ok, jeremyp77.
I believe this is your current config:
TP(opennetbox) ---> ONT ---> Your ISP Router ----> Asus AC56.
This means there is nothing wrong with your ISP Router and ISP Service. Is just you do the wrong configuration on the Asus AC56.
I Try and see if I can give you step by step to set up Asus AC56.
1) Connect wirelessly to your Asus AC56.
2) Once connected, go to your internet browser(Try to use Chrome) and enter "http://192.168.1.1/"
3) a "User" and "Password" will pop up. Enter "admin" for both section
4) Now you should be in the
Asus Ac56 Web menu. Double check and see if it is
Asus ac56
5) Go to Administration tab and change your mode to "AP Mode" or "Repeater mode"
Refer the image below(note: this is my other Asus router so there may be slight differences but most asus router share the same layout.)
6) Depending on how you want to connect;
6a) if you want to connect via wireless bridge like this:
TP --wired--> ONT --wired--> ISP Router ~~wireless~~> Asus AC56 ~~wireless~~> Your PC/devices
Choose "
Repeater mode"
You will need to point to your existing SSID(your ISP Router WIFI) and then set a new SSID(On the Asus AC56).
6b) if you want to connect via Wired:
TP --wired--> Ont --wired --> ISP Router --wired--> Asus ac56 ~~wireless~~> your PC/devices
Choose "
AP Mode"
this is a lot easier and you will get better speeds. Just set your own SSID(for the Asus ac56) and you are done.
Make sure Channels are different and it is best to have different SSID names.
eg: hamster and hamster_asus.
