Third party router recommendation for guest WiFi

[Sonic25]

I've just renewed my Sky Gigafast contract for another 2 years and I'm looking for the correct type/brand of third party router to replace my hub (model SR203,

Firmware Version7.04.0208.R).

I want to add a guest WiFi for IOT devices and understand I cannot with my current router - and possibly any Sky router/hub? 

Can anyone recommend a router or direct me to where I can get more info on exactly this please. 
Thank you

Any router that can connect to the ONT and authenticate using IPv6 PD.

Asus routers are good for this but there are plenty others that you can get.

Ok thank you for giving me something to start on, I'll go look for one. 👍🏻

I'm assuming any modern router that supports WiFi 7 will authenticate using IPv6 PD?

Due to its good reviews I'm considering the 

GL.iNet GL-BE9300 Flint 3 Wi-Fi 7 Router Tri-Band 6 GHz 9 Gbps 5x2.5G VPN

It looks like that router doesnt specifically support DHCP Option 61 which is a legacy requirement for Sky lines, most Openreach FTTP lines now support IPv6 PD which I mentioned earlier. So short answer yes it'll likely work unless your in that small group of Openreach lines that dont support IPv6 PD.

Understood, I'll keep looking. Thanks
