Asus RT AX 57 router Fibre 65

[Sam200me1]

Can I use this router ASUS Rt Ax 57 instead of my old talktalk router, which I have had for over 5 years. This is because I have problems with using multiple devices and speed lags in spite of having Wi-Fi extenders in the house. Reluctant to move to full fibre as wanted to keep home phone number. 
If I can use it instead, how would I set it up? 
thank you

According to @Divsec above, you need a modem in addition, to use that ASUS router in a pre-Full Fibre connection.

Even though the Wifi Hub 2 has a modem in it, the modem in it, can't be isolated to use it with that ASUS.

So I don't think you can use that ASUS router with a pre-Full Fibre connection. I think you can use it on its own with a Full Fibre connection.

Thank you so much for that. I haven’t bought the ASU’s router yet as I wasn’t sure it would work. Could I still add this as well as the Wi-Fi hub? 
thank you

I think it works on both, Full Fibre and pre-Full Fibre, @Sam200me1 .

Since you are not ready for full fibre, you can connect from the Master BT socket to the Broadband socket on the far left on the back of the WIFI HUB 2. And it might work better than your older router.

Aren't you going to use your ASUS router for now?

thanks I decided to get a second hand talktalk Wi-Fi hub 2 as I thought that would be better than my current probably over 5 year old router!  Now wondering if that only for full fibre? 
thanks again

thank you - I’ve bought a second hand talktalk Wi-Fi hub 2 router but not sure if this will work better? Is this hub only for full fibre - and needing a fibre connection box? 
I can’t go onto full fibre yet as my contract end date is a way off🙁

You can still upgrade to Full Fibre and keep your 'home phone number'.

But you might not get that much help from TalkTalk to configure your non-TalkTalk router.

Hi @Sam200me1 a quick check suggests the ASUS is a router only so the modem in your tt device would still be needed.

What model is your existing tt device?
