Androids are connected but no Internet. Have restarted modem and restarted the Android phones, also set the Androids to forget the modem and then setup again, can connect to Wifi OK but persistent no Internet on 4 or 5 Androids. 2 x PC's are working fine on WiFi. also have wired connection to the modem OK.

Hi - a few questions - is this a new modem or an existing one and sudenly this has occurred? What version is it - V3 AC or V3 HP? Are the PCs linked to the 2.4Ghz SSID or the 5 Ghz SSID - what are the Androids linked to? If you Clear Data Cache and History on one of the Androids, does it connect to the Internet? When you look at the Android Wi-Fi Settings, in the IP address secton, does it show the Modem's Optus DNS Server Primary and Secondary IP Addresses? Do you get an error screen when you attempt to connect to the Internet or just no response?
You're correct it's DNS problem. It is a V3OP, It's been working about 9 months then a problem in the last few days. If I set the DNS on the Androids to 220.127.116.11 voila it works. To answer other question I only have 2.4 Ghz available (there's no 5Ghz option to select). The reason the PC's worked is I had DNS manually set to 18.104.22.168
The Optus modem shows Primary DNS as 22.214.171.124 and Secondary 126.96.36.199 - I guess they're not working. In the diagnostics it pings the Primary DNS server OK (Pass result).
I don't seem to have ability to change DNS server settings in the modem, I assume Optus have the controlling hand with that.
Thanks for you're prompt reply, certainly pointed me in the right direction.
