Deco P9 password not recognised by devices
Hi, new user here - managed to set up newtork of 3 P9 decos successfully - first is ethernet connected to existing Plusnet modem/router. The other 2 are plugged in around the house and are successfully linked to each other with steady white LEDs.
My Android phone has successfully logged in to the new network and getting brilliant Wifi throughout the house, but none of our other devices will connect. They all recognise the new Deco network and show a very strong signal, but when I try to connect, the password is not recognised. (Old Android phone, new Android phone, Microsoft Surface laptop, Older HP Laptop, Sony Bravia TV, and HP Desktop - none of them can connect.)
I've checked the password on the Deco App on my phone, and it is definitely the one I am trying to use.
I've checked that Fast Roaming is disabled (as recommended for older devices)
I've tried switching off the WiFi on my existing router but that doesn't help.
I've tried changing the Deco to an Access Point instead of a Router but that doesn't help.
Maybe there is a way to change the master password and try again, or reset the whole system?
Any suggestions welcome please, as this is very frustrating indeed!
