i just upgraded my home unifi from 30mbps to 100mbps

the technician came and change my router

right after that, my samsung galaxy A3 unable to connect to my home wifi

i have tried many times to key in the password but it just won't connect

screen keep on showing "incorrect password"

but i have no problem connecting wifi in other places except my own home

my other samsung hp (S5 model) have no issue conneting to the wifi

any sifu here can help me out

thanks

Your prob seems complicated.
U mean only your s5 can connect home wifi while other devices can't?

Try use WPS button

thanks...yup problem solved

its the wps button

S5 can connect to wifi but not A3 at first
