Wps Not Showing

i want to use pixie dust and reaver attack against a wifi router but when i try to scan wps enabled devices using "wash -i mon0" command in linux it does'nt shows up the target router like its not wps enabled but i know it is because in my 2 android phones it is showing wps enable alongwith the windows 10 in my pc and i also know that linux is not broken because it is showing other networks with wps enabled. i have also checked with wifite but it is not showing wps. so is it a kali linux problem or its the problem with my router.
