Slow Wifi download

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.

[Q] Google Play Store WiFi download super-duper slow

Hi guys, I just done resetting my OPO to everything stock 44S, but when I tried downloading and install back my apps, it was ridiculously slow while downloading the apps. I checked my net is performing perfectly at 20Mbps, but Playstore download apps at 50-100Kbps I was like WTF??? I tried change DNS doesn't work either, but on mobile data is super fast, just like normal just WiFi. I tried my second phone WiFi also slow like hell but watch youtube etc is smooth. Is it possible Google side problem or my ISP problem?

If everything else works fine I would guess it's a Google problem. Or the routing to your place isn't that good? Are you using a VPN?

I was thinking the same thing. I got my OPO last Friday and I've been flashing roms all weekend. I also noticed that the Play Store download speed was ridiculously slow on wifi and LTE. I have AT&T and I also flashed Ark kernel. After about 2-3 hours, no matter what rom I was on, the Play Store apps sped up. I thought my issue had something to do with me going from 11S to 11 to 12 all weekend. (I had to find what worked for me) But it seems that irrespective of the kernel, cm version, and gapps I was using, the dl speed just popped back in gear after time.
Sorry I couldn't be of more assistance but my only solution was time. How long have you let your phone idle?

I think idle time doesn't matter, okay.... I tried with my friend's phone, it's also same, very very slow download speed, so must be Google side...

Like what others have said. If you had another device and play store downloads was also slow. Your home isp probably bad poor routing to the servers causing it to lag.
Some other tips. Disable wifi optimization if you haven't. Toggle wifi on and off and then try a download again. Restart your modem and router.

You can test the speed with a normal dl from a fast Server, bunt i think it was a Google Problem

I just did some updates to my apps

I didn't see this issue with my 5113. It was rock steady wifi-wise. Are you sure it is related to the ROM and not some stray software conflict?

is there a way to identify a sofware conflict ?
the point is that when i turn wifi on / off, Wifi works fine for a period of time of variable lenght.

Solved
Finally , i ve changed some parameter and it seems to work perfectly fine
Parameter I changed is the following :
In WiFi advanced parameter I have unchecked WiFi optimisation
Works fine for me ?

Wifi download's speed using Google services like backup and play store is slow

Hi. Thanks for this guide. I was able to install Android 9 though VPN. I was having a problem with background apps even with adaptative battery off. I solved it by entering at the list of apps/procces and disable the optimization on them. Everything now is ok except WiFi download speed using Google services. Download's speed in Google play store is 0.1 mb/a when normally is 6 mbps on android oreo(previous version). When I turn off the Phone and then i turn on, WhatsApp starts to do a security backup at its normal speed but after a few seconds the download speed is 0.1 mbps.But the strange thing is that on 4g mobile data it downloads normally. I don't know what to do. I cleared the caché and data from Google services and nothing. Is this a bug or something? My Phone is not rooted and the bootloader is locked.
Edit: I reset my phone to default settings. It still has Android 9. The first time did not make difference. The second time the download speed was back to normal but after an hour after the reset it went back to 0.1 mb/s.
Edit: If i turn on airplane mode the download speed is at full speed. Can someone explain me why is this happening pls? Thanks.
EDIT: Solved by turning off location: settings->security and location->location-> turn off by sliding the slider. I don't know if this options have these name. I have my phone in another language. I will update my post. This solution is not a real solution since you turn off location and some apps need it.

It's happening to me too. Will wait for update (on the post or SW).

Here it's happening only on 2.4Ghz network, using 5Ghz it's normal speed... Other devices are working fine on the same 2.4 hotspot, so definitely a bug.

Found out that if you disable locations services (bt also helps) the download speeds goes back to "normal".

Sorry! Have not noticed that. There are some bugs that need to be fixed. Will either downgrade out wait a little more to see if a solution/update is provided.

WIFI connection disconectting automically while playing pubg mobile.

** Need Help **
I'm using Phoenix OS for playing PUBG Mobile. But sometimes while playing the WIFI connection of phoenix os automatically gets disconnected. Then I have to reconnect it again. It's really disturbing -_- .
My router is fully okay. Cause I don't face this issue on my other OS. I don't know if this problem has any relation with my L speed installation.

My wifi is restarting after 3 seconds connected to a network. It started to happen today. I installed the "L Speed" app from Magisk yesterday. Any idea of how to solve this? I don't want to format everything because of my WearOS.

Well after all, run your OS for a while and let it disconnect 5-10times. Get the logcat then and attach here.

Hey there, i know this is a bit off but im here for almost the same problem.So i am using oneplus 3 android pie and i have only installed l speed recently. So before i installed this app my connection was stable but after i install this app i noticed instability in my connection. The following situation are some example :
1.When viewing whatsapp status it used to only take a few minutes before im able to see the status but after install it i need to wait for a long time. this shows that my phones connection are not focusing on whatsapp because when i try to download anything, the download will take a few seconds then the download will start downloading with a bit faster speed than usual so i know that my wifi is not the problem but its a problem with my phone.
2.Pubg mobile connection became really unstable because when i open the game to main screen it constantly says that server is not responding or rewuest timed out but at the same time when i download resources in the game it download as usual( i can see at my status bar on my phone the internet speed)this leads me to conclude that the L speed does make my phone download speed a bit better but in the cost of stabilty its making my phone connection not stable. I think that the tweak made my phone focus the internet on downloading the resources for the pubg but it made my phone not giving any internet or maybe if it give, only a little internet to the app itself to load the main screen.
For your jnformation, after i realised this problem, i reverted all the setting in the app then uninstalled the app and reboot but the connection instability still occurs so i think maybe there are some adjusment made by the app but not reverted back in my system. Oh and one more, i tried looking for the init.d folder incase i need to delete scripts but i can only see init folder and the init.d folder is no where to be found. And onemore for your info, when i installed the L speed i used the balance profile and in the LNET section, i only turned on the RIL tweak, tcp and also net speed+ and for the net buffer i occasionally change it between small, big and default.I hope somebody can help me resolve this problem.My only hope is that my internet connection on my OP3 returns tu its original state.
