    obvious things could be the network settings? MAybe it's set up for static IP addr?

      Have you tried slapping the laptop a few times? What about whispering curses into the ethernet port? Seriously other than the net properties and verifying that the actual hardware is good (i.e. the ethernet card or wireless card actually function) I'm out of ideas. At least for any that would be even remotely constructive.

        I have my work computer at home and it will not even recognize any wireless networks in the area while my home laptop sees three including our own. I tried plugging in the computer directly to an ethernet cable and it still can't find the network. Tried researching online and not seeing anything new to try. Any ideas?

        I've seen instances where network is using different encryption standard from PC, but that shouldn't cause problems until network identified! Still if you are stuck it might be worth checking.

          In device manager, are the NIC's healthy? No, yellow (!) If this stuff is on mother board, is it enabled in bios?

            In Windows, if you have more than one device in Network Connections in Control Panel, the information in this page[^] may be helpful. Changing the metrics helped me solve a (kinda) similar problem last week.

              Did you try running ipconfig to see what it says? Also, are you running Vista?

                is there any sort of a firewall you can see installed - Im assuming that since the computer does work at work its not the NIC - so maybe a firewall is being very restrictive about the address ranges it can see... still, I'd expect you to be able to 'see' a network .. unless there's a wild discrepancy in your home network frequency eg 802.11g and the machine only has a card that will work on an 802.11a network sorry, not much help 'g'

                  If this is Windows Vista then, In "Network Sharing Center" turn "On" the Network Discovery. I know this is funny, but see if the wifi-catcher switch is On. :-D Some Laptop come with Wifi/Bluetooth On/Off switch. Sometimes we forgot to check silly things.

                    Download NetStumbler and install it. If it picks up any WAPs then you know the problem is with Windows. If it doesn't then try to remove and re-install the wireless NIC. Maybe a bad driver was downloaded from Microsoft's automted update. FYI - sometimes the wireless NIC is not compatible with NetStumbler but I have only seen it once. :)

                      How old is the work computer? It may be that it only supports 802.11b and not the newer g or a standards. 802.11b and g use the 2.4GHz radio band, but unless the AP is configured in 'mixed' mode, 802.11b radios (11Mbps) can't use it. If there are 802.11b radios associated, the whole thing slows down to 11Mbps to accommodate them. 802.11a uses the 5GHz radio band; if the AP only supports that, b/g radios won't see it and vice versa. It's possible to configure a combined a/b/g radio to only scan one band or the other, so even if the radio supports both bands it may only see APs broadcasting in one band. If you post the model number of the laptop's WiFi card and the access point or router that acts as the wireless network's base station, it may be possible to help. As for wired ethernet - check that both ends of the cable are connected, try a different cable to rule out damage, ensure that the computer isn't configured for a specific speed or duplex setting. Auto-negotiation of speed and duplex usually works but can go into loops where it's either continually negotiating or the two ends think they've negotiated different options. 100Mbps/half duplex is the safe setting, and typically more than fast enough when communicating with a wireless network or the Internet. In addition, my Dell Latitude D820 defaults to disabling the ethernet port when running on battery power. Perhaps yours is the same? If it's a Dell, check the QuickSet utility, or plug in the AC adapter.

                        I will second the suggestion to try netstumbler. Are the wireless card and the ethernet card "enabled"? Have you verified that the wireless card / dongle / ?? is installed and recognised correctly? i.e. didn't become loose in moving. This does not sound like your problem, but occassionally I have had problems with not picking up a new IP automatically. I have had to force the IP by setting a fixed IP/gateway/dns on the new network. After that I can return to DHCP and all is well. Was the wireless card accidently turned off? (I have done that and it is embarrassing to search for the problem for hours and then find the switch is off)
