Maybe a daft question, but is there any hack to enable 5Ghz hotspot broadcast in Sony’s official MM rom? Referring here to an option available for other brands at Settings-->More-->Tethering & portable hotspot-->Portable Wi-Fi hotspot settings-->Configure Wi-Fi hotspot. For whatever reason, seems Sony has decided not to provide ap config option of 2.4 or 5Ghz in MM.
Can confirm, by the way, 5Ghz broadcast works in various Cyanogenmod 13 roms available for the Z3 (all of which are too unstable for daily use however). Did only limited testing but speed difference was noticeable when tethering.
Thanks muchly.

Hi folks,
Just updated my P6210 to Jelly Bean (KIES_HOME_P6210XXMD3_P6210OXAMD3) and now it won't see any 5ghz wifi. Connects just fine to 2.4ghz. ICS had no problems seeing that there were 5ghz networks and connecting to them.
I've done a lot of searching and it looks like this issue has come up on other devices as well. People have recommended everything from doing a factory reset and suggesting it will start working again. I've also seen folks say this happens if you don't clear cache and factory reset before updating the firmware. Nothing has worked for me.
I've gone back and reloaded ICS and 5ghz immediately works again just fine, so the issue is obviously something to do with the Jelly Bean update or somewhere in how the update is loaded. I've just cleared cache/factory reset/updated to jelly bean again, and the 5ghz networks are gone again.
Apologies if a clear explanation is out there already; I haven't been able to find it.
Is anybody able to help me understand exactly what is going on and if it is possible to get the 5ghz wifi working under Jelly Bean on the P6210 without rooting the device?
Thanks very much for any help,

What country are you in? The current update is a UK ROM, if you are in the US, it may not see all the wifi channels properly.

I am in the US and the device has been configured for US for language, etc... Wouldn't they all need to have visibility to all frequencies for when folks travel with their devices or is it generally accepted that WiFi may not work as expected when you travel abroad? I don't travel much so I have no experience with that.
Thanks very much for the response. I really have no idea if that might impact WiFi access.
When I initially updated from Honey Comb to ICS, it was a European firmware that was available first. I had no problems reaching 5ghz wifi with that firmware. I did eventually update again when the US firmware came out, however it was just because it was available and not to address any deficiencies.
So far... here's what I've used:
Honey Comb - Factory Installed - 5ghz & 2.4ghz worked
ICS - United Kingdom / Ireland - P6210XXLPN/P6210OXALPN - 5ghz & 2.4ghz worked
ICS - Cellular south - P6210UELPC/P6210XARLPC - 5ghz & 2.4ghz worked
Jelly Bean - United Kingdom / Ireland - P6210XXMD3/P6210OXAMD3 - 2.4ghz works but no 5ghz
ICS - Cellular south - P6210UELPC/P6210XARLPC - 5ghz & 2.4ghz worked again (downgraded)
Jelly Bean - United Kingdom / Ireland - P6210XXMD3/P6210OXAMD3 - 2.4ghz works but no 5ghz (even after clear cache/factory reset, etc.)
again... appreciate the thoughts.

more info: "WiFi 5ghz Auto (DFS) channel setting not compatible after upgrade to JB?
Update:
I poked around more and found
"Issue 37482:Galaxy Tablet ICS 4.0.4 Update Disables 5GHz Wifi"
(https://code.google.com/p/android/issues/detail?id=37482)
regarding the same issue but with ICS 4.0.4 on a what is only identified as a "Samsung Galaxy tablet"
There was a response noting a similar experience and suggesting that the OP change their 5ghz channel setting on their router from auto to 36 as this resolved the issue for the responding poster.
Well... it also worked for me.
So the issue now is redefined to:
"WiFi 5ghz Auto (DFS) channel setting not compatible after upgrade to Jelly Bean???"
The issue poster had this happen when they updated to 4.0.4 (albeit we have no idea what device they were using) while 4.0.4 worked fine for me. I run into the same issue when I update to 4.1.2.
Anybody have any idea what is going on here? Does anybody have one of these working with 5gh Auto (DFS)? Any guesses what would change between the 4.0.4 firmware and the 4.1.2 firmware for this device that would require a change to the wifi settings on the router?
Samsung Model GT-P6210MA w/ Jelly Bean 4.1.2
Cisco (Linksys) WRT610N w/ firmware 2.00.01
Router Config #1
5ghz Wireless Settings that don't work (P6210 doesn't even see the 5ghz network when scanning)
Network Mode: Mixed
Channel Width: Auto(20MHz or 40MHz)
Wide Channel: Auto (DFS)
Standard Channel: Auto (DFS)
SSID Broadcast: Enabled
Router Config #2
5ghz Wireless Settings that do work (P6210 sees the 5ghz network and connects just fine)
Network Mode: Mixed
Channel Width: 40MHz only (can't be auto if you want to select the wide channel)
Wide Channel: 38 (maybe others would work, too... haven't tested.)
Standard Channel: 36-5.180GHz (can't be left at auto once other parameters are changed)
SSID Broadcast: Enabled
I'd be interested in any explanation why this is happening. Thanks very much for any help.

It's not a router , or even software issue, its probably a parameter in the Android system/build.prop file that is hardcoded to GB or UK, since this is a UK release.. This would tell the drivers to use UK wifi channels instead of your chosen local. and NO the channels are not the same in the US as in GB/UK, some are the same and some are not the UK has several channels that are not used by US routers , not permitted by the FCC and vice versa..., That's why forcing your router to channel 36 or 1 might work while auto might not work or randomly might work depending on what channel your router finds is clear..
Remember these first single country releases by Samsung are done as really a test or beta. It helps find problems which will be fixed in the broader releases.

No problem, If i were near a 5ghz router right now, I'd check it out and find the problem, but Im not.
I haven't experienced a problem yet running JB on the 6210 connected to the 5 GHz AP on my router.

Like I said, if its a hard coded parameter in one of the build files, like build.prop... it will tell the drivers to use a UK configuration in which case they will not even see some US channels. It won't matter what you set your locale in settings to... For example US uses 802.11G channels 1-11 only whereas other parts of the world use additional channels up to 14. Same applies to 5ghz, so it could randomly work or not work depending on what channel your Wifi router happened to working on. And if you Wifi AP is doing auto channels, it could work today and not tomorrow.
See here for additional info

Alright, first let me say that I have had zero issues with this tablet until I upgraded to MM.
For some reason, I am having constant issues with the Wi-Fi either dropping, or changing channels. If I set the Wi-Fi to 5Ghz only, it will eventually switch over to 2.4Ghz. If I set the wireless to automatic, it will constantly switch back and forth between 2.4Ghz and 5Ghz. Setting the wireless to just 2.4Ghz still results in random drops.
So far, I have experienced this issue on all of the major MM ROMs found here in the NVidia Shield section. I event restored my tablet with the latest image from NVidia.
Is this just an inherent issue with MM on the original shield tablet? Am I going to be stuck using 5.11?
The only thing I haven't done is flash back to the original stock image and do OTAs back the latest MM update.
Any help would be appreciated.
I agree, wifi on lollipop was miles better. I also think lollipop was better on the whole. I'm on stock unrooted.
Setting the "Wi-Fi frequency Band" to "5 GHz only" shouldn't drop you to 2.4 GHz. This setting works perfectly for me as setting it to "2.4/5GHz only" results in the other band completely shut off.
If your SSID is identical for 2.4GHz and 5GHz, then yes, it can switch back and forth. However since most Wi-Fi clients are too stupid to know when to switch over, it is highly recommended to use a different SSID for 2.4 and 5GHz.
On Lollipop, there is an Android bug (it affects my phone too) where if you have SSID and SSID-5G or SSID_5G (and perhaps others), even if you never joined SSID, it'll occasionally drop the 5GHz connection and connect to 2.4GHz. This is apparently fixed on Marshmallow as my LTE tablet has remained connected to 5GHz since the update.
At least for me, my WiFi experience drastically improved with Marshmallow. So my suggestion is to make sure the 2.4 and 5GHz SSID's are different and check for interference from the neighbors using an app like WiFi Analyzer or NetX. I recommend NetX over WiFi Analyzer as it can also show you WiFi SSID's that span 40MHz.
Also note that your own home devices can also cause interference. The Roku box w/ WiFi Direct is notorious for this.

Having the same SSID for different frequencies should never be a problem. As a system administrator, I have never run into an issue such as this, unless it you have your device set to "automatic" so that it can swap back and forth between the two different bands. If I set the radio to 5Ghz only, then it should stay on 5Ghz, and vice versa with 2.4Ghz.
The issue appears to be something with MM and the original shield tablet. I reconfirmed that flashing back to the LP image I have no problems with the Wi-Fi at all.
I guess I'll keep plugging away at trying various things until I get this figured out or someone else points me in the right direction.
Just got my brand new replacement tablet from Nvidia from the battery recall. came loaded with 5.11 and zero wifi issues. I updated to 6.01 and boom! wifi issues. That means I have two tablets with the same issue. Something is up with 6.01 and the original shield tablet.
Sounds like an incompatibility with your specific network setup and the SHIELD Tablet/Google Marshmallow.
I have two SHIELD LTE Tablets both running Marshmallow 6.0.1 and I have zero issues. I find the 2.4GHz/5GHz only modes work as intended. However my 2.4 and 5GHz SSID's are different, whereas you apparently have the same SSID's for both bands.
For an experiment, I created a single identical guest SSID for the 2.4 and 5GHz networks and put the tablet in 5GHz mode. What I noticed is that 5GHz only does indeed fail occasionally, but the 2.4GHz behavior is interesting. It will only pick up all SSID signals for the single 2.4GHz channel the Guest SSID is associated with, so in my case all 5GHz channels and only Channel 1 of 2.4GHz. After a few minutes of usage, the tablet seems to go back to 5GHz only mode and the Channel 1 2.4GHz SSID signals disappear. Similarly, If I put the tablet in 2.4GHz only mode, then it will also occasionally pick up the single 5GHz channel the Guest SSID is associated with, so all 2.4GHz channels and only Channel 149 of 5GHz.
If I have my tablet connected to an SSID that is different on both 2.4/5Ghz bands, then 2.4/5Ghz only modes work as intended.
So yes, I can confirm that if you have an identical SSID for 2.4 and 5GHz modes, then the 2.4/5GHz only mode will not work properly under Marshmallow. The suggested workaround is to have different 2.4/5GHz SSID's.
Here is my question. How did I go from having zero issues on every other Android OS before marshmallow, but now this is an issue? If I load an older rom based on 5.11 onto my tablet, I don't have a single issue. To me this points to an issue with MM

Yes, we've already established and confirmed that there is a Marshmallow related bug with your specific use case. I have provided a workaround, which is to create a separate SSID for the 5GHz band. You have also provided a workaround, which is to downgrade to Lollipop. It is your choice to make.
You don't sound like somebody who understands software development. Basically, with every major Android OS release, Google can significantly change the underlying code which can introduce bugs. NVIDIA then takes that code and tries to make it work with the SHIELD Tablet which can introduce even more bugs.
There is a programming joke sung to the tune of "99 Bottles of Beer":
99 little bugs in the code.
99 little bugs in the code.
Take one down, patch it around,
127 little bug in the code...

Without a secondary Marshmallow device, I cannot confirm if the problem is on Google's end or NVIDIA's end. Nevertheless, I suggest reporting it to Google and NVIDIA. At the very least, Google can fix the problem before Android N is released, and maybe NVIDIA can fix it for a future Marshmallow release.
While I am not a programmer, I work with several programmers and do testing of software on a test system before updates are pushed out. I guess I incorrectly assumed NVidia would do the same.
Now, I've tried multiple times based off of CM and AOSP, in addition to stock (all MM based) and still have this issue, so I would assume it's an issue on Google's end.

Honestly, this is an edge case that is rather difficult to diagnose and wouldn't even be detected under normal testing conditions. It's quite unfair to say NVIDIA didn't do any testing in this case.
I suggest submitting a highly detailed bug report to NVIDIA so that they can reproduce the issue. If NVIDIA fixes it and it is determined it is an issue with the base Android OS, they may submit the patch upstream to Google so hopefully it won't be an issue with future versions of Android.
I'm using my OPO, unlocked/rooted/latest stock rom, as our office phone. It's connected to a desktop phone via bluetooth. Problem is, when we get calls, the bluetooth interferes with the connection to the wifi extender, and the extender loses connection. I want to use 5ghz hotspot on the OPO, but even though I can select it when creating the hotspot, it doesn't really broadcast in 5ghz. It's still 2.4ghz. I can verify with wifi analyzer app on another device.
Anyone else get 5ghz tethering working? How about another rom, is 5ghz tethering working on other roms?
For some reason XZP does not support 5GHz hotspot like other 6.0+ devices.
I tried to use KEHAI but this app just simply broke my hotspot, you can connect to the 5GHz hotspot but cannot access to the internet...
So the question is: Anyway to enable 5GHz hotspot on XZP?
Same on xz1
Did u solve this problem man? Same problem on xz1, it's really lame that also 200€ Huawei phones have this 'feature' but an ex top don't phone doesn't...
If i turn back on Android 8 will this feature be available?
Dear All
I own an android phone running Android 8.1. I looked at everything inside WiFi Setting but I can't find an option to selection only 2.4GHz or 5GHz frequency. Compare to my 10 years old phone runing android 4.4.2 which has an option for 2.4GHz or 5GHz. Is there any App that help to get this option enable or any workaround? My workplace use Band Steering which 2.4GHz and 5GHz use that same SSID and my phone always connect to 2.4GHz. I have to turn wifi on/off a few time to connect to 5GHz.
What radio bandwidth actually can get used depends on both the phone's hardware and the Wi--Fi network provider.
You can run this app to see what is possible:
https://apkpure.com/wifi-band/com.igorlazunna.android.wifiband
I'm no doubt Both of my phone and WiFi AP support 5GHz(Dual Band).
AFAIK Android OS has some algorithm for choosing the best Wi-Fi connection. I don't know what it is. But I think it tends to prioritize faster Wi-Fi networks over stronger ones.
5GHz is always faster than 2.4GHz regardless of signal strength for my experience so I just want my phone connect to 5GHz unconditionally. With my old phone, when I set to 5GHz only, it won't connect to any 2.4GHz event if 5GHz is not available. That's my goal.
