I have a problem with the TP-Link vx230v modem I purchased from AGL in December 2023, when I signed up for their 100/20 plan + home phone. I canceled my AGL account after 11 months and joined another ISP (MATE). I kept the AGL modem as it was not locked by AGL. I factory reset the modem, logged in via Firefox Browser with 192.168.1.1 and changed the username, password and other settings for my new ISP and saved. All is working well and my internet connection is great as well as my VoIP phone service.

My issue is: I have to factory reset the modem to be able to log in via my browser using 192.168.1.1.
I cannot log in without doing the factory reset. All I get when I enter 192.168.1.1 into my browser is an error which shows "Cannot connect". It's the same error message with 4 different browsers (Edge, Vivaldi, Brave and Firefox).

This is extremely annoying, especially to other users in my household who lose connection when ever I reset the modem. After the factory reset I can connect with 192.168.1.1 and the modem page displays asking for the password. It's frustrating because it also defaults to my original AGL username and password (in the Basic Internet section) which I have to change each time, to my new MATE id. Can anyone help? I have contacted TP-Link and all they do is give me a standard set of instruction, but none of them work.
I'd love a fix for this if possible. Many thanks for reading, Cheers.
