Admin password blocked turning on WiFi

[#1]

I usually use a LAN cable for the Internet but needed to switch on WiFi for a a freind. First I got notice saying it was an unstable connection, but then 'Help'  revealed PlusNet says it is OK to go ahead. I then had to put in an Admin password but when I try to do this it says I have to wait 4 mins 59 secs. If I do that though, I get the same message and am told login is blocked. So basically I want to know how to turn on the WiFi. I have a PlusNet Hub Two. Thank you

My thinking is the message was not a secure connection not unstable?

Does this help explain https://www.plus.net/help/hubgui/hub-warning/

Weird. I just tried logging in with an incorrect admin password three times (over Wi-Fi) and every time just got the message:

! Error - the admin password is incorrect

After then putting in the correct password I logged in as usual. No such message about needing to wait.

How many times did you try logging in? What browser are you using?
