Archer AX11000 v1.0 upgrade to 2.2.1 Build 20250725 rel.9119(5553)
Hi ,
I've just upgraded to firmware 2.2.1Build 20250725 rel.9119(5553) and now when I use my VPN to connect to our data center I can't copy any files from any of the serves to my local PC. This would normally work fine, I would connect to the VPN and then use Windows explorer to connect to teh URI can copy a file to my local PC.
Now the copy fails to start and all network activity stops .
The only thing changed is the Router firmware version.
Where can I get a list of firmware versions to rollback to . This page https://www.tp-link.com/au/support/download/archer-ax11000/#Firmware only shows firmware up to Archer AX11000(US)_V1_1.3.4 Build 20230906 for V1 .
If my hardware version is v1.0 why did the Check for updates button load 2.2.1 Build 20250725 rel.9119(5553) . Is it fine to use this firmware?

hello @xiekai37 ,
Could you take some screenshots with the error message and send them here?
Please manually set your DNS server to a reliable public DNS server (such as 8.8.8.8 or 1.1.1.1) and ensure the settings are correctly saved. Here are the steps to change the DNS server on your TP-Link router: How to Change the DNS servers on the wireless router?
How about other clients? Can they access the internet normally?

Helllo @ZakCT ,
Could you provide more details about your router?
Is the VPN data transmission anomaly caused by a firmware update? What VPN is it? Do you have any screenshots of the related error messages?
I will send you the beta firmware. For insurance, it's always recommended to save a copy of the router's Backup Config file before upgrading.

Hi @Jcox2684 ,
Could you provide more details about your router? In particular, what is the hardware and firmware version of your router?
If the VPN is malfunctioning, what specific aspect is causing it? For example, is it unable to resolve DNS correctly?
