I have tried unsuccessfully for over a year to purchase a HomePlug compatible surge suppressor to use with my 622. The TII HNP6xts and the Belkin F9M23-08GRY-PL are not available at retail. Monster has come to the rescue with several models that have a HomePlug compatible outlet. I purchased their MDP 900 from overstock.com for $81.44 including shipping. I installed it yesterday along with a Netgear XE 102 ethernet bridge connected to my router. The installation was flawless. The Network Setup was successful on the first try. The Dish Remote Access was also successful on the first try. The next step will be to try DishONLINE.
