WLAN Hotspot doesn't work on Android, looking for competent help - General Questions and Answers

Hi,
I'm using a Sony Xperia Z5 Dual Android 7.0 facing that issue making me unable to use my WLAN hotspot (which it pretty anoying cause it doesn't only dissallow me to share my internet connection but also I can't do other network stuff between devices I'd use that hotspot for).
So when I try to turn on my the hotspot it simply turns itself off again after small amount of seconds. When I got to WLAN hotspot in settings then I have the active button to switch the hotspot on while it shows me tbat it's of at the moment. Doing that it says "Activating hotspot..." (pretty exactly that) until it's going off again with a quick "Deactivating hotspot" and you could activate it again but it will do nothing again than say "activating" and go off again. While it is "activating" it already shows the active hotspot icon in the top bar of the phone and the hotspot settings are as well already active and no more inactive greyed out. But only for nk idea, 3 seconds probably. Within that short period of time my laptop didn't find my phones hotspot but that might just be down to an to high delay in scanning and finding so I don't know wether it would shortly pop up seeable for other devices.
Earlier that day I had my hotspot working actively (nobody actually joined) but it worked and would have if somebody joined because that issues is not new to me on my phone and when the hotspot activates, then it also works. But half of the time it seems when I want to use it, it doesn't work. I haven't changed any settings inbetween or restarted my phone. It was probably on for one week, but after then trying a restart it still didn't help.
I already changing some one-click stuff like just turning out WLAN, turning off or on data save mode (which stops background data for all apps in mobile internet and WLANs marked as hotspots), turning off or on mobile data. But well, I don't know anything else and earlier it worked with all the same settings so what could be the problem behind that?? Besides that my phone always just works completely normally without any issues, WLAN always works without problems, only Bluetooth sometimes doesn't want to activate and then I see it active after some minutes or hours later, but that can always be fixed with a restart if I needed it instantly. If you just wait and it is active then tough, it is kinda awoken and works instantly then again shutting it off and on.
Phone is not rooted btw.
Ok long text, but please if you have any ideas tell me..
Greetings, HelpsToMes

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?
I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.
Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.
I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?
Fully charged. It even happens when pluged in with the charger.
My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.
Would you guys having this problem also post it here?

Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.
Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.
Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again
I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.
same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone
How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.
Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

Nexus 5 WiFi Crashing Phone

Hi all. I have a weird issue that after Googling it doesn't seem anyone else has had.
The issue started earlier today, in the morning. I was using my phone on the WiFi and it was working phone, then my phone crashed, restarted itself.
I noticed it wasn't connected to the WiFi, went to the WiFi settings and where it usually says the list of networks it said "Turning on WiFi" and the slider at the top was greyed out so I couldn't turn it off.
I tried airplane mode and that didn't help. But the phone was working fine on my mobile data so restarted.
Now the weirder part starts. I basically have an issue where, if I turn on the WiFi, my phone crashes, or doesn't act like it's turning the WiFi on.
Even going Settings and then pressing on the WiFi option freezes the phone.
The problem started when I was still using 4.4.4 however since the problem developed I've used my mobile data to download the updates and now have 5.1.1 I think.
The problem persists even after updating to the most recent version and doing a factory restore. The phone is currently completely stock with nothing downloaded on to it. All I did is go through the first time setup for the device.
The WiFi currently is off, and the phone is working however it won't connect to my data, it has the signal bars and then an ! instead of a 4G icon.
If I try to turn the WiFi on it crashes the phone.
The phone is still under warranty so I plan on contacting LG on Monday however it's currently 3:34 AM on a Sunday so I have a day until I can call them and was hoping for a solution in that time.
Thanks in advance. I have the phone to hand so anything you want me to test I'm able to.
There is some information I didn't type as I don't know what is important was trying to avoid a wall of text so if you have any more questions I'll answer I best I can.
Thanks for reading, I hope you can help!

Help with wifi bug and hotspot woes

I have a sprint galaxy S6 that I rooted years ago with the pingpong root. So its on the stock rom and never updated passed 5.0.2 I believe. I haven't done much with the root except enjoy the use of the hotspot that sprint tries so hard to deny users. However lately I've been having problems. The build in hotspot no longer works, and I suspect its some stealth update from sprint. It'll turn in without issues, but then I'll watch my mobile data disappear. The 4G blinks off, then it tries 3g, then nothing, then 4g, 3g, nothing, etc... Turn the hotspot off and everything returns to normal.
Fine. I'll download "Wifi Tether Router" and use that. However, every 5-15 mins my laptop loses connection and the hotspot won't show up in the list of networks despite it still running. What I suspect happening is my wifi is quickly turning on and off, disrupting the hotspot. Now, after getting the phone and going through all the settings, I turned off connection optimizer and unchecked the allow scanning. However every once in awhile while using the phone, if I happened to have the drop down menu down.. I'd notice the wifi quickly cycle on then off. It never affected anything I did so I left it be. Now when using the tether app, I rechecked all my settings, even turning off "keep wifi on while asleep" and checked the dev settings to make sure the wifi scanning/roaming was off. I am completely lost. Are there any settings I'm missing? Is there anything I can do with root to stop wifi from turning itself on without user interaction?
Or, is there any way to fix my built in hotspot? I have a new laptop and now have more use for this function.
Thanks guys.

Galaxy S7 T-Mobile (Android 7.0) WiFi disconnects as soon as screen is off

Hey there, I have this S7 that would just disconnect from WiFi as soon as the screen goes off. When I try to make VoIP calls as soon as I put the phone to my ear and the screen goes out, the WiFi drops. I also confirmed this by running a continuous ping, soon as screen is off, WiFi drops.
Now this only happens at work. At home all is fine and dandy. At work we have open WiFi APs with guest logon pages. Being on the IT team I did create an SSID that was WPA2 locked to test this, but the problem still persists. I tried 5 GHz and 2.4 GHz, Ijumped through every possible solution I could find in the internet, but nothing seems to work! My old Xiaomi worked just fine, what is it with the Samsungs? anyone got an idea?
I don't think that will solve your problem but as nobody replied you, maybe you could try to see in your Galaxy S7, in parameters, then Connections, then Wifi, then at the top right corner, clic on "advanced", and there you have some parameters for the wifi like the one to put Wifi Off when phone is asleep.
Also, check if you have installed any battery saver app that would interact with your Wifi and turn it off while phone is asleep, or something like a Greenify app that would put asleep the wifi service (if there is one).
In the end, if your problem is only at work and not at home, then I would say the problem comes from your router at work. Something in the settings maybe disconnects devices when they're under certain percentage of use or something like that.
I hope that will help you, or at least help you find other things to look for to identify your problem ; )

Android 10 - wifi sleeping while screen locked

Hi guys!
I did a lot of googling and searching through XDA, but never found a solution for my problem, so I might as well try it here.
Recently I updated my Sony Xperia X Compact to AOSP 10. Now when I am connected to wifi (and it does NOT matter whether it is 2.4/5GHz or IPv4/IPv6, I tried everything) and my screen is locked, my system seems to put the wifi connection into some kind of battery saving mode. Notifications then will hardly come through. You can also see this in WhatsApp Web - every two minutes or so, "Phone not connected" will show up, and messages take up to 2 or 3 mins to get delivered. Then I can use Whatsapp Web normally for 30 secs, after which my phone seems to disconnect again. If I unlock my screen, WhatsApp Web will immediately (!) start working normally again, also missing notifications (e.g. Signal) will then come through.
While of course this might be a ROM bug, I am at least 100% sure it IS ROM-related, as I used exactly the same phone with exactly the same router without any problems while on Android 9 LineageOS.
Another interesting thing - if I charge my phone, during charging WhatsApp Web works completely without problems. The moment i UNPLUG the phone, wifi gets somewhat throttled agian.
Does anybody know a working solution for this? I do not have the option "Disable wifi sleep" or something similar - i believe Google has dropped this option somewhere around Pie.
Thanks in advance!

AFAIK there are kind of wifi energy saving options on some devices. But IDK if you can enable or disable wifi when phone is locked
