Do you think it worth to change to new TP Link Archer BE230 (BE3600) as I haven't setup this WiFi 7 fibre router yet.
I think it pointless to do it because all devices are all WiFi 6, none of them all on WiFi 7 yet. Might keep the wifi 7 in the spare cupboard for now for future.
If you do not have anything WiFi 7, you will not benefit from MLO (Multi-Link Operation) which uses all radios at the same time for increased throughput.
Saying that, your vx230v is AX1800, and the BE230 is BE3600.
So:
at 5 GHz, your vx230v maxes out at 1201 Mbps and the BE230 maxes out at 2882 Mbps
at 2.4 GHz, your vx230v maxes out at 574 Mbps, and the BE230 maxes out at 688 Mbps.
The BE230 has a 2.5 Gbps WAN port which matches your 2.5 Gbps ONT, which may allow you to get closer to the 1000/115 service you are paying for.
Your 1 Gbps WAN on your vx230v may be hardware throttling the full throughput of the connection, which you would only be able to tell by using the 2.5 Gbps LAN port connected to a device that supports 2.5 Gbps or greater.
You will not notice this difference over Wifi though as your A54 is only WiFi 6.
