Hi I have good NBN wired access with this modem, but variable wireless NBN access.  My Pixel 2 running Android 9 can connect wirelessly to the LAN and internet, but my other devices running earlier Android versions can't. They can connect to the LAN but can't get internet access.  I have done a factory reset on the modem, (and restart on the other devices) but hasn't helped. It seems like other devices can connect to the LAN but are filtered/blocked from accessing the interenet. Is there a setting/filter/white list I need to change or add to? Any ideas anybody? Thank you in advance. ... View more
