Setting hotspot transmit rates - Atrix 4G General

Anyone know if we can set the connection rates on the Atrix in Hotspot mode?
I noticed that its set at 54g rates when i connect to it, and while I understand that is even faster than the actual theoretical rate you can achieve with the 4 G anyway, was just curious if its possible to change the rates.

ATT HTC Pure ICS (tethering) speed slower than phone

Hi
The tethering speed on my computer is much slower than the actual speed on my phone. I tried both ICS and WMwifirouter via usb to tether. And they both show similar speed. So i don't think it's because of software.
0.5m kbs on computer vs 1.7m kbs on phone
do you guys know a solution for this?
before i used Samsung a777 to tether and the dl speed was 1200kbs
so i don't know if ATT now block smartphones form tethering?
Make sure in Settings/Connections/Connections you have set both networks to MediaNet and take out any proxy settings.
Not sure why it would be slower though.
I tether and the speed is the same without any tweaks.

How to gain maximum bandwidth from your ISP

I created this topic to get idea about how to utilize the allotted bandwidth.
Point reasons which could lower your data rate or bandwidth.
In this thread it would be possible to get technical thoughts of members. :thumbup:

According to me in wired broadband your SNR should be high enough , so that you never get frequent disconnections, Have no experience about the wireless connection , i'll keep eye on this thread to get idea about the best utilization of network.
@jitkr, once i searched and found that on windows operating system we can disable the reserved bandwidth of system to gain maximum data rate from Distributer.
use wired connection instead of wireless, definitely it'll save lots of bandwidth :laugh:

Is it possible to supply power at user end to receive strong signal.
I think this can lower the noises in signal.

It depends on the kind of connection you got. Usually a wired signal will give more bandwidth than wireless considering a wired signal can give you a Gigabit from your router to your computer if you get the right kind. Wireless N however should give you decent bandwidth if you have a slow enough connection (like mine is Cox 25Mb/s down cable, so it's perfect). The biggest things are making sure you have a good router to begin with if you have wireless (I don't have N but I use a WRT54G on dd-wrt and it's pretty fast). Other then that, make sure you have good line quality from your modem to the ISP. If you have a lot of noise, you can get a lot of disconnects and such.
A few other things: disable TCP automatic tuning if you have a Windows higher than XP. If you can manually do it, increase your TCP window size to a higher level. At work when we tell people to increase speeds of Windows file transfers to the servers we sell, we have them try a TCP window size of like 500kB and it seems to help. Disable ipv6 completely from your pc and router.

Slow WIFI Transfer

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

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

WiFi Speed Dependent on CHarging Status

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.

Speed up phone's WiFi? Speedtest shows slower than actual internet speed

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..
