I am trying to connect Four DSL lines via Connex (thompson) Routers to a 48 port 3Com switch to feed 30 PCs which are controlled by a server running Cafesuite. Currently they are all connecting to the internet through one DSL line and router everything is running ok but I am assuming it will not be long before it falls over.

Re: trying to connect 4 dsl routers to 48 port 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.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Does the non wifi modem give out DHCP addresses?
Can the wifi modem be set up to receive it's IP address from DHCP?
If the answer to both these questions is Yes then that's what to do as a first step. Make sure the wifi modem DHCP service is disabled as it must NOT give out DHCP addresses.
Connect the ethernet port of the non wifi modem to one of the LAN ports of the wifi modem and NOT the DSL/WAN port. The wifi modem is not participating in any DSL connectivity at all so it's DSL light will remain off. The non wifi modem is doing the DSL duty so it's DSL light should be correctly illuminated.
You did not explainhaow you connected all your equipment together. Connect your PC and PS3 into the 5 port switch. Connect your DSL modem into the 5 port switch, if there is a WAN/internet port on the 5 port switch then connect the DSL model into this port. You may need to power off the 5 port switch wait a 1 min and power up the 5 port switch again so it can setup an IP address table for the connected ports. If this still does not work the replace the 5 port switch with a normal 5 port hub.
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?
I am not familiar with that router so I will provide general knowledge and you can apply it to fix your problem. It sounds like your cable modem is willing to supply a single IP address. This can and should be connected to the WAN port of your router. The problem is that the router is not assigning IP addresses to the equipment that is connected to its LAN ports. Instead, it allows that single cable modem IP to be assigned to connection #1 and everybody else gets nothing. Get the computer working through it, connect to the router as per the owners manual and turn on NAT or DHCP, whichever it offers. Reboot the computer and connect xbox and you should be good. This was probably not an issue with DSL because your DSL modem would supply up to about 10 IP addresses and they also passed through the router.
The problem can be caused, because of two reasons, one the router profile on the computer has got corrupted and second the router itself. Have you tried resetting the router to factory defaults.. Caution: all wireless security settings and user name and passwords would go back to factory defaults.
1.Disconnect all cable from the back of the router.
2. Shut down your computer and the DSL box
3.Press the reset button, using a paper clip at the back of the router.Keep it pressed for 5 seconds
4. Disconnect the power cord to the router
5. Switch on the Dsl box, wait for the lights to stablize
6. Reconnect the interenet cable and the power cable to the router and power it on.
7 Let the lights stabalise on the router and power on the computer.
Check if that resolves the problem, if not we might need to update the router.
two things are you hooked up from the dsl to the router via Ethernet or usb is so check the settings in the router, it should be auto, so it could choose but lets not assume anything.may sure dhcp client or server is enabled on the router, if not it would not pick up the ip adddress from dsl. Is the mac address of your computer hardcoded to your dsl, if it is then you would have to clone your pc mac to the router for it to work. If this is not the case, try a different router if it works the router is faulty. if that does not work plug the dsl directly to the pc and go to start, run type ipconfig /all if you recieve an ip address and you can see a dns address from your isp and you can go to the internet, then the problem is your router, if not the problem is with you isp dsl, please contact them. was this helpful let me know.
