NBN connection problem

[moon]

I am using NBN Internet in my house. But in these days, the Internet is not good. I tried to use iPhone to connect WiFi, but it failed. However, when I change to other brand of mobile phone, I can connect WiFi successfully. Why? How can I fix this problem?

Hi @moon Firstly, have you restarted the modem and tried resetting network settings on the iPhone? Are the 2.4 and 5 ghz lights both lit on the modem? Which exact model iPhone are you using?

Thanks for the info, have you tried resetting the phone's network settings and rebooting your modem?
