I am trying to assign static IP address to my PC. I use zyxel wifi router and added my mac address for static ip assignment. Now my router has two separate bands 2.5Ghz and 5Ghz. Whenever I connect to 2.5Ghz band, my static ip is same as what was configured in the router. However when it is connected to 5Ghz wifi, it is different from what is configured. Now static IP should not dependent on Wifi Band as it is the same device connecting to same router.
