MBP to SSD on Eero wifi

An external drive is not a network attached storage (NAS) device. You either need a router that supports connecting an external drive (eero does not) or you need a proper NAS enclosure.

Personally, I have a QNAP NAS with a pair of 10 TB HDDs connected to my eero, for wireless Time Machine backups of several Macs in the house.

I successfully backed up my laptop via Time Machine when connected directly, but when I attach it to the wifi network, it's not recognized.  Is there any solution? Appreciate guidnce. Thank you

Did you try connecting the Sandisk drive via a USB port?

I would think the Sandisk had a USB cable you could plug into the router directly...

unless you are saying the Sandisk shipped with USBC

SanDisk has USB C port, which I connected the router to USB C with an Ethernet adapter. Eero router does not have a USB adapter.
