Solved 169.254.x.y, 2 laptops, same home network

Specs: Windows 7
I have started having random occurrences of ip address of 169.254.x.y being assigned to 2 laptops connected wirelessly. Never occurs while in use, but rather in standby. We use the windows logo key and L key to place in standby. Sometimes it can be resolved with a simple connect and recoonect to the network. Other times it takes awhile and the laptop will gain a proper addres on its own. Other times nothing will straighten it out except putting it back in standby and trying again later and it could come out of standby fine and work. I have a Dish Network modem and a Netgear router. Since the problem occurs with 2 laptops, I suspect a modem or router issue. Any help greatly appreciated.

Check what the lease time is on your DHCP server. Once a device has acquired an address it shouldn't lose it withing that time period.

According to Network Connection Details the lease is for 24 hours. Just now it worked and assigned a new 24 hr period qhen I checked it. Wondering if the assignment doesn't always work, for example after lease time expires. I am not certain that 169.254.x.y only occurs when lease has expired. I have a printer, 2 cell phones, a Dish Hopper and the router on the same network. The other devices don't experience the disconnect issue. Only the laptops.

✔ Best Answer
169.254.x.y range is a private IP address that Windows allocates when it cannot find a DHCP server and there is no static address assigned

It probably does occur when the DHCP lease expires and for some reason cannot renew it.

As both these laptops are wireless i would start looking at your wireless connectivity.
