  @Joseph-TP 

In my case, the problem remained, only now the internet disappears for 30 minutes.

Please return the ability to flash the previous firmware 

AX12(EU)_V1_1.1.24 Build 20240823

Because the Internet never disappeared there.

Ps. Your actions with degraded to the previous version, and their consequences encourage people to switch to Internet equipment from another manufacturer, which is a real shame.

Hello @Andrew_ua ,

Have you tried the beta firmware? Some users have tested this beta firmware, and feedback has been provided to fix unstable and unexpected behaviors.

 

I understand that the new firmware changes may cause some inconvenience. Generally speaking, if the latest firmware has a large gap, downgrading is not recommended to prevent errors during the downgrade process that may affect device performance.

 

Please believe that we are always committed to providing high-quality products and services. If you have any questions, please do not hesitate to contact us.

  @Joseph-TP why version 1.2.1 is not available in US version? Us version doesn't get any updates after 1.1.22 version.

  @Zeragon I just updated the beta fw: AX12V1-up-ver1-2-2-P1[20250904-rel63560]. Hopefully the problem is resolved. which previous firmware Ver = 1.2.1 Build 20250729 Rel. 73566, is very unstable in terms of download and upload connections.

  @Joseph-TP Your brand's quality is getting worse and worse, please immediately release the latest firmware that can downgrade to previous versions. your beta firmware feels very heavy when changing in the admin menu.

  @Poly_andro01 AX12 is generally more laggy than AX10, because previous one has single core while the later has triple core processor! I regret buying AX12, but was forced to choose it because AX10 is online product and I bought my router offline due to urgent need (as my previous TpLink Archer C6 also had frequent disconnect issue and it was confirmed by many other users in our group)

  @ჯოზეფ-TP I tried the beta version but it's still the same. When I run a speed test, the internet goes down for 10 minutes. The technician checked everything and said it's the router's fault. I bought a brand new router a week ago and I'm very disappointed.

Hello @georgex ,

 

Thanks for contacting our community.

 

Could you check if you have updated the firmware successfully? We received feedback from other users that this beta firmware can effectively fix network instability.

 

If the router Internet LED turns red/orange occasionally, please try the following troubleshooting steps:
    1) Connect a PC directly to your modem to verify if your ISP's Internet is stable.

    2) Ensure the Ethernet cable connecting your modem to the Router is properly connected, and replace old wires with new ones.
    3) Please change the DNS Server of the Router, log in to the web management interface of the Router, go to Advanced > Network > Internet > Advanced Settings, and change the two DNS Servers to 8.8.8.8 and 8.8.4.4,  How to Change the DNS servers on the wireless router and DSL modem router (New UI)?

Re:Losing connection on AX12, possibly from lastest firmware
Monday
Hello! Apologies, the email notification seems to have ended up in my spam folder. Since I updated, connection has been good. The printers didn't disconnect from the 2.4ghz band at all. Other than the beta watermark being annoying to look at, I have no complaints. The only thing to report is that today, at 03:50, the router seems to have encountered a problem starting up. I have scheduled restarts at 03:49, and logs produced led-controller errors. #################################################################### # Archer AX12 System Log # Time = 2026-02-16 20:34:01 # H-Ver = 1.0.0 ; S-Ver = 1.2.2 Build 20250904 Rel. 63560 # LAN: I = 10.0.0.2 ; M = 255.255.252.0 ; MAC = DC:62:79:96:25:50 # Clients connected: 2 ; WI-FI : 1 #################################################################### 2026-02-16 04:00:30 led-controller[1799]: <6> 288051 Start to run WAN1_ON 2026-02-16 04:00:30 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 04:00:30 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 04:00:30 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:59:09 led-controller[1799]: <6> 288051 Start to run WAN1_ON 2026-02-16 03:59:09 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 03:59:09 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:59:09 led-controller[1799]: <7> 288009 Failed to read LAN_OFF 2026-02-16 03:52:03 led-controller[1799]: <6> 288051 Start to run WAN1_ON 2026-02-16 03:52:03 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 03:52:03 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:52:03 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:48 upnp[9666]: <6> 217504 Service start 2026-02-16 03:51:47 upnp[9666]: <6> 217505 Service stop 2026-02-16 03:51:45 remote-management[9332]: <6> 282505 Service stop 2026-02-16 03:51:37 led-controller[1799]: <6> 288051 Start to run WAN1_ON 2026-02-16 03:51:37 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 03:51:36 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:51:36 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:32 led-controller[1799]: <6> 288051 Start to run WAN1_OFF 2026-02-16 03:51:32 led-controller[1799]: <6> 288051 Start to run WAN0_ON 2026-02-16 03:51:32 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:51:32 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:30 traffic-stats[6906]: <6> 269004 stats reset 2026-02-16 03:51:28 led-controller[1799]: <6> 288051 Start to run WAN1_OFF 2026-02-16 03:51:28 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 03:51:28 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:51:28 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:21 led-controller[1799]: <6> 288051 Start to run WAN1_ON 2026-02-16 03:51:21 led-controller[1799]: <6> 288051 Start to run WAN0_OFF 2026-02-16 03:51:21 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:51:21 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:10 led-controller[1799]: <6> 288051 Start to run WAN1_OFF 2026-02-16 03:51:10 led-controller[1799]: <6> 288051 Start to run WAN0_ON 2026-02-16 03:51:10 led-controller[1799]: <3> 288753 Config importing failed 2026-02-16 03:51:10 led-controller[1799]: <7> 288009 Failed to read LAN_ON 2026-02-16 03:51:10 traffic-stats[6906]: <6> 269003 stats off 2025-09-04 00:01:19 led-controller[1799]: <6> 288051 Start to run STATUS_ON 2025-09-04 00:01:18 led-controller[1799]: <6> 288051 Start to run GENERAL 2025-09-04 00:01:06 traffic-stats[6895]: <6> 269504 Service start 2025-09-04 00:00:53 factory-reset[6189]: <6> 284504 Service start 2025-09-04 00:00:33 parental-control[5217]: <6> 229504 Service start 2025-09-04 00:00:33 parental-control[5217]: <6> 229502 Function enabled 2025-09-04 00:00:30 firewall[4218]: <6> 209504 Service start 2025-09-04 00:00:21 led-controller[1799]: <6> 288051 Start to run WIFI2G_OFF 2025-09-04 00:00:21 led-controller[1799]: <6> 288051 Start to run WIFI5G_ON 2025-09-04 00:00:20 upnp[3793]: <6> 217504 Service start 2025-09-04 00:00:18 upnp[3793]: <6> 217505 Service stop 2025-09-04 00:00:14 remote-management[3040]: <6> 282505 Service stop 2025-09-04 00:00:00 led-controller[1799]: <6> 288051 Start to run STATUS_SAN 2025-09-04 00:00:00 time-settings[1852]: <6> 279504 Service start 1970-01-01 08:00:19 led-controller[1799]: <6> 288504 Service start
