Android 7.0 Wifi dropouts

Recommended Posts

I have an Android tablet - nVidia Shield K1 running Nougat 7.0 (yes, nVidia can't be bothered giving me 7.1.1).

It pretty much sits around nothing all day at home.

 

When I was running Marshmellow 6.0, the wifi would dropout once a week and required a full reboot to get it working again.

So it seems it's an issue in Android, but with 7.0 I have a reboot once every few days.

 

Anyone got any ideas (no I don't want to install LinearOS at the moment)

 

PS my router is this one

Check router settings, make sure there's not a lease time that might inadvertantly kick clients off.

 

Other than that, the obvious is to do searches as if it's a known issue there'd be plenty complaining about it.

There's usually multiple ways to toggle wifi (like power-bar widgets etc) though I suspect it won't help.

 

Probably some nice bug in the OS. Seems par for the course with Android that whenever they update it, something gets broken.


Maybe relevant, maybe not. Apparently the wifi antenna location was poorly thought out https://forum.xda-developers.com/shield-tablet/general/shield-tablet-k1-successful-wifi-signal-t3724565

 

But really, anything wrong with a popular device should be known on XDA https://forum.xda-developers.com/shield-tablet

I'm in the room next door the router so the crap antennae isn't an issue, it's always above 3 bars.

And it completely drops out too, it will not reconnect whatever I do - it will not see the that wifi router at all.

I suspect the power saving feature shuts down the wifi by accident.

Funny, I am running 7.1.1 and have run 7 to 7.1 and I have never experienced the dropouts that you mention. However, in my experience, I have seen separate Android devices (different brands and different devices) work completely differently. So, my opinion is that is, at least in this situation, that how the devices deal with wifi or connections, is a function of the manufacture's design paradigm rather than an error or flaw on the part of the AndriodOS. I could be wrong though.

True but with Android 6 it took a week - Android 7 takes a few days. Didn't have a major issue with Android 5 oddly.

I suppose these are official updates and not dodgy user created flashes?

 

Don't you turn off wifi when you put the thing in standby? I do, generally if you leave such things turned on it'll use way more power.

I leave it running with wifi enabled and charge it up once in a while

Mainly because I get six hundred zillion app updates!

 

I used to turn it off but then I get hit with wall of app update notifications when I started the tablet.

you're looking for this guy:

 

Use legacy DHCP client:

this function allows to use the DHCP client from Lollipop instead of the new Android DHCP client.

Nope that option got nerfed in 7.0 too.

I won't get Android O BTW so the cyanogen/LinearageOS route is only one left

Why would that help? I thought the problem was supposed to be at the tablet's end.

 

Well maybe a better router with smarter DHCP might help. Saying that, it works pretty good with everything else in the house including my Android 7 TV device.

Sorry to ask the obvious, but why not just roll back to the Marshmallow Official from?

Well yes, if I could download that from nVidia but I've never found that unless you know where to get it.

Android M was pretty nice.

 

OK I found it

BUT the Marshmellow release doesn't have the KRACK patch like Nougat one does, I guess I'm stuck.

Are you likely to have people in your area who know how to exploit KRACK?

I'm in a residential area, so I only have about 6 houses in range of my wifi. And its a dead end so i'd spot a wardriver.

 

And even then, once they're on, my INTERNAL network is also secured. (file shares have passwords, router has a password, etc).

And I use a VPN for web browsing.

 

So besides using my bandwidth, I'm not too scared of people being on.

Pretty quiet around my place and my wifi isn't that strong once you leave the house. I guess I should be OK.

Saying that, reinstalling all my apps ...
