I have LG H820 that I can run on average 8 mbps on network with full bars on LTE. In same spot when I hook up wired mirroring from USB-C to HDMI to tv my data goes down to 1 to 2 mbps on network with one to two bars on LTE. As soon as I disconnect USB-C my network jumps to full bars and speed is back up. This use to not happen. How does the phone tell the network that its mirroring? How can I stop the phone from telling the network its mirroring?
I can run 3g at 3 to 4 mbps, mirroring or not, which I have been doing as a work around but the upload speed is so slow. My upload speed on LTE doesn't change if I am wired mirroring or not. I am mirroring with a Cable Matters USB C to HDMI Adapter if that is relevant. I am not throttled during these times. Thanks.

Guys,
I have an Active but its probably the same for the regular S4.
I was just transferring a bunch of music files to my phone wirelessly and I was shocked how slow it was.
I just got under 2MB/s on a 72mbit link with WPA2 AES encryption.
I had full bars connecting to a Asus AC66U router.
I thought AC wifi is capable of almost gigabit speeds.
How do I see if my phone is using N or AC? Is there a way to force an AC connection.
Anyone else have the Asus AC router?
Can you post your speeds.
Thanks
Oli
Ok, figured it out. It was connecting on the 2.4 GHz, had to get it on the 5 GHz. Now getting 433Mbit connection
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 bought myself a MHL cable to hook my Note 4 up to my TV. All works great until I start using Youtube. As soon as I start playing a video, I lose network coverage and it will only return when I disconnect the MHL cable.
Is it possible that my network operator (Hutchinson 3 - Three UK) is able to determine when I am using MHL and block Youtube? I know they can tell when I am tethering as they also do the same thing and I lose network coverage. Seems a bit annoying! My home broadband is terrible (around 1-2mbps at best) so WiFi is out of the question; I was hoping I could start watching Youtube on my TV as my phone signal is brilliant and I have an unlimited data plan.
Just got the new shield tv box and my wifi speeds are incredibly slow. Get 100 mbps on all my other devices, but 5 mbps.
Anyone know of a solution?
i have exactly the same problem on 2.4ghz wifi. i even put the router right next to the shield tv. still only 6-10mbit (max. 15mbit) while i have a 100mbit connection from my provider. on the 5ghz wifi i get about 60mbits but on both i have huuuuuuuuge packet loss every 3-7s. makes gamestream impossible :/
i even bought a new router. tried with my standard fritzbox 7390 and now with a new linksys wrt1200ac. results are the same slow and bad connections to shield. everything else (i.e. notebook, smartphone, pc) works just fine...
Unplug any peripherals connected via usb and try again. This means wireless mouse, usb hub, etc.
I've found the only way to get consistent speeds with the shields wifi is to use a usb hub that has it's own power source.
Can confirm. Having an extremely hard time streaming anything in 4K on Netflix. 350 mbps Download and 30 mbps Upload. Netflix network speed test shows like 29 mbps... I installed a browser and went to Fast.com and get about 80 mbps. Downloaded the "Fast" app on my Pixel XL and immediately got 250 mbps down standing in the same room connected to the same 5 GHz Wireless-AC network. Amazon Prime eventually decides to stream in UHD and HDR, but it takes a while. Youtube, oddly enough, streams in 4K almost immediately.
Router is an ASUS RT-AC1900P.
I'm still having issues. Has anyone solved this problem?
There was an update recently and the performance in Plex seemed to get a little better, but high quality videos still stop and buffer.
Are there any debug tools on the shield that could be used?
Ok so I had terrible performance on 2.4ghz. on 5 GHz it only connected once so decided to have a look at my modem settings and tweaked it.
Have it set to
802.11a/n/ac mixed
Channel auto channel 112
20/40/80 MHz
Everything working smoothly now with no dropouts
I'm having the exact same issue with my new 2017 Shield. If I restart the Shield, it will occasionally work at full speed on 2.4 OR 5 Ghz. But most of the time, it's under 10 mbps - transferring from the internet OR from my PC that is hardwired to my router. I already had an RMA done, and I'm having the same issue with the new Shield NVIDIA sent me. I've tried every channel possible, used tools to find the proper channel, etc. Same slow speed. None of my other devices have the same issue, even in the same location. Nothing is attached via USB.
What's the deal? Any solutions?
Having problems as well. I have my wirless router I'm a good distance running 350mbs and I can pass the test for the games. When I try to play the games they instantly show I'm having wifi problems.
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.
