Hi everybody,
I'm developing web site for mobile and I've faced an issue on our server. When I want to upload a picture and when I'm connected to the GPRS mode I experienced a random failure. Sometimes the image is received and sometimes not.
I'm using Opera 9.51b2, with IE everything is fine and I can upload. Other crazy difference is when I'm using a wifi connection I don't have this problem (or maybe once or two when I had a crap signal)
I did some tcpdump on the server and apparently the upload is ended after about 17ko (why?). Opera sends a FIN ACK around this amount of data.
Here an example of the exchange:
POST an image
chunk
chunk
chunk
around ACK 17000 Client send a ACK FIN
Server continue to send data and send a success page
I've tried on other website as well like imageshack.us pikipimp.com and I've the same result.
I've also tried with different phone models and operators and I think this issue is more frequent with old phone.
If this issue is related with a bad connection and/or with old phone, why is it such a difference between opera and ie ?
Thank you
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.

I have T-R42 V2.0 device and I have slow download speed over Wifi.
At start up WiFi download speed is about 7MBps, but after 1-2 minutes latter download speed drops to 0,5-06MBps and stays at his speed or lower. Upload speed is OK!!!
I have:
- excellent WiFi signal
- Wasser 1.2.5 Rom and 1080Kernel (same problem was on original ROM)
- Linksys router
- 15MB/15MB home connection
- tried to connect device on few different routers and connections and I get same result - slow DL speed
- more people have this problem.
One guy solved this problem on V1.0 device with "bin" - I'm not exactly sure what this means! Maybe driver modification????
Can you please help me solve my problem because at this point my device is useless.

Hi, when I download something with my PC/Nexus 5 I usually get download speeds of about 11mbits, but when I try to download files from the Play Store/the Browser on my OPO I have download speeds of ~2mbits... If I download for example 4 files at the same time with the browser it goes to 8mbit... It cant be the fault of the download server, because it gives me full download speed on my other devices...
Anyone who has encountered the same problems/who knows a fix?
Thanks, Tom.
same... Speed test on my one is just slow... I just got it today compared to other wifi or just data transfer seems slow
Change the TCP Congestion Algorithm on your phone, search on how to do it. My wifi speeds are perfectly fine, getting 80Mb/s+ on my wireless n router.
thought it was just me...
I had the same issue. You have to go to settings, WiFi and then click on advanced WiFi and uncheck WiFi Optimization.
Turned WiFi optimization off and back in business.
Now to figure out proper network settings. I find the phone not on 4g when it should be

Hi, I know the thread is old but my download speeds are slow with my OPO. And just with my OPO. (Iphone, Ipad, Former HTC One M8 works fine)
I realised it with the Facebook App and in the Google Play Store.
When I open the Store and go e.g. to games section, it shows me the games apps but not their pictures. If I turn off WiFi it works well.
Same in Facebook, I can read the comments but can't see the pictures. Again, turning off WiFi and using my mobile connection works fine.
I turned off the optimization, but it didn't help.
It increased the download speed (Speedtest App from Ookla) to 25 Mbits (from 12 with optimization) but the surfing problem remained the same..no pictures in Google Play Store e.g.
Im getting 40 Mbits with my Ipad 3 (without losing any) and 60 mbits with my Notebook.
I restartet the phone (shut down, wait 10 sec, turn on), turn off and on the wifi optimization, checked my WiFi-Channel with "WiFi Analyzer".
When i turned on the flightmode and then turned on only WifI, I got 55 Mbit download! My connection worked fine for a few minutes and went back to 12 Mbit (with optimization) and 25 Mbit (without optimization)
How can I fix this issue? Surfin with WiFi at home is not possible like that, even when I'm getting 25 Mbit as downloadspeed, which would be more then fine to surf on the phone..
Edit:
Im running the newest: 11.0-XNPH38R
Hey folks!
It's worth checking, take a look into Settings -> Performance -> per-app profiles. Make sure it's unticked.
With that option enabled I had maximum download/upload speed up to 5Mbps and it was driving me crazy, I was thinking of selling 1+. Anyway, disabling per-app profiles saved the day and download speed was as on N5.
Hope it helps.

Hey Guys.
I got my pixel yesterday and it was already running the latest Android 11. I installed the October patch too.
The issue I am facing is, the wifi download speeds are poor.
For example speeds I see on speedtest dot net app :
On a 2.4ghz network
Download : ~20Mbps
Upload : ~60Mbps
On a 5ghz network
Download : ~25Mbps
Upload : ~100Mbps
I can confirm this is not an issue with my wifi because no other phones at home ( iphone SE and a samsung S10) face this issue. I get download speeds of 70 and 180Mbps on a 2.4ghz and 5ghz respectively
Rebooted router.
Rebooted pixel.
Restored pixel to factory defaults.
Tried with/without phone case.
I still have poor download speeds on pixel 4a.
Any suggestions or if anyone else facing the same issue?
The issue was with speedtest app. Downloaded other apps that show speeds correctly.

i typed speedtest dot net app into google and got the ookla one. i waded past pages of requests for location sharing and the like and eventually found the speed test page. I got 43.1/19.7 down/up on 2.4ghz, and 45.9/19.8 for 5ghz. no idea how you're getting such a fast upload speed! i guess that depends on your internet connection though. i'm on infinity 2 fibre in the uk which is 67Mbps max (up/down) if i remember correctly.

Interesting. Which app are you happy with? I'd like to try that to compare!
Yes, the speed wasn't reporting correctly on ookla's speed test app.
I tried another app called speedtest master lite.
This shows me same speeds as other devices.
I'm glad it was an issue with the app itself.
I use a 200Mbps fiber broadband.

Well....I'm glad you're happy but that app gives me repeated 15mbps download times; a third of what I'm seeing with the other app. And no way of choosing which server to use. I'm never sure how much to trust these apps. The only proper test would be to download something from a fast server; well seeded torrent site etc.
My choice is fast.com (Netflix property). Click through for additional details after the initial read. Useful and widely available.
This assumes you are using a reputable browser that itself is not a bottleneck or otherwise compromised.
I eschew speed test apps (including Ookla variants as most are advertising cesspools. Why mess with another app. ugh.
I'm not having speed issues.
No problems here . . please check the screen shot.
