Help setting up network switch


R

Richard in AZ

I have a 4 port DSL Modem/router and all 4 ports are in use.
I would like to add one more PC to the network.
I purchased a Linksys Switch and the instructions are to plug the uplink into one of the router
ports,
then plug the existing device (a network backup drive) and the new computer to the switch.
However, I can not get and IP address for the computer.
I can see both the computer and external drive on the network,
but the computer is connected to "local only"

The router is set to automatically assign IP addresses and works fine without the switch.

Any suggested tutorial on this subject, or direct help, would be appreciated.

I recently set up a network (4 port wireless modem and an 18 port switch) in
the same manner you did. It should work as you have it setup; therefore, I
suggest you call Linksys support.

If you are connecting *2* devices to the switch (your network backup
drive and your new computer) and *one* of them gets an IP address but
the other does not, make sure that when you originally configured the
router you didn't limit its DHCP server to only 4 IP addresses.

Hard to tell if the external drive gets an IP address as it has no smarts to go on the internet.
I can just access it from any computer on this home network for backup purposes.

A local IP address has nothing to do with going on the Internet. If you
can access the "network aware" drive from any computer on your LAN, it
*has* an IP address.

The fastest way to test the hypothesis I offered is to disconnect the
external drive from the switch and leave just the new computer connected
to the switch.

For best results, turn off the new computer, then power-cycle the router
(turn it off and back on). Wait until the router stabilizes and boot up
the new computer. If it gets an IP address now, you'll know that you
have to reconfigure the router's DHCP server.

One other possibility is that the Ethernet cable that you're using to
connect the new computer to the switch is bad.

If you happen to have an Uplink port, usually the very next "standard"
port is not to be used. The standard port next to most Uplink ports
is a "shared" port with the Uplink port. It should not be used at the
same time as the Uplink port.
