@ARGamingPK1 Hi again!

Yes, I tried today in the morning, this is what happened:

- I login using the Web UI to try to upgrade, I though it was kind of automatic but you need to download the firmware file previously

- Looked at the bottom of the deco M4R for version: US 1.0

- Searched in the tplink web for the 1.8 firmware for Deco M4R, found: Deco M4(EU)_V1_1.8.1 Build 20250829 (here https://www.tp-link.com/en/support/download/deco-m4/v1/#Firmware)

- I realized that 1.8 is for EU version ... but I have US version.

- Searched again in the tplink web for firmware updates for Deco M4R but US, and found out the latest is the one that I already have: Deco M4(US)_V1_1.7.0 Build 20250228Link (here https://www.tp-link.com/us/support/download/deco-m4/v1/#Firmware)

So, at this point I think I already have the latest version ... Otherwise I will have to update my US version with the EU version, but I'm not sure if it's correct, I'm scared to screw the device ...

Then I decided: ok, I'm to open a new thread to ask suggestions about this but my account was blocked because somehow I was updating post/messages to fast and the site thought I was spamming .... So until now (I guess) I was no able to reply or create new posts ...

Bottom line:

- I think I already have the latest version

- version 1.8 is for a different version (EU)

Again thanks for replying!

ps: tried to make a backup using a 5G connection but I got the same error :(
