WiFi connectivity issues

Just received my Nexus 5 today and I'm noticing some strange connectivity issues while on WiFi. Some apps would complain network is unavailable, Facebook would load with no pictures, etc. This happens randomly, sometimes after few minutes others - an hour(s). Rebooting the phone or even cycling WiFi off/on usually recovers it, until it happens again. Cellular data works fine all the time. It can't be the WiFi network I'm connecting to as I have a myriad of devices that have worked and continue working without any problems.
I tried 3 other WiFi networks (different routers) with different configurations of encryption as well no encryption, switching between 5GHz, 2.4GHz, no matter what, problem occurs sooner or later.
Noticed on Google support forums few users describing exactly the same issue, surprised I didn't find reports here on XDA. Maybe not many people got their phones yet.
Anyone else getting the same "treatment" from their new Nexus 5?

I am seeing exactly the same thing. Wifi will work great, then all of a sudden, nothing. Stays that way for a couple of minutes, then all of a sudden it works again.

How many bars does the sifi icon show ?

Number of bars doesn't matter. I can have full bars sitting a meter from the router and issue would happen anyways.
I tried playing with WiFi optimizations in advanced settings to no avail unfortunately. Hopefully this is a bug that Google can quickly fix with a software update

Same here. Got my N5 yesterday and experienced the same at home. Same for my brother.
Hope that gets clarified soon. Not the nicest feeling having a new phone with that (or any) kind of issue...

Yes, my N5 started doing the same on my home wifi connections (using Apple's Airport Extreme 2.4/5GHz router).
The Playstore or Youtube apps would not display images or take forever. When I switched wifi off those apps worked fine.
I got it working again when I "forgot" my wifi setting for the 2.4 and 5Ghz channels then reconnected to the 2.4. I'll let that run for a day or so then try activating the 5Ghz.

Hmmm... This may have been what was going on here...

Is it similar to the issue I described?

I usually don't have connection issues outright, but do have issues reconnecting. However I did notice I list connection overnight after I went to bed.

Nah. Its no connection issue. We can connect easily and have full signal bars, but still no connection randomly for a couple of minutes.

Hmm - no I don't think that's the one. Phone connects fine, just over time randomly does this thing with the connectivity issues.

--EDIT
OOPs my mistake...
I looked in Setting/Wifi/Advanced ...
I turned OFF "Avoid Poor Connections"
and everything seems to work the way i want ( when i tell it to go to Wifi, it does that )
--EDIT end
i added star to this issue because of same problem . If enough stars get added Google may get on it.

(Didn't know if I should create a new thread for this as it is a wifi issue but seems to be soemthing different than what the OP decribed, my issues are related only to playstore app downloading)
I too am having terrible wifi issues on my new Nexus 5. But mine are different from those described here I think. Whenever I cycle through the wifi, turn it off and on again it doesn't fix the problem (not temporarily and ofc not permanently)
When browsing the web, the play store and mostly everything it works great and is very fast, BUT when downloading or updating an app the wifi speed is practically non-existant.
Sometimes showing that it will take 25 hours to download a 25mb app :S
This while my Galaxy Nexus on the same wifi network is as speedy as ever.
I have tried factory resetting my Nexus 5, I have cleared the cache and data of the play services app and of the play store app, I have tried changing the wifi bands (from auto, to 5 to 2.4 and back to auto), I have turned off the wifi optimization, but none of those things helped. I even tried some DNS HSPC wifi settings thingy I read here
That didn;t help either.
I have unplugged my router and replugged it in but that didn't help either.
I literally had to leave my brand new Nexus 5 downloading all night just so that it could install the apps I wanted on it. So far for playing around with the phone on day 1
What makes it even weirder is that occasionaly the wifi issues resolve itself and I can get good download speeds for several seconds or sometimes up to a few minutes, but then right after it is straight back to crap speeds. Some other reported that only while making a portion of the map available offline in Google Maps their app download speeds were great, but that didn't work for me either.
I don't know what to do and if it is a hardware issue or a software issue. Please help me.
Below some info that might be useful to helping me solve this.
White Nexus 5 32GB
Bought from US play store
Shipped to and using it in the Netherlands
Currently does not have a SIM card inside (that is still in my Galaxy Nexus till the wifi issues are resolved)
Unrooted, only installed the mandatory update during the setup
All apps downloaded are apps that are also on my Galaxy Nexus which works without a hitch
Any and all suggestions/ideas/help are welcome

I think the problem somehow related to DNS. I found that if I configure static IP settings and point DNS to Google's instead router's, things work normally. I reconfigured my router to advertise 8.8.8.8 and 8.8.4.4 as DNS servers for the DHCP and now for over 24 hours I haven't experienced the disconnection issue.
If your router cannot be reconfigured, try assigning static IP settings and Google's DNS to see if it helps.
I still believe that's a software bug on the phone, we can't blame a device (the router) that has worked for years and works fine with everything else but the Nexus 5, being at fault.

I currently can't reconnect to my Wi-Fi at home as it's stuck showing the last scan I did some 40 miles away at a shopping centre earlier today.
Of course none of these networks are now present, yet all mine are shown as not found!
Guessing a reboot will fix it as toggling Wi-Fi didn't. Mobile data is working fine.

Not as tech as I want to be, so could you explain to me what the difference is in setting the DNS to Google's instead of routers? I have no idea what DNS is/does so what happens when you point it soemwhere else?

DNS stands for Domain Name Service. What it basically does is to translate those easy to remember names such as www.Google.com to the actual numeric address (also called IP address) of the server that serves that site on the Internet. Home routers almost always sport built-in DNS service to speed up name translation requests from internal devices. What I figured is going on on the nexus 5 is it "doesn't seem to like" some DNS servers. Works fine with some, doesn't with others. What happens is at one point, for whatever reason, it stops being able to translate names to addresses and as result "decides" there is no working connection as it fails to connect to the corresponding servers. Google hosts publicly available DNS servers with the easy to remember IP addresses of 8.8.8.8 and 8.8.4.4 which apparently Nexus 5 doesn't have problem working with. Once it gets "instructed" to use them instead router's, everything works fine.
At least that's what I figured is going on so far.

BTW, just found one small and very useful app that can display information about WiFi connection as well as DNS servers associated to it.

Thanks, but that wouldn't fix my issue right, because it doesn't explain why only play store downloads are terribly slow while the rest works fine.
Gave it a shot and at first it seemed to work, but after a short while the problem re-arose

DNS has nothing to do with weak or lost WIFI connections...
You can be perfectly connected, at full n speed to a WIFI AP without getting proper acces to Internet : THIS can DNS isue.
But in no way a DNS isue can leads to lost or very weak WIFI signal.
2 solutions are possible with Nexus 5 :
- WIFI module has the same badly coded shape as camera one...
- its hardware related wich, no need to say, could be the worst case...

I am having the same issue since day one. In fact it just occurred as I was replying to this thread. Mostly occurs when the phone comes out of sleep mode. However it will occur often and at random.

Chrome Adware: Links and Pop-Ups

Hello Folks,
don't know where else to find help and - strangely - found nothing on all the interwebs.
My GFs Chrome (latest build) all of a sudden shows hyperlinks in texts and pop-ups that are clearly adware related.
Strange thing is: it happens cross platform (Chrome on Mac and on Vanilla Android 6.0.1) AND cross connections (home WiFi as well as over data connection).
Wiping Chromes data/cash solves the problem for a short period, but problems appear again. Really don't know what to do or where to begin with.
Malwarebytes and Kaspersky for Android find nothing, I also don't think the router could be the problem, because it happens as said across connection types and there are no problems on my OPX, N7 or Windows Laptop. Any ideas or suggestions? Help much appreciated.

some apps fail to make internet connection via a specific network

The Problem:
"My device" encounters this problem while it's connected to "my home WiFi". Some apps fail to make internet connection, and this problem wasn't there before I upgraded from lollipop to marshmallow (officially). The strange thing is that other devices do not experience the same problem when they're connected to the same WiFi. Also, If I switch to another network, all apps work fine! So it only happens with one device relating to one network.
Things I tried:
I tried resetting the router (HUAWEI EchoLife 626 CPE), factory reset to my phone (Galaxy J5), reconfigure time and date, messing with dns... no luck ...
Other details:
Google Play Store and Google Drive are not connecting. Facebook hardly connects and Gmail doesn't send attachments, Messenger doesn't send photos and links! Youtube works great.

Please, if someone has any idea about that, I cant find help any elsewhere!

Judging by what you've posted, the device works fine on other networks, this suggests to me that the issue is in your network and not your device.
This forum isn't the kind of place to help you with network issues. This forum deals with the devices themselves.
Your problem does not seem to be the device.

But also as I mentioned that other devices do not face this problem when they're connected to the same wifi. That's why I thought it's related to my device.
Also, some network community directed me to here after reading my problem!
I know it's not appropriate to ask for help in PM and I don't do that.

Strange Connectivity issue

Well, another strange issue with my brand new MM3.
Global rom there.
I noticed that two (and only two) apps ("Ip cam viewer" and "Vera Mobile") are perfectly working when connected to WiFi but as soon as I switch to LTE, they stop working.
The apps are launching, but says that there is a connectivity issue. Of course, I checked the regarding parameters (i.e. ip public adress, port, password...) on booth apps but as those paramaters perfectly works with another phone, I really don't understand what's this issue.
No problem with youtube, or gmail, or any other app...
Anyone can help ?
Thanks

Am I the only one facing this issue ?

This is probably to do with your Vera app settings. I don't use the Vera Mobile app, I'm still using Home Buddy, but the app communicates through the external MIOS servers unless you're in local mode (on your home wifi). Also, check the IP address of your Vera (you really need to make it static, or reserved on the router), otherwise you'll have difficulties in local mode if the IP address ever changes.
The other thing you can try is logging into MIOS through a browser session and check that it works, if not then you know you have an issue between the MIOS servers and Vera.

Thanks for your reply !
It works while logging through browser.
My vera's ip is fixed.
Furthermore, my ipcameras also have fixed ip adress, and the problem is the same with the "ipcamviewer app".
Every other apps are perfectly 4G working so... WTF ?

As I said, it's nothing to do with 4G or the Mix 3, it's because the MIOS server is unable to reach your Vera through a remote connection. I can't log in to Vera Mobile to take a look because I don't have the login credentials for the account I created when I tried to "upgrade" to a Vera Plus, but to resolve the problem you're probably going to need to talk to MiCasa Verde support. If you want to prove it, try connecting to a wifi network other than your home network and see if you get the same problem as when on 4G.

Maybe I'm not correctly explaining my problem.
First, I've got a Veraplus.
Regarding Vera Mobile app :
- local wifi : no problem
- other wifi network : no problem
- 4G with web brower : no problem
- 4G with VeraMobile app : issue
--> so I think it means that the MIOS server is able to reach my VeraPlus through a remote connection, right ?
Second :
Ipcamviewer app
Local Wifi : no problem
Other Wifi network : no problem
4G : issue
So I really really think that the problem comes from the MM3, especially since I previously owned a Mi Mix and there was no issue at all with both apps Ipcamviewer and VeraMobile...
All my apps were restored from my google account, so is it possible that the problem comes from a "cache" I should delete (restoring apps include ip adress, port, login and password).
If so, how to "clean the cache" ?

You can clear the cache on the apps by long pressing (not sure if this works on MIUI) and clicking info, then clearing storage. Alternatively, find the app list in Settings and do the same thing that way. This isn't going to be a MM3 problem. I have the same issue occasionally with Home Buddy and it's always a MIOS server issue. The connection to the MIOS server is actually the other way round, it's an outbound connection from the VeraPlus to MIOS, so you may also want to check that the Vera unit can get out. I couldn't live with UI7 on the Plus, so it's still sitting in the box and I stayed with the Vera 2.

Ok.
Let's suppose that there were a problem with the MIOS server.
BUT :
That does not explain why there would be a connectivity problem with the IpCamViewer app...

There have been tons of IP cam related problems for months, on all devices. I use YiCams and it works perfect on iOS. But on our MM3 and also Note 8, they don't work right at all. I see the same issues with all the major IP cam services. Xiaomi told me it has been some sort of persistent server problem, but why its taken 2 months so far to fix, I don't know.
My "best" guess is maybe they are all using the same push provider and/or 3rd party framework, and it has **** the bed (they all seemed to upgrade their apps around the same time, too, and they all look suspiciously similar)

Very strange answer from Xiaomi considering the fact that I never had this issues with my previous Mi Mix... Which is still perfectly working in 4G with both IpCam and Vera Mobile apps...

Still unsolved.
Am I really the only one facing this issue ?

What does that tell you?

More than words, this is what happen with wifi (first pic) and with 4G (second pic)

Question Selective inability to connect

I have a new Pixel tablet as of yesterday. So far it seems kind of buggy. The biggest problem seems to be with connecting to only some websites. It is definitely connected to the network and can get to some websites. I had this problem yesterday and solved it by dropping the cache for some of the Google apps. It is not working today. Today I find that links from Google search results all return "This site can't be reached". I can get to the sites outside the Gooele search. Only a problem on the pixel tablet. Works fine on other devices in the house.

Did you try a factory reset? Sounds like a software issue. Did you try connecting to a hotspot instead of house wifi?

Not sure on this one. I think you can specify in the Google app to use the Chrome browser for web searches
