Hello,
I have posed this problem on the S4 section, but I got no answer, and it looks to be a global Android KitKat issue...
I have a Galaxy S4 GT-I9505 with the newest firmware from Samsung I9505XXUGNF1 (Kitkat 4.4.2) rooted with TowelRoot. My router is a Asus RT-AC66U to which the S4 connects with max speed of 433 Mbps. My internet connection is 120 Mbps.
When I do a speedtest on the S4 I get results of ~120 Mbps. When I download a file over the internet I get full download speeds ~8 MB/s, but when I'm downloading a file over LAN from the disk connected directly to the router I get download speed only of ~20Mbps (2.4 MB/s) which very much sucks!
The same is happening to my Brand new Galaxy Tab S.
It is connecting to the WiFi router with 866Mbps, and files inside the network are download only at ~3 MB/s
My Laptop with Windows 7 have only a N network card, and connects to the router with max 300 Mbps and when I download the same file I get over 7.5 MB/s!! (~65 Mbps).
Speedtest also shows results of over 110 Mbps...
I remember when the phone was new, and it had Android 4.2 (~10 months ago), I had LAN download speeds of over 7-9 MB/s...
I tried with different file managers like X-Plore and others, but it looks like it is not the app problem.
When downloading a file from the laptop, the download speeds get even worst!... less than 1 MB/s!
I have enabled Location and set on "GPS only" in both, the S4 and Tab S
does somebody have the same issue and know what could be the problem?

The problem is now solved by installing newest version of X-Plore v 3.66 https://play.google.com/store/apps/details?id=com.lonelycatgames.Xplore
LAN download speeds went from ~2.5 MB/S to ~14 MB/s (I think that the limit is now the Hard Drive plugged to a USB 2.0 port on the router)
Thank you Lonely Cat Games for solving this issue!!

Anyone test their speeds using Internet Connection Sharing? I did a bandwidth test from the phone and got 8.9 Mbits download and 3.6 Mbits upload. Then I then did a test from my laptop and I got 3.5 Mbits upload but my download would not go above 0.6 Mbits. Anyone else noticed this problem?
This is not slow, hsdpa gives 7.2 Mbps speeds only so expected

This phone is capable of 14.4 Mbps, not just 7.2 Mbps. My Carrier is capable of 21 Mbps. This was not the issue. The issue was getting over 8 Mbit/s download speeds on the Titan, but when using Internet Connection Sharing the speed would not be greater them 0.6 Mbit/s. This was tested right after the initial test. The upload speed was very similar though.
As is my understanding, you will never achieve the same speeds when using ICS.
When your phone is communicating with the internet, it is dealing with one lot of data being sent and one lot of data being returned.
But when connecting your computer via your phone, your phone has to take that data from your computer, then pass it on. So it is dealing with one lot of data to/from your computer, and another lot of data (the same data!) to/from the internet - So you are doubling the amount of work the phone does. Your phone only has the one radio chip for this data, so it has to alternate between all the incoming and outgoing data.
You get the same slow-down on home wifi networks if you use a wifi repeater.

I understand that it will be less, but to go from over 8 Mbits on the phone to 0.6 Mbits on my laptop is more then what one should expect as a penalty for connecting thru the phone.
Even with your example of using a wifi repeater the bandwidth is only halved, and that is because the link is using the same frequency band over both hops. In the case of the phone, Internet Connection Sharing is acting like a home router with the cell frequency side the equivalent of the wan port and the software is providing NAT to clients connected on the 2.4ghz wifi connection side so there is no penalty for using the same frequency band.
As I also stated the upload from the phone and the upload from my laptop are the same, around 3.5 Mbits. What I was asking is if other people have had this same discrepancy when using Internet Connection Sharing. Even if the results from just the phone were ignored, the fact that I only got 0.6 Mbits download vs 3.5 Mbits upload thru the phone tells me something is not working properly.
If anyone is seeing this discrepancy between upload and dowload speeds with Internet Connection Sharing let me know.

Have tried same SIM different phone? Different SIM same phone?
It could well be your provider!
Comcast wi-fi internet access : wife's s3, galaxy 8.0 tablet, and toshiba laptop all clocking around 30meg download speeds on speedtest.net, while my s4 will only clock 4-5megs. ALL four will upload same, about 6 meg. Verizon tech referred to Samsung tech who could only recommend a reset which did not help. The recent upgrade to android 4.3 also had no effect. Both s3 and s4 will clock similar 10-25 meg downloads on strong 4g lte connection. Any thoughts?
I'm trying to diagnose why my transfer speeds seem to be slow on my HTC One running ARHD 40.3 with latest firmware
I'm downloading one or 2 files totaling 1.56 GB from my Synology NAS device that is plugged into a gigabit switch then ran to my gigabit router which has a gigabit switch on it. I'm connected to the router via 802.11ac (router is Linksys EA6200) on the 5 Ghz band I am reporting anywhere from 80 Mbit to 433 Mbit connection, yet I've only ever seen said files download at 3.5MB/sec, or about 25 Mbit.
Why is this?
If I wire up to my NAS directly and copy files over USB it's considerably faster, so it's not crappy read/write speeds of storage media, it's something with wireless, i can copy stuff to from about 20 times faster from my wired computer as well
Thanks

Have you tried bringing your phone really close to the router while trying to download? You may be experiencing signal attenuation from walls and such.
No matter what i do I can only get 65Mbits (10Meg) per second (and thats on 5Ghz) Is this the max speed the phone can handle? I have 150Mbit per second internet connection.
Im good here...

How did you attach your screenshot, I'm trying to add mine and can't find an option to add an attachment.
NEed to be a bit more specific....
Airplane mode on, then wifi on, speed test, should usually get you 80mbps or higher..
The real test is doing a SMB or internal network transfer... can only get 5-8MB if I am lucky...
First phone was 500k for internal SMB. Speed test always shows great speed going out, but never on a local network..
My speed is super ok WiFi up 380 / down 411 Mbps
I get the advertisex ISP speed (120mpbs) using the speedtest app.
SMB I just about get 1 MB/s
Are you getting 8 MBytes/s ie 64 mbps? I would be very happy that. I warch videos by running the straight of a network drive, the get choppy.
Hi.
What wifi speeds is the galaxy S9 plus capable of. I have Gigabit broadband and the max speed I can get on the 5Ghz is 160mbps.
The router from provider isn't the best
Will I get much higher speeds if I upgraded my router or purchased a wireless access point connected to 1gb LAN port and access point capable of 1300mbps on 5Ghz?
Thanks
I have 500Mbps from my provider plus custom router(DIR-882) AC2600 MU-MIMO. And this is what I can get(400Mbps) from room next to my router(3m + wall/door) : http://www.speedtest.net/my-result/a/4290259062
I've gotten up to about 530mbps once in a while. More typically just under 500.
You need a high end router in order to get higher speeds over WiFi
Try to change to a not frequented channel and set the Bandwith to 80MHz.
I can get 800Mbit/s when nobody other is using the WiFi.
Allways 866Mbps guys.
Tp-Link Vr900
But when i send videos to the nas usually the speed is 40mb/s
Maybe your drive in the NAS can only write with 40MB/s. Remember, that 40MB/s are 320Mbit/s.

I think that with 1+6 i was writing with 50-60mb/s.
Also my nas can write with 1gbit connection (lan) 100mb/s.
Do you have any sort of an extra firewall on your phone?

My S9+ will connect via 5GHz to my Netgear R8500 at a LAN speed of 1083Mbps - but you have to be within 3m/10ft to get that speed. It falls back to 866Mbps pretty quickly if you are only just a little further away.
Real-world download/throughput performance will be lower.
