So, I understand that when your friend opens a browser window on his desktop PC and attempts to connect to http://192.168.1.1, he does NOT get the login screen for his router? If that's the case, then I would suggest turning off the SB, disconnecting it completely from the router, and reset the router to its default (original out of the box) condition. Then set up the router with the PC and confirm that the router is correctly giving a dynamic IP to the computer. Then, with the PC, program the router to assign the static IP address 192.168.1.254 to the MAC ID address of the SB. Then program the router to forward port 5001 to that static IP address for both the TCP and UDP protocols. Then, turn off the router, connect up the SB's ethernet cable to one of the LAN ports on the router, then power up both the router and the SB and see if your run the setup routine for the SB.
