I used theTether phone app to setup and it successfully connected to the internet. However, I was only able to log into WIFI on the phone with which I set it up. When I tried to connect to the internet on my other home devices, they all failed. The message states "Unable to Join Network. This network is operating on Wi-Fi channels in use by several other nearby networks".
I restarted router and modem but no success. Could the reason be that I used the same password for the 2.4 and 5G? What is preventing me from acessing the WiFi? Please help.
