connect. it's very frustating, but i don't know what to do? i've tried setting something in wifi preferences' on my phone but nothing change. i've also flashed my firmware to the new one, hoping that it could fix that problem, but it didn't. someone could help me?

you can update the firmware to a newer one. this would fix your problem.

Hello.
I have a problem with WIFI on Galaxy 5 (i5500)(Europa) too. They have already changed my phone with new one, but the issue remains. So, for the second time now, I was able to connect my phone to my router for the first time, but after the first interruption or disconnection of WIFI I could not access to wifi anymore.
When I enable wifi in the phone starts ''connecting'' but then reports ''interrupted'' eventhough the signal is recognised as strong.
Firmwire version is the latest available. Router is encrypted with WPA2. Also I can access to router with my HTC Tattoo (Click).
Does anyone know the solution?
I have a decision to make(today), becouse If there is no solution to this I will change to another phone as I still can (Galaxy Spica).
Advise please.
Thanks a lot

What router do you have? have you tried with any other wifi network? i said that because my have this problem only with my router, and not for example with my girlfriend's one.
I found a little fix for my router, linksys wag54g2: open up the config page (192.168.1.1), go for wireless tab, select protection page and click on save settings. that reload the router and my phone is able to connect again.

Hi.
Thanks for your advice. There is some problem with router.. When I restart router the wifi on the phone works until swiched off or interruption becouse being out of range. When I try to connect to wifi again does not work unless I restart router again. ..catchy.. Interfering with mobile connection also makes the drop of wireless connection on my computer, so I need to restart router. I don't know the permanent solution. If anyone has any idea how repair this forever please let me know.
Best,
Thanks

Hi,
Here is my problem with my wifi with the galaxy 550.
For security reasons, my wifi network can't be detected (invisible). If i want to connect a new device by wifi, I must first set my wifi visible and then register my device.
Then I set my wifi as invisible again and the device can connect automaticaly to my network without "seeing" my wifi network.
Problem is that once i set my wifi as invisible again, my galaxy fail to connect because the network is unvisible.
Is there anyway to fix this ?

I have just read similar post on another thread and replied find it here
I ahvent installed anything, perhaps its to do with the handset if its locked to a particular carrier? just a guess and a question...
cheers

I have an answer! Hope it works for you.
My provider gave me really easy solution for wifi connection not connecting even though it was my own network with all the right info. It worked great the first time, then for some reason the phone locked in the "off" position. So I removed the battery to reboot (later learned the right way by pushing the volume button on the left and the power button at the same time)
Anyway, try this....
turn phone off - remove battery - remove sim card - wait a few minutes - reassemble - then the network should log on with no problem.....Good luck!

No longer detects my hidden WLAN unless I reboot

Does anyone else have this problem?
My home WLAN is hidden, it doesn't broadcast it's SSID. I've never had a problem until maybe the last week. Now my phone won't connect to my WLAN (or any other hidden WLAN that I had connected) until I reboot my phone. Once I reboot BAM it connects right away.
In all likelihood it might have something to do with my custom rom. Guess I should get cracking on a v3 with the latest OTA anyway...

I had this exact same issue a while back I while using a flipz rom.. one version of flipz it connected to my hidden network no problem the next minute it refused to connect I never got an answer so I just gave up
hopefully someone can shed some light on this because it has been bothering me for a very long time

I don't know about routers that have WLAN configured on hidden mode, but don't you guys have an internet provider service for your home and could maybe work if you tried looking for your/their router provided Homepage Login details on Connections/Frequencies/Settings? I don't know much to say but this is maybe an idea, because I had a router with SBCGlobal Internet Services from AT&T on my home lines and we have the top tier DSL service including hidden lines for using the internet as in internet ip addresses, so I'm just saying I could connect with the key included but I don't necessarily have your problem per say, maybe it could be the router or WLAN itself to be reset settings on it for a reboot maybe and it might work, maybe not.
Sorry if my reply fails. I thought of this upon thinking from myself in my head.

I use my own router, not something provided from the ISP. The same thing happened with my father's router over the Thanksgiving holiday. I connected to his network fine after I configured it, but the next time it wouldn't detect it. It's definitely the phone. Guess Jiminy v2 isn't perfect Back to the drawing board!

[Q] WIFI not working anymore.

Hi guys.
first my wifi became unreliable, it disconnected, didn´t reconnect sometimes etc...
now, it´s not working anymore at all.
when i go to wi-fi settings it says turning on, then the red arrow appears, then immediately it says turning off. down there comes a message "unable to scan for networks"
i searched the whole forum, but didn´t find a simlar problem.
i reseted it to factory, didn´t help.
it can´t be a router problem, ´cause all the other devices on the wifi work, even my friends myt4G.
any tricks or ideas anyone?
i got this form a friend in the states, bought last december, he ment, in the US they have mostly only 90 days warranty, in germany we got 2 years.. is this true..?
stock rom. 2.3

Try chaning the channel on your Wifi Router. Most of the new routers you can go to routerlogin.net from a computer that is connected to the router and change the settings. I had the same problem and it appeared all of my neighbors were using the same channels i was. I move to a different one and haven't had a problem since. It will not affect the SSID or the password So all of your login it stuff will stay the same. Any WAN connected device just might lose signal for a second or two while the router changes channels.

thx. channel was on auto. changed it to 11 out of 13. didn´t help. also, i have only 3 wifis in my neighbourhood, i can get with my pc. on the htc, it shows only mine + the direct neighbour..
it seems that wasn´t he prob here...
could it be a hardwareprob? anyone any knowhow on american warranty?
the wi-fi button is almost not responding anymore.. when i turn it off, it turns itself on again, when i go into wifi settings, ist keeps truning on and off again in an endless loop....
edit: tethering does also not work anymore. when i click on portable wif hotspot, it says error...
hardwarefailure?

i found these guys who have the same problems.
http://community.htc.com/na/htc-forums/android/f/101/p/11557/49097.aspx#49097
seems to be a gingerbreadissue... perhaps i´ll try downgrading first.

so i downgraded to 2.2.1 and it worked. got to bed, woke up, not working anymore "unable to scan for networks" again

I do not have the issue, but maybe you can try this.
1. Open phone dialer (Phone App)
2. Dial *#0011#
3. The ServiceMode screen will be open. When it is open. Tap on menu button on top right.
4. Select "WiFi"
5. Find "WiFi Power Save Mode"
6. Press the "ON" button to turn the "WiFi Power Save Mode" off. (It will show as "OFF" if it is off)
7. Your WiFi will be off and on again.
8. Try to reconnect to the Wifi.

You haven't got smart network switch turned on? (under WiFI settings) it'll do that if it thinks you WiFI connection isn't stable.

Set Google public DNS in your router

Ok i just found out its only doing it at home, i tried wifi and my work and it works perfectly doesnt disconnect and connect, but at home it does, though it never did it before and i didnt change or do anything to my router or my phone which i find very strange.
thanks for the help guys i appreciate it a lot, does anyone know what i can do?

have you found a fix to this yet? I'm having the same issue and getting ready to just return the phone and buy something else. My home network is fine, the other tablets, phones, laptops are having 0 issues, Yet my GS5 is either dropping or something, it seems to run horrible slow and things just time out.

No, and the reason that we don't know is that you didn't provide any useful details about your situation.
If you think that someone can do more than make a random guess implies that you think that there are only one or two possible causes. But most issues, including this one, have hundreds of possible causes. So random guesses are not terribly useful. Nor are we psychic, so the only way to efficiently narrow it down is to look for anomolies in your configuration. Which you haven't described.
You should be providing as much technical detail as possible, e.g. what is your home router model & it's firmware version and configuration details, phone firmware version, any specific error messages, any observed pattern, a logcat if you can and anything else that seems relevant.

Have you tried changing the channel on your router?
Sent from my Nexus 7 using Tapatalk

Change the router channel
Change the router SSID
Default the router comfiguration
Change the router operating mode
Update the router firmware
Move the router to a different location
Use a different router
Unplug your neighbours new 50,000 watt pirate radio station
Update your phone firmware
Buy a different phone
Sacrifice a piece of triple chocolate gnocche cake to the pagan God of chocolate and wifi
All random guesses with roughly equivalent (and small) chances of success.
Or one could try troubleshooting the issue methodically.

Hey guys,
I had this problem before, This is an issue with your samsung device and your ISP. They aren't compatible with each other.
Solution:
You must just block clients3.google.com in your modem/router. You can use Block Web Sites section in your modem/router.
Every thing has a solution.
Enjoy your device WIFI.

I have teh same issue on my S5 Cricket. The WIFI does NOT disconnect. Its connected however I don't have internet connection. Turning the WIFI on and OFF fixes the issue, for a short while until it happens again in an hour. Sometimes I slick on a link and wait and wait just to find out the darn WIFI is not connected to the internet. (probably not even connected to my router properly eg, I cant see my laptop shared drives for example).
This has something to do with saving battery or somthing. WIFI internals shut down, even though the icon on top of the screen still shows I'm connected.

Your phone thinks that your WiFi is unstable and dumps the connection to go back to 4g. Why exactly, who knows, but it's easy to turn off the "smart" network switch. Simply hold down the WiFi icon for 2 seconds to get into the connections section. Right there at the top is the smart network switch section ... just uncheck the selection box. Easy.
Lastly, people like fffft need to get over themselves. The fix for the original poster's question was easy, but since fffft didn't know it, he decided to instead attack in order to make himself feel superior. How sad and pathetic does someone have to be to troll forums looking for opportunities to attack and belittle someone else?

The issue is resolved simply by going to the advanced settings in Wifi and disabling 'Always allow scanning'.
Hope this helps.

I had the same issue. I just tried the suggestion, turning of smart network switch in the wifi-advanced menu. Seems to be working so far!
Thanks!

Well I know that Smart Network is turning off wifi.. problem is that i have a fiber at home!! So what kind of problem smart network finds on my broadband?? ?

solution to wifi disconnect problem
I was looking for an answer to a different wi-fi question when I saw this.
I'm on AT&T with my S5.
Under the Wi-Fi settings I have an option for "Smart Network Switch" which says it Automatically switches between Wi-Fi and mobile networks to maintain a stable internet connection. Anytime a computer says it automatically does something for me; I typically say no thanks. I don't typically like my devices making assumptions of what I like, don't like or want to do. So I have that option unchecked. I never have an issue with the network stability once I've connected to a specific wi-fi connection.
Not sure if that will help you all or not. But thought I'd share.
so under Settings --> Quick Settings --> Wi-Fi you will find a check box option named "Smart network switch", untick it, this should take care of the problem.

Same problem
Hi, I have the same problem. Here some info:
- Device: Samsung Galaxy S5 (SM-G900F), Stock, not rooted
- Android version: 5.0
- Kernel version: 3.4.0-5640614 (2015-09-01)
- 'Smart network switch' is turned off
- 'Always allow scanning' is disabled
The problem started 2-3 days ago. When I turn on WiFi/WLAN the phone constantly turns it back off and on again. Didn't happen before, didn't change anything on the router (I have no access to it ) and didn't install a new app (as far as I can remember). I don't know if it only happens on this access point.
I made a log file (adb logcat) but am not sure if it contains sensitive information, is it save to share online?

The logcat doesn't contain any sensitive passwords.

I'm have the exact same problem.
Samsung Galaxy S5 (SM-G900T)
CyanogenMod (13.0-20151203)
Android 6.0 (Marshmallow)
Baseband (G900TUVU1ANE6)
Smart network switch: disabled
Always allow scanning: disabled
What's happening is as soon as my Wi-Fi finishes authenticating and connects, it is immediately disconnected and tries again. No other devices in my house are having any issues, so that eliminates the router. When I factory reset my phone the Wi-Fi begins to work again, so that eliminates my phones hardware. The confusing part is that I installed a bunch of apps such as AdGuard that could possibly cause an issue but everything worked and this started out of nowhere. Also, I factory reset my phone AGAIN and AGAIN, everything worked and out of nowhere while I was looking at my screen while idling, I watched as the Wi-Fi connection dropped and began the disconnect/reconnect loop...
I'm assuming it has to be a software issue because it only started when I updated to a newer Cyanogen. I'm about to test if other Wi-Fi networks have this problem and I'm also going to look through and post a log.
If anyone has any questions or suggestions that may lead to a fix, PLEASE help!
Thanks

Well I factory reset again, this time wiping the internal storage and everything is now fine. I did look at my logcat and there were Wi-Fi errors but I forgot to post them...
