Model: Deco X90  
Hardware Version: V1
Firmware Version: 1.1.0 Build 20210526 Rel. 50360

Model: Deco X90

Firmware: 1.1.0 Build 20210526 Rel. 50360

ISP Speed: 500 Mbps download, 100 Mpbs upload

 

 

I having 2 issue:

1> Speed Capped at 100 Mbps under router mode

2> Speed Capped at 100 Mbps under AP mode after perform "Network Optimization"

 

Issue 1:

My ISP provide 500 Mbps download and 100 Mbps upload. With original router given, no problem to reach the maximum speed.

Just received the X90 unit yesterday, trying to setup as "Router" mode with setup below:

 

Broadband modem ==> Deco X90 (main) ==> Deco X90 slave

 

Before I setup the slave unit, I test the speed with main unit, it capped at 93+ Mbps, both upload and download. Either using ethernet (CAT 6) or WiFi, from laptop or my iPhone 12 Pro Max (Wifi 6).

 

Troubleshoot:

1> Set Vlan either with preset ISP setting or custom correctly

2> Turn off UPNP

3> Turn on QoS and set the limit to 1000 Mbps

4> Turn off QoS

 

All above not working, speed still capped at 93+ Mbps.

I change to "Access Point" mode by the setup below:

 

Broadband modem ==> Original Roter ==> Deco X90 (main) ==> Deco X90 slave

 

The speed limit problem has been resolved. My speed jump to 510+ Mbps download with 110 Mbps upload (at main unit).

I cannot run at AP mode as I want to take out my original router and link the Deco X90 to a switch TL-SG108E. I need this issue to be resolve.

 

Issue 2:

So I try to run under AP mode, when perform "Network Optimization" with Deco Apps, the speed drop to under 100 Mbps immediately after this process. I have to turn off the power and restart the unit (pull the power cable out and reconnect), it back to full speed (under AP mode). This is not a criticle issue as long as I control my figure don't touch that button in the Apps.

 

Deco X90 is the highest range product, which very costly price, I really expect a seamless experience but look like I paying more to get in to trouble? Hope this can resolve fast.

@TP-Link 

 

Thanks for your support:

 

 

1. Under the access point mode, after running the network optimization, would Ethernet devices dropped to 100m/s as well?

No, Ethernet still able to get full speed, only WiFi drop and capped at 100Mpbs. 

 

 

2. Under the router mode, could you please help me check the Ethernet link speed on the Ethernet laptop when connected directly to the main Deco X90.

It shown 1Gbps, as attached.

@HEWHH 

 

Hi bro, have had the same issue.

 

Now have been solved, the engineers have made a firmware upgrade, but not sure if its available to public... as he installed it manually during our remote session.

 

It's the firmware 1.1.1 Build 20210715 Rel 71438. if its available, you should update it and it should solve your issue.

 

But now, there is another issue which is the satelite unit, the 3rd 5mhz band got disabled on this satelite deco x90 unit... Im currently liasing with their senior engineer on this as well....so, hopefully can solve this issue soon too.

 

Just helping out!
