I currently finished an app (for non-rooted devices) for sharing files in local network. I these are lessons learned: It is possible to run an SMB Server on Android without root access (on non-privileged port).

You can check the internal Android log logcat to see WiFi connectivity changes (and many different events) from the last few hours or so. To do that, you'll have to enable USB debugging, download ADB, install an ADB driver for your phone on your computer, connect the phone with a USB cable and run this in a terminal: adb logcat -v threadtime ...

So it seems the problem was with the settings of the device. Having a Screen Lock (even if SmartLock is enabled, and you are in a "safe location") disconnects ADB on device idle. Only way around it for me was to disable the device screen lock.

why don't you try to get your phone back to the factory settings. i would suggest you to back your data prior going ahead with Factory Reset.

This is an old question, but I had the same issue driving me mad, so in case you did not find a solution, this is worth trying. I do not have a solution to permanently forget the network, but you can disable 5GHz on your phone, if you never need it. Go to settings, wifi, advanced and find the WI-Fi frequency band. On my HTC phone, I can select 2,4 GHz only. ...

If you would like to send and receive SMS messages over Wi-Fi, I would suggestion using Google Voice (Now integrated into Google Hangouts). You will be able to send/receive SMS free of charge (As long as you are using Wi-Fi). I have done some quick Googling, and didn't see anything that says it doesn't work in Canada. Give it a shot and see if it works for ...

I don't know about Canada, but here in the UK some carriers have apps that let you use your WiFi connection to send texts and receive using your normal phone number. I'm not sure about using this overseas but you could probably use a proxy (like Hola) if this is blocked. Even if an app exists but you cannot receive texts with it then this is generally free ...

If you want to see all available networks on the PC over your phone, I can think only one solution. Phone on screen.

Thanks to the Community bot bringing this back up, figured I would answer it. As a matter of fact I fixed this very problem on my coworker's tablet today. What I did was download the factory image, extracted the modem.bin file and flashed it via odin. No root required and this method will not remove any personal data from your device. Just need a PC, Odin, a ...

In Wireless options in your Samsung device. Click on options (Overflow-icon) and click Advanced. After that you'll see an option called "WiFi timer", click on it and uncheck both check boxes.

Wifi credentials are actually not stored very securely at all, (plain text!), but in a system folder, meaning that only a rooted app could access it. Google's backup is your best bet. It's stored in the data/misc/wifi/wpa_supplicant.conf file, for the record. If your phone is rooted, there are apps like Wifi Key Recovery and Wifi Password Recovery that ...

If you've never connected your phone to the computer before, you may be out of luck. Since the later versions of 4.X, (I think at least JB 4.3), you must authorize the host computer to connect via ADB, which will popup the first time you connect with USB. When using Wifi, this authorization MUST already be established, or it will not accept the ADB over ...

I have not tried this myself, but there's an app named ADB Wireless (no root) which, as the name suggests, claims to make this possible without involving root: This app is for developers wanting adb access over WiFi without rooting your phone. … *** NO ROOT REQUIRED *** Usage instructions can be found on the app's playstore page – looks pretty easy ...

This feature is built into Google Services, although my experience is that it sometimes struggles when moving to a new device or if you have multiple devices.

I had this problem recently and solved it by removing old saved networks in the WiFi settings. I found that there were a huge number of networks with names that were strings of letters and numbers. To remove saved networks open 'Settings' and choose 'Wi-Fi' (and wait for it to load). From the 3-dot menu choose 'Saved networks'. You should see a list of ...

We have the same problem, but now I discovered the root of the problem. If you are connecting to a wifi with weak signal, or a wifi with many devices connected, then it is the cause. Whenever I tried playing games with a wifi with weak signal and many devices connected, it keeps disconnecting and connecting because our phone might too weak to accept wifi ...

The app that makes calls to this site from my phone is the "Sprint Connections Optimizer" which is my phone company's network spy. If your service provider is Sprint then this is definitely your problem. It was tracking all my wi-fi connections in hopes of creating a dynamic map of networks to the benefit of Sprint, from which to steal bandwidth rather than ...

You can turn your device into a Wifi Hotspot (there is an option in the general settings, usually with the other connectivity settings). Generally, you will need to pay your Cellphone provider to allow you to use this particular feature (although there are ways to get around this - but that is another thread). Bottom line, there is an option in the ...

I can't seem to find a manual for the unit (the website doesn't properly link to the "Manual&Download" section from the header, and the "Support Center" link doesn't do anything at all), and since it doesn't mention anything about a WiFi antenna adapter, it's hard to say one way or another with any level of confidence. That said, it may be possible. It ...

As you say that the problem exists only on 3G and not on WiFi, this is probably because of some problem with the Access Point of the your network provider. I faced a similar issue sometime back which was because the default access point had a proxy which didn't allow SSL Tunneling. After removing the Port and Proxy from the access point, this problem got ...

I resolved this. The solution seems a little bit hacky, but it worked. I unplugged the USB cable, turned on the Wi-Fi, enabled the USB tether option, then plugged in the USB. When I plug it in, it shows the message Wi-Fi is turned off when USB tethering or Mobile HotSpot is active. To turn on Wi-Fi, please turn off USB tethering or Mobile HotSpot. and ...

This seems like a simple-ish fix. Assuming you are rooted, open a root-ready file manager, and go to /system/etc. Find a file called hosts. Go into it, and delete it all, other than the first line, which should say: 127.0.0.1 localhost (if it does not, change it to that) Then you should be fine (May need reboot) If you are not rooted, go onto your ...

In order to do that, I'd recommend the app Intercepter-NG. It's a bit tricky to use, and is known to generate false positives in anti-virus software, but it seems to be the only choice.

I found out that disabling the AFwall+ firewall solved my problems. Now everything works. This has worked with the previous provider, and I don't understand how changing the simcard can result in this.

The "3g tethering" shares whatever Internet connection you're using over USB. So, if you're connected to wifi, tethering will share the wifi connection over USB. If the wifi disconnects the phone will automatically switch to sharing the 3g connection over USB. For example, if you connect your phone over wifi, than connect your phone to your PC over USB and ...

If its only happening for your router then I think it's because of your SSID name or password. Maybe they contain some uncommon characters. And maybe during boot CM is unable to resolve them correctly (characters not available in the encoding used for saving and reading the file), causing the loss. Once I used the ¥(Yen) symbol in my password and my friends ...

As mentioned in the accepted answer, you need to have root access. Then download an app called Wifi password and grant it root access. It will show all the saved Wifi passwords in your phone. To make sure that the app is not considered for other purpose(s), the app's author has mentioned: This app is not a Wi-Fi password cracker. It just shows ...
