is it set to "obtain an IP address automatically"?
Yes.
check dhcp settings on router.. maybe reset or switch to static
I should try these even though there is one working computer?
Your laptop is configured to get its IP v4 settings automatically from a DHCP server, but apparently those settings are not getting set. When the network adapter can't get settings from a DHCP server after a few seconds, Windows configures it with the autoconfiguration IP address 169.254.x.x.
I wonder if it would help if you would bypass DHCP by setting the IP v4 settings manually. To do so, you will need to know what the correct IP address, subnet mask, default gateway and DNS are to communicate properly. You can obtain this information by running the ipconfig /all command on another computer on the same network that can still connect to the internet. The subnet mask, default gateway and DNS addresses should match exactly, but the IP address should be different, as follows:
If the subnet mask, is 255.255.255.0, the IP address should be set the same, up until the last period. Following the period, use a number between 1 and 254 that is not already in use on your network. For example, don't use the address listed as the default gateway.
I am a little confused , on my working computer the ip is nothing like the subnet. You want me to make the new ip and new subnet similar and forget the ip from the working computer ( subnet 255.255.240.0, ip 255.255.240.1, see below)
I tried doing this and it didn't work
"255 is not a valid entry, Please specify a value between 1 and 223" (by the ip address line).
