I woke up this afternoon to a message stating that there was another computer on my network that was sharing the same IP address.
There was a long power outage while this computer was on (laptop). What caused this? |

I woke up this afternoon to a message stating that there was another computer on my network that was sharing the same IP address. There was a long power outage while this computer was on (laptop). What caused this? Unless you set up each computer on the network with a manual IP, they will all try to obtain the first one (192.168.1.100 on a Linksys, for example). In your case, the laptop lost the connection & another computer got it first when the power came on. If you want to fix the problem permanently set up a permanent manual IP for each computer. Start with the first hardwired computer; Start ––> Control Panel ––> Network Connections ––> Local Area Connection ––> Support ––> Details Write down your subnet mask (255.255.255.0) & your gateway (probably either 192.168.1.1 or 192.168.0.1), & your DNS servers. Go back to ––> General ––> Properties ––> Internet protocol ––> Use the following IP address for computer #1 (start with desktops connected with CAT5e); 192.168.1.110 (or 192.168.0.110 if your gateway has a "0" in it instead of a "1"). Then enter your subnet mask, gateway, & DNS servers. Same procedure for computer #2 (except you're going to assign it #111, etc); 192.168.1.111 Computers with automatic configurations will grab the lowest number available (192.168.1.101, 192.168.1.102, etc). By starting your computers at #110 it leaves #101 through #109 for any computers added to the system later (like wireless laptops) so you don't have a conflict (unless 10 people with automatic configurations log on to the network before you can reboot yours). Note: If you configure your wireless laptop with a manual IP & you try to use it on another network (friends house, etc) it won't work if that IP isn't available (so you would have to set it back to automatic or you would have to manually configure it for the new network. |
