Router recommendations

[mrmortar]

I'm thinking about replacing my BT Home Hub 2 with something more customizable. My budget is around £75, and my broadband package offers 150 Mbps.

I'm looking for features like a guest network to isolate IoT devices, built-in VPN support (preferably WireGuard), ad blocking (AdGuard), the ability to use OpenWRT, and overall reliability.

So far, I've been considering the ASUS RT-AX53U and the GL.iNet Flint GL-AX1800.

I'll keep the BT router as a backup if I ever need to plug it back in for the sake of troubleshooting.

Any thoughts or recommendations would be appreciated!

Just be aware that if you are on Digital Voice, (or will end up on DV), you need the Home Hub as it is a proprietary version of the standard VoIP.

Other than that, everyone has their favourite.  Personally, I'm a Draytek fan but a lot would disagree with me.

Is digital voice as having a phone connected to the router rather than the old PSTN phone system?

(Not bothered about having any phone line as do it all via the mobile these days)
