Main changes between OpenWrt 25.12.1 and OpenWrt 25.12.2

Only the main changes are listed below. See the full changelog for details.

Device support

• airoha: rename kernel module kmod-pwm-an7581 to kmod-pwm-airoha — users with this module explicitly installed need to reinstall under the new name
• apm821xx: fix U-Boot environment definitions for NETGEAR WNDR4700, Western Digital MyBookLive, Meraki MR24 and Meraki MX60; fix PCIe boot failure on Meraki MX60
• ath79: fix initramfs boot for Huawei AP5030DN and AP6010DN
• ath79: fix VLAN CPU port tagging on 2-CPU-port devices (affects several dual-CPU switch configurations)
• ath79: remove incorrectly included WiFi packages from Mikrotik RB750r2 (device has no WiFi hardware)
• ipq40xx: fix ART partition name for Linksys Velop WHW03 V1 — restores correct WiFi calibration data access
• ipq40xx: fix MAC address reading for Linksys devices using eMMC-based NVMEM
• lantiq: xrx200: fix failsafe mode on BT HomeHub 5A — LAN ports 1 & 2 now work correctly in failsafe (https://github.com/openwrt/openwrt/issues/22480)
• mediatek: Bananapi BPI-R4: fix SFP+ electric module support — modules that stopped working after a snapshot upgrade are now functional again (https://github.com/openwrt/openwrt/issues/19878)
• ramips: fix kernel decompress error that bricked ELECOM WRC-X1800GS on 25.12.0 (https://github.com/openwrt/openwrt/issues/22270)
• ramips: fix initramfs kernel load address for TP-Link EAP615-Wall v1
• ramips: fix MAC address assignment for Xiaomi Mi AC2100
• realtek: fix D-Link fan control script

WiFi fixes and improvements

• wifi-scripts: fix 160 MHz channel width configuration — hostapd was not correctly configured for 160 MHz, preventing its use (https://github.com/openwrt/openwrt/issues/22481)
• wifi-scripts: fix SU beamformee antenna count — incorrect count was passed to the driver
• hostapd: fix memory leak in Radio Resource Management (RRM) ubus interface
• mac80211: ath12k: add thermal sensor support for QCA/IPQ devices
• mac80211: ath9k: fix GPIO mask handling from device tree
• mt76: fix severe WiFi latency regression (up to multiple seconds) on 2.4 GHz introduced in 25.12.1 — affected many MediaTek devices including OpenWrt One, Zyxel EX5601, ASUS RT-AX53U, Xiaomi AX3000T/AX6000, Cudy WR3000/X6, GL Flint 2 and others (https://github.com/openwrt/openwrt/issues/22491)
• mt76: multiple further stability fixes for MediaTek WiFi chipsets (MT7615/MT7915/MT7996/MT7992/MT792x):
  • add per-link beacon monitoring for MLO (Multi-Link Operation)
  • fix MT7996/MT7992 link handling during MLO station add/remove
  • fix scan work requeue race with spinlock

Upgrading to 25.12.2

Upgrading from 24.10 to 25.12 should be transparent on most devices, as most configuration data has either remained the same or will be translated correctly on first boot by the package init scripts. For upgrades within the OpenWrt 25.12 stable series, Attended Sysupgrade is also supported, which allows preserving the installed packages.

• Sysupgrade from 23.05 or earlier to 25.12 is not officially supported.

• Cron log level was fixed in busybox. system.@system[0].cronloglevel should be set to 7 for normal logging. 7 is the default now. If this option is not set, the default is used and no manual action is needed. https://github.com/openwrt/openwrt/commit/fc0c518a88e68d3deef04bec73b33d35186d6546

• Bananapi BPI-R4: Interface eth1 was renamed to sfp-lan or lan4, and interface eth2 was renamed to sfp-wan to match the labels. You have to upgrade without saving the configuration. https://github.com/openwrt/openwrt/commit/cd8dcfef378044a1687adfa3738f01f9a9622baf

• TP-Link RE355 v1, RE450 v1 and RE450 v2: The partition layout and block size changed in this release to fix configuration loss on sysupgrade. Users upgrading from OpenWrt 25.12.0 or earlier must use sysupgrade -F to force the upgrade. The image must not exceed 5.875 MB (6016 KiB).

• Meraki MX60: Direct sysupgrade to 25.12.2 is not possible without manual preparation — meraki_loadaddr must be changed before upgrading, as the default value is insufficient to boot OpenWrt 25.12+. See the device wiki page for instructions.

Known issues

• Zyxel EX5601-T0: the WAN interface was renamed from eth1 to wan — check and update your network configuration after upgrading.
• Pixel 10 phones have problems connecting to WPA3-protected WiFi 6 APs. https://github.com/openwrt/openwrt/issues/21486
• 802.11r Fast Transition (FT) causes connection problems with some WiFi clients when WPA3 is used. https://github.com/openwrt/openwrt/issues/22200
• SQM CAKE MQ (cake_mq): throughput may be unexpectedly low on some configurations after the scheduler fixes in this release. https://github.com/openwrt/openwrt/issues/22344
