I replaced  with a different product. 

SOLVED! Go into your internets router, google the company you use for internet and default i.p and password if you dont know it, and once logged into it, have a look what the ip address is on the extender under devices or the like, then put that in your browser then you will get into your extender settings, change the very long password under settings for what you want it to be then apply, I had the same problem, this solved it, no need for the unnecessary tether app. You are welcome.

if you're using 5GHz the login & pass are: admin

 

if you're using 2.4GHz there is no password. 

Hi. I have faced exactly the same problems which I have installed and paired the WiFi extender with my router. When I key in my router password, it says incorrect password. I am sure it is the same password. Can you please advise? Thanks

@Yohan8888 google your routers brand and default password, or look on the bottom of your router

 

just your standard NZ vodafone router, just google what every brand you have and default password or look at back or bottom for a sticker
