S6 doesnt show unknown wifi networks

Hey guys...

i have a problem with my 920F... it doesnt show any unknown wifi-networks, it only connects to known ones.
"Wifi overview 360" app finds them all, but not android stock wifi app. Any idea which systemfiles i should check? (i have root)

Thanks.

Lost LTE and internet access on some Wi-Fi networks after flashing Cyanogenmod

This is the first help post for anything tech-related that I've ever posted- I'm usually good enough with Google to fix my own problems, but this one has me flustered.

Until yesterday I was running DigitalHigh's GPE ROM but decided to give Cyanogenmod another try after some persistent lag issues. Everything went fine during the install until I noticed that I was stuck on 3G no matter what I did- airplane mode, reboot, clear the cache, try to update APN settings, etc., nothing helped. Additionally, while the phone will connect to my home wireless network, it has a ! next to the connection symbol despite my being able to use the network with my laptop. The funny thing is, this only happens with some networks. Neither my home network nor the network at work will give me internet access, but if I plug an ethernet cable into my laptop and create an access point that way, I'm fine.

Here's what I've tried so far after scouring these and other forums:

-Reverted back to the previous ROM
-Flashed new firmware
-Flashed two new kernels
-Tried every different APN setting I can think of
-Popped out my sim card, waited a bit, and popped it back in
-Rebooted countless times
-Cleared every cache I can think of
-updated TWRP

There's probably more that I can't think of off the top of my head as well. Does anybody have any idea what on earth has happened to my phone?

How does a single-SIM MVNO on mulitiple networks work?

So if you get straight talk, you have to select from 4 SIM cards to pop in, and that activates your phone on that particular network... I get that. Lately, however, I've seen multi-network MVNOs arise (like Defense Mobile, ROK Mobile) that only use one SIM card. How does a single sim card authenticate between several carriers? How does a single sim multi-network MVNO handle that extra step Verizon usually requires of authenticating the individual phone's IMEI with it?

Please help me understand.
Thank you.

Two identical WiFi notifications for click-through-UA free WiFI networks

I have Startbucks WiFi added to the list of WiFi networks on my S2. As many of you probably know, Startbucks WiFI requires users to click through an "Accept and Connect" screen before allowing them to access Internet. Now, I notice that when I walk into a Startbucks with my S2, it pops up two identical standard notifications about being unable to access Internet and WiFi network requiring user attention (or something along those lines).

So, why am I seeing two identical notifications every time? Is this something about my setup? Or is it just a quirk of Samsung version of the ROM?

[Q] How to make the Sprint HTC Desire 510 useable on GSM networks? (with sim card)

Hello, I have the Sprint HTC Desire 510 version. Im from Israel, And I've managed to get S-OFF and unlock the device with the Sunshine APK.
