The password is case-sensitive so make sure you write it down carefully.

Thanks for the details. I wish i found your post earlier.

Wrt to unifi tv, M4 still didn’t support? Because i still couldn’t get unifi tv connected.

Thank you.


Any chance you could do a guide for maxis fibre? I’ve heard that you can only use these as AP instead of completely replacing the maxis fibre router. (which I intend to)
