Recently installed new AX11000 router as my main router.  One of it's wired connections goes to a TP-Link GigE switch.  In turn this switch is connected to a number of devices and has a line going to a TP-Link TL-SG1008MP PoE switch.   The PoE switch is connected to a number ot IP/PoE cameras that previously worked with same configuration except had a ASUS router in place of AX11000 router.

I am unable to see/connect to any of the devices connected to the PoE switch.

Have 20+ devices both wired and wireless that are working coorectly including wired connections to the first GigE switch.  I do have a couple of MAC addresses/unidentified devices in my client table but am pretty sure they are not any of the IP cameras.  Have a utility to "find" IP camears with in a segment and it is coming up empty.

Any thoughts why I am having issues ith the PoE switch?  Some weird compatability issue?

Thanks
