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.

My wifi is very spotty at best. It always seems to say it connects just fine but it won't let me actually use it. I just went and stood right above my router and had full wifi strength and couldn't browse the internet. Are there any solutions to wifi issues or do I probably just have a bad wifi chip?
There could be a ton of different reasons why you can't connect. There might be a compatibility issue (some devices just don't get along), there might be an issue with security (you aren't using WPA2/AES on your router), there might be a channel issue that can be fixed by trying another channel on the router, the list goes on and on.
What kind of troubleshooting have you done so far? What router do you have?
Running a netgear WNR3500L with WPA2 encryption. All I've done so far is a simple restart of the router.
EDIT: downloaded and used wifi analyzer to see which channels were open and they looked to all be about the same. I switched it to 6 for tests without any improvement. My router auto detects the best channel to be on. Any other advice?

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,

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.

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?

Network Mode: Mixed
Channel Width: Auto(20MHz or 40MHz)

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)

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.

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.

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.

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.
Is anyone here also experiencing the same problem with me?
I found that from time to time, my XZ Premium losses WiFi connection and can't find any hotspot until I turn on then turn off airplane mode, or just restart.
Here are the screenshots form my S7 edge (SM-G935F) and XZ Premium, they were next to each other and very close to the router.
Please help me, thank you.

Wifi was spotty before the Android 8 update but now it's almost unusable. Every now and again it will just stop showing wifi connections, toggling wifi on and off might show a connection or 2 but it will either disappear or just say "Disabled" when trying to connect to it. Reboot solves it for a little while.
Usually use 2.4Ghz wifi with a variety of router brands.

Happens here on Android 8 as well, quite annoying to be honest. Sometimes drops the connection for no reason, and then when I click on WiFi settings, it doesn't show any connections till I turn WiFi on and off and even then it'll only show 1 SSID, turning it off for a while longer and then turning it back on brings back the rest of them and then it'll connect, but it's stupid how I have to keep doing this every few hours.
I set my 2.4 and 5 GHz bands to different names and join only the 5 GHz, and I don't get drops. On Oreo rooted.
i have xperia xz premium with Oreo 8.0 I encounter the same problems when I'm connected to my wifi, suddenly the data connection is blocked, and when this happens I have to turn off and on the wifi symbol to restore the connection. I do not understand why this happens. My phone is updated to the 47.1.A.5.51 system with November google patches. My modem is Billion Bipac 7800N
So it seems to be a common issue, anyone know if Sony is aware of it?
Where can we complain? It's their damn top of the range phone and it's most basic function isn't working right.

Do a Google search for WiFi and Oreo and you will see that this is affecting multiple cell phones.
Do they all have the 835 chip in them???
I think it is an Oreo issue.
I have no such problems and I have Oreo and the 835.
Try disabling IPv6 on your router.
This is still OS/firmware issue but this temporally fix the issue

I found the solution:
My network works with two devices:
1 ZTE Router (2.4GHz)
1 D-LINK Repeater (2.4GHz)
In the router my XZ Premium works nicely, in the repeater happen exactly what you said, Connect apperars "no internet" after 1 second and wifi on Smartphone is automatically disabled or wifi stay enabled, but says "disabled" on network.
So.. I checked the wlan settings of the two devices in my network exhaustively item by item and I changed the devices settings about 20 times, I and I found that none of the settings matters (wpa or wep, 5Ghz or 2.4Ghz, Bandwidth 20Mhz or 40Mhz, type of network b / g / n, nor channel 1 to 13) just ignore this.
What REALLY MATTERS is a option in the advanced wlan settings, called "Fragment Threshold" this value was at 500, I changed it to the maximum (2346) and my XZ Premium started the connection instantly. Explaining: increasing this value defined that the packet can be up to 2346 bytes before being fragmented, so we deactivate packet fragmentation, reducing overhead and ensuring the best transmission rate possible, so this option determines the size of the frame.
Put simply: Go to advanced Wlan settings, locate "Fragment Threshold" and change to the highest possible value. That worked for me =)
worked for me
1- turn off wifi in being wifi settings ie where you view your wifi networks
2- select "scanning settings". it will show once you have turned your wifi off
3- turn off wifi and bluetooth scanning
4- go back turn wifi back on and enjoy

It did not work for me, unfortunately.
I know I am reactivating this thread after nearly 3 years of the last post but did anyone find any effective solution to the Wifi issue?
Hi there,
I have a Pixel 3 and my laptop randomly disconnects from the wifi hotspot, when I am moving through areas with high wireless congestion. I used a Redmi Note 4 with LineageOS before and did not have that problem. It only happens when I am on the train and I also see lots of messages like this in the logs of the laptop:
wlp2s0: CTRL-EVENT-SIGNAL-CHANGE above=1 signal=-38 noise=9999 txrate=650000
And especially this one:
wlp2s0: CTRL-EVENT-CHANNEL-SWITCH freq=5200 ht_enabled=1 ch_offset=-1 ch_width=80 MHz cf1=5210 cf2=0
wlp2s0: CTRL-EVENT-CHANNEL-SWITCH freq=2457 ht_enabled=1 ch_offset=0 ch_width=20 MHz cf1=2457 cf2=0
Often times, the laptop seems to be able to follow the channel changes, but sometimes it doesn't. I continuously ping the ip of the Pixel 3 (which, btw. switches, every time I activate the hotspot, within the 192.168.43 subnet, I had 192.168.43.81, 192.168.43.35, 192.168.43.60, ...). The laptop still shows it's connected, but the ping to the phone fails.
Those frequency changes even jumps bands. Initially I would be in the 5Ghz band, but the Pixel 3 would switch to the 2.4Ghz band during operation. Presumably, because the 5Ghz band is too busy. I believe the disconnects (which aren't really detected by the network manager of the laptop) are connected to the channel changes, since I usually see a message for a channel change in the logs around the time I lose connectivity.
The options in the hotspot dialogue are very limited. Thus I was able to try all combinations, except for turning off encryption.
I am currently using Android 9 Pie, since we are getting 10 Q soon, maybe it will be better.
The laptop is running Debian GNU/Linux 10, but the wifi chip is fairly old (Intel Corporation Wireless 7265) and well supported, so I don't expect that to be the issue. I am also thinking about filing a bug with network-manager for failing to detect the loss of connectivity, but since I did not have the issue with the Redmi Note, I am also looking at the Pixel 3 as a potential way to fix this issue for me.
Are there more options hidden or other accessible, such as turning off the channel switches
I am now running Android 10 and still have the same issue, unfortunately. I also presented this issue over at the Google support forums:

So far, no solution.
