Slow Wi-Fi detection - Galaxy S 5 Q&A, Help & Troubleshooting

Hello guys, sorry if it is a double post, couldn't find anything near to my problem on search. Here I go:
When I get close to a Wi-Fi connection which is already configured on my phone it takes a time to realize it is near a known wifi network, like a few minutes, while a cheap phone goes connected almost instantly.
Wi-Fi is on while suspended.
The phone is a SM-G900M
4.4.2 Stock with a few modification
root/xposed framework + few modules
Thanks in advance

Anyone?

[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!

WIFI Issues

I've had my Nexus for about a week now and noticed two strange issues with the WIFI connection.
1. I can connect to WIFI successfully at home but as soon as I go out and it switches to the 2G network and then later go back inside the WIFI doesn't auto connect it will stay on 2G, I have to disable and enable WIFI to connect to my home WIFI, is there a way round this or is it a bug?
2. Whenever I'm out an about and the phone detects a WIFI network even if its not configured to connect to the WIFI network the phone seems to disable 2G Data connection and continually notifies me of a WIFI network being in range and wanting to configure it, is there anyway of disabling this behavior and allowing the 2G Data connection to be active when no configured WIFI network are in range?
Any help would be much appreciated.
Thanks
Jon
Really can't help you much on the settings as I don't quite have my N4 but you should always turn wifi off when you're not using it. You will get much better battery and you wont have problem with #2. Sorry I couldn't really help much.

I have the same issue number 1. I find the battery is getting used quickly and the wifi will not connect. if i disable then enable, it quickly connects to the known wifi signal. I can see a different battery decay slope if I let this problem persist for a few hours, it then reverts to its usual slope once wifi is restarted. This problem usually only occurs once a day on average. I hope someone knows how to solve this issue.

[Q] Wifi keeps reconnecting

My S4 keeps reconnecting to my wifi for some reason. I get the toast notification saying "Connected to <SSID>" that will sometimes pop up every 5-30 seconds, but it never goes more than 30 minutes without doing it. My router is an Asus RT-AC66U. I've tried forcing 2.4Ghz only, 5Ghz only, changing the preamble (short, long, auto), changing the channel (manually specifying each channel, and also tried auto), and even manually assigning an IP address on the phone. None of these things help.
I have "check for internet service" under the advanced wifi options disabled, and also have it set to keep wifi on during sleep.
The phone shows Very Good signal quality. Using wifi analyzer shows a signal strength of between -45 to -68 db, depending on what room I'm in, so that's definitely not the issue. It even does it sitting in the same room as the router. No other devices have an issue, including my roommate's S3.
I can fix it by turning off wifi power save mode (*#0011#), but then my phone heats up quite a bit whenever I'm using it, and my battery drains at 10%/hour even when I'm not connected to wifi. So that's not really a solution.
Is there any other fix for this? It's a bit ridiculous. I'll load a webpage and it'll interrupt halfway through when it re-connects to wifi. Since it keeps reconnecting to wifi, it causes all the phone's connections to be re-initiated, and also seems to trigger Google Services to update the phone's location. This results in Google Services (NetworkLocationLocator) holding a wakelock for 1/3 of the time.
So it seems the problem was IPv6, specifically IPv6 that autoconfigures. All the wifi networks I typically use are dual stack IPv4/IPv6. What I'm guessing happens is that the phone doesn't wake up for some of the IPv6 broadcasts, and then the phone reconnects to fix this once it realizes it's out of sync. Turning off power save mode means it gets all these packets and doesn't have to reconnect.
So I fixed it by having Tasker disable IPv6 on wifi whenever it connects to a wifi network (it's re-enabled if you disable wifi or reboot). Run this as root:
echo 1 > /proc/sys/net/ipv6/conf/wlan0/disable_ipv6
I wonder if this is just a bug in the chipset, or if it's a driver issue that can be fixed in a later update.
I had the exact same issue with mine (same router) and solved it by disabling WMM APSD in the router settings. Wireless>professional tab>5GHz drop down box>Enable WMM APSD>Disable.
A guy in the other GS4 Q&A forum gave me this solution and I haven't had an issue with it since.
I have this same issue... so when my Wi-Fi is dropping like that, I disable the Wi-Fi power save mode by dialing *#0011# then pushing the menu button and selecting the Wi-Fi option from the pop-up, the psm button is there. Fixes it every time, doesn't stick thru a reboot tho.

Hello, I'm having the same problem but I'm new to Tasker and don't know where to put that command. Would you mind showing me how to implement it please? Thanks.

I'm running SACS Custom 7.1 with Faux kernal, and since I update to 7.1 from v7, my phone doesn't save any wifi profiles I connect to. Another thing I've noticed is no image shows up when recieving a call, so I have no idea who is calling. I got a 3rd party caller id from the market to fix that, but still a strange issue.
I am experianced with phones, but haven't posed enough here to post in SACs page, so any ideas would be helpful.
I tried looking at settings from 3minit or XPOSED, but nothing has changed since V7, so I'm wondering where to look.
The wifi profile shows up in data/misc/wifi/wpa_supplicant.conf, but only the one I am connected to at the time. If i disconnect and reconnect I need to re-enter the password.
Not important but annoying.
Thanks for your help in advance, you guys are awesome!

Wifi issue is faux kernel flash a different kernel. A module from xpose is the culprit sorry I forgot which one was it. To solve all your problems just do a clean install of v7.1 and when doing that make sure you click stock kernel or flash a preferred kernel. I dont use xpose so I dont have that problem so its your choice if you want to use it just read like 10 pages from the thread to find your answer.

I have to do this same thing and it works for me perfectly. A little bit of a hassle after reboots, but it works. I sent this to Samsung and they've opened a ticket on it (reportedly) to be addressed as they've had a lot of complaints about WiFi areas with multiple Access Points.

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.

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.

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...

Wifi keeps switching on an off

Dear all,
I'm experiencing a somewhat weird issue with my Xiaomi Mi A1 (Oreo) which started a couple of months ago.
My WiFi keeps switching on an off.
* When I turn off WiFi, 4G comes up. After a few seconds (I can leave the phone unlocked at the desk, it almost happens instantaneously) Wifi turns on by itself and connects (just as if I switched it on manually).
* When I activate the mobile Hotspot, it switches off after a few seconds, disconnecting all devices connected, only to switch on the regular Wifi after a few seconds and trying to connect to the next network.
* In random cases, Wifi just switches off despite being connected to a working network and while I'm using it.
This is somewhat annoying, and I didn't find any solutions online. Any ideas? Any more information you need (sorry, I'm new here)?
EDIT: This is not the "Turn on Wifi automatically" setting, and it is also not related to location services.
Flash stock rom, sounds like a software bug. Otherwise, return it while you still can.
Thanks.
