Have you checked with the Bell Aliant threads? There are many posts where members (like me) have been able to get rid of the Actiontec supplied by Bell. Might or might not work for you but what's the risk?
Yes, the HH2000 is better overall, but it's still not as good as having say, an Asus AC66U or greater.
They are still limited in the number of wireless streams and overall control of the router.
If you have FTTH, you can pull the entire Bell router right out of the config as well.
