Model: Deco PX50  
Hardware Version: V1
Firmware Version: 1.2.2 Build 20231226 Rel. 74361

I have Symetric 500Mbps Internet speed and, in the main Deco, I could have decent speed up to 450Mbps using Wi-Fi, which is very good.  Then, my ISP proposed me to duplicate it. I am currently on trial mode until tomorrow and the best speed I could get is 612Mbps.  Using Ethernet from either the ISP modem and from the Main Deco is ok, since I got speeds up to 985Mbps. 

 

  • QoS is off and the top speed settings are both in 1000Mbps.
  • Firmware version (v1) is 1.2.2 Build 20231226 Rel. 74361
  • Latency is 1ms 
  • For the other secondary three Decos, the speed is the same as with the symetric 500 (158Mbps, 174Mbps top)
  • 2048 is Wi-Fi (advertised) the top speed from Decos PX50

 

For what I can say, I am only adding more digits to my montlhy payment. Is there any missing parameter that I am not aware of that is preventing this? I read several threads about the Internet speed and the link speed and I got confused.  For a normal user, if a product states that you can have speed up to 2048, the user is buying it because it has a subscriptions with the ISP that supports this.

 

Thanks for yor help.

  @EAMT I found a similar topic raised by @John_Greaves , the 597844 that can be found here:  https://community.tp-link.com/en/home/forum/topic/597844 .  I have Deco PX50 and the problem persists.  Any migration to a Wi-Fi7 TP-Link solution is on hold, since I do not want to spend more money and then found out umpleasant surprises.  Those speeds listed below seem not reachable at all.

  @EAMT 

Hi

 

The connection between the satellite Decos and the main Deco plays a big role in the speed of the satellite Decos. To boost the speed, consider setting up an Ethernet Backhaul or Powerline Backhaul using Ethernet cables or powerline between the satellite Decos and the main Deco.

For a quick test, it is suggested that you place the satellite Decos and main Decos in the same room. You could also try switching to 5G only in the Deco App > more > Wi-Fi settings and test the 5G speed.

 

Thanks a lot for your cooperation.

Best regards.

  @Joseph-TP Thank you.  I already did.  I got no more than 612Mbps.  People looking for products in Amazon looks only that the equipment is capable of reaching 2402 Mbps.  So, if the ISP is offering 1000Mbps, they will get that speed using these products.  No.  They equipment will only handle up to 650Mbps in a very controlled testing environment.  It will not matter that you have a 3000 or 5000Mbps link.  So you are provided with explanations about data link and internet speed and a lot of explanations (and excuses) that are not explicit in the ad. 

 

Testing results:

612Mbps top speed reached in my testing environmnet.  Link data rate is up to 2402Mbps on Deco PX50.  25.48% of the speed delivered.  The rest is...

 

My learning experience is to ask the ISP for a capable product to handle the speed they are offering and explain clearly what to expect.

  @EAMT 

Hi, Thanks for the further update.

Have you checked the wireless link speed on the mobile devices when its download speed is 612-650m/s? Can I have the model number of the tested mobile device?

How to check the associated/link speed on a wireless client

 

The Deco PX50 achieves a speed of 2402Mbps over 5GHz based on the highlighted factors in the attached picture, which is not just for TP-Link routers and it suits other brands as well. In the lab test, when the mobile device connects to Deco PX50 with a link speed of 2402Mbps, the expected wireless download speed is about 900-1.2Gbps. So I think it is very likely your tested device doesn't support 160mhz over 5Ghz and the maximum link speed is about 1201Mbps so the final Wi-Fi download speed would be about 600-900Mbps.

 

However, as you pointed out, they are explanations and are not explicit in the ad. However, it might help to understand the commonly used network parameters for future decisions. Thank you very much and best regards.

  @David-TP The equipment for the test is an iPhone 15 Pro Max.  Technical specifications: https://support.apple.com/en-us/111828.

  @David-TP Another test.  Look at the speed of 2.4Gbps.  The max

Sorry, Dell Lattitude 7410. But iPhone 15 Pro Max should handle tthis. With 500 Symmetric, I got 452Mbps. Upgrading to 1000, I only got 612Mbps. The proportion is not similar.

  @David-TP By analyzing your insights, I got this information from Apple:  https://support.apple.com/guide/deployment/wi-fi-specifications-for-apple-devices-dep268652e6c/web

 

I don't know if this table is complete or not, but it seems that the iPhone 15 Pro uses the 160MHz bandwidth only at 6GHz, something the Deco PX50 can't do. However, using the 80Mhz, the iPhone 15 Pro can reach up to 1200Mbps.

 

I will appreciate if you could get more information about this and many thanks for your support.
