LAN/internet connection problem

Specs: Windows XP, 3 GHz / 4094 MB
So anyways I have an internet cafe w/ 10 client PC's and 1 main server control PC. I have a 5-port router and a 16-port switch. I have ISP connection and main PC directly connected to the router and from the router a cable goes to switch and then from switch the other 10 client PC's are connected. The thing is that PC's won't connect through the switch neither to internet or the main PC. It says it has limited or no connectivity. When I connect a PC directly to the router it has internet connection but still my cafe client won't connect to the main PC control station.
Switch - tp-link TL-SF1016D
Router - Sweex 5-port (can't find the box so don't know which one specifically)
Cyber Cafe Pro 6 client
So if you can help me I would be grateful, thanks in advance.

A quick look online tells me the switch you bought is a simple, unmanaged, switch. It should be plug-and-play. Therefore your setup should work.

The first thing I would check is whether or not the switch itself is malfunctioning. The simplest way to do this would be to connect two client computers and statically assign them IP's in the same subnet. Something like the following:
Subnet Mask:


Then open a command prompt window and try to ping each PC from the other. If you're not getting proper replies, chances are the switch is no good and you should take it back and have it replaced.

If the clients do reply properly to pings, try moving the uplink cable to a different LAN port on the router.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
