Why does my PC keep losing its IP address?
Let us first rectify the cause of the problem, it might be due to a change in network, or problem with the DHCP Server of your modem, or if your router is slow or unreachable. While one of the silly reason can also be network cable not being plugged in.

What happens if DHCP client fails to obtain IP address?
If not, the server responds to the DHCPRequest with a NACK packet. If the client sending the DHCPRequest is requesting an address that appears to be on the same subnet but was actually assigned with a different subnet mask, the DHCP server will remain silent and the client will fail to obtain a valid IP address for the new subnet.
Can a DHCP client get a different IP address?
If the client sending the DHCPRequest is requesting an address that appears to be on the same subnet but was actually assigned with a different subnet mask, the DHCP server will remain silent and the client will fail to obtain a valid IP address for the new subnet.
What happens if the DHCP address is not on the same subnet?
If it originated from the local segment, the DHCP server compares the requested address to the IP address and subnet mask belonging to the local interface that received the request. If the address appears to be on the same subnet, the DHCP server will remain silent even if the address isn’t in the range of its pool of addresses.
Can a client still use the same IP address?
The client will attempt to verify that it can still use the same address by sending a DHCPRequest packet, populating the DHCP Option Field “DHCP Requested Address” with the previously assigned IP address. If the DHCP server remains silent, the client assumes the previous address is still valid and keeps it.
