DIR-895 Poor Wifi Performance

<< < (2/4) > >>

FurryNutz:
"I understand that the wireless will never be as fast as wired even tho they are claiming:
"Simultaneous Tri-Band: Deliver faster Wi-Fi speeds of up to 5332Mpbs (1000Mbps + 2166Mbps + 2166Mbps)"  http://us.dlink.com/products/connect/ac5300-ultra-wi-fi-router/" Be aware that the wifi speeds mentioned are connection rates between the router and devices, not actual data stream speeds.

If you think there is a bad performance between FW versions, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. Notify them of your experiences and definitely reference this forum thread. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Hey,

Overall the performance is pretty good and I'm happy with it.

FurryNutz:
Awesome, glad it's working better for you.

What version of FW was this tested on?

Request for you, would you make a post on how to set up iPerf3 and where to get it? I'd like to make a FAQ for users here in the forums who'd like to test there router performances. Care to make a post and give full details on what you do to set it up and run it?

Hi FurryNutz,

I'm currently on Firmware Version 1.00.B11 ( I may upgrade and try version 1.02 next weekend if I'm bored)

https://iperf.fr

IPerf which is a freeware application that can run under a variety of operating systems such as Windows, MAC OS and Linux. The application requires two machines where one acts as a listening Server and one as a sending Client. ( I'm using a Macbook pro and a Synology NAS ).

IPerf generates traffic from the Client side towards the Server side and the results are displayed on how much traffic we were able to send under a specific time window and what throughput was achieved.

You might be curious to choose another application like FTP or Windows file sharing, however, there is an important detail to highlight here, FTP/SMB relies on the disk read/write speeds, Iperf does not since it is traffic handling on the NIC itself. So in case you are having some really old IDE type Hard Drive on your Server side results will be affected in a negative way. Windows file sharing also can have varying speeds depending on Microsoft proprietary file transfer protocol which lower down the speeds in certain cases. So the bottom line for this is to use IPerf for throughput testing, if you want to test write speed over the network they've added a feature in the latest version to do so.


* Download the executables for both machines ( Client and Server ) https://iperf.fr/iperf-download.php
* Decide which machine is the server and which is the client
* Run the commands below in "quotes" ( Do not type the quotes) 
* Machine1 ( Server ) :  "/usr/local/bin/iperf3 -s"   The server machine is now listening for iperf connections
* Machine2 ( Client ) :  "/usr/local/bin/iperf3 -c xxx.xxx.xxx.xxx -t 5"  replace xxx. with the ip address of your server machine. This will test the throughput for 5 seconds.
You should see results similar to this

On the server when you start listening you should see something like so:
MacBook-Pro:iperf$  /usr/local/bin/iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------

On the client machine, you should see something like so: ( Note the -T argument lets you give the test a name)

There's a really good write up on iperf here: https://www.es.net/assets/Uploads/201007-JTIperf.pdf
There seems to be a windows GUI versions here http://www.iperfwindows.com
https://www.perfsonar.net/media/cms_page_media/3407/1.1-TCP-Labs.pdf

I'm sorry it's not a very detailed guide, however, hopefully this information is useful and will help some people debug network errors as speedtest.net is not the best way.

Wes

FurryNutz:
Awesome info, any chance of posting details for the GUI version as well? Would be good for both formats. If you can and have time too.

Thank you again for this. Will pull this post out when it's final and make it a FAQ.  ;)
