Greetings:

Since my cable connection comes into my house in the basement, Ive modified my home network configuration by adding a router in the basement so that I can move my wireless router to an upstairs room to get better coverage. The new configuration looks like this:

Primary Router:
    Workstation 1 (Wired Connection)
    Secondary Router:
        Workstation 2 (Wired Connection)
        Laptop (Wireless Connection)

This all generally works, but Ive noticed a decrease in speed and reliability of the network. Occasionally, the connection of the computers connected to the second router is effected by the connection of the computer connected to the primary router.

Any suggestions would be appreciated. The router models and configurations are listed below.
