@Joseph-TP @Sunshine  I am writing this to express my deep dissatisfaction with the current state of the Archer BE230 v1.20 and the lack of a professional solution regarding the 1.2.5 firmware issues.

The stability issues with MLO and IPv6 are well-documented in this community (Threads #862218 and #862230). It is clear that this is a widespread software regression and not an isolated configuration error. Since the update, my network has become unreliable, defeating the purpose of upgrading to a Wi-Fi 7 system.

Furthermore, the suggestion to downgrade to firmware 1.2.1 is completely unacceptable. We are talking about software that is 9 months old. Asking users to revert to a nearly year-old version means:

1. Losing critical security patches released in the last several months.

2. Sacrificing performance optimizations: Previous versions suffered from significant Wi-Fi slowness, an issue that had been gradually improving with recent updates. Downgrading would force me back to those poor speeds and poor performance.

3. Accepting a broken product instead of receiving the modern support we paid for.

I did not purchase a flagship Wi-Fi 7 router to run outdated, slow software just because your engineering team failed to stabilize the current build.

I am requesting the following:

• An immediate Beta firmware that addresses the 1.2.5 instability issues without forcing us back to the 'stone age' of version 1.2.1.

• A transparent timeline for the next official stable release.

• An escalation of this case to the senior engineering team.

If TP-Link cannot provide a functional, up-to-date firmware for this hardware revision, I will have no choice but to pursue a full refund through consumer protection authorities, as the product fails to meet its advertised specifications.
