Deco M4R Ver 2.0 - Firmware 1.7.0 causes WAN issues, rollback required
Hello!
I have a TP-Link Deco M4R(EU) Ver: 2.0. Firmware: 1.7.0 Build 20250228 Rel. 64570.
After updating the firmware, the Internet from the Beeline provider (Kazakhstan, L2TP connection) stopped working.
Wi-Fi is distributed, devices are connected, but there is no access to the Internet. The application displays the message "non-standard speed on the WAN port".
On the previous firmware, everything worked stably. The problems began immediately after the update
How can I roll back?
Hi, welcome to the community.
Can I have a screenshot of the error "non-standard speed on the WAN port"?
Did Deco M4 turn to solid red?
The " L2TP connection' here, do you mean the internet connection was set to "L2TP", right?
If you'd like to spend a little more time, I could forward your case to the senior engineer for further assistance, and you can send an email to support.forum@tp-link.com with a copy of the web UI system log.
However, if you need an urgent solution, please refer to this link:
