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?
I have an ASUS wireless router, and my wi-fi connection at home is dropping all the time (especially while playing Hearthstone, frustratingly). Is anyone else experiencing this and/or know how to fix it?
My experience has been that the wifi on my phone works great, leading me to wonder about either your router or your environment.
questions and things to try
1. Does you phone work well with other access points? i.e. is the problem only at home but it works elsewhere?
2. is your home a "noisy" wifi environment? i.e. lots of other nearby access points or other devices in the 2.4 Ghz band?
a. Get an app from the play store called Wifi analyzer (its free). You can see a chart with all the access points your phone can see and what chanel they are using. It can show both the 2.4 and 5 Ghz bands.
b. If your router is showing up on the same channel or a nearby channel as one or more other access points, try manually setting the channel on your router to something else that no one else is using or near.
c. If you router is dual band (i.e. has both 2.4 and 5 ghz) and you are using 2.4 Ghz, try using 5 Ghz. You can set your 2.4 and 5.0 Ghz to different SSID's (network names) so that you can easily tell which one you are connected to.
3. Do other wireless devices you have also have connectivity problems? Consider a new router?
I had problems with wifi dropping. I went to Comcast and swapped out my modem for a new modem/router and haven't had the problem since

I've had very poor speeds on WiFi compared to my nexus 6p. Annoying it's so slow

I suspect the issue has to do with my Asus router. Apparently Samsung devices and Asus routers don't play well, according to what I've read, but I have no idea how to fix it.
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 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:
https://support.google.com/pixelphone/thread/14799895?hl=en
So far, no solution.
We have set up a WiFi router at our summer house and all devices bar my OnePlus 8 connects without problem to the WiFi. My phone connects to the WiFi but not the internet. Have restarted the phone and removed and added the WiFi connection but no luck. Any idea what's going on?
I had this problem with my oneplus 8, European version, where at times internet connection would drop, but wifi was still connected so the phone was in effect blocked since I use VoWiFi both voice calls and data was blocked.
The problem turned out to be between my router and the oneplus 8. I had to go into the settings of the router and disable a feature called "band steering". This setting will make the two different wifi gateways inside the router, the 2.4 ghz and the 5 ghz appear as one and the same with the same SSID name. This is supposed to simplify setting up devices with wifi but is known to cause problems sometimes.
As soon as I had separated the two and given them different names, I no longer have a problem with internet access dropping from the wifi.
I have no idea where the fault happens, I only know that I have had to disable band steering with another router I had before. I think this feature might be a bit unstable.
No idea what's happened but this morning it just worked.
