[SOLVED] Any idea what is wrong with my WiFi?

Hey all,
I just received my Nexus 7. I'm having trouble with getting connected. I can connect to the router fine, and the WiFi indicator turns blue, but I can't access the internet or occasionally will be able to load a tiny bit of data and then it stops.
I've been able to get a little better access by choosing a static IP instead of DHCP, but it's still "choppy." For instance using the Speedtest.net app I'll get a burst of data, then it flat lines. Burst, nothing, burst, nothing, etc. Chrome will sometimes load a page and sometimes it will time out. GMail has been syncing very slowly, every once in a while populating some more conversations.
I've tried my GNex at the same time and have no issues, as well as on my PC, so it's not an issue with my ISP.
Any ideas what I can check? I hope I didn't get a defective unit. I ordered from newegg and I don't know how they work with returns and exchanges.
Thanks in advance for any insight.

How close to the router is your nexus?

Fairly close. I show 2 "bars" of connection and in the WiFi panel in the settings it says the connection strength is "good."

Try moving right next to the router and let us know if the problem persists.

Issue persisted even when a few feet away from the router. However, performing a factory reset on the Nexus and power cycling the router seems to have remedied all the issues. I can connect via DHCP, browse the web just fine, and am able to get consistent data on speedtest.net at 20+Mbps.
Everything is working great now, this thing is awesome!

Glad to hear it!

[Q] Facebook app cannot connect via mobile network on Nexus 4

My Facebook app (including Messenger) cannot connect to Facebook over my wireless network. This has been happening for weeks now. All of my other apps, including the browser, can connect to the internet over my wireless network with no problems (I can even access the Facebook mobile website via the web browser). The Facebook app will only work over WiFi. When on my wireless network, it just shows "updating" for a long time, until eventually displaying a "network error" message.
There have been a few times in the past couple weeks, however, where the app will connect and update over the wireless network. Unfortunately, this only lasts a few hours or so, and then it resumes not working again. Perhaps this means I'm having account issues.
I have tried clearing the app data/cache, uninstalling and re-installing the app, restarting my phone, etc. to no avail. I am using stock Android on a Nexus 4.
Anyone else having this problem? I've searched the web for this problem, and information seems to be scarce.

Someone started this same thread already. Its got something to do with the newest update. Use friendcaster for the time being is my only suggestion.

Happening to me too but friendcaster doesn't work either. I am forced to download a dns changer and set them to opendns and then it mysteriously works fine. Native app and all. Started with the LTE rollout here in San Diego

Yeah, Friendcaster didn't work for me either.

I think I figured it out... The Facebook app has problems when WiFi is on when there is not a WiFi connection. If you turn off WiFi it seems to work on the wireless network.

Actually, that didn't work. Oh well. Back to using the mobile website.

Edit your APN settings to use IPv4 only and not IPv4/IPv6. See if that makes a difference.

Thanks for the suggestion, by my APN is already set to only use IPv4. However, the app has suddenly started working again, which makes me think this whole problem is server side. Hope it lasts. Crossing my fingers.

How To Fix WiFi Connection Drops and Google Play Store Errors

Ever since I got my Nexus 6, it's been having problems downloading apps from Play Store and other issues. At first I thought this was a Play Store related error later realized that it was my Router that was giving the problems.
Every other article on the web tells you to Clear your Play Store and Play Services cache to fix problems, I know you all have tried those thousands of times and are still looking for a working solution.
Well what worked for me was to disable QoS (Quality of Service) option on the Router.
This fixed all the issues related to WiFi and has in turn fixed Play Store errors Error 927 etc.
Do give it a try.
Thanks.

Were do I find that on the router ? I'm clueless

Am not sure which router you may be using, because its different for each router. Just Google this: "disable qos on router name".

Its usually under advanced settings. Yes it really depends on the router. I have the nighthawk by netgear and that's where my settings are

WiFi Issues

Hello all,
I just recently upgraded from a GS6 Edge + using JoD, and admit I'm loving this phone. However, I'm experiencing a weird issue that (I believe) relates to my home network.
Here is what happens: I successfully connect to my network and all seems well. I have Internet with full bars. I can browse and watch videos with no issues. But when I go to the Play store, I cannot download any apps. They just say “downloading” and never actually initiate the download.
My temporary workaround that I've found to work is to disconnect and reconnect to my network, and I'm able to get 1 or 2 downloads before I experience the issue again.
If anyone has any ideas on a permanent solution, please let me know. Or if you need more information to help.
Thanks in advance!

I've experienced the same issue you're having on my office Wifi. The strange thing is when I connect to the office guest network, all is well. I'm also not able to download any photos from Google Photos so not sure if it's a google DNS thing or what. No issues on my home Wifi either.

Ok, I'm glad to hear I'm not alone (despite issue being bad). I think it might be a Google thing, because I've also found that I can't setup Google accounts on the WiFi because it just hangs on the log in and never actually logs in. I can switch to data and all is well.
I've also been on a different network that worked with no issues, similar to your case with the guest network. Seems to be something with a very specific type of network...

There's definitely some WiFi issues with the phone. I use WiFi Calling at the office and if I get out of range from the router in my office, it will not reconnect until I turn the screen on and unlock the phone.

Same here wifi is fine except with downloading from play store

I've had some WiFi issues as well. Sometimes, I'll have a full WiFi signal yet I lose all connection on my phone. I know my WiFi still works because I can access it from the computer or a Tablet. The only way to get the WiFi on the GS7 working again is by turning it off and back on.

I've noticed this too, but it seems to kill all internet and i have to cycle it..also I've noticed WiFi off several times

Ok guys, I'm hoping it's just a software issue with Samsung's Marshmallow that will be fixed soon. It's a shame considering the phone is so great in other aspects.

I think I fixed the issue by using google dns, but I actually did more than that. I reconfigured my home network to use on asus router instead of the old motorola from att which cannot set dns and handle heavy traffic

I'm glad that worked for you. On my end, setting the DNS to standard Google 8.8.8.8 and 8.8.8.4 don't fix the issue. I don't think my router is to blame as it's a fairly new Linksys and all the settings seem to be set up properly as I've never had the issue before this phone. I might need to tinker more though.

I've got an older Linksys N dual band at the office, upgraded to run DDWRT, and a Netgear AC router at home. I can reproduce the issue both places, so I'm confident it's an issue with software that T-Mobile/Samsung need to address.

Ok, well then I guess we should all try contacting T-mobile and letting them know about WiFi issues. I don't want to have this phone ruined by poor net code or whatever it is.

Though it was fixed, I still think it's something wrong with the software because I have several android devices (including both 5 and 6 android), but only two S7 edge have this issue.

I finally fixed the issue for me by setting the DNS of my router itself to Googles Public DNS addresses. Previously I thought changing it on the phone in network settings would do that, but apparently not! Now my phone is working great on my network.
Still an issue that needs to be addressed because some networks we don't have access to change anything.

I've been going back and forth with T-Mobile and Samsung on Twitter regarding my issues. Samsung wanted me to take my phone to Best Buy, where there is a Samsung Experience kiosk, and have it reloaded with factory firmware. I told them I already downloaded it from SamMobile and would just flash it myself in ODIN. Did that last night after backing my stuff up to the computer, and not a single difference has been made.
My WiFi is rock solid, as long as I don't walk out of range from the router. If I do, it will not reconnect until I turn the screen on. No need to unlock it, just need to turn it on.
Also have a ticket in with T-Mobile for the poor radio performance compared to the Note5. We'll see where that goes.

Yes it does. However my office is not in a Band 12 area and the signal is fluctuates between Edge and very weak H+. As soon as I get away from my section of the building however, full LTE and no need for WiFi.

I think this is the same problem I was having. Here's a link to my solution.

Although that may very well make it work, this is still something that Samsung and/or Google need to address as not every router's settings are accessible to everyone especially at work or public hotspots.

I know this won't help many (or anyone 'cuz lock bootloader ), but I think I might've disabled IPv6 on my previous phones, but you need root for that.

Mobile Data Only App

The other day I came across a new option in the connections settings menu called "Mobile Data Only Apps". And it says the apps you select will ALWAYS use Mobile Data, even when connected to WiFi.
This is something that has never existed in android before and is an absolute godsend because I have been trying to get something like this to work on my phone's over the years, with no good solution. My work WiFi restricts VOIP calls so apps features like WhatsApp and signal calls do not function while I am at work.
The only problem for me is that it does not seem to work as I am still unable to get these VOIP calls to function consistently when I am at work. I have enabled mobile data always on in developer mode, but the VoIP calls still don't work. Has anyone else had success with this.

Interesting, will try to set some apps to see how it works...
Sent from my SM-G975F using Tapatalk

It actually now works consistently, however, it requires both wifi and data connections to be rock solid. When I'm on LTE and the Wifi is strong, I am able to receive WhatsApp and signal calls without issue (work WiFi restricts access to both VoIP calls). However when the connection drops from LTE, the dual connection doesn't work so well.
Good job Samsung.

Only if you can find a way to restrict certain services on your router. If you know the ports used by certain apps like VoIP, you could block those on your wifi router and then have the apps use mobile data only.
I am really excited about this since Android never allowed simultaneous network connectivity in the past. I don't know if this is a Samsung only feature but it's great.

Aww shoot. I'm not going to mess with the router. Wife uses it for work. Thanks for the explanation .

LimeyBastard,
I just figured out a much better way of testing the feature without touching your router.
1. While connected to your home WiFi, Open up a browser app (I prefer Firefox focus since it's in incognito mode by default), go to one of those IP address checking sites like whatismyip.com and take note of the IP address.
2. After this go to settings and allow the browser app to access mobile data only.
3. Without disconnecting from the wifi network, close the browser app and reopen it and then check your IP address. It should be different from the initial IP you got under WiFi (it should show you the IP of your cell network provider.)
I checked my wife's Note 8 and this feature isn't present, so it appears it's an S10 only feature for now, but I could be wrong.

I have attached mine as well. Is your cellular data ISP different from your home internet provider? Also did you refresh the browser (I force stop it and then reopen before checking the IP). Also ensure the browser is one of the apps listed as using mobile data on the persistent notification.

Yes, my cell service T Mobile and my home wifi is charter comms.
Edit . So I just reinstalled firefox then before launching it I changed the setting for it to use mobile data only. And it seems to work. Weird.
