Hi,

TP-Link's firmware upgrade mechanism only cares about the version number. The build date of the firmware is irrelevant.

Basically, what the note "This upgrade is irreversible and downgrade is not supported" means is that after upgrading to firmware version 1.3.1 it is not possible install a firmware with a version number lower than 1.3.1 via the regular web interface.

Yes, actual 1.1.3 fw falsely named and released as 1.3.1, i think.

Yes, when the system is in the firmware Archer BE230(EU)_V2_1.3.1 Build 20260106 it does not allow to upgrade to the newest version available. Firmware Archer BE230(EU)_V2_1.1.6 Build 20260316 must be installed in Rescue Mode (https://www.tp-link.com/us/support/faq/1482/ use the AX mode), and it will upgrade to 1.1.7 after that. But don't activate after the 1.1.7 the auto-upgrade function, as this will upgrade the router again to the 1.3.1 firmware and it will redo all the good changes introduced in latest builds!!

Hi,

I am interested to know whether the "Link Aggregation" feature introduced in firmware version 1.3.1 is also present in version 1.1.7 (or 1.1.6). Could you maybe check this for me? If that option exists, then it should be located in the "Advanced" -> "Network" -> "LAN" menu. Thanks.
