Weird networking problem

[AzJazz]

I am trying to help a friend who has an Apple PC on a wired LAN.

The LAN has a DNS server located elsewhere on the network. His PC is connected directly with what looks like a TIA/EIA-T568B cable.

When his Apple PC is directly wired, the PC gets it's LAN TCP/IP address and other network configuration information fine.

However, the weird stuff starts when I try to add a switch into the mix. When I insert a switch between the PC and the normal LAN connection, I can't get any network configuration information/internet access - although there are flashing lights on the switch for both the LAN and PC connections.

What is going wrong?

Thanks,

AzJazz

Have you tried the switch elsewhere? Could be just bad. Flashy lights don't always mean things are working fine.

Switch may have an uplink port configured, or needs one configured before it can connect to the network also.

model switch?

hang-the-9: This is the 3rd switch I've tried, all with the same results. Internet OK when directly connected, dead when going through the switch.

model switch?

Emerald: The switch is a Cisco/Linksys EZXS55W 5-port Workgroup switch. I purchased it because it had MDI-X built in (figuring that it would remove at least one potential issue).

Try setting the IP settings manually see if he can connect then. Who controls the LAN? Did you check with them?

connect the network cable to the port next to the power connector. It is called an Uplink port. when using the Uplink port you will not be able to use port 5which is to the left of it.

then connect the Mac to port 1 which is on the far left.
