Router vs. Hub

Hello all,

I have two computers and I want both to share the same DSL internet connection; fair enough. I thought that all I needed was a hub to connect them to, then the hub to the modem for them to do this, but two computer shops I went to didn't sell hubs and told me to get a router. I'm not against the idea, but as my two computers have software-based firewalls I don't want a hardware version to complicate things. Or can one just simply plug in a router and not install the software to control its firewall and it will work as I intend?

Cheers,
Arf.

A hub will just repeat the signal, and I dont see why it would not work, it would be less expensive, but for the cost of hardware now a days just getting the router with the added security wouldnt hurt.

Good luck

First, it depends on whether your DSL modem is acting as a router. Check the IP address of your computer connected to the DSL (Control Panel -> Network Connections -> Right click on the Local Area Connection, go to Status, click Support tab). If the IP address starts with 10. 172. or 192., you could add a hub and share that way. Anything else, you would need a router.

Software firewalls do not protect from external threats nearly as well as hardware firewalls, and it's always a good idea to have one of each. There is no software to install to control the firewall of a router, and your typical home routers just do NAT firewalls anyway, nothing too high end.

i'll just echo some of the stuff above...you could probably do this stuff with a hub...or if you wanted to get real fancy you could do some fancy direct connect between the pcs ..if all you want to do is share the internet connection...

but...i've always found that routers tend to make alot of this stuff easier...especially if you're ever wanting to throw in a home network setup...(which you can do with a hub...it would just take a little more effor)...within reason...the routers marketed for home use are becomming more and more "plug and play"...they have their own DHCP servers...their own firewalls...they usually will automatically gain access to the internet connection as soon as their plugged in to the wall...and...especially if all you're doing is sharing the internet connection...require LITTLE OS manipulation if any

Just to add one more thing to this, a hub would work, a router could be overkill if it is just sharing network resources or an internet connection at which point a switch is your better alternative.

They cost about the same as a hub, cheaper than a router and provide smart connections which a hub will not.

Can you enlighten me on the subject of "switch"?

Sure,
A hub will forward every incoming packet out through ALL of it's ports, regardless of whether the port is being used or regardless of its destination. Since every packet is being sent to every port you get "collisions" which impede traffic on the network. Obiviously, this isn't real efficient.

A switch, on the other hand, isolates ports -- every received packet is sent out only to the port on which the target may be found (one caveat - if the proper port cannot be determined, then the switch will broadcast the packet to all ports). The switch is intelligently sending packets only where they need to go, and not everywhere willy-nilly. Obviously this IS more efficient.

Hope that clarifies things...

Very well put, maybe a thread explaining basic networking equipment (routers, hubs, switches, cat5) and their ideal uses is needed so all the users have a nice quick reference guide to avoid searching threads upon threads. Just a thought :whistling:
