It's looks like you using at your home network a different IP address like 192.168.0.x and RRC comes with 192.168.1.
Try: disconnect your Router from PC. Only a LAN cable between RRC and your PC
Go to Network settings at your PC, switch off DHCP and set yout PC to a 192.168.1.xx (fixed) address, then Power ON RRC, start Browser and open 192.168.1.227
Chance RRC TCP/IP address to and of your Router addresses area - not forget to store and Apply at RRC
Then switch back your PC to DHCP and reconnect to your Router. Try again your RRC
By the way DJ0QN is the "holly father" of RRC (at user side)
- maybe he can help
