Recently purchased a 2013 Wifi only N7. Upgraded to Lollipop and continue to have intermittent WiFi issues, where WiFi will show connected in the notification area with an exclamation mark. This usually occurs after I docked the device and been away from it overnight or for several hours. The only way to get back on the network is by toggling WiFi off/on. There is another WiFi network in my home, but it is set to a different channel and we are far away from the neighbors. The AP is nearby with clear line of site, and other devices (e.g. HTC One, iPad) have no issues.
I have read that this is a general problem with Android 5.
I would check your Wi-Fi settings in settings, Wi-Fi, three dots, advanced.

There's not much to change in there. Since the nearest network is only 2.4ghz, I changed from automatic to 2.4ghz only. Not sure that's going to fix this.
What about your settings for WiFi being on or off during sleep? Is it set to always on?

Yes, it's set to the default, which is "always on." Should I change this?
I would like to invite everyone to try if they have the same problem
For me, I have done a lot of testing, and I have found that, with any open WiFi hotspot (ones doesn't require wifi password to connect, with captive login or not), even G4 saved the network, half times it won't autoconnect.
When you go into wifi setting, the network is there, and there is an message below the nextwork saying:
"internet is unavailable, cannot autoconnect"
But if you tab it manually, it will connect and fine. I tested it with multiple hotspots and all have the same problem. I tried all different ways like delete the networks and re-add, nothing works.
Any of you have same problem please confirm below and let us know if you have found a solution, this is yet another ridiculous problem LG4 has and not fixing it, who are they to decide internet is available or not on a wifi hotspot?
my G4 is 812 10c
Any one encounter the same problem?
Yes I have this issue also. Don't know what would be causing the problem

Thanks for confirming,
Very annoying issue and I am surprised it hasn't be raised and discussed in here.
For me it is way worse than occasional touch issue
Any solutions will be appreciated

I can confirm I have the same issue with mine. Very annoying.
Thanks for confirming, again showing it's not an isolated instance.
Is this issue only for Hotspots? Or any Wifi device? I ask, because I don't see a problem with my WiFi router at home.

For me it is only for open Wi-FI (no password required to connect), the tend to be public hotspots.

That underlined bit is interesting.
so it seems this only occurs with open networks ie ones that don't require a userid/pass.
otherwise you have no problems connecting when there required login is required and is saved already.
eg. your home wifi ?
some more reading led me to this post.
My G4 doesn't have any problem with the open network at my work. It connects automatically as soon as I drive in the parking lot, if I leave and come back, as soon as I'm in range it re-connects just fine.

Have we considered this might be done on purpose as a safety thing?
You shouldn't want your phone/laptop connecting to any OPEN network automatically that you haven't vetted. This is how scammers skim passwords, etc., by offering 'free' wifi hotspots in busy areas.

Not quite, it happens on open networks that I have connected to before i.e. saved and as you put it vetted.
Connecting to saved networks that are passkey protected works fine.
Yes that's right, for me the network that requires password has no problem to auto connect
And the post you linked for refresh DHCP, I tested and it doesn't solve the problem

Then there is no problem here is there ?
I also have this problem.
To clarify, my situation is for open wifi where the provider redirects you to a webpage where you click "ok" or "accept" to proceed.
The first time I connect, it's fine. But, when my phone tries to auto-connect the next day, it gives the error described. So, I have to manually open up wifi connections, view the list, select the wifi name, and connect.
So it works fine after some manual intervention, but there is a bug I think in how the G4 handles these types of open wifi connections, once they are saved in the phone's history and you try to connect again later. So there is a problem here, but it's somewhat nuanced and easy to miss.

Your description sums up the situation well.
Doing what you want could create a problem of another sort. read this.
http://android.stackexchange.com/questions/64380/stop-wifi-connecting-to-open-networks
No this is not the same.
i only want G4 to autoconnect to network I saved before, meaning the one i have used before and want to use it again.
The problem you are referring to is having android auto connect to random networks, which of course should not happen.
Also G4 currently does not connect to open wifi that doesnt require login either. Even it clear have good internet connection, it wont reconnect, which is clearly a bug

see this is where it gets tricky, that post was referring to networks set up by a telco around the city. the ssid is the same its not a random network. This is exactly what you want.
you accepted it when you were in location a, now you are at location b and want to connect. so it should connect automatically ie no different than if you were to return back to location a.
You said home wifi works, so leaving wifi on, walk out of range and then come back in range and it connects automatically. And you expect the same behaviour with an open wifi that you accepted prior.
Way i understood it is that guy is complaining about what you want with open wifi
Thanks for clarifying.
I went back to re-read the post you pointed out. OP of the thread wants to block all the open wifi hotspots with paywall. It is not because he/she used one paywall network work in location A and doesn't want to use it again in location B. OP never used the paywall network (because it charges) and doesn't want to ever connect to it again, in that case, delete it from the saved network list should solve the problem.
In fact, Op also wants to use non-paywall open wifi, which is same as what I want here with G4. We both have the same need, which is auto re-connect to known, used, and trusted network. Here is exactly G4 cannot do and clearly having a problem. As I said before, even for network that is open, no paywall, and no log in required, G4 simply cannot auto connect, and claim "internet is unavailable", which is false and need to be fixed. Furthermore, even if there is a captive login, G4 should not refuse to auto connect before informing user so. While LG clearly has no problem sending tons of notification for their bloated LG smart notices, right now there is no single notice about WiFi auto connect failure, you will only discover the problem after you open WiFI set up page.
I copied OP's own words from the other thread FYI
"here are random open wifi networks everywhere that allow my Android to connect to their network but won't give internet access because there is a paywall"
"There are a wide variety of providers like BTOpenZone. I'd like to block them all, adding exceptions if I ever find a non-paywall connection"

My phone is always connecting to WiFi connections automatically (as they come in range).
I don't want it to. I only want it to automatically connect to the ones which I specify (my home, my office...).
How can I configure to only connect to the networks which I specify?

you know, i don't have that behavior, my phone only connects to networks it remembered.
In the list of available wifi networks the remembered ones are at the bottom. If I hold down and select 'forget network' then they go away.

My list of available wifi shows maybe about 100 or more entries. How can I delete them all?
I have Cricket wireless service. I had initially installed a cricket app for managing wifi and I believe it may have added all of those wifi connections. I wonder if this has somehow messed up my phone. I have since deleted the app, but the problem still persists. :crying:
Well I guess deleting one at a time would work eventually

That clearly is not a realistic option as it would take me a very long time to delete that list. I also don't believe that it will fix the problem. Every time I pass a WiFi network it will just get added to the list again.
Just the other day, I was sitting on a bus and we were driving alongside another bus which offered WiFi to its passengers. My phone automatically tried connecting to the other bus's WiFi.
Does anyone know how to configure this, so that I only automatically connect to the WiFi networks that I specify? This is making using my phone with this version of Cyanogenmod very frustrating.
I have a question. I have "keep WIFI on during sleep" option set to "Never".
When I wake up my phone from sleep after 30 minutes or more of not using it, the wifi does not reactivate itself (it's off, no icon in statusbar), but when I go to settings, it says that Wifi is enabled. Just like in the picture below...
I want to know if this is normal or what? Happens to me on both stock and custom rom.
EDIT :
I fixed this by putting my Wi-Fi frequency band from 2.4 GHz to "Automatic" in advanced wifi settings. Htc and google really need to fix their ****!
I also disabled ipv6 in my router settings, not sure if that helped
Sadly for you, it works as expected for me. I let my phone sit for about 40 mins hoping I wouldn't get a text. Picked it up and the Wi-Fi turned on and connected right away.

This is just plain weird for me. Not a real problem, but strange, maybe has something to do with my wifi connection (router).
Thanks for the reply!
Just confirmed that one other guy that just got the phone has the same issue.

I have had the WiFi Frequency Band set to Automatic since I got the HTC 10. I came looking for this topic because of what mine does. When I wake up the screen, there is often a message on the screen "wifi has disconnected", and it will show connected to mobile data in the notification bar. It usually will reconnect to WiFi within a few seconds. But it is annoying, so I am looking for a fix, if there is one. I turned on the setting to keep it on WiFi during sleep a couple days ago, but it didn't change this behavior.
From what I am reading here, this sounds like it is common to the HTC 10 regardless of that setting. I am therefore thinking perhaps the "wifi has disconnected" message is actually left over and still on the display from when I turned the display off? But what I don't understand is that I get notifications such as incoming email and hangouts messages while the display is still sleeping. Unless those are coming via the mobile data connection. Perhaps I should try turning off mobile data and leaving wifi on to test if it still does that, but obviously leaving the mobile radio connection off is not desireable, even if that did help. Does the HTC 10 silently always switch to a mobile connection and turn off wifi whenever the screen is off, meaning that keep wifi on setting is flawed?

No. You probably have "Auto-switch to mobile network" enabled in advanced wifi settings.

Thank you for replying. The only 3 boxes I have checked in WiFi > Advanced are as follows:
WiFi Notification
Show Wi-Fi pop-up
Hotspot sign-in
All the other check boxes are blank.
So I have similar problem. When I leave the house it switches to mobile network just fine. When I come back home it doesn't auto connect until I turn on the screen. My advanced wifi settings are below with basically nothing checked.
I agree this is a serious problem and for me I have no mobile network at home and depend on wifi and hangouts for voice calls.
Just curious what firmware is everyone on? Mine is 1.91.617.1.
This thread discusses it quite a bit, mentioning different settings changes to try.
http://forum.xda-developers.com/htc-10/help/wifi-issues-htc-10-weak-signal-fail-t3368165
I tried some of these changes, and things seemed better today for awhile, until I found out my phone actually wasn't getting the internet over the solid WiFi connection to my network. :/ I had to undo all the changes so I could get back online with it.

Interesting. Mine was already on Automatic. I never touched it.
Hi does anyone know how to fix this please when screen is off it keeps disconnecting at work so no notifications come through as dead zone for mobile data! If screens left on its fine, never did it as often when I had galaxy S9 Plus hardly ever went off! Has the mate 20 x got an aggressive doze mode or is there some options in developer mode? Any help would be great thanks!
just guessing here, but look in the wifi advanced settings to see if there is a switch to keep it on all the time. If not, enable Developer Mode by tapping on "build number" in the "About Phone" section of the menu seven times, then look for the proper setting in the Developer Settings section
Go to Settings>Battery>More Battery Settings. There, enable the "Stay connected when device sleeps" option. Done

If it doesn't disconnect when on your home network then it seems it's an issue with the work network, worth asking that network admin if there are any special settings to allow your phone on the network all the time. Being in a hospital it makes sense for security purposes that they have tighter control what devices are allowed on the network, even if you have the passphrase I would think they don't want any device to connect that could pose a security risk. Works for me at home and work, have AL00, but I have admin access to both networks.

Don't think it's the case... They can do it on airports but not in hospital.. It is simply huawei + Chinese.. Global version or eu version won't disconnect.. It is probably not wifi disconnection or mobile data disconnected, but problem is sync.. There is longer interval or just sync gets killed because battery policy or threshold is long than usual.. In Chinese versions "sinc" feature missing it is there but hidden and even missing in drop down menu..
Problem is dat app is being cut off from network and sync is bit lazy...
On Eu or global versions sync si problaly set for 5min interval.. And in Chinese there is or will get killed some point
