Hello colleagues.
Briefly the issue. I’m bought phone Xiaomi Redmi note 2 prime. And at all available to me Mikrotik devices phone can’t be connect faster than 54Mbps to TX data https://www.dropbox.com/s/lbqo7asxu6rixew/Выделение_314.png?dl=0
Tested on RB 951G-2Hud, hap lite old and new one version (RB941-2nD и RB941-2nD-TS) is the same behavior.
Your colleagues from support who been on the MUM in Ukraine 8 Dec 2015 have not been able to resolve the issue but recognized problem. They said contact on the support.
The problem is also present in other owners of phones of this brand, as can be seen from the frequent posts 4pda and other sites, for example http://en.miui.com/thread-35456-1-1.html
When testing with other routers ASUS (DD-WRT) and the tp-link (default FW) allowed in both directions for 40 megabits and 65 respectively. Tested downloading and uploading to an ftp server in a local Gigabit network.
As tested on Zyxel Keenetik (diff verions)also no problem.
Changing the parameters of the wireless router to give nothing except further deterioration rate.
Good afternoon!
Sorry for my english.
For a long time I use MikroTik RB2011UiAS-2HnD, RB951Ui-2HnD, RB751G-2HnD and RB941-2nD. ROS v6.38.5 and v6.39rc72.
Recently purchased a phone Lenovo P2.
I can not understand why Lenovo P2 connects to WiFi at channel speed Tx Rate: 54Mbps, Rx Rate: 150Mbps-40MHz/1S/SGI? That is, the Tx Rate is only 802.11g, and the Rx Rate is 802.11n
Accordingly, the reception speed does not exceed 20 Mbit.
I tried every possible WiFi settings - from reset, to experiments with different parameters in the advanced mode. I tried to play with channels, and with the width of channels, and with the power of the transmitter, etc. Still, more than 54Mbps at the reception there.
And the same phone Lenovo P2 with routers D-Link, TP-Link, Asus, etc. Works fine, at a speed of ~ 60-70 Mbit in both directions.
What could be the reason? Is this some known problem? And will it be eliminated?
I have a similiar problem, but with Letv x500 smartphone and two tablets Asus ME400C and Chuwi Hi8. Tx Rate only 54Mbps, Rx Rate - 75Mbps-20MHz. Also tried different wifi settings, different router locations, no result(( Technical support couldn’t help me to fix this problem.
The same here: hAP lite (RB941-2nD), latest firmware and RouterOS, 802.11n, Xiaomi Redmi 4 Pro. Other devices (iPad 2, iPhone, some notebooks) get expected rates (up to 60Mbps downlink). Only Redmi 4 is stuck at 801.11g rates, never getting speeds over 20Mbps when working with Mikrotik.
Had anyone some success contacting Mikrotik on the issue? What can we do to resolve this incompatibility?
I have the same problem. I have done several tests with different smartphones in map lite, wap and groove. I have tried changing the settings several times but I get the same results.
My smartphone shows only 54 mb in reception and however shows 72 mb in transmission.
RB951Ui-2HnD
Hello, there is always the same (well known) bug with TX Rate on all smartphones with android. TX Rate is always only 54Mbps but RX Rate is 72.2Mbps-20MHz/1S/SGI.
I have the solution on Linux machines (Linux Mint and Ubuntu) but not for unrooted phones.
For some wireless chipsets a simple tweak is sufficient for increasing the connection quality a lot.
Namely disabling the power management for the wireless chipset.
The speed of your wireless internet may then increase also.
Now, You can do that as follows:
Launch a terminal window.
Type in the terminal (or copy/paste):
Now a text file opens. In that text file, you see the following content:
[connection]
wifi.powersave = 3
Change 3 into 2.
Save the modified file and close it.
Reboot your computer.
