Most home routers are set up to automatically assign IP addresses to all the devices on the home network using DHCP. Most home networks use an IP address in the range of 192.168.x.x, but some also use the range of 10.0.x.x. The router is generally configured to use a range of IP addresses for this, such as 192.168.1.100 to 192.168.1.255. However, some routers only specify the starting IP address and the number of DHCP clients that are allowed. In the previous example, it would be a starting IP address of 192.168.1.100 with 156 clients allowed. In order to see what this range is set at, you will need to log onto your router. Most routers are setup with an IP address 192.168.1.1 or 192.168.0.1. Check your router documentation to determine what the default router IP address is.
The main issue that seems to occur when using MRV and being connected to your home network is that receivers will start to drop off the network with no indication as to why. The belief is that there is some issue with how DHCP leases are being handled by the receiver. When the router assigns an IP address to the receiver, it is only for a limited amount of time. When that time is about to expire, the receiver is supposed to request the lease to be extended. While the receiver thinks the lease has been extended, it seems that routers are not really doing this, thus the receiver drops off the network.
One way to troubleshoot this issue is to remove the Broadband DECA that bridges the receivers to the home network. Restore Defaults and Repeat Network Setup under Network Setup and they will revert to an internal IP address (169.254.x.x). It can sometimes take a little bit of time before the receivers will see each other using this IP address range, but it should work. Obviously, if MRV is now working fine you are back in business, except that you don't have access to your home network or VOD/PPV.
Since the issue seems to be with DHCP, the next option is to assign IP addresses to your receivers and bypass DHCP. Make sure the Broadband DECA is connected if you had previously disconnected it. Go into Setup and select Network Setup and then Advanced Setup. Here you can manually set the receiver to the IP address of your choice. Make sure to pick an IP address that is outside the DHCP range on the router. So, using the example from before, you would select an IP address below 192.168.1.100.
Use the following info for the other settings:
Subnet Mask: 255.255.255.0
Default Gateway: <your router IP address>
DNS: <your router IP address>
Once you have done this, you should be able to connect to the Internet and also have MRV without the issue of receivers dropping off the network.
