Wifi suddenly not working and does not connect to any AP - ONE Q&A, Help & Troubleshooting

For some odd (and scary) reason, my wifi wont connect to ANY access point. Ive turned it on/off (both wifi and phone), connected to other APs, etc. but nothing.
I did not update so nothing has really changed.
What is wrong? It only says in the wifi settings "Saved" but when I hit "Connect" it doesn't do its usual "Connecting..." text.
A message shortly then appears saying "WiFi Connection Failure"
This is very urgent, please help.

Not only reply...incredible...

I have the exact same problem since a couple of days now. This is just terrible. I even updated to Sultans CM13, but the problem remains.

[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?

[Q] Wifi Keeps Disconnecting and Reconnecting

My wifi network keeps disconnecting from the internet and reconnects right after. "Connection to Wi-Fi network" keeps popping up. I can still browse the internet, but if it happens to be when the internet disconnects for one second, the page cannot load. I have a feeling this is a software or hardware error, I had this problem since I got the tablet. If you look at the settings where it mentions wifi connection it will go from "Connected (network name)" to "no internet connection" then back.
This happens at school, starbucks, home, etc. I am very mobile, so it isn't the wifis problem. I have strong signals! And this doesn't happen all the time, but it does happen a fair amount. It is very annoying.
Anyway to fix this? Is this a hardware problem or something wrong with settings? Thanks.
I tried " http://support-us.samsung.com/cyber/popup/iframe/pop_troubleshooting_fr.jsp?idx=410460&modelname=GT-N8013&modelcode=GT-N8013EAVXAR" and it didnt work.
i brought a new router and this problem started to happen to me, not sure how to resolve the problem, it doesn't leave you without internet for long periods so i am not going to worry over it so much.

WiFi acting all weird on me lately

I would say the last month or so the wifi on my N5 has been acting all weird, I don't know what have happened. Let's say I'm connected to the router (it always finds it), I try to go on a site but it just doesn't seem to be active even tho it says connected. Sometimes it helps to just disable and enable wifi, or airplane mode. I've tried changing channel on my router but the problem seems to come back, I don't know what to do?

[Q] Wifi suddenly stopped working

So I flashed a Boost Mobile Moto G a few months ago to use on Selectel. All was going well, until a day or so ago when all of a sudden my wi-fi stopped working.
At home, I (sometimes) see the connection listed under Settings, but if I click it I never connect. Sometimes even if I'm sitting right next to the wireless router (as I am right now), it is listed as "not in range". Meanwhile all other devices in the home work fine.
At work, we have a wireless network that is open but requires a browser sign in (like you see with free hotel wi-fi). It will show up either as "Not in Range" or "Saved", but if I try to connect to it, it just does nothing. Rarely I was able to get the "Sign into wi-fi" alert, but when I click that and go to the browser, I'm never able to connect.
I have tried the obvious steps of disabling and enabling the wi-fi / powering on and off, etc. I reset my home wireless router a few times as well though I don't think it's that since it is happening in other locations as well
Any thoughts?

Wifi connects & disconnects repeatedly whenever screen is off

Whenever I turn the screen off on my s7, it will automatically disconnect my wifi and after a few minutes, connect back for awhile before disconnecting again. Anyone encountering a similar or the same problem? I made sure the settings for keep wifi on during sleep was set. I tried resetting my network from the "back & restore" place but didnt help.
How I knew was notifications for whatsapp was always always delayed, I tested by sending a message from my spare phone to my s7, my s7 would then only receive the message anytime between 1- 3 minutes, and sometimes the phone will disconnect from wifi immediately after receiving the message.
I noticed this too 2 days ago. I did not updated the firmware pr something else. I thought it was my router. Today i flashed the superman rom 1.7 and i saw that it lost the wifi connection again. I will observe it for the next few days. I havent had this problem before. Weird...
