Just installed the Onkyo TX-NR626. (I had endlessly worked on a friends TX-NR616 and I hated the problems/inconsistencies.) The TX-NR626 seems to be working fine on my network (going on 72 hours), same network as my Vera3.
I have not sub-netted or anything special. If things change I’ll update.
Note:
For those using the Onkyo Remote. I use the Onkyo Remote2 on my Ipad and Iphone from App Store. Works Fine!
However, my Android App stopped working once I updated the New Onkyo Remote App. I used to use the Onkyo Remote2 App from Google Play, but it no longer exists. I found that if you install the Onkyo Integra Remote App (higher AVR Line) that my TX-NR626 now seems to be working fine.
FWIW
