Is the phone's MODEM speed limited to about 50mb/s?
My internet speed is 70mb/s as measured on my computer WiFi connected to my router. The max speed the phone is showing is 48-49mb/s while sitting right next to the computer.
Is there a (build.prop) mod that can speed up the phone's WiFi speed? The phone is rooted.
Your computer could be using a different wifi band than your phone. Computer's speed often differ from the phone. Also both the devices have different types of antenna and operating power levels. I don't think messing with the build.prop would do much.
Let me ask the question differently. Is anyone getting faster than 50mbps on this phone? I am not.
The phone is rooted running 2/1/19 update OEM ROM Potter. Router b/g/n broadcasting at 2.4gHz only. Internet download speed is 90-100mbps on the computer. Phone and computer speeds measured 2 feet away from the router using the same Comcast speedtest app..

I used 2 apps to compare. SpeedTest.net and Xtremelabs Speedtest. I have a 2Mb connection and it test correct on my laptop both wired and wireless but with those 2 apps, my DHD reports ~223Kbits. I run the test several times (around 20 times) and it always shows similar results. Only one run which I did after returning home showed 2Mb. Never saw the same again.
Anyone noticed the same? maybe it's the way those apps measure or is it my phone?
You tested what ? Your phone connected via WiFi to your home internet, or your phone GSM/EDGE/HSPA connection ?
The home internet can be explained by downloading something else through other computers on your network or by lower wifi speed negitiated between your phone and wifi router.
If you measured your mobile connection, it could be that you simply don't have HSPA inside your house and it drops to EDGE or UMTS -> sub-300kbit speeds.

thanks,
I already know what you mention.
I test wifi connection. It is supposed to check data transfer rate between my local wifi connection and the Internet. I do the same on my laptop at same location and get 2Mbits.
My mobile connection here is unstable=(sometimes GPRS sometimes 3G) so I won't bother to test from here. I am only concerned about wifi results.
Are you getting those correct?
In case of WiFi, there are many factors which can slow it down. But since you are using the WiFi on your laptop too, we can exclude factors like interference from other WiFi networks or any other factors which could make your connection to your router problematic.
This brings it down to the phone itself. Now the questions is - do you use any kind of WiFi security ? If yes, can you turn it off just for test (yes, i'm asking you to have a unsecured WiFi network for a while). This way you can exclude the possibility that it's the encryption which slows you down. If it will speed up, your problem lies in encryption, and that brings up the question if you have USB debugging enabled or not - you should have, as it fixes the 100% CPU usage bug. If your CPU is used up thanks to this bug, then of course all encryption is slower, which means your data transfer is slower.

Strange, you know what? I connected to USB in order to sync and verify USB debugging (it was on anyway) but after sync, I run the test and it shows above 2mbits but one time it showed 1,2Mbits. The same goes with xtremelabs speedtest.
Now, I can't tell if it's due to the usb connection. I restarted my phone earlier anyway and it still measured slow connection at the time that my laptop was measuring high.
I ran the test so many times that I am 99% sure that the only difference this time was the connection to usb for sync.
I can't exaplain this, I don't know if you can
Then, after a while I try again and it goes down again. I sync but still stays down so that's irrelevant.
I perform the same test on my laptop right after this one and from the same location and it's always high.
I don't know how to explain this
Hi,
I recently got myself a new Type N WiFi router. On my old B/G Wifi router my SGS connected with 54MBit/s as it is supposed to do.
I was expecting to see a connection speed of 300MBit/s now (I'm not talking about the effective transfer rate, just the connection speed) but instead my SGS connects with very variable speeds to the router but never exceeding 65MBit/s.
Is this normal or do I have to do some specific settings in the phone or in the router?
my notebook computer connected at 300Mb/s while my SGS is at 72Mbps. HD(720p) playback through network is smooth.
its normal, sgs has only one antenna, look it up, for 300 Mbit u need 3 antenna.

You are talking about the transfer rate, I asked instead about the connection speed. You might be able to see this logging into your router. Your slow transfer speed probably depends of the fact that you are connected with your PC through Wi-Fi too. Connect the PC by cable and your transfer speed will at least double.
Sent from my GT-I9000 using XDA App
my all-time maximum is 72Mbps
and its not even effective
when transferring files it uses about half of that speed
720p is indeed smooth
Hi,
I would like to ask if it's normal to have <1MBps wifi transfer rate on my Galaxy S4. I'm trying to transfer a movie file from my phone to my PC (gigabit-lan) via my TP-LINK N750 router.
I checked my phone and it's currently connected using 2.4Ghz spec with 72Mbps linkspeed. Theoretically.. the wifi transfer speed should be around 8MBps not <1MBps.
Any clues why my transfer speed is slow? My forte is more on network stuffs so I'm not really sure if my phone is causing the bottleneck here or not. See attached for reference.
Thanks guys!

I have the same issue across several different ROMs and modems. Laptop with external HD is connected to router with gigabit LAN, phone connected to router via wireless-N and I get roughly 1mbyte/s. However download speeds with my phone via WiFi is roughly 8 megabyte/s (fiber optic) so I know higher speeds are possible.
My other desktop PC achieves around 11-12megabytes through WiFi but my phone just gets nowhere near it.
Odd thing is when I stream videos to my phone though my WiFi from a hard drive the phone buffers at well over 5megabytes/s but file transfers are somehow limited... I could never figure this one out

Thanks Swizzy!
I also noticed this.. somehow I thought it was because of my router. So I decided to buy 450Mbps Dual Band router to test it. Unfortunately, it is still capped @ ~1MBps transfer rate even I used the 5Ghz spectrum
Complain to google
I have done some testing with a fast windows 7 system as the target and a Nexus 5 and an xperia neo v. I have also tested with XP and Linux smb clients. Basically the maximum I get get with stock 4.4.2 or 4.0.4 is about 4.5 Mbps (550KBps) pull down and 9Mbps push up. Wifi is 11g and XP gets 15 down and 19 up. openSUSE linux gets more or less the same as XP. The problem exists with ES Explorer and File Manager. I tried SFTP into linux with ES Explorer and that was a little slower. The standard USB transfer from windows explorer is really fast to the N5. This looks like a design or configuration problem in android 4. Complain to GOOGLE.
I am glad I found this just before I spent a lot of money on an ac router to speed up large wifi file transfers
So a device running pre version 4 should not have the limitation?
I have a Galaxy S4 with the newest firmware from samsung I9505XXUGNF1 (Kitkat 4.4.2). My router is a Asus RT-AC66U to which My S4 connects to with max speed of 433 Mbps. My internet connection is 120 Mbps.
When I do a speedtest on the S4 I get results of over 110 Mbps, 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 is very sucky!
My Laptop 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 4.3, I had LAN download speed of over 9-10 MB/s...
I tried with different file managers like X-Plore and others, but it looks like it is not the app problem. Maby is a KitKat problem??
In short blame Broadcom or Samsung for using Broadcom BCM4335's BCM4335 wifi chipset. You need to understand how 802.11n works. To achieve 300mbps speed, you will need 2-3 spatial antennas which can be found on modern laptops with Intel Wifi chipset (such as 6300). Our galaxy note has only one antenna (should be 1 for each radio band (a/n, b/g/n), but it is "N" compatible. Unfortunately this is a case of the manufacturer misleading it's customers ( I would say out right lying to us). Its is compatible with N, however it can not support N speeds, as far as I have seen all phones that claim 802.11n are actually limited to 65mbps. So really are not 802.11n at all, rather just a little faster than 802.11g.
part of the problem is the maximum number of data spatial streams the radio can use. Also assuming equal operating parameters to an 802.11g network achieving 54 megabits per second (on a single 20 MHz channel with one antenna), an 802.11n network can achieve 72 megabits per second (on a single 20 MHz channel with one antenna and 400 ns guard interval); 802.11n's speed may go up to 150 megabits per second if there aren't other Bluetooth, microwave or WiFi emissions in the neighborhood by using two 20 MHz channels in 40 MHz mode. If more antennas are used, then 802.11n can go up to 288 megabits per second in 20 MHz mode with four antennas, or 600 megabits per second in 40 MHz mode with four antennas and 400 ns guard interval. Because the 2.4 GHz band is seriously congested in most urban areas, 802.11n networks usually have more success in increasing data rate by utilizing more antennas in 20 MHz mode rather than by operating in the 40 MHz mode, as the 40 MHz mode requires a relatively free radio spectrum which is only available in rural areas away from cities. Thus, network engineers installing an 802.11n network should strive to select routers and wireless clients with the most antennas possible (one, two, three or four as specified by the 802.11n standard) and try to make sure that the network's bandwidth will be satisfactory even on the 20 MHz mode.
Data rates up to 600 Mbit/s are achieved only with the maximum of four spatial streams using one 40 MHz-wide channel. Various modulation schemes and coding rates are defined by the standard and are represented by a Modulation and Coding Scheme (MCS) index value. The table below shows the relationships between the variables that allow for the maximum data rate. GI (Guard Interval) : Timing between symbols.[6]

I see similar speeds on my S4 when doing wifi transwer. varies depending on which network i am on and what I am transferring to.
still faster than crappy USB connection..
@XeoNoX thank you for educational lesson.
WiFi Powersave mode
You may check if the WiFi power save mode is on. If it is on, you may turn it off and check if the speed improves.
To enter Service Menu, open dialer and press *#0011#
In the service menu, select menu > wifi
check if the WiFi power save mode is on or off. Turn it off.
If it was off, then you've wasted your time trying this
So I juse got Comcast 50mbps. Did speed test on Laptop and showing 57mbps max, did speed test on phone, showing only 34mbps. I even changed the channel on the router to the strongest signal and changed my phone signal to static in the adv wifi connection settings. Why is my phone not getting 50mbps also? Help
Just a guess here: power save...
A laptop can send more power to it's internal antenna to get better reception while the phone has a limit i suppose.
Have you tried your test with the phone being very close to the router?
Which software are you using to measure the speed?

I checked the power save option and I stand right in front of the router. At first my phone showed about 25 mbps and when I switch to static it went up a little. I'm using speedtest.net. Same speed test as my laptop. I would figure if my router is pushing out 57 mbps I should beable to get close to 50mbps on my phone. I can't get above 40 at all.
I have discovered that my US996 Unlocked and rooted device has typical down/up speeds of 90d/55u when the phone is not being charged. When the phone is connected to a charger the typical speeds are 400d/270u. This is very repeatable. The phone is 3 feet from the router. am using speed.net and the ping is 4 to 5 ms for both configurations. If I start the test with no charger and plug the charger in during the test the speed increases dramatically to the higher values. The verizon.net speed test for the router on my gigabit plan was fairly consistent at 948d and 931u. Is there a way to get the higher WiFi throughput while not connected to a charger?
Which router are you using btw ?
90 Mbs down seems like single stream N, on 2.4Ghz
400 Mbs down is single stream AC at 5Ghz
Can you check what your link speed says in the wifi props on the phone
the single sim V20 is dual stream so you'd expect a doubling of that speed, should be able to do 800Mbs on AC and 180 Mbs on N at 2.4ghz with a dual stream router which most are these days.
The dual sim V20 is unfortunately single stream so my max speeds are 90 & 400Mbs instead of being twice as much
I don't understand why you get a difference in speed in the first place. Should not matter plugged or not
I'm using the Vz provided G1100 gateway router. Link speed on the phone says 866 Mbps. I'm at a loss too - probably a phone hardware problem. BTW, I'm still on US99610d deodexed ROM with Xposed and other mods that I wouldn't THINK would cause the problem, but....

Bolded bit implies your connection is good. Dual AC which i was expecting.
It's possible LG ramp down speeds to conserve battery. Not an issue with general use only with downloading
Bolded bit? Sorry, but I don't know what bit you are talking about. I remember seeing nothing bolded in anything wifi (settings). My router lists my V20 connection as "802.11ac" and I see nothing indicating any problem. But the phone still has the problem. I'm wondering if there could be an antenna problem and the charger conection acts as an extra antenna? Obviously l'm groping in the dark now.
