[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!

[Q] Wifi problem on 2.1

Hi,
on my x10 with 2.1 nordic I have strange problem with wifi.
When i turn it on it find and connect to my wifi network but after a while (when i'm not using the phone) it just brake the connection and cant connect again until i do it manually.
Any ideas? Its really annoying me that my phone is using 3G instead of wifi after some timeout.

Mine does this as well. When I have WiFi enabled it doesn't use it unless I disable it and re-enable it.

Same here
Also it does another strange thing.
When I have connected to my Home Wifi and entered my password everything is fine. When I turn my WIFI off and back on. The saved connection to my home network is shown + again my home network without the PW. Very strange.
I am on the global generic 2.1.

I got round this by setting the wifi sleep policy to "never".. uses a bit more juice but I'm still getting a full day out of it.

Play a little bit with battery saver app. It will help

wifi scan not working

Hi,
This does not seem to be the same as the other wifi issues posted here - I did check before posting.
I have a problem that my Nexus 7 is not scanning for networks unless I press WPS button in the wifi settings. If I choose scan, switch wifi off and back on, or if it drops out for some other reason, it does not refresh the list of access points (i.e. it only shows saved networks, but does not attempt to connect to them). As soon as I press the WPS button, it starts scanning, once the access point I want appears, I can press cancel, and I can connect. This started after a couple of owning the device.
The problem isn't that it's dropping the connection (thankfully this doesn't happen too often, but it's annoying when it does, as it doesn't re-connect - I have to go back and press WPS again), it just fails to scan for networks until I hit WPS. My router at home doesn't support WPS, so this seems absurd. It's not just at home either, any access point, be it in a cafe, bar or office, it won't find any networks until I attempt to connect via WPS, then it shows all access points in range. The scan option from the settings appears to do nothing.
This started happening on 4.1, I was hoping the upgrade to 4.2 would fix it, but I'm still getting exactly the same symptoms after the upgrade.
Thanks,
Scott.

I am experiencing the same exact issue. I only see access points if I first press the WPS button and then cancel. Did you ever find a solution?

Yes, I did. I noticed that, even after a factory reset and rooting, my old wifi networks were still there. I deleted all the saved networks and the issue stopped occurring. It's re-appeared once since there after attempting to join a network at once my client's offices, deleting this particular network resolved the issue again.
Hope this works for you as well.

WIFI - Issues all over again

Does any one remember the cure for the WIFI issues on previous galaxy handsets it might be a similar issue im seeing on the S5.
When i return home the WIFI doesn't automatically connect it states "Network disconnected. Sign in again" in the pull down then when i click the notification it takes me to the WIFI setting and it states "Sign-in is required" if i click on the network and click connect its all happy again and connects!
Has any one else seen or solved this issue im seeing it on both mine and the Wife's S5 but everything else connects happily without a problem.

It doesn't ask you to save a password if i forget the network and re-enter my password it will connect the the next time i leave the house and return it will ask me to sign in again and not reconnect automatically

Same issue - Alernate FIX -
Had the same issue, tried the resolution of
Step 1 Go to the home screen on your phone.
Step 2 Select the telephone dial pad.
Step 3 Dial *#0011#
Step 4 Press the settings button on phone and select wifi.
Step 5 You should see the safe wifi button on so just press it so it turns off.
Reset connection (forget connection then established connection again) seem to work, but then battery life was horrible. Unfortunately didn't think it was a good trade and turned safe-mode back on. Working fine for awhile, then Network Disconnected alert, days later. So as a fix,
1. >Wifi >Advanced >Disable (uncheck) Smart network switch.
2. Forget connection, then establish connection again. Works no issues.
One of the benefits of the Samsung Galaxy S5 is the battery life, why would I want to sacrifice that and have my battery dead in the late morning, hope this helps.

wifi works great for me

great for me
wifi works great for me Thank you

fix please
Nope the fix doesnt work
the same issue all over again
please help

your problem is in access point config
check your access point configuration security

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...
