Samsung Galaxy S7 - SM-G930W8 - No WiFi - Samsung Galaxy S7 Questions and Answers

Hi everyone!
My son gave me his old Samsung Galaxy S7 - SM-G930W8. It has a problem that the WiFi isn't working. I've managed to root and install TWRP on it and then I tried some different ROM's with the same results, still no WiFi.
Is this a hardware problem? If so, is there a way to fix it? Or is this phone a nice MP3 player now?
Thanks!

Is the wifi toggle button present in the pull down menu?
When turned on do you then go into settings, choose the WiFi connection you want to connect to and enter password?
Your device has a mac address is this present in the settings menu or is it blank?
Settings >about phone>status>WiFi mac address

Hi @cooltt
On the pull down menu, the WiFi is shown and it appears to be active:

However, when I go into the WiFi menu in Settings, there are no access points listed:
I seem to have the same problem with the Bluetooth on the device:
Under "About Device" I do have MAC addresses for both the WiFi and Bluetooth:
However, the phone can't see my Anker speaker that is right next to it.

Problem with Wifi in a MWg Atom life or maybe just wm6

Device: Atom Life from Mwg running stock wm6 rom
since a few days ago every time i turn the wifi on and go into to select networks i dont get that screen anymore. like my home wifi works cuz it has the password. but i cant connect to other networks :S
This might have something to do with me deleting the profiles for wifi networks i dont use anymore. Thats the last time i saw the profiles screen.
i did this due to my ppc connecting on its own to a wifi when antena was off ..more like a pc wifi signal and that annoyed me so i poked around and deleted the profile of that network and others from past.
since then i cannot see even the wifi icon in the top bar all i see is the <-> arrows but with out the antenna in the background i.e <-I->
nor can i find that page where i deleted the network profiles from :S
where is it ?? i think it comes on only when the <-I-> is present.
is this a symptom of something?
u see i do not get this:

Still cannot connect to tother wifi's , with wefi not even my own :S lol
( might as well ask what backup software i should look into that will back up the rom as well since i feel i should go 6.1, or point me into the right direction for a tutorial to extract my own rom )
Update: uninstalled wefi.
icons back to before state. good.
heres what i got in my connections tab. can some one tell me if i am missing something:
band switch
beam
bluetooth
cell broadcast( what is this feature..thx)
connections
csd line type
grps setting
sms setting
usb to pc ( why does this never work- have to use wm5torage
wi-fi
wifi utility
and mwg wireless manager ( btw when u click wifi in it- it does not change status of wifi only LED turns on )

I get an Error 500 message when I try and visit the web site. It happens on my Nexus 5 on LTE and my home PC.
I guess it's just me?

Just checked, its working fine for me in California, 8:13 pm Pacific Time.
Works for my N5, N7 2012 - both running KitKat and the older HTC's running ICS - locate and ring her's at full volume.
Check your settings to see if it was turned off - power down & reboot it, try again.

Check if your Location settings isn't off!!
It's never worked for me even with the Nexus 4. Google Location Reporting is on. Location is on and is in Battery Saving mode which uses my Wi-Fi connection to locate my phone. Their app is hopeless so I now use an app called Lookout which is a lot more reliable than the Google one.
Changed the Mode to High Accuracy but still no luck locating my phone!!!!

My issue isnt that it doesnt work, it's that I can't even get to the web site. I get an error 500 message when I go to the web site. It happens if I use my phone or my computer with Chrome, AOSP browser, or Internet Explorer on my PC.

[Q] D6633 Lollipop - Location based wifi missing

This used to be in Stamina mode, but I can't seem to find it anymore. Has it moved to another setting (tried looking but can't find it) or has it been completely removed?

It is not missing in D6603. Settings : WI-FI : press the tree dots that are showing in the upper-right corner : Advanced : and there it is.
Do you mind telling me where you can find it there coz I seem to overlook it.
Screenshots from advanced in the wifi settings.
I don't see any location based wifi options here.

Also according to Sony, they removed this feature: https://talk.sonymobile.com/t5/Xper...out-Lollipop-BALTIC-GENERAL/m-p/959335#M24468
Instead you can use Smart Wifi Toggler (or any other app, they all share the same idea). It works basically well and SWT has as well an option to prefer 5Ghz WLAN.

I have wifi-o-matic (similar function), which I used before I had the z3, however trying it on the z3 it seems to open the wifi at random points and never closes it.
Smart Wifi Toggler works properly after some learning phase. I can see Wifi switched off, however the power history shows it all the time on.
Seems Sony got rid of "location based wifi" because they think Google's own scanning always available option has been improved in Lollipop. I very much doubt that.
If wifi matic doesn't improve, I will give smart wifi toggler a go.
I really liked the fact that Sony had baked in the wifi option into their rom, so was slightly annoyed that they removed it with the lollipop upgrade.

Bluetooth creating constant notifications

So with bluetooth on, I get a constant notification whether a device is connected or not. This is all after the MM upgrade.
Steps already taken:
- Verified reminder is turned off in accessibility.
- Cleared cache.
- Removed all BT devices
- Factory reset.
PLEASE HELP
@jasong127
Try settings > wireless and networks > nearby device scanning > off.
Let me know if this works. It uses BT even when off. I turned mine off long ago. Never had your issue and unsure if this may solve it.

That was already off. I think that when my car (chevy mylink) was connected, there's an option to "Allow Contact" or something like that. Problem is, when the truck is no longer connected, all the other options move to off, except this one.
Happens with one other device too (my home phone system). I have to unpair them and it stops. Pretty much seems like a bug to me.
I will have to test this on my ford transit the next time i use it. I do know it always resets the 911 link, which is annoying.
I'm having the same issues. Just did a factory reset and have not paired any bluetooth devices. But the minute I turn on bluetooth I start getting notifications. Help before I flush my phone.
Samsung Note 5 with Marshmallow update.

Did you have items at one time that were paired? The way I found out the solution is to unplug ever BT device in my house and start one by one. BTW, I have 1 home phone, 3 speakers, and a computer that all use BT. Turned out to be the home telephone that was the cause of it.

Question Xiaomi 13 - Wi-Fi portable hotspot MAC address (BSSID) randomication

Good day.
I have the following problem.
My Phone is Xiaomi 13 (global version). Codename is "fuxi".
My rom at the moment is stable "xiaomi.eu_multi_FUXI_V14.0.24.0.TMCCNXM_v14-13"
Please be advised that every time switching on the Wi-Fi portable hotspot (for internet sharing), the MAC address (BSSID) is changed in the phone.
And the problem is Wi-Fi adapter (TP-Link TL-WN725N v3) in my car (Kia Sorento Prime) recognized it as different hotspots, and therefore not connects automatically. I have to mannually connects to new hotspot everytime. Photo and screenshots attached.

FYI, my previous phone Xiaomi Mi6 had a static BSSID of portable hotspot and the car always connects automatically which was great.
I have been looking in settings for everything related to Wi-Fi for a long time and found the following:
1. Developer options > Wi-Fi non-persistent MAC randomication
This option doesn't work! I tried ON/OFF - no any difference.
Screenshot attached.
2. Password & security > Privacy > Protection from Wi-Fi probe requests
Alternative name is "Wi-Fi Probe Protection". I've googled what is this and found the following: "XDADevelopers says that the feature appears to “randomise a smartphone’s MAC address so that the actual address is not shared with the WLAN router with a probe frame,” which is basically a request from a smartphone to scan available WiFi networks in the vicinity"
This also can be a sollution, but the problem there is no possible to disable this option. How to switch it off?
Screenshot attached.
3. Just FYI, real device mac/randomized mac can be configured in Wi-Fi saved networks only.
However in case of portable Wi-Fi hotspot (for internet sharing) - there is no such option, always randomized mac.
Screenshot attached.
Pls check on your side and fix if possible.
Pls revert with your comments/sollutions.
Many thanks in advance,
Hi, i have never had issue with this, but for second question, did you try disabling MIUI optimisation? Maybe it will then allow you to disable that option.

Hi. There is no "MIUI optimization" option in the developer settings on Xiaomi 13 (xiaomi.eu rom).
Look at screenshot.
