I'm out as well. Both 622 receivers. DHCP is working fine and assigning all the appropriate info to the receivers. Voip hooked to the same router is working just fine as well.
Today I've been resetting my router, rebooting the boxes, and replacing my ethernet cables to the homeplug device...all to no avail. But, glad to know its not something on my end.
Same problem here with my 622. I called Dish and they told me I had to contact my Internet provider. I told them I tested everything on that end and the issue is only with the 622. She just repeated it's not their problem. nice. I'll give it a day or two and hope it comes back on line. Maybe they're finally going live with the remote timer setting.
