According to reports, Version 1 units had mesh capabilities that worked with certain extenders. However, Version 2 firmware is reported to have either significantly altered or completely removed this support, causing major compatibility issues with mesh extenders. One user's experience highlights this problem: they purchased a TP-Link RE815XE extender (which uses the "OneMesh" standard), expecting it to work seamlessly with their VX420-G2h V2. They later discovered the VX420-G2h uses the "EasyMesh" standard, and even then, the feature was effectively non-functional in the version of firmware their ISP provided. This incompatibility rendered the mesh extender useless for its primary purpose, forcing it to operate only as a basic range extender.

If you are experiencing issues on an ISP-locked device, it is often better to contact their technical support to request a remote firmware push. Troubleshooting Common Issues
