How to add DSL gateway to hub, for Dummies

[baracuda]

I bet this is basic networking 101 stuff for most of you but I don't get it. We have a netgear NE116 hub and about 10 computers networked using static ips. The cable guy comes to install dsl DSL by adding a Cayman 3546 gateway and assigns a static IP gateway and identifies 5 usable IPs in the same range as the static ip gateway (I thought dsl required a dynamic IP) - what are the extra 5 IP addresses for? Are we supposed to change the static IPs on our network to fall within the available addresses (obviously with 10 computers and 5 addresses that is a problem)? He configured the DSL router Wan side as static using the gateway IP address and the LAN side to use the built in DHCP server (static). When the cable guy couldn't get the network to access the internet he gave up and left it for me. What do I need to configure on each of the networked computers so that they will see the router and be able to connect to the web? Is there a DHCP setting I need to make? If I change the network setting on a computer to dynamic, that computer can access the internet but not the network. About half of the computers are Win98 and half are WinXPP. Thanks in advance.

I'll always have a problem mixing old HUB 10mbps and switches 100 mbps. My advice to you is to change the 10 mbps netgear HUB to a 10/100 switch with at least more than 10 ports.

ADSL:
1. WAN side either static or dymanamic will work, it depends to ISP.
2. Enable NAT.
3. Enable DHCP

Cable (connection between PC Switch and the ADSL switch):
'Straight Cable' if the switch got no UPlink port then use cross cable.

PC:
Configure PC to get ip address dynamically.

Thanks Ricpinto. I will try your suggestions but have a couple of questions based on your advice. 1. If I configure the PC's to get their IP's dynamically, they don't see each other (ie, can't access the network). How do I then get the network to work? 2. Would changing to a 10/100 switch be any more complicated than just replacing one piece of equipment for another?

1. Most probably PC is not getting ip address, check DHCP from ADSL whether it's working. What's the result if you run ipconfig/all ?

2. Do this test:
a. connect the 3 PC directly to Cayman 3546. What's the result? Is there a internet connection? Can they see each other?

b. If there's no problem in a. then connect hub to adsl and connect some PC to the hub. What's the result?
