Hi I have a samsung galaxy s7 edge SM-G935FD unlocked , have been using it for a while and use it mostly for the 4G hotspot for my laptop , I have a new wifi AC adaptor on my laptop which connects to other access points no problem, however seems that while the S7 edge will connect to a 5ghz Access point, the function of 5ghz mobile hotspot under the "broadcast channel" seems to be disabled from advanced options as it just does not appear to be there .
If i turn off wifi sharing , the advanced options for selecting the channel on 2.4ghz appears but nothing for 5ghz.
I am wondering if it is disabled in some regions for some obscure reason, and if perhaps i install a different rom that has the function available , has anyone noticed this as days of searching google i find how to's on turning on the option on the same model but the option is not available on mine.
Now Ive asked Samsung support and they were pathetic the operator didn't even seem to know what wifi AC was , let alone that i was asking about the hotspot feature rather then connecting to an access point , but really did not provide any useful information , in the end i gave up talking to them as they clearly had no clue.
On a Samsung S7 configuration page here :
http://www.samsung.com/us/support/answer/ANS00047789/
under the "configure hotspot " it clearly shows an image of the Configure hotspot Advanced options having the option of selecting the 2.4ghz band or 5ghz band , yet that option is not on my phone , and that makes me sad
I am wondering if this option can be enabled in some way with a custom or rooted rom , and what others have under advanced options and what rom / location they are running.
Hope someone can help , theres not much said about it anywhere.
thanks
S8+the same issue
I can not find my 5ghz hotspot broadcast channel option too.
I am pretty sure that it's not g930/g935 f/fd manual . I have both flat and edge version ( both exynos ) and there is no option for 2.4 or 5ghz !
My old G4 had this option to choose, but I can't in a newer Samsung S7, go figure...
5GHz WiFi Hotspot Solution
I'm using the Galaxy S7 Duos (SM-G935FD) running Oreo 8.0 rooted. This issue bothered me for a while because I had the same problem ... No option to run my hotspot on 5GHz band. In my case, I wanted to run 5GHz to avoid interference caused by my household microwave oven (which operates at 2.4GHz).
So here's what worked for me - your mileage may vary ...
First off, you have to be rooted.
Second, though there are probably other options, I strongly recommend using the app "CSC Features Expert" by Wanam (a brilliant developer).
So open CSC Features Expert, and tap on where it says "Used features only!". You'll get a drop-down selection where you'll want to select "Wifi". Now below that you'll see a bunch of esoteric options. Scroll down until you see the option "Support Mobile Ap 5 G". Tap on that, and a small window will pop up allowing you to edit the CSC feature value. You'll want to enter the text "TRUE" (without quotations) and then tap on "Save".
Reboot your phone, and you should have the ability to set 5GHz band under "Advanced Options" in your Hotspot configuration.
Hope this helps some people. ?

Hello
I am working on the same problem, and I'm on NFE port 9.0, which this app isn't working. However, I find one of these "other option", that is modifiy the cscfeature.xml file manually.
Unfortunately, there is no <SupportMobileAp5G> tag in my cscfeature.xml. I tired add it myself, under the <SupportMobileApOnTrigger> tag. It doesn't do anything.
I also download a Oreo rom, unpack it, check its cscfeature.xml. Still no luck.
So it will be so kind if you tells me which rom are you using at the moment you post this.
Thank you

Hi there. Like I said, I was running Oreo 8.0 (stock) ROM at the time. Since then, I've already sold the S7 I was using and upgraded to the S10+. Sorry I can't provide any further assistance with this issue anymore. Best of luck!
Hello,
On my s7 edge I did manage to activate the 5ghz WiFi hotspot (I used as described above CSC Features).
However: the mobile hotspot is working, yet no other device is able to see it. The other devices and the S7 edge successfully join my home 5ghz.
The one thing I am suspicious about is the number 149 appearing under the 5ghz switch - see the attached picture. I suppose this is the channel a and if I manage to change it the 5ghz mobile hotspot will be visible.
So my questions are:
1. How to change the channel?
2. Can you please recommend me a custom rom where the 5ghz mobile hotspot just works?

Upgrade yesterday morning and found already two problems... or maybe am I too dumb to use these devices?
Here in Europe we have 13 Wifi channels... my Galaxy now stops at 11. Where is the settings to change the regulatory setting? Before upgrading, all 13 channels were scanned and I can join my wifi network. I had to reconfigure the AP changing the port.
I have a screen larger than most of the netbook sold nowadays... but they seems to have removed the option to display website "regular" and not "mobile", or am I lost in the new interface and can't find again that option?

U.S. regulations only allow for 11 channels, I didn't know that the US Retail 3.1 had 13 available. Did you have OTA update or flash one of the ROMS?
What do you mean "regular"? Are sites being displayed in mobile version. You can try to change the UA Agent by entering about:debug in the address bar and then going to settings debug and UA. If that doesn't fix it, try the UA MOD by Doc in the Dev section.
I forget about the about:debug... so at least half dumb for now
The tablet I have was bought in the US and bring in italy just few days before Samsung starts selling the unit also in this pizza's country. I had no problem connecting to channel 13 until yesterday, then after the upgrade, my network is no more detected.
Hi, a few days ago, i have trouble with the wifi in my tab 4, model sm-t230nu, has not been dropped, only and maybe, i root and install a couple of apps, inclusive with the modem near, 50cm aprox, the problem is the same, every 5 or 6minutes the tablet cant connect with the wifi but the little icon of the signal still appear with excellent signal..... to resolve this problem, i need to disconnect the wifi in the tablet and recharge this.....
what can i do?
??? anybody could help me?

I have two of these devices and they both do the same thing as you are describing. They are "connected" to the wifi but they will no connect to the internet. This happens over and over and over. It can happen on both devices 7-8 times in a few hours. I called Samsung and they said it was my router. I called AT&T and they said it was the devices. I also have a Tab3 10.1 and I never have this problem, All of other wifi devices do not have this problem. It has to have something to do with the SM-T230NU. I noticed there was a software update for the device this morning so I am hoping there is a fix included.
If some others can chime in that are having the same problem with the SM-T230NU maybe we can at least get Samsung to acknowledge the issue because right now they are in denial.
I'm not getting disconnects (at least on this first day with the t230nu) but the WiFi signal strength is considerably less than my Note 3 in the same room as the Tab 4. Probably related?
I actually get total disconnects. I'll be playing a game or browsing the web and suddenly no internet connection and about a second later I see the toast message that it's now connected to Wi-Fi. If I reboot the tablet, it seems to work fine again for a while, but after a day or two, it does it again.
check build prop
I just received this tab 4, 7 inch and I am having this same WiFi connection issue. I have looked through the build prop and found two conflicting lines.
ro.carrier=wifi only
And
ro.carrier=unknown
Now the WiFi only line makes sense since my tab is a WiFi only model, but the unknown line usually means an open type data carrier. I have commented out the "unknown" line and will post back if it makes a difference.
So far it has been little over a week and I have not noticed the connection trouble since making the change.

by what do you mean by this? Did you change something on the build.prop coz I am also experiencing the same, I've been to Samsung service center and what they just did is update the software that did nothing but to do the same thing. Would you mind telling us a bit more of what you did please???
My 7" suffers from this same annoying problem. Can this be Fixed with the build.prop without being rooted?
no sorry making changes to the build prop require root.
and commenting out lines simply means to add a pound symbol to the begining of the line.
so for example
ro_carrier=unknown
will become
#ro_carrier=unknown
but i beleave the fix also requires setting your ip address to static and not automatic dhcp
Did anyone try my link? Solved my issues works like a champ now!

If your rooted use an app called build prop editor or some sort. Then just find those and set them as said in the post.

Having a very similar problem
When I connect my GT-P3110 to the internet and it says "connected" then the very second I open a game such as Nova 3 the network icon disappears and the internet stops working but the minute I go back to the home menu it reconnects to the network
this tab is rooted so I can edit the build.prop but I was wondering if this is the same issue or not
any help is greatly appreciated

No needed change wifi settings etc.... dont know if works with NU version.... wouöd give a shot anyways
I have been trying to get wifi calling with AT&T is working on my International S7 edge. I have made headway.
1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.

5. I am unsure if I need to make Buildprop changes or I am missing other system files. I was able to activate wifi calling and turn it on, but it doesn't work.

Did you ever get this resolved? So far I can not for the life of me, get WiFi Calling working on my S7 Edge exynos. Basically throws an error stating the activation failed, and never brings up the screen to enter in my emergency contact address like AT&T is supossed to re-direct you to.
The activation fails because AT&T doesn't have an AT&T wifi capable phone on your account which then allows you to activate the wifi. I have two imei's that are linked to AT&T s6 and s7. I can give you the imei. Go to att tech support give them the imei and tell them to update your account to be able to get visual voice mail and wifi calling. After you do this, they will alow you to activate it. However I gave up after a while. If you flash the custom csc, you must do it before your phone boots up after a factory reset and flash a custom rom. I am waiting as I am on Nougat now, so until ATT updates it's apps again.

Thanks, although I'm a bit confused on the steps your outlining here. I assume you're stating that I'll need to somehow modify a ROM (in this case SAC's N7 ROM for S7 Edge Exynos), and inject an IMEI? I'm not entirely sure how to do that to change the IMEI (this would be my first time attempting to do that). Then I would reflash that image, and then re flash the CSC update to AT&T? Maybe I'm not understanding, but my iPhone 6 is on my account and fully capable of wifi calling. In fact we have 2 iPhone 6s on the account. What exactly did you give up on?
Hate to sound like a newb here (although in a way... I am), but can you step me through the process so I can follow your line of thought? Appreciate the help!
So first of all an Android WiFi Calling and IPhone Android WiFi calling are different you will need to tell at&t you have an AT&T branded Android phone that has WiFi calling. This will lead at&t to add the ability to add wifi calling on your account.
Have you rooted your phone and installed a custom rom? If so then you would flash ttkg84's csc package and choose att. Which will flash most if not all the files. I got all the way to confirm my address and enable wifi calling, but it never worked.
Do not insert another phones imei into your phone, you will brick it and will have a expensive paper weight.
I have given up for now and am waiting for a full release of Nougat.
PM my I can give you am imei to give AT&T to enable video calling, visual voice mail and give the ability to activate WiFi Calling, but it's not likely to work. Some things are still missing.
You may never get wifi calling working because at&t uses a slightly different method then everyone else. I think they will standardize with Nougat.

That's what I thought.... So what about the King of Nougat ROM that's lingering out there currently? I realize Nougat is still beta, but have you tried the beta?
I haven't tried King of Nougat. I am currently using Nougat? Are you on telegram?

So... Interestingly enough. I just got WiFi Calling to work this morning...
Basically, I did the following steps:
1. No SIM Inserted into Galaxy S7 Exynos - SD Card only
2. Reboot to Recovery
3. Wipe
4. Download and Install SAC23's Full n7 ROM located here: http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358 - I did the V8 Debloated version
5. When prompted - Wipe Dalik
6. Insert SIM Card from AT&T iPhone (ensured WiFi Calling was turned OFF on the iPhone prior to removing from iPhone)
7. Reboot first time into N7 ROM
8. Go through the setup and connect to a WiFi location that you know WiFi calling works at.
9. Download a browser (Chrome or whatever) at a minimum
10. Eat a Bacon, Lettuce, and Tomato Sandwich :good:
11. Reboot to Recovery
12. Flash CSC for the N7 located here --> http://forum.xda-developers.com/note-7/development/utility-flashable-csc-selection-v1-0-t3450911 - Grab the CSC snapdragon the Exynos zip
13. Reboot
14. Status bar will indicate VoLTE enabled up at top eventually.
15. Try going to the pull down from the top, and clicking WiFi Calling option a couple times.... no dice.
16. Try going to the phone app --> Click Settings --> Note WiFi Calling is off --> Try clicking it on a few times.... you'll get an adroid app stopped working.
17. After sitting on this sceen for a few minutes, note the VoLTE dissapears, and the icons on the phone app screen (The Call Start Button and the Call End button) switch to WiFi magically.... Try making a call with 0 zero cell reception, and indeed, the call is being made through WiFI on AT&T's network.
Now.... I have absolutely zero idea what's going on with the VoLTE icon disappearing.... and the WiFI calling suddenly working. If you reboot the phone, the same thing occurs. It starts in VoLTE.... and then eventually disappears, and eventually after a couple of minutes being connected to a WIFI connection, switches auto-magically to WifFi calling.
I'll take some screenshots.

Followed the method above using Superman 1.16 and CSC selector 1.86.
Haven't been able to test wifi calling since I haven't found an area with wifi and no cell reception, but so far everything looks like it's working.
Important to note that the AT&T account probably does need to be provisioned for a G935A rather than G935F, which is done by reporting a G935A IMEI to AT&T (and not changing it on the device itself) as mentioned previously.

Hmmm, gotcha.... but if you report a G935A they typically want you to power off and power on the phone to check the provisioning while on the phone with them. And what happens if someone calls in and then tries to re-provision the same IMEI on another account? What happens to my SIM in my G935FD? Thanks!

Far as I can tell they don't check IMEIs against different accounts.
I can't say for sure, but I haven't had an issue as my phone has a different IMEI (or IMEIs--G935FD) than the one listed on my account (which reads as a G935A).
In short, asking AT&T to change the IMEI on the account hasn't affected or changed the IMEIs on my phone, or caused any problems.
As far as provisioning, I told them I was on the phone, so they called me back a few minutes later and didn't report any issues or discrepancies to me.
It'd be just as easy to tell the rep the phone isn't available though, so just ask them to change the IMEI and you can call them back later if there are issues if that's a concern.
Looks like great news. I was happy I was able to activate my 935F via AT&T (I gave them the actual IMEI and they activated it). I'm on Superman ROM and flashed ATT CSC. I get visual voicemail and the WiFi calling button, but it doesn't actually work. I'll see if I can get a valid 935A IMEI and ask them to activate again. Hopefully that will do the trick. I get a horrible signal at home, and the 4G/LTE icon is constantly flickering on and off... AT&T Video call option shows up in settings, but won't turn on... no wifi calling setting in the settings menu, just the quick settings button.
Any guidance appreciated!

Hello,
If the problem has mentioned before, please excuse me in advance.
My wife owns a p8 lite(ALE-L21C150B595). I have this problem which i think occured just right after the last OTA system update(B595).
The phone has full signal only when the selected network type is ¨only GSM''. When i choose LTE/WCDMA/GSM or WCDMA/GSM, it losts completely the signal. The signal in my place is excellent, i own a honor 8 and is always on 4G, and also the p8 lite before the problem occured, had 4G also. I tried a factory reset(without erasing the files), but the problem persists. I also tested if the sim card had the problem. I entered my sim card in p8lite and the same signal problem occured.(I could not place p8lite sim in Honor because is takes nano-sim).
As you understand, the ''only GSM'' is not problem in calls and the general phone functions, but when i turn on the data usage, the internet is very very slow(i have not even 3G!!). Any help or suggestions?
Thanks in advance
Hi.
EDIT: Having skipped the obvious the phone is Single-SIM, right? These may have a delay of up to three minutes before connecting to a 3G or 4G network. It's not a feature, it's a bug.
Maybe you just flased a ROM with the wrong channel-set or band mode for the hardware of the phone. The ROMs have a special band mode for the LTE and 3G channels and that is shown in that number behind the C (CUST number), in your case C150.
Is the phone originally a C150? Is the ROM the same C150?
If not, flash the correct ROM for your region.
Another hack may be (not working on all ROMs):
Install "QuickShortcutMaker" https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
Root will not be needed.
STOP here and rethink. This app is a mighty thing and you can do a lot of things on your phone that are hidden otherwise. Be careful and responsible, not to mess up everything and avoid being forced to a factory reset. Anyway, if you mess up something with this app, there will nothing be broken forever, just factory reset and all will be fine again, except for SIM card, which might be garbled up and rendered useless if you choose the wrong action. Be careful. You are responsible for whatever you do.
Now if you are acknowledging this and willing to go on, start that app and set search type to "simple".
Leave the search field empty.
Scroll to "settings" (or whatever it is called in your language) with the cogwheel icon.
Open/unfold this with a tap.
Now search for a line that is subtitled (tiny small letters) with "com.android.settings/com.android.settings.BandMode" (maybe the one behind "proxy settings" in the list, but this may vary)
Tap that line. The next page comes up. Change the label name of the shortcut to be made to "Band Mode" and tap "create/add"
Now you have another icon on your app screens. With this, depending on the ROM you flashed, you may now select the band mode maually.
Even if it throws an error, this does not mean it failed. This menu has just not been fully woven into the system. Check if 4G or 3G work now, this will be the only true indicator.
EDIT: And another hack would be:
Use QuickShortcutMaker to make a shortcut to a setting subtitled as "com.android.settings.DualCardSettings". It is in the list under settings, even on single SIM phones. Use this to check if the used SIM slot is correctly defined as the 4G/3G slot and data link, and correct if necessary.
good luck

Hi.
EDIT: Having skipped the obvious the phone is Single-SIM, right? These may have a delay of up to three minutes before connecting to a 3G or 4G network. It's not a feature, it's a bug.
Maybe you just flased a ROM with the wrong channel-set or band mode for the hardware of the phone. The ROMs have a special band mode for the LTE and 3G channels and that is shown in that number behind the C (CUST number), in your case C150.
Is the phone originally a C150? Is the ROM the same C150?
If not, flash the correct ROM for your region.
Another hack may be (not working on all ROMs):
Install "QuickShortcutMaker" https://play.google.com/store/apps/details?id=com.sika524.android.quickshortcut
Root will not be needed.
STOP here and rethink. This app is a mighty thing and you can do a lot of things on your phone that are hidden otherwise. Be careful and responsible, not to mess up everything and avoid being forced to a factory reset. Anyway, if you mess up something with this app, there will nothing be broken forever, just factory reset and all will be fine again, except for SIM card, which might be garbled up and rendered useless if you choose the wrong action. Be careful. You are responsible for whatever you do.

First of all thanks for your advices.
The phone is single-sim,not rooted.I have not rooted it,or flashed any custom ROM. The only updates out has, are the originals which they came ota.Its a branded phone from the biggest carrier here on Greece(cosmote). I know there is a delay to have 3g or 4g, but this one has not signal (service) at all when i change the option to LTE. i am willing to check the solution you give me, but only when i am out of the obvious and easy possibilities.As for th right band that you mentioned, i think this isn't a possibility, because it used to work properly all the previous time, and the problem occurred 3 weeks ago. I told you before that is official and i have not flash or root anything at all.I have the feeling that the problem has to do with the last ofiicial update(if it ia not a problem of the sim itself)

Well, then try to get the most recent update.
Or try the hacks with QuickShortcutMaker app.
When using this, just do not select anything that has to do with SIM, and you are on the safe side. Better than nothing.
Maybe the carrier disabled the SIM 3G and 4G features. Ask them.
It is very hard to help over a long distance. Sorry.
Hi folks, I would really appreciate some help (sorry for the long-winded post.)
I have an S7 Edge SM-G935W8 that I received as a "hand me down". It was reset to factory and updated to the latest firmware last week.
The phone was locked to Tellus and, as a SIM card is required to enable the mobile hotspot, I had Samsung unlock the phone so that it would recognize my old Bell SIM card in order to enable the mobile hotspot. The SIM card is not provisioned as I don't intend on using this phone as my daily driver and I don't require internet or data. I simply want to use it as a backup camera for my travel trailer by setting it up as a mobile hotspot using the camera to stream to my tablet using IP Webcam Pro.
This setup works relatively well but I only have the 2.4Ghz band available to me on this phone, which leads to a slightly choppy stream. It's not bad, but not great. I would prefer to use the 5Ghz band since it has less interference and thus runs faster, which I believe would yield better video quality. That being said however, the 5Ghz option is not available under the mobile hotspot advanced settings on this phone.
I then decided to root the phone, which I did without issue by enabling USB Debugging and OEM Unlock in developer option. I then successfully installed TWRP and tried both Lineage 17.1 and 18.1 since the 5Ghz does show up under the mobile hotspot advanced settings. Great I thought as the video feed was indeed better! That was until I discovered that there are issues with the video camera with these versions of Lineage whereby it works fine for about 15 or 20 minutes then the screen goes green and you need to reboot the phone in order to get the camera working again. I tried installing Footej to see if that would make a difference but it did not.
Soooo, I returned the phone to stock with ODIN and we're back to where I was before. It's a setup that works but could be better. I read that the 5Ghz band could be enabled with CSC Features Expert but you need root. OK, so I go back into developer options to enable USB debug and OEM Unlock like I did a few days ago and lo and behold, it no longer stays enabled. The option is there, NOT greyed out or anything. I toggle enable, get the message about device protection... and an option to cancel or enable. I click enable and it goes on then quickly goes off again so it now seems I can't root the phone anymore
I've scoured this site high and low, googled everythhing I could think of but I seem to be running around in circles. I can re-install the latest stock version of the firmware from any provider in Canada (I've tried a bunch) but the same always happens. The OEM unlock options gets enabled for a fraction of a second then turns off again. Can this option be forced on using ADB or Fastboot or some other method?
My goal is to root it again in order to install CSC Features Expert so I can enable the 5Ghz band in the mobile hotspot advanced settings. It also appears I can't downgrade to anything because Samsung updated the bootloader in the latest firmware. ODIN fails at installing any stock firmware except for the most recent.
Any help would be greatly appreciated.
