My work gave me a laptop. Our Network admin set the thing up for me. Added, IP addresses and DNS addresses. Got the whole deal up and running here at work. So I take it home and plug it into my router...nada. I have a cable modem and attached to that my router. Is there new IP and DNS setting I need to do at home too? |

Your home router is most likely set up to hand out dynamic IP addresses. Sounds like at work you have fixed IP addresses. So at home you'll most likely turn off the fixed IP address. BUT.. I've made assumptions about your setup so I might be wrong. My home router has a mixed mode for instance. It gives my home desktop a fixed IP so it can work as a network and print server and my other two laptops get dynamic IPs form the router |

what if I'd connect directly to my cable modem? My Xbox 360 works that way. |

Until you allow your laptop to request and get the IP and DNS info from your router (which acts as your DHCP server), it probably won't work. If you need to go back and forth, buy a $20 router for work as well, configure *it* with the static IP and DNS info, then connect your laptop to it at work. Hard to believe anyone is running a non DHCP network and surviving these days. Those were dark times in networking history. |

In network connections, create a new connection and set it to obtain Ip address automatically. That only works if you have admin rights on the box though. It will be the same no matter where you plug in. |

I run a non_DHCP network with close to 200 machines and I'm still alive. |

Your users must be better behaved then ours. We have too many developer types... We would have rogue people guessing at IP addresses all over the place and stepping all over each other... |

Yea, 85% of my users don't know what an IP address is let alone how to change it. |

One other thing to think about - some cable providers charge extra if you want to use more than one computer. You have to call them for a password for the modem to recognize the new computer.(and accept the additional charge to your bill) |

But if you want to hook up more then one computer you need a router. The router is the only connection to the cable modem. Cable company's will charge you extra if you want them to hook it up for you but that is unnecessary. |

Chinashop, I could stop by some day (assuming you are in the Falls) on my way home between Cedarburg and Muskego to take a look at it...I'm the closest thing to an IT manager at my place of employment (one of many hats). |

Depending on how your home router works you may be able to config the LAN side of the router with the same first three octets as the work LAN, then tell it to only lease the work IP to your MAC address, or to trust any IP from that MAC address. The issue you will probably run into is that a lot of routers won't route traffic from an IP they didn't serve. You can configure it to do so anyway though IF your ISP allows you to configure the router. Or buy a $20 router for work if they're ok with that. Get one WITHOUT wireless. If your company is still using static IP's they're probably also pretty particular about security. Wireless is a no-no in a secure environment. |

XP has an "Alternate configuration" ability where you can have DHCP enabled but have a static IP address that kicks in where no DHCP is found (ie at work). http://support.microsoft.com/kb/283676 you'll need to move the work configuration to the "alternate" page and set the "general" tab to "Obtain" for IP and DNS. |
