[Q] Strange wifi issues - G2 Q&A, Help & Troubleshooting

Hey guys, been having this problem for a while but finally had enough of it!
For a start, in the wifi list in settings it doesn't show me which network I am actually connected to.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
In addition if i tap another wifi network which despite already previously been connected to it , it will still ask me for the password again, after which it keeps saying failed to connect, it wont let me connect to it
I have been getting around the problem by using WPS on my wifi router and "WPS Push Button" in the settings menu when I'm home to get it to connect to my home wifi as opposed to "BT OpenZone" every time, which is quite frustrating!
I'm rooted on stock rom , Build Number KOT49I.D80220h however this problem has been ongoing atleast since before the last 2 updates.
Any ideas/troubleshooting I can do??
Cheers amishra123

Tried resetting to factory defaults?

I haven't no. What's the best/easiest way to go about backing up before and restoring afterwards ?

LGBackup on the phone should suffice. Just make sure to copy the LGBackup folder to a safe location (like a PC/laptop).

[Q] [Solved] Can't Delete Wifi Settings

Hi.
I have a problem regarding WiFi connectivity on my G2 (LG D802 running KK 4.4.2 D80220D)
The problem is when I open Network settings page, it says that II'm connected to a WiFi Network (For Example ABCD):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
but when I open WiFi settings, It doesn't show me connected to any Wifi AP:
I cant disconnect from the connected network, because it doesnt state connected in WiFi Page, neither I can "Forget the Network"
and this is happening to all WiFi APs, not just my AP. Turning WiFi on/off didn't help. My phone is rooted, so is there anyway to delete these WiFi settings from somewhere in phone, so all saved wifi settings be gone?
Things I've done so far:
Enabling Airplane Mode (No Luck)
Restarting phone (No Luck)
Wiping dalvic Cache and System cache (Again, No luck)
Sorry for no images in post. I'm not allowed to put any link here, so attached them in order.
Update:
I deleted "/data/misc/wifi" and rebooted the phone and everything got back to normal. hoooray!!!
Anyone?
I have the same exact problem. And i am traveling now so thats a big problem for me.
Please help
Edit:
Ok i missed the update.. But i am not rooted, so i dont think i can delete the misc/wifi..

[Q] Please help

Im not sure where else to ask this. I have searched all over the internet and to no avail. But I was scanning my network with Fing (an app that shows all the devices in the network), and I noticed that my phone (verified with MAC address) had a system running out of port 12345 called netbus. In the description it said "Netbus backdoor trojan". I tried a factory reset and other things, but I CANT get rid of it. I dont know where I got it from, but im just worried about trying to get it off of my phone. Any ideas?

Can't get echo dot to update list of available devices?

Trying to get my echo dot to work with dish network (it was working but stopped) now it will not update the list of devices available for linking??
Here is what the web interface says after "discover devices"
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But it's wrong, the office box hasn't been plugged in for days a and the bedroom1 box is not found (tried re-naming the bedroom1 to office and it goes through like it's working even giving to program description of the requested channel but fails the "can not communicate with device")
I've tried un-linking the account from dish to alexa, I tried a factory resetting the dot, unplugging everything waiting 30 secs., tried changing wifi networks, tried from my tablet which rather than finding the wrong info finds nothing to link to at all.
I've de-register the device COMPLETELY, did a hard reset to factory defaults and started over, and the wrong info STILL survived, my last idea thought of while typing this is I'm gonna de-reg and link through a new amz account and see if that works, that's mu last straws anyone have any other straws?

Cannot select 4G Network mode

[Edit] Posted also in General Discussion: consider answer there if the solution is not strictly related to P8
My P8 used to be set to use 4G network, it was set in automatic mode 4g/3g/2g
something like this, if I remember correctly
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
For a test, I switched it in 3g mode, so now the settings are:
Now the problem is that in network mode selection, I have no option "4g/3g/2g". only these options:
How to revert to 4g mode? I read around that I can use Settings > Backup & reset > Network settings reset , but according to this link, it resets too many things
Here my phone infos
I assume this is a just a bug in the user interface, not showing the desired network mode
Is there a way to work around it, maybe manually editing some configuration file? or even better some hidden setting screen that I can use?
I'm on a rooted device and can use Adb (not an expert, but I can use it somehow)

G935V WiFi and Bluetooth will not turn on.

Hi, I recently bought a shattered Galaxy S7 Edge from facebook marketplace for $45..
Long story, short. When setting it up i noticed it would not let me connect to wifi, anyways i finally got to the home screen and data 4G lte works fine from my SIM card data, but i can not get the wifi to turn on nor the bluetooth to turn on.. it just switches back to off and a circle spins. in the screenshot it shows the spinning circle on wifi and the greyed out bar on bluetooth (from trying to switch on that wont work)

EDIT: So i want to know if there is any like modem file or what not i can try to flash via open to reinstall the "drivers" for the wifi/bluetooth, if that make sense? Or what do i do? Thanks in advance
I suggest you to install this [Rom][VZW_CRI1][Stock_Oreo_PreRooted_Easy_Unroot/Root][Safestrap_Preinstalled] and then unroot (tuto is in there too)
that way you will have flashed stock firmware, which will problbly solve your issue. And then jrkruse rom, which is great. You will end with a perfectly working, debloated phone
