Here's your solution to the only one arrow of wi-fi is blinking issue


long press your wi-fi network, an option will appear 'modify network' click this.
Go to advanced setting and change your Ipv4 address from 'static' to 'DHCP'.
After this also if your problem is not solved then contact to wi-fi owner.
