Wireless getting invalid IP

My laptop’s wireless was working fine few days before. I went to a friends place where 2 routers were working. I tried to connect my laptop with 1 router but it got wrong IP 169.xx.xx.xx. since then it is not connecting with any router even with my own home’s router and show invalid IP. While DHCP of my router is working fine because when i connect my laptop through a LAN cable it gets a valid IP of 192.168.xx.xx. I’ve tried many things like i uninstalled my wireless connection, restarted my laptop tried different things but not working. Is it possible to clear wireless history like i uninstalled wireless connection 7 times and now it is showing Wireless Network Connection 8. Please can anyone provide me solution.
