Try to get the devices you are having issues with to connect and then do the following below. 

 

First please access the Deco web UI by entering "tplinkdeco.net" in your browser. Navigate to Advanced > System > System Log, select "ALL" in the log type, and save the file to your local computer. Then follow the steps below making sure to attach the logs to the email.

 

I recommend sending an email to forumsupport.usa@tp-link.com with the following information:

Hi, thank you very much for your feedback.

For the speed issue on the Samsung devices(<0mbps), it is recommended to test the new beta firmware here:

Wait for your reply.

Best regards.

Hi, can I have the model numbers of the mobile devices that can't authenticate when connecting to Deco WiFi?

For the laptops with Intel AC 8265, it connects and ping gets through, but no internet, which I think might be similar to the "close to 0 Mbps bandwidth" issue on the Samsung devices when connecting to Deco.

If possible, it is also recommended to test the new beta firmware here:https://community.tp-link.com/en/home/forum/topic/856648

 

Wait for your reply.

Best regards.

Hi
Just tried to update with the new release but I get "Upgrade failed. Please select the latest version of firmware to upgrade."
I'm now trying to upgrade from ver. 1.3.1 Build 20251023 Rel. 43624.
All the best,
A. 
 

Edit: double checked. Installing ver. XE75Pro_XE70Pro-SP1-up-ver1-4-999-P1[20260319-rel38541]_2026-03-19_10.43.56.bin from ver. 1.3.1 Build 20251023 Rel. 4362 returns me that error.

I'm also getting an error message when trying to upload/install the firmware: "Upgrade failed. Please select the latest version of firmware to upgrade."

 

Edit: NVM. I accidentally was trying to upgrade to an older firmware. Currently updating to the newer firmware. 👍

Is your XE75 V2 the Pro or non-Pro model? If it's just the XE75 V2, then you'll want to use the first download link in the original post: 

 

Deco XE75/XE5300/WE10800_V2/V3 1.4.999_Build_20260319_rel_57690_Beta (updated 2026.3.19)

 

EDIT: Updated download link to reflect the latest build in the original post.

I'll provide an update later. The person with the Samsung device (Galaxy A17 5G), is currently out and will be home later.

 

I did notice new settings appear on the Deco app after updating the firmware (Wireless Network Mode for 2.4GHz band).
