Until recently, I had 3 computers running off the same router. They were all configured to work on the same homegroup. Everything worked fine.
Now, to extend the wireless to another part of my house, I have put a second wireless router between the line from the first one and one of the other computers.
Now, that computer cannot see or be seen by the other 2 computers.
I assume it is basically creating a second or sub network and the 2 cannot communicate.
Is there a way to configure the second router so the computer beneath it can communicate with the other computers in the LAN?
