I've done more googling than I'd like to admit..
I thought selecting "5Ghz preferred" in hotspot settings would broadcast both frequencies and nudge 5Ghz capable devices to that band but in practice none of my 2.4Ghz devices are able to detect the network at all. I even restricted my PC to 2.4ghz which then couldn't see the AP anymore either. I keep having to manually change bands when the need arises. Anyone know what's going on, a way to confirm both bands are broadcasting, or a fix for this?
Magisk rooted edge (2021) trying to avoid bootloops but had so many already it's whatever.
also, anyone know of a good way to modify TTL on Android device hosting the mobile hotspot? I tried iptables but I don't think our kernel supports mangling natively. Perhaps someone can mention if they've tried any compatible kernels?

broadly described as, a kernel that supports A11, TTL mangling with iptables, and doesn't break any other functionality of the edge 2021. ill update if my own research ends with success on the TTL part.
As for Hotspot issue, I'm still lost on how to make it appear for 2.4ghz devices. I've read, and if im understanding correctly, that devices that use band steering advertise differently and 2.4ghz devices may not detect it at all if passive scanning. idk if that's my issue because none of my devices, inc. my PC(when set to detect 2.4ghz ONLY) see the hotspot network when set to "5ghz preferred". Unless every single device i own scans passively(unlikely) i think it's something else.
Haven't had time to dive deeper, i.e how to make sure my travel router scans actively instead of passively, I'll get to it eventually, forgive my ramblings

WTF!! Anyone know hot to get the tablet to connect to a network with SSID hidden. Tried 3 routers, no deal. Running vegan 5.1, would swith back to TNT if necessary.
Thanks.

I had a similar issue. I have two routers: The westell, it connected to no worries. The Cisco/Linksys I couldn't connect to to save my life. As soon as I let the ssid broadcast, it picked it up and connected. I can even re-hide it again, and it will connect.
I've tried a few ROM's on my Incredible, and the same thing. It connects to the Westell, no worries. But I have to broadcast the SSID for the phone to connect to the Linksys. It turns out Android is somewhat well-known for this. and I believe it to be a system issue, not specific to any ROM or branch.
In reality though, NOT broadcasting the SSID doesn't add much in the way of privacy. A script-kiddie with a WinMo 5 fone can find and connect to them. I used to use my Wizzie to find and connect to WiFi networks when I traveled. Just make sure you are using a secure connection like WPA2 or something.
Tell me about it it drives me insane!!! I'm using a dlink dsl-2740b with/ without MAC filter and i can't get it to find my hidden SSID.
did the kernel mod 2.6.32.28 - from pershoot still no go. Anyone else found a fix?
I'm running an old Linksys WRT54v1.1 with DD-WRT installed...
Non-Broadcast SSID, MAC Filtering, WPA2 -- no issues...
Worked for me right away....on all ROMs (so far) -- Stock, TnTLite, & Vegan...My phone has Cyanogenmod so I'd assume it will work as well...
I'd highly recommend DD-WRT as a new firmware for your Cisco/Linksys if it is a supported model...

I know it's totally not the point of this post but, exactly.
It in fact creates more problems than it does any type of good on any level at all because it makes it more trouble for you, the user to connect to your own network. Some chipsets have issues connecting to hidden SSIDs as well, as shows with the Tablet. Phones can have the problem too. Computers less so just because of the detailed configurations of the software.
You don't even have to be a script kiddie or hacker, there are easily downloaded, well known tools that show hidden SSIDs, along with mac addresses of any and all routers and also which sniff wifi signals. So pretty much anyone that knows more than how to check emails can get into your network if they need/want to and you're not using WEP. WEP is of course only a step up and still simple to get into with just that much more effort (not much, at all).
In these days and times in terms of privacy, if you're not at the very least using WPA with AES then just go ahead and leave it open.
I just got my 64gb G6 Edge and am experiencing major WiFi issues with the device. My devices wireless will disconnect randomly from a strong signal and I have personally observed it disabling and re-enabling the wireless by itself.
Also once disconnected it no longer sees ANY wireless networks no matter where I go even though it shows the "scanning" circle spinning and I know that there are strong known wireless networks by me. If I manually toggle the WiFi off and then on again, all wireless networks around me are detected again and if any of my known networks are present it will automatically connect. However after a period of time this connection will disconnect and I have to do the process over again.
I have already made sure that 1.) Smart Switch is turned off. 2.) Keep Wi-Fi on during sleep is set to Always. 3.) Always allow scanning is enabled.
I have also tried disabling the WiFi Power Save mode [*#0011# and click on more>>WiFi>>"WIFI Power save mode"] this too resulted in the same behavior.
I've only had this phone for a day and a half, not rooted, already cleared cache partition from stock recovery etc. I haven't tried a factory reset yet (not sure how much good it would do), but at this point is there anything else I should try or is the consensus I need to get my phone swapped out?
**Update** So upon extensive further testing it seems that my wireless issues are caused by issues connecting to the 5GHz band on wireless access points that use bandsteering in that both 2.4GHz and 5GHz use the same SSIDs. This is a MAJOR problem for me as I encountered this at my place of work and rely on wireless heavily not to mention my phone heavily for wireless testing. There are no "Advanced" wireless settings for selecting which band to use either.
I really need some suggestions in order to try and get this problem solved or I may have to switch to a crappier phone just to have functional wireless.
I had something like that happen too, but I only noticed it at home. My home network has both 2.4 and 5GHz using same SSID. I set my phone to use 2.4GHz rather than the deault setting "AUTO", now it seems to work. Shouldn't have to do that though, but maybe my home network isn't setup correctly. This is not device specific though, it happened on my old M8 and now on s6 edge. So it must be on my end.

Unfortunately I have already tried those options, what I am looking for now is the ability to manually select what wifi band 2.4 or 5GHz my phone uses automatically on the phone itself as Apollo stated he was able to do somehow.

I can only imagine he meant router settings because the S6 doesn't show that ability. Sounds like you have to get different SSIDs for your 2.4 and 5 bands.

Sorry guys, I was wrong. I upgraded from M8 to M9 last week. I had to change bands on M9, like on the M8. Didn't like the M9 so swapped out for s6 edge. I did not have to do this on s6 edge!
I had a brain fart..sorry for confusion, it was the M9.
This is what I have found out in my thorough testing on this. The S6 / S6 Edge have issues connecting to AC Wireless networks. Upon connecting the devices wireless connection to and AC Wireless access point or router it will become unstable and disconnect randomly and in my firsthand experience will not re-establish wireless connections at all until WiFi has been manually toggled off and then back on at which point the process I described above will begin again if connecting to any AC Wireless device.
A workaround for the moment for home personal routers is to separate the SSID's if they aren't already for both 2.4GHz and 5GHz and to use the 2.4GHz channel. This won't help however for all the places you cannot change that have AC wireless AP's installed etc. I am continuing to test this device for a while before I return it as I require functional wireless in my day to day job.
This is a huge issue, I contacted Samsung support yesterday about this (You should too) as I have confirmed that this is happening cross platform and carrier, S6 & S6 Edge, Verizon & Sprint that I am aware of so I'm guessing it all of them.
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.
Hi all,
I have had to hard code my 5ghz WiFi router channel to get my Chinese tablet and ROM (zui13) to connect. This is mentioned on other threads.
I noticed that with the 5ghz channel out of range, the tablet would also not connect to the 2.4Ghz channel with the same ssid.
I was wondering if anyone has found a workaround on the tablet to get the full channel range working. I don't want to risk changing region and breaking widevine or anything else, neither do I really want to hard code the 5ghz channel - the lower range are unavailable and are the best choice for my environment as no other use nearby from neighbours.
Any ideas?
Would love to know this too. They really do not want us ROW people buying up great value hardware without some teething pains do they!
Can yours detect Wi-Fi in your neighborhood?
If so, try different channel on your router or AP to see. You can unhide your SSID to see does it connect
As far as I know without access to the kernal source we cant change the available wifi channels to the chinese rom even with root.
So without the region cuange i rhink yall out of luck.
That is weird. I have no issue with both 5ghz and 2.4ghz. I can connect to both without issues.
The wife's p7p arrived yesterday. I set it up for her, but I couldn't get it to connect to any of my home networks. The phone tries connecting and then says "Ip configuration failure" under the network name in the network settings. I had to get it setup by hotspotting it to my work iPhone. It connected to that hotspot just fine. I've had other devices like a work laptop not want to connect to my home wifi at times either, so I'm led to believe there is a network issue that different devices don't like at times. The issue comes and goes without any intervention. One day a device won't connect, the next day it will, and I don't have the issue for months.
The 2.4GHz and 5GHz networks all use WPA2 personal security settings. I just changed the 2.4GHz channel to "auto" and the channel width to 20MHz. The 5GHz networks are set to auto with an auto channel width. She left with her phone, so I'll have to see if changing the channel widths mattered, but I'm guessing it still won't connect. I don't know what is wrong or why I'm getting the IP configuration failure error on the p7p. Have you guys seen this with a p7p or other android? What was the remedy? The internet lists all the basic, obvious stuff like reset the router and restart the phone. Not sure what else to do. Will setting a static IP matter?
It's hard to say exactly what could be the issue. But since you mentioned that other devices have had a hard time connecting to your WIFI tells me it's not the phone but something wrong with your router.
Make sure your wireless router(s) have the latest firmware update. Whether your routers need a firmware update or not DO A BACKUP of all the routers settings and do a factory reset of the router...after the reset restore the backed up settings, otherwise you will have to redo all the router settings.
Do a "network" reset on the phone and try to reconnect to the WIFI router after all the router updates/config are finished. Unless you really need it turn OFF 2.4 GHz. Only "older" WIFI items use 2.4. Make sure DHCP is turned on in the router. You can use a static IP but that shouldn't be necessary.
Also, make sure you have an adequate number of free IP's available for dynamic distribution. Check all your DHCP settings on the router. There's no need to reserve, or keep IP's for certain devices UNLESS you are doing something unusual with a device.

Well it depends on how much "range" you need? Your P7P uses 5 GHz.
5GHz should be able to extend everywhere in your house unless you live in a concrete bunker or a palatial estate. 2.4 will penetrate better and farther but you may not have anything that even uses 2.4...so turn it off. Do you need to go out into your (corn field, or the back forty) to receive WIFI? If not, then turn off 2.4
Also, make sure you have an adequate number of free IP's available for dynamic distribution. Check all your DHCP settings on the router. There's no need to reserve, or keep IP's for certain devices UNLESS you are doing something unusual with a device.
Not sure if changing the bands to 20MHz and auto for 2.4GHZ and 5GHz respectively did it or if something "just clicked" but the p7p connects to both now.
