Hi,
I have a laptop, TV and iPod touch connected to my router via Wi-Fi, and a desktop via LAN. It's always been completely stable, rock solid. 2 weeks ago I bought a Sony Xperia T to replace the iPod, and since then the router has been freezing up every 15-30 mins, cutting off every device connected to it and not responding to any attempts to log in to it. The lights on the router don't indicate any problem and if I leave it alone it will unfreeze itself within a couple of minutes.
If I turn off the Xperia's Wi-Fi, the network goes back to being completely stable again all day. Turn the Xperia's Wi-Fi on and the router will freeze within 5 minutes and then again every 15-30 mins.
Google search tells me this is actually a fairly common problem with android devices but nobody seems to have any solution. I've upgraded my router's firmware, tried assigning my phone a static IP address, told the router to use g mode only, tried a range of different Wi-Fi channels, none of this had helped.
The problem happened on ICS as well as the recent Jelly Bean update.
Does anyone have any idea what my phone might be doing to screw up my router so much?
Thanks.
Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.
You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.
This problem happened spontaneously with all the android devices in our house. Router had been set up for a month with great performance and then the day before yesterday things just got crappy on our wifi.
Here's the problem:
There's a significant lag between trying to get data (refresh Facebook app, load a Youtube video, go to a web page in Chrome, whatever) and actually getting the data. This occurs on two Nexus 5 phones running Lollipop and a tablet running Kit Kat. Sometimes it'll be 10 to almost 30 seconds between trying to view, for instance a youtube link, and the video description and video actually starts to load. Sometimes I'll get a network timeout. A laptop running Arch Linux on the same network has no such lag.
Here's the weird thing. When I do a speedtest with the Ookla app, it will take a VERY long time to "find the best server" (it's been a minute so far while I've been writing this post just sitting at that screen) but once it does I'll get really excellent speeds. Basically maxing out the possibility of my home internet connection (40Mbps+). Same with upload (13Mbps). Ping to server was 10ms. When I use a terminal emulator to ping a site like google or facebook it will ping with typical wifi reaction rates, usually under 25ms consistently.
Wifi reception on the 2.4Ghz band is great. throughout the house. Different wifi channels do nothing. Note, my wi-fi signal is not dropping, so it's not that issue that's often reported. Reception is great, there's just major lag between trying to get data, and actually connecting.
And again this isn't just one device, this is three separate devices running two different flavors of android. So I'm guessing my router one day decided it didn't like android. Because like I said, things were great until literally just Thursday, with no change in settings on any devices or the router from us.
Yes, I've done a power cycle on the router, which is a Netgear C3700
Any ideas on what might be happening?
It's possible there is an IP addresses conflict. Do any devices on the network have a static IP?
No IP conflicts that I can see ever have been the issue.
If I reboot the router the problem goes away for a couple hours, but then I get the WiFi lag soon enough. I've seen a lot of reports about lag on WiFi (with bad ping results) on some other google searches I've run, but they all point to problems with IPV6, which my router doesn't support at all, so there's nothing for me to turn off there. I can't find any IPV6 settings for anything anywhere on the phone itself.
I don't see any other problems with my router and android devices specifically mentioned anywhere.
Are your android devices using different DNS servers than that of your laptop?
I have never specifically set up any DNS settings on any device in the house. Not even sure how to see what the settings for that are on the Android devices.
I'll try using a static DNS settings from the router instead of the "let my ISP choose" as I have been having problems possibly related to DNS issues on a wired laptop machine (running Linux as well).

Try Google DNS or something
I'm fairly convinced it's not a DNS issue. If it was, rebooting the router would have absolutely no effect at all. But a reboot of the router (unplug and re-plug, a software initiated reboot doesn't seem to work) makes the net fly at great speeds and pings on all devices. For a while. Then it goes bad.
I'm testing a 3rd party app to change the DNS settings to 8.8.8.8 (google) on one android device to see if that one behaves differently. Setting the router to custom DNS settings caused me to get locked out of all internet completely. I couldn't even get into the router software from a wired computer to see the settings anymore. It was like the router didn't exist anymore.

Try setting static IP's for the Mac adresses of the phones in the router and on the phone. Make sure it's outside of DHCP lease boundry of your modem. Sounds like conflicting IPs as already mentioned.
The responders have good intentions but really don't understand the problem entirely. I've faced similar issues.
To quickly dumb down the problem:
Wifi stays connected, but all packets are lost for 10-60 seconds or until wifi is toggled off then on again.
We'll call this Wifi-Connected-No-Connection (WCNC) for the purposes of this thread for easier reading.
Here are my findings...
It may be related to this issue on the google code discussions, there are mentions of complete drop out while remaining connected: https://code.google.com/p/android/issues/detail?id=64706
This has affected both N4 and N5 devices since Jelly Bean. The issue persists in Kitkat but I haven't followed to see if it's entirely been resolved in Lollipop as I refuse to upgrade until certain other issues are worked out with L. If you're good at searching you'll find posts about this drop out issue from a decent time ago.
AP isolation doesn't help.
Modifying most other settings for the router did not help.
What DID help though, is turning the router from N/G mode to B/G mode. I had no WCNC issues with that. Of course, that meant slower speeds, significantly slower speeds. Back on N/G, I find this problem happens pretty frequently.
Packet loss happens at the connection level. Pinging the router means some or all packets are dropped. This is NOT a dns issue.

This makes a lot of sense. Wonder why this would happen with one router set to b/g/n and not another set to b/g/n (the a/n settings are only for the 5Ghz band)...
I have four handheld Android devices and, currently, 3 standalone WAPs plus Verizon's FIOS router.
.
None of the four devices can maintain a connection to any of the standalone WAPs or the router for more than a half-second or so: they solicit the PW, Authenticate, connect briefly, and then drop the connection.
.
I normally have only one WAP, but added the two just to make sure the problem was not in the WAP. Ditto Verizon's router, whose WiFi is normally turned off, but turned on now for troubleshooting.
.
For the life of me, I cannot think of any changes I have made in the week leading up to the onset of this problem.
.
One of the standalone WAPs is an Orbi Mesh system, but currently with no satellites - the satellites having started to act weird with onset of the problem and therefore having been turned off.
.
I also have two instances of AndroidTV running: one on a Sony Bravia TV and the other on an NVIDIA SHIELD box. And, weirdly, both of them are able to hold a WiFi connection - but UNABLE to hold a Ethernet cable connection. Same appearance as the handhelds over WiFi: connection gets dropped, only almost instantly so the screen just kind of vibrates with the connected.
.
If I turn off all standalone WAPs, leaving only the WAP in the Verizon router, the problem persists - with the Verizon router's WAP on channel three and, according to the WiFi Manager Android app, no competing signal sources on channel 3.
.
The problem persists even with the handhelds within 10 feet of the various WAPs.
This started about a week ago. Before that, no problems. And I don't *think* I have changed anything.
Right now, the only thing between me and hiring somebody to troubleshoot the problem is the weirdness of the problem - and the fear that their billing by the hour could cost me too much.
Can anybody point me in some direction?
Hey guys,
So basically I drive a 2016 Volvo V70 (car model not so important tbh) and before I got my Galaxy N20U I used to have an iPhone 8+.
At the time when I connected it to my car's bluetooth system, things used to run quite perfectly when playing music. Using the car's buttons I could rewind and fast-forward songs by pressing and holding in apps like Spotify.
Now with the Galaxy N20U, answering calls works sorta well, and I can skip songs forwards and backwards by short-pressing the car buttons, BUT I can't "slide" or "seek" the tracks, as in fast-forward or backwards, like I used to be able to do with the iPhone. I did all sorts of basic troubleshooting like unpairing and repairing the phone, resetting, trying other music players; but the problem still persists.
I messed around with the bluetooth connection type in Developer Mode settings on the Galaxy, but tbh I don't really understand what the settings mean or which one should be right. I'm not really aware what bluetooth version my car has either, but I think it would be an older version since it's 2014-2016 technology.
How can I fix it or tune the settings of the Galaxy in order to solve this? Or are there any apps I could install which fixes this issue?
Another problem with the Galaxy's BT connection is with my Windows 10 laptop. It's a pretty new laptop (HP Spectre 15 x360 2019) running the latest version of Windows 10.
Basically I did what everyone would do and I linked my Samsung to Windows, so I could have a similar continuity experience like Mac/iPhones have, like having a stable and automatic connection, picking up calls and texts from your laptop, and most importantly that your phone shares hotspot automatically through Bluetooth tethering when you're outside of home.
I tried several things like linking and unlinking through Microsoft's "Link Your Phone", and even tried with Samsung's Dex. I tried with both functions on, or one of them being unlinked.
The problem still persists, that it's not an automated and constant connection between the laptop and the phone, and that especially when it comes to automatic bluetooth tethering; then I always have to do it manually through clicking through several menus on Windows and creating an Access Point connecting to Bluetooth like some sort of a LAN connection. Every single time. And even when this connection is established, I'd see a LAN icon on the status bar (instead of signal bars) and when I expand the menu, it doesn't even list the current connection it is on (like "Samsung bla bla bla: Connected"). Instead I just get nearby WiFi networks and that it's searching. I DO get internet though and it works fine for the most part, but once I leave the room and the phone gets out of the range, or I put the laptop to standby, then I have to repeat the process all over again.
Even when I opt to sharing internet from my phone to the laptop through normal WiFi hotspot, I notice that the connection drops frequently.
To summarize, when it comes to both the car and my laptop, my Galaxy N20U does connect to them and offers the basic functionalities of the BT connection, BUT it misses other basic functionalities and it tends to be a half-baked, unstable connection.
Please help me out with this! Running the latest versions of softwares on all the named devices here.
For now turn off Developer options.
Clear the system cache on the boot menu
Reset network connections.
Pretty harmless and it may fix it...
dont have that problem
