[Q] WiFi strange behavior - Galaxy Tab 7.7 Q&A, Help & Troubleshooting

I got my daughter her tab 7.7 about 6 months ago & had been going on perfectly. Android version is 3.2 & I have no easy measures to update for the time being.
For internet connection she uses only my WiFi secure connection. It was working fine all this time.
Today she can't log to her Facebook account via the Facebook app. I checked it out to find that I can log in via the browser but not the app. I thought it may need updating and tried Google play store but I was astonished to find it not working too as it gives me "No Connection. Try again".
I noticed that the WiFi mark is white & not showing the green strength marks, but connection is confirmed by the WiFi name. I was shocked when I tried the software update from "about" when it gave me the "no connection message" despite working WiFi connection. Samsung app is working perfectly & I can update its applications.
Also funny thing happened, when I tried the browser it kept giving me certificate errors many times.
I tried the VPN as I googled around but nothing changed. Same problem.
Switching off & on didn't help either.
Any Clues??
Thanks

Most strange thing happened.
Everything is back to normal without me doing anything.
I left the tab for a while while writing the previous post.
When I came back I found the app update mark showing up, I turned on the WiFi & touched the update icon, the strength signal showed in the WiFi & update started the goggle app. All went normally. Facebook app worked & even the browser certificate errors disappeared. The software update in the "about" worked fine & checked & found no updates.
What is going on...
Can anyone explain to me what's happening?
Thanks

Try Power Cycling your modem/router. That often corrects connection issues. Presume other devices were connecting just fine?

[Q] 2 HTC Sensation problems...Please Help!!

Just bought my phone yesterday.
First problem is that I keep getting a notification in the top left saying 'unable to detect your time/date settings'. I have to press it and go to Perth +8.
Why was it never doing that with my previous htc??
Second problem just appeared today, I have connected to my home wifi, it SAYS connected and shows FULL connectivity, BUT on the top it has NO bars highlighted and the wifi doesn't work???
It worked fine during the day today and yesterday but now it's playing up?!?
Please help!
I solved the first problem of the time notification by unchecking ' Automatic Use network provided values'.
Second problem still annoying me though!
Maybe a different channel works for you. Search in the market for Wifi Analyser and check which channel gives the best result.
Thanks for the response,
I have already checked and it is on the best channel. It's not an issue with channels, the router is 5 mtrs from my mobile. Yesterday and this morning it was absolutely fine. And it even shows FULL bars on the wireless setting, but just at the top it shows none and doesn't load anything!
Have you tried turning off and on the wifi? That helped me once. Or rebooting the router?
yes tried both, still no good?!?!
Does the router regonize the phone? Have you tried connecting without security?

wifi connects but doesn't work

I have a stock Skyrocket (4.0.3-IML74K.CLE5) I am using as a media player. I keep it in airplane mode all the time with the Wifi on connected to my router. Yesterday the Play store started telling me there was no connection even though I was connected to my router. I went to the web and found I could connect to pages, but constantly get security warnings. If I click continue I can go on to see the page. Netflix tells me there is a problem connecting to Netflix. Voice search works fine. Google Voice tells me there was a network error. Facebook says it can't find a secure connection. Gmail says no connection. Zedge works fine.
I have tried four different wifi Hotspots both secured and insecure. I have tried telling it to forget the connections and reconnecting. I have restarted many times, removed the battery, and tried all the frequency bands.
The wifi icon in the notification bar shows a strong connection. And the little arrows light up orange and green to show activity.
I am guessing there is something wonky going on with establishing a secure internet connection, bit I have no idea how to fix it. Any advice is appreciated.
Q&A please

Sorry about posting in the wrong spot.
I have been using it like this for three weeks. The problem started two days ago.
Update: it works again. I don't know what I did to fix it, though. I went through every setting, and did turn off screen lock and unknown sources, bit I doubt that did it.
i figured it out, i had the same problem, the date and time were askew. updated them and it worked just fine ^__^

[Q] Google services don't work on wifi?

Hello,
I've been having problems connecting with google services for a week now.
When I'm connected to my wifi, the wifi icon appears with an exclamation point and says "connected, no internet". I thought at first maybe it's a problem with my wifi router so I restarted the wifi, forgot the wifi connection, and tried to connect again. That didn't fix the problem. So I tried to connect through mobile data and everything seems to work fine. I connected to my wifi again hoping that the problem is fixed, but it still says "connected, no internet".
However, I opened my phone browser and it appears I have access to any website. All other apps that requires internet also works on wifi. Only the google apps like the play store, gmail, youtube and others don't work. My laptop also does not have problems connecting to the wifi so I don't think it's a wifi connection problem.
This problem occured after I installed RootCloak xposed module on my rooted note 3 device running temasek's unofficial cm13 rom. I already tried factory reset and even installing other roms due to desperation and nothing worked.
I hope someone will be able to help me solve this issue.

[Q] wifi switches on and off

Hi,
since yesterday I have problem with wifi in my S7 (SM-G930F). It keeps turning on and off every second or two. I cannot switch it off because it keeps switching. I have rebooted my device, but it didn't help me. My phone is not rooted, it has stock 6.0.1 firmware. How to fix it? Despite it's impossible to use wifi now, it keeps draining my battery.

Boot to recovery and clear caches, reboot and see how it is then
done. Sadly, it didn't help me.

I'd backup with smart switch, and factory reset the phone
Or flash the latest stock ROM over the top with ODIN

I think it may be related with some strange wifi:
11-11 11:20:11.682 3462 3896 I WifiConfigStore: " Social WiFi" is a captive portal!

I saw it yesterday at work, but not authenticated. Now it is remembered in list. Sadly S7 has no option to forget networks out of range. Todays we have national holidays, but on Monday I will be at work and try to forget this network. I do not want to change rom because rom from my operator has wifi calling enabled and it is awesome.
Is there any chance that WiFi scanning is turned on? I recently saw that WiFi scanning will briefly turn my WiFi on then off repeatedly (shows with an indicator on top and I hadn't noticed that before). This first showed up when I installed Android Auto since it turned on my WiFi scanning option by default. As soon as I turned WiFi scanning off, the WiFi worked as it had before. It may be worth a look.
I've run into the same issue. Started yesterday, which may have come with the latest PJG update... Not sure.
But it's rendered my phone pretty much useless. The constant toast message popping up, saying "Network connectivity is available" gets in the way of the keyboard and I can't type a damn thing!
Like you, I've found it's stuck with reboots and a factory reset, which makes me think it could be the firmware or modem.
Edit: Disabling WiFi Scanning stopped the errors. Root cause is still unknown, though. I've never had to disable that before...

Yep. It was turned on, but I have it enabled since I bought this phone. Turning off neutralized my problem, but why it was broken for last few days when I haven't done anything with my phone? I rely on this feature because of localization accuracy and disabling it is just temporary fix.
edit:
Guys, one more thing:
do you have "Samsung Gear" app installed? I think this app is forcing to enable and disable wifi. Under localization it shows battery usage as high and it was updated last week

My phone does not have the Samsung Gear app installed. I do use Samsung Pay regularly and that was also updated (engine and app). I don't know how that would relate to WiFi though.

Turning off WiFi scanning stops the constant switching of WiFi. I tried removing the system settings permission from all the apps that had it (even the Google app) but it doesn't seem to have any effect.
I am seeing the same issue, I did not touch my screen in the following video
Video on Dropbox
disabling "Wi-Fi scanning" in location helps.
Hi,
I had the same issue before.
What I did was(Not sure how its displayed in english):
-Settings;
-Backup and Reset
-Reset network settings
I was having constant disconnections from wifi and it solved it.
Give it a try

Did the above solve the problem?
I am using G930F in US on ATT and encountered the same problem in past few days, where wifi kept turning on and off. Was searching this post, and found out that if i turn off wifi scanning i can get wifi to stay off (when i switched off ) and wifi on (when switched to on) and not flip back and forth.
go to settings.
- click on search
- type in improve accuracy
- select from choice
- turn off wifi scanning
Try that and hope that helps.
I have the same problem. The side effect is that it will drain the battery really fast.
As others have mentioned, after I have turned off the WiFi scanning in the location setting the problem is temporarily gone. However it should not be the solution as I really need the WiFi location to work. I don't know what is causing the bug.
P. S. I only see this problem starting from the last week or so. I leave the WiFi scanning location function on since I have bought the phone in May. Mine is Exynos version.
several Samsung devices have this issue.
I and several others have it on a note 4, and some people have also reported having this problem on S6 variants.
The problem is Google Play Services 10.0.84 version. Another cell phones with this version of Google Play Services have the same problem (ej. Google Pixel phone) but not all.
The problem is the Android Wear App. Deinstall the app and wifi works perfekt.
This issue starts with the last update of the wear app.
Hope i could help you.

I tried uninstalling Android Wear but it didn't make a difference. The wifi kept switching on and off.
As mentioned above, it's Google Play Services 10.0.84. Just disable wifi scanning until there is an update. Hopefully google won't take too long to push a fix.

Issues with Verizon V50

Folks,
I have been having some very annoying issues with my LG V50 and was wondering if anyone else has.
I have been having issues getting Hot Spot to work. It has only worked for a very brief time since I got the phone. It is working now though. I get an error about Tethering Functionality not working right now and to try again later.
I called Verizon and 1st level was unable to diagnose it and they opened a ticket. This was 4 days ago and Verizon has not contacted me.
I also had another issue which I've now discovered is related to my Hot Spot issue. So, I use an app called TuneIn Radio Pro. That app keeps thinking that I don't have network connectivity. (On cellular....on wifi it works). I've since discovered that when my Hot Spot works, that app works. When hot spot doesn't work that app also doesn't. I run speedtests and it connects. I seemingly have internet connectivity but interestingly I also cannot access tunein's web page from Chrome. But I can get to other sites. Seemed like a DNS issue but since it is working now, (and I have time) I can't test it.
Again, right now, Hot Spot is working. It has only worked for the last 4 hours and part of one other day since I got the phone 6 days ago.
Another issue (which I am hoping is a setting)....Voice input does not work when connected to bluetooth. So "OK Google" or voice input (Google) via the keyboard does not work.
Any thoughts?
I just tried setting up a hotspot and it seems there are quite a few more options than I had on my V30. I did get it to work once I chose to "unhide my phone" under the setup options. There's also a timeout due to inactivity, share wifi instead of mobile data, and the ability to block connections. I guess it's possible one of these could be giving you an problem. I would think if you have the share wifi selected but you're not connected to wifi that might create a problem...just guessing
I don't use Tune-in so can't really help with that specifically but I've had no issues streaming with other apps.
As for voice commands, I can't bring myself to talk to my devices and I have as much of it turned off as possible.

So this issue has still been going on. My hotspot will work for a day or two and then it goes back to this error condition. But now I have been going on 4+ straight days where it hasn't been working. So, I have stumbled across a situation where I can get hotspot to work.
I have OpenVPN app on my phone. If I open a VPN session (I have 2 connections to my home routers), I can then get the hotspot to start. Interestingly, hotspot traffic is not going over the VPN. I can even turn off the VPN and the hotspot stays on. But I cannot restart it unless I turn on the VPN.
This issue isn't being caused by any software on my phone. As when I first got the phone and this issue came up, I performed a factory reset and when the phone started up for the 1st time, I immediately tried the hotspot and I got the error.
I also called Verizon today to find out what was going on with my ticket from 2 weeks ago. It was escalated and then closed by the network team with no explanation. Sigh....So they re-opened it. The tech on the phone also called LG while working with me and LG told her that they've seen this issue, but no additional info.
Has anyone with a Verizon V50 been able to consistently use the Hotspot without issues? I am having so many problems with this phone that I am ready to throw it out the window. In addition to the issues I stated earlier, I also found this morning that I was not able to get to eBay (In addition to TuneIn.com). I had to switch to wi-fi and then eBay loaded just fine. Since then, eBay seems to work. IMO, this is a network problem
Over the last 2 weeks, my Hotspot worked from Friday to mid day Sunday. (maybe coincidence) And therefore tunein.com worked. Other than that, I get the error.
Verizon had been completely worthless. They closed my first trouble ticket. My second ticket has been open for 3 weeks without progress. I called today and they put me on with Level 2. I had to run to a meeting after a while, the Level 2 person said no problem tell me when to call you back. I told him 2 hours and he said no problem.....and no call.
I am just curious if others are using Hotspot successfully.
Thanks,
Update to my previous post....I haven't been able to launch the hotspot functionality since yesterday morning. I get the message of "An error occured when activating this functionality. Please try again later."
I may try a factory reset to see if that changes anything...
Decided to factory reset. That didn't change anything. Without installing anything after it was done I tried to create a hotspot and got the same error message.

THANKS!!! Exactly the message I've been getting.
Verizon has not been helpful until now. They've pretty much ignored me and closed my tickets.
Hopefully I get further along. I got a better tech support person this time. He escalated it to the network engineering team. This is a network problem as if I start a VPN session (using OpenVPN Connect), I am able to launch the hotspot.
The hotspot is a symptom, not the cause. I am just curious if you have the same exact problem as me, when you are not able to launch the hotspot, bring up a browser and try to go to tunein.com (through Verizon's network, not over wi-fi). Mine won't work. When the hotspot is working, I am able to get to tunein.com
Yep, exactly the same issue. The tunein link and the Connect Garmin app give me the same error. After I sign in to Garmin on wifi it will work as normal but definitely indicates some type of network issue.

I just got an update pushed. System Update 2 V450VM10f.
After the update, the Hotspot seems to work. I am also able to navigate to those URLs where I couldn't get to previously.

While I am now able to launch the Hotspot, that feature is not very reliable. It stays up and "running" but my laptop will stop working after some period. Usually I get about 5-20 minutes of usage. If I disconnect my laptop and re-connect, it starts to work. (But a pain as I VPN in to work and I have to start that all over)
This phone has been a an exercise in frustration.
