so I have the AE in the living room, and Id like to run some Cat 5 from the AE to the office and also to my bedroom. Im not to savy on how Cat5 can be split with couplers. If I ran one cable from 1 of the 3 ports on the AE into the wall, under the house, and into my bedroom, can i splice into it midway along the cable and run another wire into the office ?? will the AE allow 2 computers to be connected to one port? port 2 of the AE goes to the XBOX 360 and port 3 goes to the printer in the living room where the modem is.
