Bluetooth
Realtek supplies the Bluetooth radios in many mainstream laptops, budget desktops, and inexpensive USB dongles. The part is usually paired with a Realtek Wi-Fi controller on the same module, and the validated driver tends to reach you through the PC or motherboard maker rather than as a universal Realtek download.

This is a widely used onboard audio codec family for consumer motherboards and laptops, driving analog jacks and internal speakers on supported systems. It reports itself under "Sound, video and game controllers" and may pair with a vendor control panel for jack retasking and equalization.

This is the multi-gig sibling of Realtek's gigabit part, found on newer motherboards that offer a 2.5 Gbps wired port. It falls back cleanly to 1 Gbps on older switches, so reaching its full rate requires 2.5 Gbps-capable networking gear and adequate cabling end to end.

This is the single most common wired-LAN controller in consumer computing, integrated on a huge range of desktop boards and laptops as the standard gigabit port. It handles link negotiation up to 1 Gbps along with the usual offload and power-saving features.

Realtek publishes PCIe controller software covering multiple FE, GbE, 2.5GbE, 5G, and 10G families. The exact controller, host product, Windows release, cable, and switch determine applicability and negotiated speed.

Realtek supplies multiple PCIe and USB card-reader controller generations used in some PCs. The Realtek name alone is insufficient: match the hardware ID, PC model, supported operating system, and package's compatible-system list.

Realtek USB Audio covers the codec inside many USB headsets, speaker bars, and small audio dongles that connect over a USB port rather than an analog jack. Windows can usually run these devices with its built-in class driver the moment they are plugged in, so the Realtek package mainly matters when a device exposes extra controls.

This controller powers a large share of USB dongles and dock-based Ethernet ports rather than a soldered motherboard NIC. Because it rides on a USB or Thunderbolt link, its dependability depends partly on the host port and, on a dock, the dock's own firmware and USB stack.

This retained route name is a search label, not a Realtek-wide package claim. OEM audio stacks can add software endpoints under different names and from different companion vendors.

Realtek wireless LAN adapters appear in many budget and mainstream laptops and in a large number of USB Wi-Fi dongles. The driver governs the same roaming and power behavior as any wireless part, and on a laptop the OEM build tuned for that model tends to be steadier than a generic one.
