I have serious problems with our Deco X10 system since the latest firmware upgrade to 1.3.0....  

My system ran without error for months before this upgrade. I cannot only deduce that others are having the same problem? The machine is suddenly not fit for purpose since the upgrade. In Australia, the Australian Consumer Law requires that products be fit for purpose and of acceptable quality. A firmware update that renders a product unusable is arguably a breach of that guarantee. 

If they cannot fix it quickly, could they help me downgrade to v1.2.0 which DID work?
Am I alone in this issue?

here is the letter I wrote to support...

Dear TP-Link Support,
I am writing to report a serious and ongoing service failure affecting my TP-Link Deco X10 mesh system caused by firmware version 1.3.0 (build 20250725), which was applied via automatic update.
I want to be clear that this is not a minor inconvenience. Since the update, our household has no reliable internet access. The system drops connectivity every 5–15 minutes, with each outage lasting 1–2 minutes. This has been continuous for several days. Our email service is only intermittently available as a direct result, and normal use of the internet is impossible. The system is effectively unusable.
The upstream router is functioning normally throughout these events, confirming the fault lies entirely within the Deco firmware.
I have reviewed the system logs in detail and identified the technical root cause:
    1.    ‘rtk_get_vap_status: cfg80211 return -19’ — appearing every 30 seconds throughout operation. This ENODEV error indicates the wireless driver introduced in this firmware build is repeatedly failing to locate its own virtual access point interfaces.
    2.    The ‘nrd’ roaming daemon is crashing and reinitialising continuously, each time failing to load required AI roaming threshold files. Each crash causes a connectivity dropout.
    3.    Multiple syntax errors were logged in startup scripts at first boot of this firmware version, indicating the firmware package itself was not cleanly compiled.
    4.    Repeated configuration lookup failures for ‘plc_sync’ and missing ‘eth0’ interface references not present under the previous firmware.
This system ran stably and without issue for over 12 months prior to this firmware update. TP-Link’s automatic update mechanism applied this defective firmware without my explicit consent, rendering the system unusable.
Given the nature of these errors, I believe other Deco X10 customers will be experiencing identical issues and may not yet have identified the firmware as the cause. I am urging TP-Link to treat this as a priority issue affecting multiple customers.
I am requesting:
    1.    An urgent response acknowledging this fault
    2.    Immediate access to the previous stable firmware version to allow rollback
    3.    A committed timeline for a patched firmware release
    4.    Confirmation that the automatic update mechanism will not re-apply this defective firmware
I have the full system log and have already sent it directly. The log clearly shows the repeating crash cycle and startup errors.
Device details:
    ∙    Model: Deco X10(US) Ver:1.0
    ∙    Firmware version: 1.3.0 (build 20250725)
    ∙    Network mode: Access Point (connected to a separate fibre router)
    ∙    Log date: 10 March 2026
I expect a prompt response given the severity of this issue...
