How do I configure the OfficeConnect TP800

There is nothing to configure. Hubs simply spit a network connections almost like a TV cable splitter divides cable for separate rooms.

Hubs require a router that manages the network by providing IP and other network management tools.

3com 8 port hub not connecting to 2nd pc

Be sure that when you say its a hub that is indeed a layer 1 device which is just passing the signal and data along to all ports. Be sure to check the cable on the second device. At this point it must a straight cable you use to connect the PCs to the Hub. PCs transmit on pins 1 & 2 and Receive on 3 & 6. Hubs are the opposite. So a crossover will not work. You need PC pin 1 & 2 Tx to Hub Pin 1 & 2 Rx and over to PC pin 3 & 6 Rx to Hub pin 3 and 6 Tx. Tx = transmit and Rx = Receive. Also assign an IP address on each machine that is in the same subnet as each other. Such as PC1 mask and PC2 IP address as Subnet Mask This way the 192.168.1 is the same for 8 PCs and the only change is the last number (octet). Also keep the speeds at either 10/100/1000 what ever the product is rated for but always keep the duplex half. Half is good because on a layer 1 hub, everyone is broadcasting at the same time. So you have to have half of all the ports listening at all times.

I hope this helps. My advice is to buy a layer 2 switch.
