Hi there @ronaldtao, please complete the factory reset as @KeithFrench suggested. Will take it from there afterwards.

Thank you @KeithFrench

Normally, @ronaldtao when you see the error that something wrong happened, you need to do a factory reset on the router. This can be especially true with hardware revision 3 on the 5364; V4 is not affected by this.
