I have just done it and got a message that the password would be changed on my router, if the router is not on then change it yourself, my router is not a normal plusnet supplied router, so I had to change it on my router manually, it worked fine.
This is the message i got after I changed the password.
Your password has changed - this is effective immediately.
You'll need to update the password for your:
Broadband router
Email application
Webspace
If your router is connected to the Internet now, the password it uses will be updated automatically, you may lose connection for a few seconds while this happens.
If your router is not connected, you'll need to update the stored password yourself, if you're not sure how to do this, take a look at our Router guides or give us a call.
I meant to do this months ago to be honest as my password is very easy to guess, so seeing your post got me to do it, thanks
