I have a VIP 722K with wifi and sling adapters attached. I am trying to connect wirelessly through a Linksys E2000 router connected to a Westco 6100 DSL modem with service provided by ATT. The day I received and hooked up the sling adapter, I could access my DVR using the Dish app on my cell phone, and everything seemed to work as it should. Tried the phone app a couple of weeks later, and I get a receiver not connected message. Sure enough, the DVR tells me that it is not connected, even though it passes the wireless connection test. I have several other devices connected to this router, and they all work with no problems. At this point, I hooked the 722 directly to the E2000 with a temporary cable and still no connection, even though the router assigned it an address. I then removed the router and hooked the 722 directly to the Westco modem and get a working connection. Next, I hooked up an old Linksys WRT54GS and the 722 connects wirelessly, and everything appears to be working. I have compared settings on both routers, and they appear to be the same. Has anyone else had problems connecting through a Linksys E2000 router?
