When connecting a switch/router to another switch a specially-wired crossover ethernet cable is necessary, unless both units are designed to automatically determine whether they need to operate in crossover or "uplink" mode. This is more than likely the problem you are encountering.

They cannot have the same IP address due to the mechanics of DHCP. Buying a cheap 50$ router (not switch) will fix your problem as your internet service provider will see that device as a single unit that it will assign an IP and then the router will give out internal ip addresses so that they can get online. The switch does not have this functionality.
Because the cox cable modem will only bind to one mac address (computer). You need to purchase a router, any router linksys, dlink, will do, get a wireless one so you can setup wifi as well. Plug your cox cable modem into the wan port on the router, plug your pc into one of the ethernet switch ports, you can use your web browser IE to login to the router and secure your wifi signal, power cycle your modem to make it bind to the new router. Most linksys dlink are programmed for a class c network, you could in theory put 254 devices, computers on your connection now.
You sure can. Start w/ the Comcast modem as long as it is NOT a USB type and hooks using a CAT-5 cable (regular network cable). Hook the comcast modem to the WAN port of the wireless router. On the back of the wireless router use the normal 1-4 extra LAN ports to hook other computers or the SD208 switch to it and other computers from there.
Word of advise if using Wireless Router, be sure to read manual and set a KEY for your network to secure it from unwanted outside use.
Is this the DSL router that comes from the ISP or is this one that you purchased for this purpose?
The problem would seem to be that you are probably only getting one IP address. If this router is from the ISP then you are probably only getting one IP address. If this the case you will need to either request another router that has the ability to act as a DHCP server. If this is not an option, then my solution would be to get another router/switch that will provide IP addressing. This would solve your problem.
However, with not knowing whether you are getting ip addresses on both computers this is just my best guess based on the information provided.
Absolutely. The router will have an uplink port. It will indicate on the back. Hook the modem from sat to the uplink and the other 2 computers to the other ports. make sure the computers are on DHCP (they should be defaulted to it) and they should auto connect
That is because most cabel internet providers only gives you one public IP. Please go to a Best Buy, Office Depot, Staples, Walmart, or Targer, and ask for a LinkSys Router. The router will do NAT (Network Address Translation) that will allow more than one PC share the single public IP. This will solve your problem and will cost an estimated $30.00. The router is simple to hook up, just plug the cabel from your modem into the Internet/WAN port on the router. And the two computers into any of the other ports. Be sure to unplug both cable modem and router then plug up the cable modem first, once the ready light is on, plug up 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.
