slow wifi

I think this problem in only your N5.

Other wise the speed is slow but not dropping a signal...
[Nexus 5 Q&A, Help & Troubleshooting] krustykrab:
Just to confirm the problem, there are two Nexus 4s and one nexus 5 in my household all of them suffer from the slow wifi issue ie: wifi download speed slowing from 20Mbps to about 1.5Mbps, which will resume back to 20Mbps for a very short period after turning wifi off and back on again.

After reading this thread we all turned off Mobile data and the problem has not recurred.

Another factor maybe the fact that we are on O2 and are only in a basic g reception area.

Other mobile devices in the household are able to obtain a permanent 20Mbps wifi connection with no problem.

Google really needs to sort this software bug out.
[Nexus 5 Q&A, Help & Troubleshooting] meangreenie:
Wouldn't hold breath for Google to fix this. Last year waited 9 months for Google to fix WiFi notifications on sleep state on nexus 4, eventually got half fixed with the release of 4.3...you had to turn off WiFi optimisation for it work properly

Eventually got fully fixed in 4.4 just over a year after initial release.. but then we just get the annoying slow WiFi problem instead.

Google coders are a hard nosed lot.

[Nexus 5 Q&A, Help & Troubleshooting] ericjmense:
Well I switched from T-Mobile where I got E service to at&t where I now get LTE. It has been a day and I get almost my max 50mbps Evey speed test for the last day and that has never happened before.

If u rember I previously made new Google account 2 times and did restore 3 times also tries a different Sim card from t-mobile and tried all kind of settings on and off with no fix. Only thing that seemed to work is I took out Sim card over night and my speeds stayed good.

If my speed starts having issues again I will let u know but I have a feeling its fixed with the new Sim and new network. At least fixed for me.
[Nexus 5 Q&A, Help & Troubleshooting] aburn95:
Well glad to see its not just me. I just got on here to search for this problem and its the 4th thread down. My internet isn't blazing fast by any means, but definitely quick enough using my computer or PS3. But if I use the WiFi on my phone its like I'm using 2G!

I just changed broadband providers and my problem has gone!

Hit Thanks if I Helped

[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I can understand how your broadband equip and possibly provider might have something to do with this but cell phone carrier seems like a stretch
[Nexus 5 Q&A, Help & Troubleshooting] bblzd:
It's almost definitely to do with individual routers. Mine was personally fixed by setting the phone to use 2.4ghz only on my network, but the fix will be different for different routers. Upgrading firmware has helped some people.
[Nexus 5 Q&A, Help & Troubleshooting] gvdf:
Same here, fast WiFi at the beginning and few minutes later download rate drops to 100KB/S. As bblzd said, setting bandwidth to 2.4ghz solves the problem. Thanks!

[Nexus 5 Q&A, Help & Troubleshooting] alturigo:
I was having this same issue with my Nexus 4. The cause turned out to be switching between 2g-3g. I have disabled this auto-switch (3g all the time) and WiFi is now always working at full speed.
[Nexus 5 Q&A, Help & Troubleshooting] Chad_Petree:
But I think with the nexus 5 this option you mention doesn't exist anymore , on settings it looks like you can only choose one, there's no mention of switching

[Nexus 5 Q&A, Help & Troubleshooting] alturigo:
The auto-switch doesn't exist by default on the nexus 4, I was using Intelli3g. I am not using it anymore but I can reproduce it manually:

connect to a wifi (3g mode) -> switch to 2g -> sooner or later the wifi speed will decrease.

If I keep connected in 3g the speed will never decrease. I have just tried again and happened almost instantly.
[Nexus 5 Q&A, Help & Troubleshooting] illevan11:
Here's an interesting observation:

I'm able to get my speedtest/FCC speeds up where they belong when I switch to 5GHz only (doesn't matter whether cellular data is enabled) but ALL apps that use the internet are still sluggish! Chrome (every website!), Facebook, Instagram, even the Play store.
[Nexus 5 Q&A, Help & Troubleshooting] aooga:
Mine works fine on both 2.4 and 5 GHz networks. The battery drain due to wifi is terrible, but that's for a different thread. It's as fast as my computer.
[Nexus 5 Q&A, Help & Troubleshooting] surrealjam:
Not sure if this issue is still being followed here but it looks to have been acknowledged by Google. Read the last few posts and it looks like it'll be included in the next update - maybe a 4.4.3 is nearly here, especially in light of the battery issue related to camera:

That post explains why using tasker to automatically toggle off mobile data makes the problem go away. I've been doing it so long I almost forgot there was a problem
[Nexus 5 Q&A, Help & Troubleshooting] TheFluffyOne:
Yes, fits perfectly with the issues I've seen. My work SIM was restricted to 2G, and I was seeing the slow performance issues all the time. 3G was finally enabled on that SIM recently and I don't think I've seen the performance problems since.
[Nexus 5 Q&A, Help & Troubleshooting] sanderhendriks0@gmail.com:
I want to try the script in tasker but I can't find the right tasks.

When I'm in the app I can add a new profile but then I have to chose between application/day/event/location/state/time.

Because the instruction are differrent I chose to add a task and then gave it a name. Next I have chosen the action 'net' but in the 'select net action'

I could not find 'wifi connected'. Probably I'm doing something wrong. Can anyone help me?
[Nexus 5 Q&A, Help & Troubleshooting] t.zakaria:
i found the issue and the solution

ok guys, I have the same issue with the phone, I noticed that it makes my router slow and this affect other devices like my iPad and my computer... Anyway the issue was that the nexus 5 try to backup data over wifi, this cause the upload speed to be slow and doesn't give much room for other requests from other devices to be served

What I did is this, I went to setting then Data usage then select wi-Fi then up there is a menu Uncheck Auto-Sync data

This worked for me, what a relief, when you feel you need to backup try to check it back when you go to sleep or when you don't need to use the Internet.

Let me know if this helped you.
[Nexus 5 Q&A, Help & Troubleshooting] rand0m_insanity:
I have this issue as well. I have done most things recommended in this thread except for a factory reset. I have concluded that it is the device, not my network equipment that is at fault.

It really is odd that I only get 3mbps max on my device where other devices including my nexus 7 2013 almost maxes out my wifi. I have tried streaming movies from my NAS and still get locked to a 3mbps speed. Therefore, streaming HD movies result to continuous buffering to almost unplayable.

I have restored settings from Google when I first set this device up, so I will report back after a factory reset.

Edit:

Okay, so I did a factory reset and did not restore my backup from Google servers. It still has not solved the slow Wifi at all. Well, there was a very slight improvement now that I can reach just a smidge above 3mbps. Like around 3.1-3.4mbps. This issue annoys and bothers me so much, and it seems there is no other fix as it is a hardware issue?

It irks me more that I have older devices that have wifi speeds way faster than this Nexus 5. Downloading or updating apps is such a pain as well.
[Nexus 5 Q&A, Help & Troubleshooting] Slarrybartfast:
Possible fix?

I found that my wireless charging caused an issue. Ifter partially charging I lost my WiFi speeds and was down to .5 download speed. Just fully charged wirelessly and speeds are back. Maybe this will help some folks
[Nexus 5 Q&A, Help & Troubleshooting] Schrotty35:
I get my Nexus 5x and and i have a very slow speed with Wlan 2,4Ghz and 5Ghzs. I have reboot devices, have flash the latest Nexus Image and i have restart the Router but not help.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I'm seeing 20+ down after a reboot and after time 7mb down. Resetting wifi doesn't help, must actually reboot.
[Nexus 5 Q&A, Help & Troubleshooting] t2002:
I received a new phone. The issue remains. I can't believe there aren't more people noticing this - this happens when accessing 3 different access points and with 2 phones.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Are there any claims of people directly saying it's not an issue? Or is it more of a case of those with the problem aren't completely dead in the water so they just aren't speaking out? Basically they aren't feeling the pain?
[Nexus 5 Q&A, Help & Troubleshooting] t2002:
Is true. I noticed that resetting the router rather than the phone also returns speeds too normal.
[Nexus 5 Q&A, Help & Troubleshooting] chadd74:
I have also noticed extreme slow downs. To the point that it seemed not even connected. Odd thing is, it seems to also be affecting my N10 also. The issue didn't arise until my N5 was put into the mix. I also have a Netgear router.

I originally had the same IP address from my previous HTC (which died so its not conflicting) I changed the IP and I can't recall any issues since but it hasn't been a very long sample time.
[Nexus 5 Q&A, Help & Troubleshooting] Solutions Etcetera:
I had this quite consistently on my Nexus 4 and 7. I monkeyed around with a number of settings which seemed to help temporarily, but the behavior eventually returned.

The last two things I did have (so far) fixed it permanently. They were:

1.) changed the default channels on the router to the other end of the spectrum for both 2 and 5 ghz bands

2.) My AEBS by default sets the same ssid for both bands. I assigned a different name to the 5ghz band so that 2ghz and 5ghz bands shows up under wifi settings as two different AP's.

3.) Set wifi frequency band setting to auto.

Not sure exactly which of these did the trick, but am guessing 2 and 3.
[Nexus 5 Q&A, Help & Troubleshooting] LNJ:
This happened on my Optimus G as well. The speed test indicates a drop to 1/4th of the real speed but upload speeds remain constant.

However browsing and actual download speed don't seem to be affected. Only speed test speeds. My laptop and Note 2 show the correct speeds on the tests.

Maybe it's just throttling itself or something.

But I don't care anymore cause the real world wifi speed is consistent.
[Nexus 5 Q&A, Help & Troubleshooting] MarcoMontreal1:
Wifi has been crazy fast for me , no slow down whatsoever
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
How do you know browsing and download aren't affected? Did you measure it some other way?
[Nexus 5 Q&A, Help & Troubleshooting] f0000d:
Yeah I can confirm that Nexus 4s also have the issue on my network for whatever reason.
[Nexus 5 Q&A, Help & Troubleshooting] Chad_Petree:
So I'm not crazy, I was feeling that wifi was feeling quite slow while using the phone and now I switched to my laptop and ... what a difference, damn :crying:
[Nexus 5 Q&A, Help & Troubleshooting] t2002:
Not to be defeated, I'm trying another router. If that fails I've got an ancient g only Netgear one to try!
[Nexus 5 Q&A, Help & Troubleshooting] chadd74:
Have read that if using a router that has 5ghz band that can be the issue. I'm keeping all my devices to 2.4 only. Maybe even shut the 5ghz off.
[Nexus 5 Q&A, Help & Troubleshooting] LNJ:
Cause my download speeds for torrents max out the same on the N5 and my laptop. About 2.3 MBps.
[Nexus 5 Q&A, Help & Troubleshooting] Solutions Etcetera:
I'm guessing that is a limit of the torrent. Modern wifi should support many times that.
[Nexus 5 Q&A, Help & Troubleshooting] t2002:
Now tried 4 different access points, 2 nexus 5s. Still the same. On my work connection I was downloading from the play store at around 50 Kbps earlier, on the 30 Mbps connection!

I think I will have to return for a refund but to get what?
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
The nexus phones with a new version of Android are almost always squirrelly when they first come out. I'm not sure how long it will take for an update that fixes it but ultimately they do eventually fix it. If you don't want to wait then I would avoid a kitkat phone for a while. Too bad, in your case, that there isn't a factory 4.3 you can load on your N5 while this stuff gets sorted out.
[Nexus 5 Q&A, Help & Troubleshooting] LNJ:
It's a limitation of the internet speed. Which at the time was 20Mbps. So my download speed of 2.3MBps is quite good.

For you guys running a 2.4Ghz router, try changing your channel width to 20mhz only if you have it set as 20/40mhz.
[Nexus 5 Q&A, Help & Troubleshooting] TheFluffyOne:
I'm still seeing this issue on the Nexus 4 after, what, 11 months? There's never a guarantee of a fix when Google's involved :(
[Nexus 5 Q&A, Help & Troubleshooting] Solutions Etcetera:
My point was that using internet-based resources for testing wifi speeds is inherently flaky. Set up a server on your lan for more accurate measurements.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
not saying it doesn't happen but I don’t think it's the norm.
[Nexus 5 Q&A, Help & Troubleshooting] bluegizmo83:
I'm seeing the exact same problem on my new Nexus 5 as well. My wifi speed will be really fast when I first turn the phone on, but after an unknown amount of time (seems like a few hours) then my wifi gets EXTREMELY slow, almost to the point of not working at all. The only way I've been able to get it to speed back up is to power the phone off and then back on again.
[Nexus 5 Q&A, Help & Troubleshooting] floriko:
my nexus 5 sometimes loses connection to wifis...I can't connect to any then and it says "Saved, secured with WPA2(or other security mode)"

Only solution is to empty the cache of the google search app..then it is running normally again. Should I open a new thread or is it maybe an related issue?

You might wanna try weather clearing Google Search cache also helps here.
[Nexus 5 Q&A, Help & Troubleshooting] TheFluffyOne:
Sounds like a different issue to me.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Has anyone noticed any kind of pattern as to when it gets slow? Mine is normal after a reboot and gets unbearable slow sometime later. Problem is I can't identify what apps or other factors triggers it to go into slow mode. All of I sudden I just notice that is running slow as a dog.
[Nexus 5 Q&A, Help & Troubleshooting] opencube:
Ive also been noticing the same issue.

Data seems really slow on Chrome and viewing page previews on Falcon Widget.

A restart quickened things back to normal.

its not just wifi for me, 3G also seems slower than normal too.
[Nexus 5 Q&A, Help & Troubleshooting] t2002:
Random for me. Can be fine for a couple of hours. Then this morning, as the auto-update of a couple of apps started straight after turning the phone on, it was slow straight away until toggling off then on again.

N5 with Netgear R6300

The same issue here,

after boot I get 10Mbps and after some time I max out at 1.99Mbps

This is a real issue for me 'cause I'm not able to see youtube in HD without buffering

I have to reboot to reach full speed again

Never had problems with HTC One S
[Nexus 5 Q&A, Help & Troubleshooting] RyYYZ:
My system:

cable internet, nominally 20 Mbps down, 10 up.

NetGear WNDR3700v4 router configured for 2.4 and 5 GHz

2012 Nexus 7 connected (on 2.4, of course)

Nexus 5 connected on 2.4 or 5

Slow downs are unpredictable, and what causes it to go back to normal, I'm not sure. At times I have thought it was rebooting the phone, or router, or just disabling and re-enabling wi-fi on the phone, but I can't really pin it down.

Running Speedtest, I will see the download "pulse", with the rate (esp. on download) wavering between something close to normal, and something quite low, averaging out at the end at maybe around 50% of full speed. Uploads are affected, but not as severely, often coming in at ~70-80% of normal.

At the same time that my N5 is experiencing this slow-down (while on 2.4 GHz), my N7 can still download at full speed (using Speedtest). I don't mean at the same time that the N5 is downloading, but alternating Speedtest runs between the two. Also, when my N5's wifi is slow, I can still run speedtest from my desktop which is wired to the router, and Speedtest results are as usual.

And then, after some seemingly random period of time, download speeds will return to normal, only to eventually fall off again.

Yes, it does seem like the N5 is not always playing nicely with the router, and possibly a firmware fix to the N5 will resolve it. If LG/Google bother to look into it.

[Nexus 5 Q&A, Help & Troubleshooting] DokoBG1:
I just tested my N5 and I got a 32Mbps down and 2Mbps up over WiFi (My plan is 50Mbps down and 3Mbps up). I tested this on my NETGEAR WNDR3700 router with (2.4GHz b/g/n) antenna only. Channel is set to Auto from my router. I hope this helps someone...
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
one-time tests don't really address this issue. You need to test several times during hours of use and see if over time, since the last fresh reboot, the speed is decaying.
[Nexus 5 Q&A, Help & Troubleshooting] DokoBG1:
I'll keep an eye on it but ever since i got it on the 12th its been 90% on WiFi for download of everything. Haven't noticed any problems so far.
[Nexus 5 Q&A, Help & Troubleshooting] RyYYZ:
Mystery solved, for my case at least.

WiFi is fine. I can copy files from my PC's media server at over 10 Mbps, consistently. Same for downloads from the internet, for example Google play, at about 2.3 MBps (20 Mbps connection).

Back to Speedtest. I discovered it is only slow when I have set the location mode to Battery Saving. If High accuracy or Device only (ie GPS) is enabled it works fine. This seems to be quite consistent.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Mine, with erradic speed tests, has been set to high accuracy all along :confused:
[Nexus 5 Q&A, Help & Troubleshooting] RyYYZ:
How's your speed on, say, large downloads from Google play? Do you have a local source you can also test with, like a PC with media shared? That would help narrow it down. I realized I was barking up the wrong tree when I tested other downloads which were working a at expected speeds. My issue seems to be just the Speedtest app, but that may not be the case for anyone else.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Interesting theory. Have you tried the new fcc speedtest. It seems to confirm Speedtest.nets numbers. I haven't setup a private test but I certainly could with a little time.

Here's a link to the new fcc speed test.

https://play.google.com/store/apps/details?id=com.samknows.fcc
[Nexus 5 Q&A, Help & Troubleshooting] RyYYZ:
Can't run it from here. Probably US only.

Anyway, the behavior is quite reproducible for me. Disable GPS, start Speedtest, run a test, it's slow. Re-enable GPS and run again, and speed is good. Speed in Speedtest may come back on its own after a while, but the above sequence works for me consistently. Other tests don't seem to suggest any Wi-Fi slow down. For example the "The internet speed test" app.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
Ok, I'm seeing at least part of my problem and I should have remembered that it was an issue on older Nexus phones.

It varies depending on the particular access point (I have different models) but having bluetooth on and connected cuts my speed consistently by 50% on my fasted access point and by around 30% on the others.

For me a big deal because I only use a bluetooth headset. Its literally on whenever I'm using the device.

I ran the tests 5 times in a row with and without bluetooth on and connected. Repeated on different accesd points.
[Nexus 5 Q&A, Help & Troubleshooting] TheFluffyOne:
I believe that is a different issue. There have been Bluetooth/WiFi coexistence issues on the Nexus 4 for sure (recently fixed for some in the 4.3 update, but at the expense of slower throughput when BT is enabled).

The main slowdown issue discussed here doesn't -- in my experience -- relate to the use of Bluetooth. I can go days without BT and still see these slowdowns after some seemingly random period of time.
[Nexus 5 Q&A, Help & Troubleshooting] NCguy:
I'm not sure that BT explains 100% of my degradation just yet. I should know in a few days if there are also other things going on. But the symptoms are very similar and just as problematic.

At a minimum it may help people rule out whether their speed reduction is due to BT or more like the issues you are seeing. It just shows how much attention wifi needs on this device.
