Connecting a hub to my switch/router network
Posted on 2011-03-15
My office currently has one network connection. Lately I have been testing machines and running an additional laptop. It would be almost impossible to run another wire to the office. i have an extra hub (Netgear EN104tp). It has 4 ports (1-3 are normal and 4 is labeled Link Rx). There is also a Normal/Uplink button. Whenever I try to connect the cable in my office (that is connected to a switch, which in turn is connected to a router) to port 4, and then run another wire from port 1 to my computer, the router stops working. The network stays up, but the internet goes down for everyone in the building. I then disconnect the hub, reset the router, and everything is fine again.
What is the problem?
Do I use uplink or normal?
Do I use a crossover cable or straight thru?
Thanks in advance for your help.
