I don’t see how though as I use to have double the download speed on the ps4 with an old provider where the broadband was only 50-60mbps
now I’m on 500mbps I only get 20-30 and it’s closer to the ps4 then the old provider router
There are many WiFi standards, and each router (HUB) can use different ones depending on their specification:

One thing you could check/change, although sometimes not recommended, is the channel width on the 2.4Ghz band in your HUB settings.
I believe you can set it to 20/40, rather than 20.

Whilst you are in the HUB settings check the 'Connected Devices' section to see what speed your PS4 is connected to the HUB.
