@sanchit . The VR1600 has to be cabled to the other router.
You may still get a small benefit in moving the VX220 within the room, when it comes to position the extender on ground floor.
Hi @sanchit . Your photos did not get attached.
What type of NBN connection box do you have in your bedroom?
The Sagemcom 5G modem is normally used on 5G wireless broadband services, not cabled NBN connections. If you stop using 5G wireless, TPG want the Sagemcom sent back.
Is the Sagemcom connected to the NBN connection box?
The Sagemcom could be moved to another position on first floor, closer to centre of house. Its wifi might then reach ground floor better.
To use the VR1600, it has to be connected by CAT6 cable to Sagemcom.
Login to VR1600 admin, change its LAN ip address to 192.168.1.2, disable DHCP and NAT and Save.
Connect VR1600 LAN port to Sagemcom LAN port.

Connect VR1600 LAN port to VX220 LAN port. You can leave the VR1600 wifi network names as is or change them to be same as VX220. The 2.4GHz network channel number should be different on each router; Use 1 and 6, or 1 and 11, or 6 and 11 (to reduce interference).
It might be easier to use an extender placed on ground floor where it gets good wifi signal from VX220 upstairs.
