I have a Archer C2300 that I'm trying to connect to my NAS using link aggregation. The NAS has two nic's and I can see them both in the C2300 software, both have a ip and both show up as a wired connection....BUT only as long as link aggregation is turned off.  As soon as I turn on link aggregation and reboot the router the NAS no longer shows up in my wired connections and the NAS is no longer visible on the network. Then if I disable the link aggregation the NAS comes back on and shows up again.

In the NAS settings I am using bonding mode 802.3ad

In the C2300 I'm using the default SRC MAC+DST MAC (which is suggested in the tplink help article about setting up link aggregation on the C2300

Any advice or any ideas on whats going on?

Thanks!
