Installing and updating drivers
The most common reason for WiFi not working on Samsung R730 is the lack of the correct driver or a version conflict. This laptop model was often equipped with modules from different manufacturers, such as Atheros, Broadcom or Realtek.
To determine the exact device, open the Device Manager (command devmgmt.msc). Expand the "Network Adapters" tab. If you see a device with a yellow exclamation mark or the entry "Unknown Device," the driver is definitely not installed.
The best solution is to download the driver from the official Samsung support website, specifying the exact laptop model. However, since support for older models may be limited, you can use the hardware ID. Copy it from the device properties and enter it into a search engine to find the appropriate driver.
| Module manufacturer | Typical name in the system | Recommended action |
|---|---|---|
| Atheros | Atheros AR9285 Wireless Network Adapter | Download the driver from the Qualcomm/Atheros website |
| Broadcom | Broadcom 802.11n Network Adapter | Use the driver from Windows Update |
