[Q] Slow download speed on a fast internet connection with an excellent wifi signal

I just wrote a long post detailing my problem and lost it all the instant I hit the 'submit' button because the forum timed out. AHHH. I'm sure some of you have been there and know the feeling!
Anyway, I just came across the revelation today that there is something seriously wrong with the download speed of my Infinity tablet. For as long as I can remember, I have had trouble watching Youtube videos. Occasionally, they would play fine. But more often than not, the streams would constantly pause every couple of seconds to buffer -- making the videos unwatchable. This behavior was the same on all the channels I visited. I don't watch Youtube videos that often, but it has finally irritated me enough to investigate it.
According to my tablet's wifi settings, my link speed is 39Mbps from my usual location. I brought the tablet to the same room as the router (an Asus RT-16) and the link speed increased to 65Mbps, but this did not solve the constant buffering problem. I then performed a factory reset and left my tablet clean, only downloading updates for the stock apps including Youtube. Unfortunately, the problem remained.
Now this is where things get interesting. I have a 12Mbps internet connection. I went to speedtest.net on my desktop PC and it reported 11.54Mbps down and 1.48Mbps up. Quite reasonable. Then I downloaded the Speedtest app onto my Infinity. Even with a 65Mbps link speed, I could not achieve more than 2.02Mbps down and 1.57Mbps up on the same server I tested my desktop. I then tried other nearby servers, and all them were between 1.65Mbps and 2.0Mbps down. 2.02Mbps was the fastest download speed I could achieve.
For a comparison, I then ran Speedtest on my Galaxy Nexus phone. It achieved 9.33Mbps down and 1.61Mbps up.
Any ideas why my Infinity can only reach a download speed of 2.02Mbps, even with a 65Mbps link speed?

I just downloaded the app Speedtest.net and ran a test. The results are 15526kbps download and 2806kbps upload. I used to have that problem with the stock rom. Currently, I am using custom rom and some tweaks with the tablet's network. It does not have the buffering problem any more. So far, I have no problem with streaming movies or youtube unless three or more devices sharing the same network in my house. My current settings on my tablet are Cromi X V4.6.6 and Hundsbuah V3.0.6 OC CPU at 1.8G all cores, UV about 35mV, and GPU at 700M. To answer your question, there are a lot of things could affect the network. These are a few major problems: the buffersize setting, low RAM memory, slow I/O, and other poor factory setting came with the TF700T. There are a lot of good information scattering everywhere on this website. With some research, you can fine tune your device. Good luck.

Thanks for the detailed response LMK. To make things more confusing, I just re-ran the speedtest about 5 hours after the first series of tests and the download speed is now 9.81Mbps down and 1.64Mbps up. So this is an intermittent issue which explains why I can sometimes watch Youtube videos without issue. I have been sorely tempted to unlock my device, but I have a stuck pixel and I was worried other hardware issues might creep up during the warranty period.

I unlocked my device after a few day of purchase. I never attempt to tweak with stock rom. Therefore, I don't know if I can help you further. There are a lot of experts on this site. They will give you some good advises on this topic. If you some how can access to build.prop and init.d, those area where I tweaked my network. Maybe, you can access those files with rooted. You probably can find some answer with searching on this site.

Could be RFI (Radio Frequency Interference). Look around your house for wireless devices in the same freq range as your wifi router. Usually 2.4ghz. Cordless phones, baby room monitors, wireless speakers and sometimes microwave ovens. If you have any of these types of devices unplug them all then run your speed tests again several time to the same site. I get good speeds on mine using the speedtest app. Usually 19-21 mb on a U-Verse 24mb connection. But I had problems when I installed a rear wireless speaker adapter from Radio Shack for my surround sound system. It knocked me down to 3-4 mb. I beat my brains out (the few I have) for days until I unplugged ALL wireless devices (not PCs) and then one at a time plugged them back up running speedtests at the addition of each device. Then I discovered the RS wireless adapter was the culpret. Lucky for me it has a switch for three different channels. Changing the channel on it cured my problem. Placing my router on wireless channel 4 helped even more. Neighbors on either side of me are on ch 11. I also suspect the RS device was just about there too.
Just a passing thought. I hope you get your problem solved.
BTW My TF700 is completely stock.

Any Help is Welcome

Perplexing.
I have this bufferng situation also, if that's what is the culprit.
Solved my up/dn problem by removing my access point
I am 65mbps 13-24 mbps but can not stream YouTube etc. Plays a bt then the hourglass.
I think wi-fi interference would hurt the 65mbps connection speed not the upload/download speed.
I have a linksys router and the special Linksys modem built for Comcast system.
I can only look at system or apps conflict as the culprit but damn if I can find it.
I have been CROMi since Scot's incarnation.
Any Help is Welcome, thanx

Strange. On my stock TF700, with a good 65Mbps connection, with Speedtest I see 19Mbps down and 5Mbps or so up, about the same as my Nexus 7 and laptop. Are you using the same test server for all of your tests?

Improved 5GHZ wifi performance with one setting...maybe?

So 3 things prevent this phone from being perfect for me.
#1 Lack of NFC (but I knew about it so nothing I can do).
#2 Bad Wifi speeds at 5Ghz
#3 GPS not working until reboot issues.
So for the Wifi issue, from the same location that I was getting over 100Mb downloads from my Note 10.1 and 60-70 on my Xperia Z Ultra, this phone was barely making it to 25-30. That created issues as it will start buffering even watching 1080p youtube videos.
Switching to 2.4 was more stable but barely enough speed.
So I went into the developer options and dsiabled the option that says " Use Legacy DHCP client" and now my speeds are over 60Mb from the same location. No more buffering or slow app downloads!
Not sure if it will vary since the devices picky but if you are having a similar issue, then it is worth trying.
I am currently testing a couple of things for the GPS to see if it helps. At least this morning, it was working but we shall see if it works tomorrow and so on.

Thanks for posting, and keep us updated especially on the GPS issue!

I have problems with this setting on wlan now. If there is a strong unknown 5 ghz wlan in the near and I want to stay in a known 2,4 wlan.
My x2 tries to swap to the stronger and faster wlan and recognizes that it does not know a password for it. Then it will return to my known wlan and login automatically.
This happens regulary after a few seconds.
At home I have one 5 ghz wlan and 2 with 2,4 ghz. All have the same SSID and password. So no problem there.
Any ideas to force my device to stay in the 2,4 wlan on the other location with the unknown network?
If I switch back to the 'old' lollipop dhcp client setting the problem goes away.
It just tests once the new network and if the password is not available, it stops checking this again and again.
On my nexus 6p this problem is not present, so there could be a solution for the x2, too.
My device: 701->703 B211 xposed 86

Huawei is able to find a solution to this if they wanted to and send an update, so it's disappointing that they make no efforts to do so!

phone speed & tether speed

hello I have been studying this issue for about a couple of weeks & still can't find no answer to this. The speed test on my phone you can see is pretty fast, BUT when I use T-Mobile hotspot tether why is it slower then back in the AOL dail up days 56K. I don't know what can I do that can at least give my hotspot tether a minimum of 2Mbps. Can anybody help me out with this issue appreviate it.

There are a lot of different things that could cause this. First of all you need to know that every provider recognize when you are doing a speedtest and they give the maximum that is available only for good test results. That doesnt mean that you could access the internet with that speed. Second, the speed of the wifi connection between your phone and pc could be very bad espacialy when you place your phone very close to the pc, for a good wifi connection it should be minimum 1m distance. And there are a lot of other things that could impact the speed like apps using internet on your phone or background updates on pc or a hundred other things. Nobody can tell you for sure whats causing this, you just can play around with it for a while place it on different postitions or deactivate apps and so on and so on...

Thanks for the food for thought. Correct me if im wrong the speeds that you do in speedtest results are the physical speed you would be using from your phone internet right or it would be a very lengthy lag when streaming videos & downloading apps. At 22 mbps a app that is 21mb would download just about soon as you click it. Sohow would these speedtest results not be the physical testing usage. I thought it was other 3rd party apps to bypass the throttling. I am gonna see if I can fumble somewhere in the internal advance settings. Cause its something Tmobile have if i purchase the unlimjted tether i heard i get the full bandwidth speed & thats the goal I do want to work on to achieve.

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 of other devices drops when I download a huge file

Hi everyone!
I'll try my best to explain what the issue is as my level of expertise when it comes to tech stuff is not advanced.
I have uTorrent installed on my Xiaomi Device.
My internet works fine. I have VDSL plan 20 Mbps.
Whenever I download a uTorrent file on my Xiaomi device, it works ok, the download speed is ok. It reaches 2.5 MBps, just the right download speed for my VDSL plan.
However, I have 1 other device (Samsung Phone)
While the Xiaomi Device is downloading the file from its uTorrent app, when I try to go to the internet with this Samsung device, it still detects the wifi signal, but it gives me an error saying my connection has timed out, and that little exclamation mark thing on the wifi symbol appears. When I go to youtube for instance, my Samsung device tells me I'm offline. Now when I look at my Xiaomi device, the download is still running.
Whenever I stop the uTorrent app, the internet comes back in my Samsung device. So I was able to rule out that the problem is the uTorrent. However, this never happened before. My modem router just got replaced as upgraded my ISP's plan. Before, I download things on the internet with no problem at all.
What I did so far?
I adjusted uTorrent's maximum download limit to just 500 KBps, as I was thinking that if I set it to Maximum, it will consume my bandwidth. But no, this didn't work. I was still getting the same trouble.
Hope you guys can help me. Thank you!
