My Controller Drops Out If I Sit More Than Two Metres From The Console

That range is genuinely too short, so do not accept it. A healthy DualSense should hold a stable connection across a normal living room, which is roughly eight to ten metres with line of sight. Falling apart at two and a half means the signal is being attenuated or drowned out, and both causes are usually at your end rather than in the controller.

The first and most common is where the console sits. The radio antenna is inside the console and it is directional in practice. A console inside a closed TV cabinet, behind a glass door, on a metal shelf, or with a soundbar or games stacked in front of it loses an enormous amount of signal, far more than people expect. Glass and metal are both effective at blocking 2.4GHz. Simply pulling the console forward to the front edge of the shelf, with nothing in front of it, frequently doubles usable range on its own and costs nothing.

The second is the 2.4GHz band being crowded. Bluetooth shares that band with 2.4GHz Wi-Fi, microwaves, cordless phones, baby monitors, smart plugs and USB 3 ports. If your router sits right next to the console and is broadcasting on 2.4GHz, it is competing directly. Moving the router a metre or two away, or shifting its 2.4GHz channel, often transforms range. Devices connected to the console's own USB ports matter too: a USB 3 hub or external drive next to it raises the noise floor measurably.

Work through the positioning and interference steps first, because they are free. Only if range is still short with the console in clear air and the router moved away does the controller's own radio become a suspect, and at that point a pin reset and re-pair is worth trying before you consider a warranty claim.
