Wifi Mystery - Can Manual Add/Connect SSIDs, But Picker Shows Blank Scan - Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl

I have a rooted Wifi Only version SMP-600, running the Broken OS and is pretty light on any other tweaks. Recently, no ssid's will appear on my wifi picker, but, if I manually type in the access point name and then password, it WILL connect and act in all respects normal. Even the notification that there are open access points will pop up, but still, the wifi picker screen is still blank. oh...my bluetooth quit working at the same time...wont go on at all or even scan for other devices.
Tried clearing cache, deleting all saved access points, going into each wifi folder in root and searching for anything out of whack (not that i would really know...), and a few other things, but one thing I'm pretty sure about...it is NOT a hardware issue. The wifi hardware IS working, it's just not disclosing the available channels. Tried Fing and Wifi Analyzer to see if they could see the access points but they found nothing. BUT, Wigle Wifi turned on my bluetooth and was able to scan and see all devices and access points...hence, not a hardware issue, no?
Anyway, please help. Not a problem at home when I know the access point name, but now it's useless anywhere else. Thanks in advance.

anyone anyone?? ...

WIFI Issue

I finally received my HTC desire today. After playing for a while, I found that it has a problem connecting to a hidden WPA2 secured wireless connection. Can anyone share some light with me here??
No probs here, tested with a couple of networks (hidden, of course)...
should install my new Linksys tonite (or on friday), and will post if anything goes wrong with that.

Hidden with WPA2?? impressive....you must be the lucky one!
sorry, WPA
I have the same issue.
I have a Draytek 2820n modem/router and my Desire will only connect to it if the SSID is not hidden (using WPA2 - that's what the router tells me).
Same problem here. At work the wlan is WPA2 with hidden ssid. Google'd the problems, and seems to be a known issue with Android.

I had a similar problem, and there is an application on the Market which is supposed to handle this. Sorry, I don't know whether it works, because finally I used SSID broadcast. I think the name was HiddenSSDI Enabler.

I've just tried HiddenSSID Enabler on my Desire and it appears to work OK. You need the wi-fi turned on to enable it but you get no indication that it is enabled. I just rebooted (to be sure) and it works. If wi-fi is off when you enter your SSID, it will tell you that it can't find it - which seems logical to me.
Thanks for the tip Jade_user.
Sorry to hijack but it is along the same lines..
When I attempt to connect to my wifi router it gets stuck on Obtaining Address.. So I thought to myself right... set up static IP address for the desire... Connected.. Brilliant... except its not.. can't get on any web pages or any thing else that requires a connection!
I have been able to connect to other wifi spots fine but just doesn't want to seem to work on my router at home! I have checked the settings on the router and all appears to be fine (never had a problem before with any of the multitude of devices that have been connected). Checked the spectrum and the wifi channel appears to be all clear.
The SSID is not hidden, the security is WEP... the router is the stock job sent by O2 (they call it O2 Wireless box II, I forget the real model name but I am pretty sure its a rebranded Thompson..). I have a similar router at another address and it connects fine on that one and both are on ASDL2 lines.
Sorry for the long post but tried to include as much info as possible! Its really annoying not be able to get on the wireless as its a basement flat and phone reception is dire to say the least!!
Many thanks in advance,
Pixie
I have the same issue, phone thinks it is connected to wifi just fine, but no data.
However, after investigating a bit more, it seems that it is the DNS lookups that fails, since in that situation, surfing directly to an ip address works just fine, but not if it requires a dns lookup !?!
Hmmm... I just changed the security to WPA and now it is working fine :S.. still annoying because now we are going to have to change all other devices over.. Might be worth a punt in your case tunedude?

Can you tell me where in the option there is a feature called "HiddenSSD enabler" just cant seem to find them anywhere. Maybe I am blind, can you share some light???

Have you looked in the Market? It's not a standard option, you need to install it from the Market - just search for HiddenSSID.

Ya found it, install it...but no effect?? dont even know if the program work. It just have the screen to type the SSD?? and then enable button. I have clicked many times on the button, but nothing happen. In the Wifi setting, I created the name but still it says out of range.
There is nothing wrong with the WIFI, when I broadcast the SSID, it work just fine. Anyway, I give up...I just broadcast them.
Just add MAC filtering as mentioned before - more secure than hidden SSID

Mobile Network Traffic despite WLAN connected

Hi,
when my HOX is lying near by PC Speakers, i can hear Internet Traffic over EDGE/UMTS excatly all 3 Minutes. (I hope u can understand what i mean)
I´m wondering about that bescause WIFI is active and connected, and i never had this with my DHD.
Due to optimizing Battery life, i disable mobile Network manually when i´m at home and have WIFI connected.
I use ARHD 9.1.0 with stock Kernel and EQS + APM + %Batterycircle + Autobrighness by jotha.
Baseband: 2.1204.135.20
Build; 2.17.401.2 CL89015
Any Ideas whats generating this traffic and why the HOX don´t use WIFI for that?
its normal gsm traffic. like if somebody sent you an sms, you would hear that sound. not sure why it didn't do it with dhd and now does with hox, but either way, shielded speakers are there to solve that problem. as for adapting your current speakers to shield them, not sure if its possible or not though.

Thanks for your Answer, but i don´t hear that Traffic if mobile Network is disabled, so i thinkt it can´t be "normal GSM Traffic".
oh i see what you mean..
might be network location services?
settings>location>google's location service.
i know the location services use wifi as well, but it might use mobile network in conjuction even if connected to wifi.. try disable that and see if it continues.

try download osmonitor, might be other apps more specific that can help, but osmonitor should do the trick i hope.
set your screen not to turn off, just for ease..
goto the connections tab, process tab will also be useful and watch it until the noise happens. you're looking for either a process, that jumps to the top of the list when the sound happens (spike in cpu usage), and then does it every time the sound happens, or a connection, that ISN'T your local or external wifi ip address, but also has similar behaviour, ie the connection is created when the sound occurs, and is then gone a minute later.. (the connection should show an app name)
if you find an app that looks like it could be causing it, then try to uninstall it temporarily to see if it fixes the issue. if it does fix the problem, the next step would be to contact the developer of that app to request a fix for it. it could however be a system process causing the problem.
failing the above, you could try the same sort of diagnostics, but with logcat instead. i don't actually know how to initiate logcat, i'm sure a google will tell you how though.
Thanks again! (i´ll hit the Button )
Okay, got that app installed.
Unfortunately the Sound DOES NOT appear all 3 Minutes when the Display is on.
When it starts and i unlock my screen i cant see any new entries in the Connectionstab.
Processes the same, but "Android System" shortly came on Top. (maybe the Display Unlock is the Reason for that?)
BTW: Why i got 2 permanent open Connections?
1. Google Bookmark-Sync (Whois -> Google)
2. Downloadmanager (Whois -> "The New York Internet Company")
Not idea what that could be.

you should be able to set the display to never turn off in settings>display and gestures
i don't think it'll be very easy if even possible to find it if the screens off (the spike would only be there for a second or 2, by the time it's unlocked etc it will have disappeared)
the other connections, first one is probably the google account sync, and not sure about download manager, maybe something got stuck, you could try clearing data for the download app, but to be honest i doubt that they're any problem anyway so probably nothing to worry about
edit: the download manager bit judging by the whois could be an app relating to that? do you have anything similarly named installed?

This is crazy - when the screen is on, the sound isnt audible. It only happens when the screen is off.
In the Connections Tab is only one Connection without my WiFi-IP, and whois shows me its a DNS Server from my Carrier (vodafone).
In the Process Tab i can see that "System" comes up on Top for ca 2 seconds, further no action.
The 2 Connections which stays established:
Clearing the Donwloadmanager Data was a Success... Thanx again.
The Connection to Google from "Google Bookmark-Sync" is still there. Gmail Sync is deactivated in accounts.
I think i´ll give it up and live with it

Is there any WiFi Error solution?

I went through google, here, and other android blogs and where I found people who've had a similar problem to mine, there seemed to be no concrete solution.
What I'm talking about is literally in front of my eyes, though I didn't know the extent at the time, the wifi \ bluetooth died. I was listening to a podcast and the wifi turned off. I had no problems that led to this, no issues with the ROM (Energy) and anything else to indicate anything was wrong. So after turning it on it would just say error, and that was it.
Like other posters who've brought this up, I cleared cache and dalvik, went to stock, went to other backups from different ROMS, and still nothing. So is there anything concrete anyone here knows about? Thanks in advance!

So as to fix this problem,some people suggest to do a Factory reset.But, it is completely unnecessary.Instead you can try the following methods, which where tested by me successfully.
1. Dial *#*#526#*#* to reload the wifi driver.If it doesn’t work, restart your phone and dial it once gain.It will work for sure.
2.There is an app “Wifi-Fixer” from android market,which claims to be fix this problem.But seriously,it hadn’t worked for my mobile phone(Samsung Galaxy Ace).But,
if you are interested, can download and try it here.
For HTC users, I have a pretty good trick which works very well.
When you have obtaining IP address problem,
1.Turn off wifi.
2.Open “Allshare”, then you will be asked to connect to a wifi network.
3.Then select the wifi network that you need to connect from the list opened.
Magically, you will be connected without any extra effort.This works 100% sure without fail.
If that doesnt work try this:
1.Dial *#*#526#*#*.Then a message will be shown “Driver loading Successful”.
2.Now Start the WiFi, it should work.
If the message “Driver Loading Unsuccessful” is shown, follow these steps:
1. Dial *#*#526#*#* again and click options button on your phone.
2. Select Rx test.
3. Select Channel >9 .
4. Click Start and exit.
5 . After some time, turn on the wifi.It should work.
It is possible you've fried your wireless card.
Can you test Bluetooth calling?
If enough heat built up for a long enough period of time both could be affected.
ie charging while on wifi using Bluetooth and a heavy CPU workload is a perfect recipe.
Okay Diablo, thanks for the suggestions but of course, it didn't work. So many times I read these threads where people are having trouble for one reason or the other and nothing ever seems to work... Now I'm that guy.
So like I said, I would dial those numbers and nothing would come up. Now I did try wifi fixer and it really looked it was doing something, but again, nothing happened.
And 9h0S7, I'm fearing you may be right... I've read the bluetooth and wifi are on the same antenna, and I can't get the bluetooth working either. A friend of mine checked the board and everything looked fine so visually speaking nothing seemed corroded or messed up in anyway.
Anyway, thank you both for your help and I continue to hope this can be fixed!
Help! No Wifi connection now...
I had the "Wifi Error" problem with my Samsung Galaxy Ace device, so tried to follow the procedure described with Allshare. It didn't work, and now my device is not able to connect via wifi in any way! I've tried restarting the phone many times and dialling the code to reload the driver, I tried to download Wifi fixer, but no method works. The phone "sees" the Wifi network, tries to get the IP address and then disconnects. I don't know what to do... I'm desperate...:crying: :crying: :crying:

Returned home from short trip, Wifi connects but does not function

As the title says, I didn't change anything about the phone's configuration when I was out, didn't download any new apps or change any settings that would interfere like this. No one else has changed my home network in my absence.
Nevertheless, most of my apps, such as Instagram, the Play Store, Twitter, Wikipedia, Chrome; almost all their requests time out. There seem to be short windows where data will load, and Instagram appears to load comments and post metadata, but no images. It's basically unusable. Occasionally an exclamation mark will pop up over my Wifi symbol in the notification center. Strangely, I can still reach my Steam and Battle.net authenticators, but the moment I try loading the Steam app, nothing comes up. It's like the device can only handle plaintext over Wifi.
All of the apps work fine over cellular data.
Also, there is a toast that appears whenever I restart my phone that says "Power On" that I've never noticed before. I was rooted using Xposed, the only modules I used were Snapprefs, Xinsta, Physical Button Music Control, and Greenify Experimental Features, all of which I uninstalled. The toast still appears with the latter two disabled. Only other rooted apps I had besides Xposed were Nova Launcher, Greenify, Busybox, and Root Checker Basic, all of which have been removed but Nova.
I am running 6.0.1 with the latest update.
Any ideas? I am still within 15 day warranty so I could theoretically return the phone (which I was contemplating doing anyhow since 10gb of functional storage is a bit too small for me), but would rather not have my hand forced, and eat into my cell data plan.
So far I have tried forgetting the network, wiping cache/dalvik with TWRP, removing the Google VPN, resetting all network settings, and a couple things I can't remember offhand now. Any suggestions will be appreciated.

First, if you want to return your device because the 16gb model doesn't have enough space, go ahead.
If it is mostly because of this WiFi issue, I wouldn't return the device, it is almost certainly the case this is some configuration issue (possibly in concert with some Android bug) which can be resolved.
Is it possible when you came home the device connected to a neighbor's AP and thus you couldn't use data, but it wasn't immediately obvious, so you ended up forgetting your own network and reentering the config, but the key was off by a little, and from that point on, it was just assumed the wifi config was correct?
When you say Google VPN, are you using WiFi Assistant and Project Fi? Have you tried disabling auto-connect fir the WiFi Assistant?
Have you tried using the old Lollipop DHCP client (perhaps your IP address got used by another device and the new Android client doesn't handle that well?) Just grasping at straws.
Have you tried turning on Bluetooth while WiFi is on? Perhaps there is a bug with them working independently of each other in certain situations.

I am 100% positive I am on my own home network and that I used the correct key. I'm not sure what you mean with regards to the rest of the 'config', I have always used the standard wifi configuration, just typed in my key and had it work.

I actually forget what it was called, it was under Settings>Wireless&Networks>More>VPN. There was one entry there with an icon. I forget the name of it, but the icon looked like a stock Google icon and I think it had google in the name. I am on Project Fi, not using any wifi assistant (at least not in Advanced Wi-Fi Settings), but when I tried to toggle that option on just now, something called "VpnDialogs" crashed, so I assume that VPN entry was that. But again, the assistant wasn't on.

I don't use Bluetooth, and trying to toggle it off/on from the control center just gives me a repeated "unfortunately, Bluetooth Share has stopped" error message.
I have decided to get the 32GB 5X since I do want more storage, but since I would like to be able to root my phone again and use Xposed, I would still like to hear any other ideas you have for troubleshooting this problem in case it reoccurs.
I reflashed the latest update to see if that would fix it, no dice. When I send the 16GB model back I have to factory reset it anyway, so I suppose I'll know if that does it.
What puzzles me is why I can load text from instagram posts that have been posted while I've been having this problem, but not images. Makes me think that maybe my connection is being super throttled somehow rather than non-functional, but my PC's speeds are normal. Perhaps some internal part is damaged? I do have a case and it hasn't taken any serious tumbles, but it has had one or two small falls from maybe 2 feet high.

It is easy to test if you have some network connection vs none.
In terminal or adb shell
ifconfig wlan0
ping www.google.com
1st command will tell you (among other things) if your wlan picked up an IP address.
2nd command will test whether you can send ping packets over your connection.
I'm sure there are millions of ways of doing the above, I just gave you one example.
Strangely, the solution seems to have come from factory resetting my router. I ruled this out initially because my other old phones were working fine on wifi, my phone is now getting WiFi again.
Now to figure out what the hell this "Power On" toast is about...

I've encountered something similar where the router runs out of NVRAM space because it has recorded too many DHCP clients, it won't hand out new IP addresses, but if you are existing or already have one, it is fine.

Hotspot device control/manager

Good morning all.
My S9 is completely stock and up to date.
In the Wi-Fi hotspot settings, there used to be an option to rename a connected device or remove/block a device but these options are no longer visible. Online instructions suggest that scrolling to "more" or pressing the three dots should bring up these options but neither work. I can see the list of connected devices but no method to manage them.
I want to block one specific device. That device won't allow me to turn off WiFi or manually save a random password without a full reset and I don't want to change the network name and password of the hotspot because that would mean that I need access all the other devices that use it to change passwords in order for them to continue working.
Samsung have been absolutely no help whatsoever.
Does anyone know how to access these (now hidden) options please?
After a bit of Googling, apparently the function was removed in the update to Android 10. This is so frustrating.
