Hy ,i had a problem with my network adapter not getting the ipv4 ip address from my router every time i closed my computer with my network adapter disabled ,after opening my pc if i would re-enable my adapter i would find a IANA ip present in ipv4 instead of my routers address (i checked the address and it belonged to iana's official address blocks but i dont have it now ) .It didnt matter if it was the wifi adapter or lan ,the same thing was happening for both adapters.So the only way i could get my routers ipv4 address was if i had my adapter enabled before shutdown not disabled .I didnt have this problem with any of my other laptops or phones or etc connected to my network. I Hope i explained the issue i had clearly enough.

 

The problem disappeared completely after i restored my system from a backup i did a month or two ago ,and whats weird is that i think (but dont know for sure) that i had the problem at the time i did the backup too so i dont know how it got solved .

 

Anyway, i want to ask what could have made my adapter not get the correct ipv4 address and get a Iana ip address instead ? And what could have solved it? If someone has any ideas i appreciate it.

You get the apipa ip address 169.254.x.x when you are configured to contact a dhcp server but you are unable to contact one.  This can be caused by bad drivers, hardware failure, firewalls and malware.
