Local DNS is not working after applying the latest updates for ER605 V2

Friday - last edited 22 hours ago

Model: ER605 (TL-R605)

Hardware Version: V2

Firmware Version: 2.3.3 Build 20251029 Rel.18054

Local DNS is not working after applying the latest updates for ER605 V2.

After updating ER605 V2 to version "2.3.3 Build 20251029 Rel.18054", I no longer have local DNS resolution.

I thought about removing and re-adding the configurations I made, but every time I do that, I receive this error message in the application.

Is anyone else experiencing this?

Thank you for your post. We attempted to reproduce the issue you reported in our lab and found that the LAN network name you configured appears to be invalid. Please change it to a name that starts with a letter and contains only uppercase/lowercase letters, numbers, and underscores, then push the full configuration again—this should restore normal operation.
