Hi there, 

I has two RE450 extending my wireless networl, and I decided to upgrade in order to expand my coverage even further.

I swapped one fo the RE450 for an RE650, however it did not let the internet get thrrough. I am able to connect them, but without internet access.

I tried Router - RE650 - RE450, and it did not work, then swapped and tried Router - RE450 - RE650 and it did not work either.

I tested with two RE450's or two RE650's and it worked, but not mixed.

I mean  Router -> RE450 -> RE450, or Router ->RE650 -> RE650 and works fine

Are those two models nos compatible between them? or am I missing something on my setup?

Thanks!
