The uplink of the D-Link hub is connected to a Voyager 2000 DSL modem. Two desktop PCs (one running XP, the other Vista) are connected to the hub with standard ethernet cables. I can see the Internet from both PCs and connectivity to the modem and out to the internet is fine. However I can't see either PC from the other. The modem has assigned 192.168.1.3 to one PC and 192.168.1.65 to the other. When I try to ping either of these addresses from the other, I get all request timed out. Please help! TIA

The D-Link DE 809TC is a wired hub - it does not include any support for wireless connectivity. On the back of the device you'll find nine RJ45 Ethernet connectors. Eight of these connect to arbitrary local network devices and the hub distributes any network package directed to the local network (regardless of its origin) to all of them. The ninth connector is an uplink. It receives packages from/to other networks. This is *all* this device can do; forward packages to all other devices on the eight internal connectors or from/to the uplink port. It has no logic to selectively forward packages to dedicated ports (that is what a switch does) or connect to DSL service providers (like a DSL router).
For your problem you would need a router with wireless LAN support, e.g. D-Link DAP 1360.
switches cannot be connected to the Cable modem....
because NAT will not be enabled in cable modem....so there wont be any DHCP server present in the cable modem....
Nat will be enabled only in DSL modem like AT&T verizon etc....So DHCP server will be present inside DSL modem...that is the reason why switches can be connected only to the DSL modem....
With NAT enabled modem, switch will work as a switch....
With NAT disabled modem, switch will work as a hub....
This is the difference....
Any doubts further ? please clarify with me.... I am ready to help you....
1.) The setup needs changing
2.) first off the dss-24 is a network switch not a router
3.) all of your pc equipment should be pluged into that device.
4.) chose one port as an uplink to your att modem
I think your problem is that the new modem is only giving out one ip address. So what ever first pc is turned on that is the one that grabs the address.
5.) you will most likly need a router to take the one ip address assigned via att then dole out additional ones. Remember the dss-24 is not a router. It simply connects everyone together. Each device still needs an ip address given from somewhere. Your old cable modem probibly did that but your new att dsl most likly does not.hence the new router will do that.....
to set it up do the following
2.) Find out the ip setup needed for your dsl service
A.) gateway ip
B.) primary & secondary dns server ip`s
C.) subnet mask
3.) get into the setup of your new router and then plugg in
all of these values using a fixed if address in the router
4.) connect routers wan port to one of the modems port. u may have to use a cross cable or straight look at the link lites to find out if they are talking to each other
5.) make sure that the routers lan side is setup for DHCP
6.) connect one lan port off the router to an uplink
of the dss-24. Then reboot everything
7.) viola it should all work internet on evey machine and file sharring.
If your hub has 4 or 5 connectors, connect one port to your router. This device will NOT work when connected to your cable modem, as the hub does not manage IP addresses like a router does. Hope this helps ... the remaining ports will feed internet, but not provide Internet addresses to a computer.
Maybe your cable is bad. Have you tried a different cable.
I just read the specs and it seems like quite a modern switch. I'd be surprised if the ports aren't auto sensing so either a straight or cross over cable should work.
You could try a factory reset on the switch.
Another idea is connect to your DSL modem direclty from you pc and from your browser open the modems config page There should be some kind of event log in there somewhere. See if anything gets logged when the link goes down. It might give you some idea where to look. Your modem manual should tell you how to find the event logs. I take it your DSL modem only has one ether net port?
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 192.168.1.100 mask 255.255.255.0 and PC2 IP address as 192.168.1.101 Subnet Mask 255.255.255.0 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.
Are you trying to set up router ? You can set up your router manually, without the CD. Make sure that your computer is able to go online directly through the modem. If your computer is able to go online through the modem, that means the modem is working fine. You will need to connect the computer to the router and the modem to the router. open the set up page of the router and change the settings of the router according to the ISP.
Sounds like you may need what is called a "Crossover Cable' connecting your router to your hub, or if either device has an uplink port, use it on one device to connect to normal port on other device. Here are instructions for making your own cables:
