AX6000 V2 - latest firmware from cloud services - broken router connection of clients
Dear TP-Link
It looks like the lastest firmware of 1.2.1 Build 20250221 rel.13966 (4555) has broken the router
The router can connect to the internet ok, speedtest/ ping etc from the router interface works fine.
Any clients connected (wired or wireless) to the router, cannot connect to the internet.
Can you please fix the firmware and send me a link to a version I can upgrade my router with to make it work again.
Thanks

Thanks for reminding me of the new official firmware for Archer AX6000 V2.
The official 1.4.1 and 1.4.2 version has already fixed the issue discussed in this thread. I've just updated the official post below:
[Solved] Devices Fail to Access the Internet After Updating Archer AX6000 V2 Firmware to 1.2.1
Please check for the updates via the AX6000's web interface or through the Tether App to install the latest version manually.

Hi @ShapSMF,
Thank you for reporting your issue to our community.
May I know what is the LED status of the router now? Have all clients lost their network connection?
Please try the suggestions below:
1) Connect a PC directly into your modem to verify if your ISP Internet is stable.
2) Make sure the Ethernet cable between your modem and the Router is connected properly, replaced old cables with new ones.
3) Change the DNS Server of the Router, login the web management interface of the Router, go to Advanced > Network > Internet > Advanced Settings, change the two DNS Servers into 1.1.1.1 and 8.8.8.8. How to Change the DNS servers on the wireless router and DSL modem router (New UI)?

@Joseph-TP I have the same issue after this latest update. I also noticed that it's not possible to downgrade the firmware to the previous version. I already tried resetting the device to factory reset and configure my entire network again (AX6000 V2 EU + 2 x RE605X + 4 * RE705X) but within a few minutes the issue reoccurs and there is no connectivity on both cable and WiFI. Restarting the router does not help.On the previous firmware the router was working fine.Supprisingly,the led on the router is blue despite no connectivity.

Hi @KubaAdamus & @ShapSMF,
Thank you for your reply and testing results.
Please try the following suggestions:
1. Turn off IPv6;
2. Turn off blacklist on the Access Control page;
3. Use a PC to Long ping the router's IP(192.168.0.1) and DNS (like 8.8.8.8), How to use the Ping command
Long Ping steps:
- Ping -t <target IP or domain name>. Example (continuously pinging the router LAN IP): ping -t 192.168.1.1
- Press Ctrl + C to terminate and view the statistics.
- Please take screenshots with the testing result.
Thank you.

Problem Statement: Since the last cloud firmware update to 1.2.1 Build 20250221 rel.13966 (4555), the AX6000 V2, wired clients are no longer accessible on the LAN. The router assigns the Wired LAN devices with an ip-address. From the router diagnostic page, the LAN devices can be pinged, but any other clients connected by Wifi such as a laptop, the Wired LAN devices are not reachable. uPNP is enabled. IPv6 is off and I have no blacklist items. See ping results below

The LAN connected TV can access the internet services, such as Youtube and Netflix etc...
So the issue seems to be related to the internal routing of traffic between the WLAN and LAN interfaces.
Prior to the firmware update, there was no issue locally connecting between Wifi clients and LAN clients.
I have already done a hard reset of the router back to factory settings to see if I could flush the routing table, it still has the same issue
I hope that help you narrow down the faulty code in the firmware
Thanks
Shap

@mgvelm did you need to reboot the router after disabling the all 3 Anti-virus options?
I'm still having the same issue as before, All device can connect to the internet (Wired and Wireless) but I'm not able to connect from Wireless to my Wired devices or the other way around. Its like the internal routing table is corrupted

@ShapSMF This is a firmware error. After disabling the 3 antivirus options, everything works. The antivirus does not work, but it should. TPlink needs to fix this. I reported it to them.
