| 420728 | 2006-02-01 00:49:00 | A router separates TCP/IP subnets, where a switch/hub work within a subnet. Routers are "smart" complex devices, and by comparison switches/hub are "dumb" simple devices. Long and short of it, you'll need to configure several network settings on throughout the network, if you have any hope of it working. Generally not worth the trouble unless you're planning a large complex LAN. my flat mate has another router, can I just hook that up to my current router so that i have enough ports for everyone else, without having too much trouble? |

The other goes to the LAN side, with a switch on it,with multiple ports (WAN)----(Router)----(LAN)---(switch)---ports If there's nothing attached to the WAN side, it can't route packets from the LAN side out to it, and it won't get any packets from it to be routed to the LAN side. If it doesn't know to do anything with LAN traffic on the switch, it won't do anything to traffic on the switch. The switch will work as a switch. It's well worth trying. You might need to set the router up to do nothing. Nothing clever required. |

| 420730 | 2006-02-01 02:14:00 | Whenever I have a LAN with my friends, we daisy chain a few ADSL routers together & don't have any trouble using them as dumb switches. I don't see why it would be any different for a router without the built in modem. | Greven (91) | ||
| 420731 | 2006-02-01 02:33:00 | To save on cabling, you could hook the switch, or spare router, up on the nearest PC. It will all work the same as far as the person connecting to the net is concerned. | Murray P (44) | ||

If you are using an additional router you would need to be careful of the setup. Most adsl routers (and routers in general) assign addresses using dhcp and it wouldn't be a good idea to have both routers assigning addresses on the same net. So either disable the dhcp server on one router and use the switch as suggested or plug the wan port into the existing router and have the additional PC connected through the switch side of the second router. With the second option you would possibly need to reassign the router address though. Have fun! |

| 420733 | 2006-02-01 13:14:00 | A router separates TCP/IP subnets, where a switch/hub work within a subnet. Routers are "smart" complex devices, and by comparison switches/hub are "dumb" simple devices. While Hubs are Dumb most switches are far from dumb and do much more than simply moving data. Hubs broadcast data to all and those that need it take it. Switches however only send data to those that requested it. Some switches are even more complex and have IP addresses of their own that you program through. |

| 420734 | 2006-02-01 22:15:00 | "Dumb" and "smart" are all relative. Routers have more intelligences since they have to be aware of two or more networks, and route traffic accordingly. | kingdragonfly (309) | ||
| 420735 | 2006-02-02 00:26:00 | A hub is a "multiport repeater" . It regenerates all the packets it receives on its RX side any port and retransmits them on its TX side of all ports . It pays no attention to the contents of the packets . A switch is a "store and forward" device . It reads the addresses on packets . It remembers the addresses of the hosts connected to it, and it sends each packet to the host it's addressed to . It maintains its own table of IP:MAC mappings . Because of this, I have the subversive idea that a hub will give a faster network if the network is small . :D A switch gains in a busy net because it avoids most collisions . (It can't avoid collisions caused by having a busy server) A small network which has no collisions will have reduced latency because the packets are just broadcast by the hub, rather than being stored, having some decisions made, then being transmitted to its desination by the switch . The speed difference would be small . I'm going to do some measurements one day . |
