Hi guys,

I'm trying to use a hub to connect two pcs to a cable modem. One of the pc's using win2k and is connecting fine, the other one using XP home edition and it is not connecting at all. The IP I got is 169.254. (APIPA) I tried connecting it directly it still not getting IP address. I reinstalled winxp and still have the same issue. of course I test the cable which is is connected to the modem on the other machine and it work fine. Also I do not use the hub when I try to connect with XP anymore. This pc was working before. Also I could not see any of the two pc's on the other machine. I tried installing small network, and all other network settings wizards in XP and it simply does not work. releasing the adaptor and renewing it (repair) does not work. It bring back the same IP 169.254
The weired thing when I take this pc to work (it is HP Pavilion laptop) it connect to the network fine. My ISP is road runner. Please do not advise to contact them, I already did that.

Hi,

Silly question perhaps, but your ISP WILL allocate you two IP addresses wont it?

Often people have to pay extra for that!?

Cheers,
Tim.

Hi, if you haven't paid for two ip's from RR you won't be able to connect via a hub, you will have to use a router.

Even if this is the sitution I'm still not able to connect directly from the XP machine. (without hub).

Some ISPs (don't know for sure about RoadRunner) determine which computeres are authorized to connect to the network by registering their MAC address. Since you probably had the other computer hooked up originally, or used that computer to originally connect to RoadRunner, the MAC address of that computer was recorded. Any computer with a different MAC address will not connect.
Also most ISPs do not support home networks. This doesn't mean you can't set one up. You just need to install arouter and use Network Address Translation (NAT) IP addresses for your home network.
Usually, routers will let you "clone" a MAC address (using the MAC address from the first computer to connect), so the router will be recognized by the ISP. They then will not know whether you have 1, 2, or 100 computers connected to the router.
Also, as you found out, if you mention multiple connected computers, they won't even try to help you.
Good Luck!
