I’m currently residing in an area where running a wired link to my PC isn’t feasible, so I’m using an ASUS PCE-AXE58BT WiFi 6E PCI-E expansion card instead. The main challenge has been the limited length of the antenna wires, which makes positioning crucial to avoid interference with my audio interface. I’ve explored some extension cables but have limited knowledge of networking and am unsure about suitable choices. Additionally, I’m worried whether using an extension cable might weaken my signal, especially since my internet connection isn’t strong. Any advice or recommendations would be greatly appreciated.

You’re looking for an RP-SMA extension cable, similar to those found on Amazon for $8 to $20 depending on the length: https://www.amazon.com/XRDS-RF-Antenna-E...B0B59DTTQ5. Regarding signal loss, the 3-foot wire you linked would cause roughly 0.774dB at 2.4 GHz, or about 17% loss. At 5 GHz it jumps to around 1.2dB, or 24%. This is just how antenna cables behave—any extra length means more signal drop. Adding that extra three feet might actually improve your antenna’s position, making the loss seem smaller if you can get a stronger initial signal.
