Hello  @obagi ,

Welcome to our community.

According to Google Translate, your question is the RE700X reboots in a loop after the firmware update. If there is any discrepancy, please describe it in English.

May I know if your network topology diagram is as follows:

ISP modem—router)))((( RE700X

(Note: — stands for wired connection,)))((( stands for wireless connection )

Have you created an EasyMesh Network between the router and RE700X? What model is your router (or the device connected to the front of the RE700X)?

If you disable the EasyMesh feature, can the RE700X work normally?

Do you know if there is any error message on the Management page? Please take screenshots with the error message and send them here.

Hello @obagi ,

When you restart the router, does the power light only come on?

If you have a wired PC, connect it to the RE700X and verify that it can establish a connection to the network.

Or, you can check the Ethernet status on the PC as follows:

If you're unsure, you can take a photo of it and send it here.

Do you remember the firmware version you were using before the upgrade? Have you tried any way to recover the firmware?
