Question about Puredata (PDC8023UAS-16FX) Networking Switch

Connecting to the Internet with more than 1 computer (using a PureData 16 port device)

I am not able to connect to the Internet with more than 1 computer at a time on my home netwrok (I have a PureData 16 port network device). In order to connect to the Internet with my laptop I need to unplug the modem and then re-plug it in and then I can access the Internet with my laptop (but at that point my desktop cannot connect to the Internet). My providers' help desk says it's a question of recognizing the MAC address and the problem is in the hub device.

Re: connecting to the Internet with more than 1 computer...

The PureData 16 port is just a hub and does not perform any of the housekeeping functions you would need in order to create a home network and connect several computers to the Internet at the same time. The reason why your procedure works is because your service provider by default will only allow you to have one IP address. When you unplug your modem that forces the providers equipment to reconnect to your computer and reissue the IP address. The way to get your desktop and laptop to connect simultaneously is to go down to your local computer store and purchase a home router/firewall. I?ve seen some on sale for as little as $35 at times and are fairly easy to setup. Good luck and let us know how it goes.

How to connect also sonet zfs3116 to my home system

can't find manual for it but it says it's a 16 port. If all 16 ports are labeled identically, just use a standard ethernet cable (i.e. patch cable) from the switch to your router. If there's one port that is a different color or labeled uplink or labeled 'wan' plug that into your router. Then plug all your other devices into the other ports.

I'm assuming you have a router. If not get one. You should not be connected to the internet without a router.

Internet not working

Make sure the router is set to DHCP to avoid any IP conflicts. This may be caused by connecting a switch before the router and blocking the routing table.

Got a hub genius GH4080SE and trying to connect computers, pls advise what is the steps?

Hardware Setup

1 Find the WAN or uplink port of the Ethernet hub. Typically, it is located on the rear of the unit, and it is often separate from the LAN ports.

2 Connect an Ethernet cable from the WAN port of the hub to either the Ethernet port of the internet modem or, if expanding a network, to an empty LAN port on the existing network’s router, switch or hub.

3 Plug an Ethernet cable into one of the LAN ports on the Ethernet hub and connect the other end of cable to the computer or device that will be added to the network. Repeat for any other devices that will need to be on the network.

4 Power up the Ethernet hub and the computers or other devices attached to it. On the front of the hub will be a series of LEDs that correspond to each LAN and WAN port on the hub. Every port that has a cable plugged into it should have one or more of the LEDs lit that represent that port. If not, check the connections and swap out the Ethernet cable if necessary.
Software Setup

1 Configure the network settings on each connected computer. If you are expanding a network and the network uses DCHP, or dynamic IP addressing, no configuration will be necessary. On networks using static IP addressing or on a new network setup using the Ethernet hub, each computer or device must be assigned a unique IP address. Local IP addresses must use the allowed “private” address pools that will not interfere with internet addresses. Acceptable addresses include 192.168.x.x, 172.16.x.x to 172.31.x.x, or 10.x.x.x. The “x” represents a number that is chosen by the user, from 0 to 254. All computers on the network should share the first three numbers in the address, with the final number representing the individual computer. In a network with three computers, for example, the first could be, the second could be and the third could be, though the final number does not need to be sequential.

2 Click the “Start” button in Windows, select “Control Panel" and double-click the icon labeled “Network Connections.”

3 Right-click the icon for the Ethernet adapter and select “Properties.” Click on the check box marked “Internet Protocol (TCP/IP)” and press the “Properties” button.

4 Select the radio button labeled “Use the following IP address.” Enter a unique IP address for the computer and the applicable subnet mask. If a router is used on the network, enter the router’s IP address as the default gateway. Press the “OK” button and reboot if necessary.

5 Enable file and printer sharing from the “Properties” dialog for the Ethernet card if files will be transferred between the networked computers.

6 Click the “Start” button, select “Control Panel” and double-click on the “System” icon. Select the “Computer Name” tab and click on the button labeled “Change” to set the computer’s network name. In the “Computer Name” box, enter a unique name for the computer. In the “Member of” section, choose the radio button marked “Workgroup” and enter the workgroup of the network. If setting up a new network, this name can be change but all computers on the network must share the same workgroup name.

7 Verify that all computers can access the network and the Internet if connected.

How to connect 4computers with Swith or Hub

A switch or hub isn't very complicated.The primary benefits are connecting more than 1 computer and/or increasing the range of your wired network.
On the back of your switch,all you do is plug in each computer using an ethernet cable,plug in the switch power supply,and turn it on.The only caveat being if you're using 1 PC to connect to the internet,it should probably be plugged into port #1.It probably doesn't matter,but I'm not familiar with your brand of switch.
If this helps,would you please rate my post?

5 port network hub

Connect the power supply.
connect the ethernet cable from your router (or the box that your isp gave you to get the internet connection) to the port labeled "Uplink" on the hub.
Connect the ethernet cable from your computer or another device to be connected to any of the ports 1 to 4. Do not use port 5 (that port is used to "chain" another hub)
Please be aware that a network hub is basically a very simple device that will not assign an internal ip number to your devices or computer, and if you have two or more devices or computers, you do need that either your "modem" (the device that is installed by your isp) is capable of handling more than one computer, or you will also need something to act as a router (your computer can do it, but you will need to know how to set up that).
Hope it helps

How to link with 16 port switch with 8 port switch

Good question.
To link the new switch, take a short cable from the LAN port on the new Switch and connect it to one of the existing ports on the old or connected switch. it's just a daisychain.
Just keep in mind that the LAN connection on the Last switch must be connected to a PORT on the prior device on the LAN.

Linksys EZXS16W Issue

Hi There, first of all you need to connect from your modem or router's port a link. Use a cat5 ethernet cable from the modem to the switch or if you also use a router from a port in back to the switch. Then when you plug in other computers it will see the internet connection. Good Luck...

Cannot share my cable modem connection

You need to connect a router to the cable modem.  The router then gets an IP address from Comcast and provides a gateway between the computers connected to the router.
The modem expects to communicate with a single Ethernet device, and provides an IP address to the first device that provides a piece of data called a MAC address.  By placing a router in-between, the router gets the IP address that lets you communicate on the Internet.  It provides local IP addresses to the equipment connected to the local Ethernet and "routes" those to the Internet.  You can either hook your two devices into the router if it has enough ports, or hook you switch to the router and hook your PC and PS3 into the switch.

Network my desktop with my laptop

Internet -> Port 1 or 16 ComputerA -> Port 2 ComputerB -> Port 3
I say port 1 or 16 because on older equipment there is an uplink port that is usually either the lowest or highest port number depending on the manufacturer. Set both computers IP addresses to use DHCP in this scenario. If you aren't connecting to the internet, both computers need to have their ip address set manually to a number in the same "neighborhood" (i.e. set A to and set B to, then they will see each other.

SMC ethernz problem

Typically you will connect your router to port 1 of the switch. Unless you have a port that is labeled WAN or Uplink. Then you would use that.

Daisy chain is when you have multiple switches connected to eachother. So it would be router to port 1 computers on ports 2-15, port 16 would connect to port 1 on another switch, and so on.
