Hello,

I have just setup a Deco M5 mesh network and everything seems stable and the speeds throughout my home are acceptable. However, since upgrading to the mesh network I have lost access to my QNAP TS-453Be. I can periodically see the NAS through QNAP's Qfinder Pro software, but it informs me the the NAS might be on a different subnet before disappearing entirely. I can see the NAS is on the network through the Deco app, but none of my computers both Mac and PC can see it.

I have the network setup as follows. 

Any help would be much appreciated.

Thanks,

James
