I can’t change the channel or anything inside channel & Power
i have same problem Networking Issue Cannot communicate with device. Please check your network connection.
The first thing I’d try is rebooting the device. You obviously have a network connection to it or you wouldn’t have gotten as far as you did. However, the connection could be intermittent. If this is the only tab you’re having problems with, then a reboot. If you’re having problems getting to other tabs also, with the same error message, then I’d say that you have an intermittent connection. Are you connecting to the device via Ethernet or across the wireless connection?
