XE75 Pro Download Performance Issues

XE75 Pro Download Performance Issues
XE75 Pro Download Performance Issues
Monday
Model: Deco XE75 Pro  
Hardware Version: V1
Firmware Version: 1.2.14 Build 20241223 Rel. 16551

Problem:
On speed tests from a hardwired PC, my download speed is consistently significantly lower than my upload speed. The download is usually around 1.2 Gbps, while the upload speed is between 1.7 and 2 Gbps. Speed tests on mobile devices over Wi-Fi show similar results, where the download speeds are significantly lower than the upload speeds. 

Background:
I have symmetrical 2 Gbps download/upload service from my ISP. I am using two Deco XE75 Pro nodes. One node is on the main level of the home and is connected to the modem with a Cat 7 cable. The second node is on the second floor in my office. There are no QoS settings enabled, no known interference, and no heavy bandwidth usage during testing. I am currently unable to test speeds directly from the modem.

Speed tests from my PC are done while hardwired to the node on the second floor. Speed tests on a mobile device are done over Wi-Fi while connected directly to the main node on the first floor, standing next to it.

Question:
Does anyone have any suggestions on why my download speeds would consistently be significantly lower than my upload speeds on both wired and wireless tests?

1st place I would start is with your firmware it is out of date if your deco is hardware version 1. To check for firmware updates do the following 

 

1. Go to http://tplinkdeco.net/ and sign in - use the same password you use to log into the deco app

2. Once your logged in click on Advanced

3, Click on System from the menu on the left 

4, Now click on Firmware Upgrade

5. Scroll down to the bottom of the page and click on Check for upgrades

 

Install the firmware it finds then try the speed test again. Let us know if it fixes the issue or not

I have updated the firmware here is a screenshot of that. I will test the speeds when I get home. I only selected the hardware version 1 because I thought it was a required field. I am unsure which hardware version my system is.

You can find your hardware version on the bottom of the deco :)

Any idea what network card your using? It "could" be the speed limit of the card. Could also be a cable issue. Also try this steps in this FAQ and see if they help.

I am having similar issues, but worse. I have been on a fiber connection for about 2 months now and just a couple days ago I noticed a significant drop in my hardwired PC's download performance. I speed tested it and I am getting terribly slow speeds

958f79fc696345f699806cfca584885e

 

It is a 1.1 gb speed. Previously my speeds were typically tested like this

I am updated to the most recent firmware version. Nothing has changed (same ethernet cables, same position in the house) and speed test directly into pc bypassing router provides similar speeds as I previously received

I don't believe the network card would limit strictly the download speed as the upload speed represents the actual isp speed.

 

The issue is also on my mobile device just slightly slower speeds logically because it's wireless not wired.

Re:XE75 Pro Download Performance Issues
Thursday

  @HelpFixDecoApp I was able to find a solution with my fiber ISP. Apparently there is a known issue with TP Link (Specifically the Deco models) and fiber. TP Link devices prefer a Public Facing IP address over our Carrier Grade NAT. Once they made that switch on the back end my hardwired PCs returned to normal download speeds and my smart devices could finally interact with my router again.

Glad you got it working 

 

@Ryan 

 

Anyway to add this as an option on all decos going foward? Then the customer can change the option themselfs if need be?
