Little issue with my router. My through speed when connected to the router is only 193Mbps, yet when i plug the ethernet direct to my pc, i get 920Mbps.

Hope some one has some ideas please>

Additional information needed for clarity:
What is the full model number of your router? Look on the nameplate on the device.
What is the full brand name and model number of your modem/ONT connected upstream of your router? Look on the nameplate on the device.
When your say your throughput when connected to the router, I presume you are talking about a Wi-Fi connection?
If yes, what band are you connected to? The 2.4 GHz band or the 5 GHz band?
What device, brand name and model number, are you connected with when you measure your throughput?
What application are you using to measure throughput? Recommend using the Ookla stand alone application that does not use a web address or web browser. Available from the playstores.
The router (data plate uploaded) is connected to the modem (data plate uploaded) via a Cat8 cable. Yes I’m measuring internet speed using Ookla. I figured no point I’m measuring the WiFi till the hardwired connection is sorted.
Your Sagemcom Model F3896LG-VMB is a combination modem/router.Specifically, how it is configured is critical to the configuration and functionality of your R8000 Wi-Fi router.
Are the throughput problems you are experiencing a new situation or are you just now configuring this network?
You need to find out how your Sagemcom device is configured and then decide on how you want to configure your R8000. You may have to find a manual for instructions on your Sagemcom device.
If your Sagemcom device has a bridge mode that effectively disables the router, that would most likely be the best option to pursue.
For your specific issue, there will be some more info needed.
The change in speeds that you seem to have references, has less to do with AP mode (though a double NAT is never good, ideally the modem/router combo would have an option for a transparent bridge or an IP passthrough mode where it will allow the R8000 to function in its router mode without a double NAT. though that is a separate issue.
For your throughput issue there are multiple causes.
Since it is an 802.11ac router, odds are that most of your client devices are 1-2 stream devices, at 80MHz channel width and 256QAM, thus under ideal conditions, your single stream devices will be at a PHY rate of 433.3Mbps and your 2 stream devices will be at a PHY rate of 866.7Mbps. At a PHY rate of 866.7Mbps, most devices in the same room as the AP will top out at a real world speed of around 650Mbps, and if in another room, speeds can be more in the 450Mbps range.
With a 433.3Mbps PHY rate, often you will get around 290Mbps when in the same room.
On the 2.4GHz band, you will get around 100-110Mbps on a 2 stream device using 20Mhz channel width.
If you want gigabit speeds over WiFi with modern 2 stream devices, you are effectively stuck with upgrading to 802.11ax, where a 2 stream connection 2400Mbps PHY rate, will give you around 1.8Gbps real worth throughput when in the same room, though depending on the client device, you may need to upgrade the WiFi adapter (often a $15-$20 part).
Anyway, to better narrow things down,check the PHY rate of the client devices connected to the R8000.
