Out of Network ports
« on: October 09, 2005, 05:31:42 PM »
I need a little technical advice.
I have a LinkSys Wireless router with 4 Ethernet ports.  I have our three office computers on the ports and one laptop is wireless.  I just got a new HP printer  that has a built in Network card so it is now on the 4th port.  
Then I bought a new 4 in 1 Printer, Scanner etc which also has a built in network card.  I want to get it on the network as well but I am out of ports.  On my old Ethernet hub it had an Uplink port that was for expanding to another hub.  This wireless hub does not.  Can I just free up one port on the wireless hub and use a cable to connect to the other hub and then use its port for the two things?  
Also if I can do I need a special cable, null instead of twisted?
Thanx, for any help you can give,

BillB

Come out of any data port on the router with a standard patch cord and go into the uplink port on the old switch. If it says "uplink", it already has crossover built in (most new switches automatically detect the signal and don't need a special cable or uplink port). The uplink port is probably is next to port 1 or port 5. When you're using uplink, you cannot use the adjacent port.
 
I recommend making the interlink, then plug a computer into the switch and verify that you've on the network. Once you verify the switch is sending network data, you can rearrange who's connected to which if geography doesn't dictate connections.
 
Remember that the wire between the router and switch is carrying the data from everyone on the switch to everyone on the router. You may get slightly better results if your computer and primary printer are on the same switch. Try to visualize:

Devices A, B, and C are on the router. Devices D, E, F, and G are on the switch. D can talk to E and F to G carrying on two 100 Mbs conversations simultaneously. However, if D talks to A and E to C, you’re restricted to a total of 100 Mbs going across the uplink cable.

Practically, this is not significant for a few devices unless you’re regularly moving 100 MB files or working with a large database across the network. Remember that an internet connection delivers 1% - 5% of what the local wired network can handle and all your wireless devices are sharing 5-50 Mbs of effective throughput under the best of conditions. If your old hub is truly a hub (they’ve been rare in the market since the early 00s), everything connected to it shares a single 10 Mbs bandwidth.

Definitions:
Mbs – mega bits per second. Translating to file transfer, divide by approximately 20 to convert bits to bytes and allow for overhead.
