My brand new TC is knocking out my internet
I Have recently purchased a brand new TC. My TC is in the middle of my house. It's creates a wifi network. I have 2 airport expresses that are connected via Ethernet to the TC. They are at either end of the house. I have tried all configurations but the only one that works is if we set up the Airport Expreses as creating a wifi network. Ever other configuration (ie extend or join) kill the Internet connection.
Just ust doesn't sound right. I think it points to something wrong with the brand new TC but would like your opinion first. Thanks. Steve
