I have a hub at home, I use it to connect to broadband and then share this broadband among my PCs.
- Previously I made a home network for 2 PC and 1 laptop, all with windows xp professional, all join the same group, set one PC's internet connection to allow sharing, and all others can connect to internet through this shared connection or can do with their own connection.
- I didn't notice when it happened, others can only connect to internet through their own connection while the shared connection icon still showing at other's task bar.
- Now I bought a new laptop, I think it's time to fix the issue. the same winxp pro for all. I run the same setup wizard, set one PC's connection allow sharing. This time, even the shared connection icon not showing on other PC's task bar.
I remember long time ago, once I had network problem, I format the PCs and got things working on the new builds. But this time, all PCs are nearly new builds. Any idea where I did wrong?
1You really should just get a cheap router, it works so much better than trying to make a PC act as a router while it's doing other things. – David Schwartz – 2012-03-05T02:57:33.463
what other things a router can do? Basically I need fast connection with internet and with all PCs. Nothing else is needed. – Jenny – 2012-03-05T03:19:08.100
1A router can route and NAT traffic between the PCs and the Internet. A PC can do this too, but unless it's dedicated to the task, it does a pretty lousy job. – David Schwartz – 2012-03-05T03:20:34.590
@DavidSchwartz has it right. On the cheap end, some routers can be had for 20 USD or less. Better quality routers are still available for well under 100 USD. Only the high-end feature-laden ones will run any higher than 100 USD. Many routers in the 20-100 USD range also come with other features such as WiFi, NAS, and VoIP. Some of them will take custom firmwares which enable even more features like bandwidth monitoring and tighter access controls. – Iszi – 2012-03-05T04:06:17.510
ok, since you guys say so, I will buy a router. but still don't understand why my network suddenly stop working. – Jenny – 2012-03-05T04:30:57.090
If they can all make their own connections directly to the Internet, why don't you just let them do that? Why do you want them all to go through your one machine that's doing Internet Connection Sharing? – Spiff – 2012-03-05T06:35:29.617
Because my ISP only allow 1 connection per line. So, I use hub to get the connection and plugin all PC on the hub. When I bought 3rd PC, I got to know the ISP also limit hub connections up to 2. – Jenny – 2012-03-05T15:07:51.963
@Jenny: Ah, that's an unsavable configuration. For your link to your ISP to work, it must do DHCP. But for ICS to work, it must do DHCP. With only one broadcast domain and no way to configure around it, they will conflict. – David Schwartz – 2012-03-06T02:50:24.890
