I don't know when this started, but I have at least one definate problem and one questionable occurrance with my ViP622.
I have noticed recently that when I turn on my receiver and go into Diagnostics the connection tests fail. I then see that it has no Dishcomm functionality nor does it see my router anymore. I have changed nothing in my configuration recently to cause this... but if I perform a front-panel reset then it comes back with an IP address from my router and then passes the Dishcomm tests.
I shouldn't have to do a reset every day, especially since it goes into standby every night anyway... so this seems like a problem. I don't know if this is related to L4.49 or if something has started to fail hardware-wise in the receiver but it is becoming annoying, especially when I see that it is failing to call in and rescheduling to try again later.
The fastest way to get an IP address from the router is not to do a reset but to go to
Menu/System Setup/Installation/Broadband Setup/Network Setup/Reset Connection.
This will ask the DHCP software in the router to assign a (possibly new) IP address to the receiver, which you should see displayed on that screen.
There may also be a variety of problems with your router. Depending on the brand and model, if the router is powered down or reset, it may not recognize the receiver until the next time the receiver asks the router for an IP address. Each IP address in the routing tables has a lease expiration time, which is 24 hours in some routers, which the software in the device knows, before the expiration time has elapsed, to send a request to the router to renew the lease of the IP address for another period. This process may be broken. You could try resetting your router, then going through the Reset Connection process described in the previous paragraph, and see if your problem recurs after that.
