Q: Can I use the Realtek 8188GU with multiple devices?

Supported OS: Windows 7, 8, 8.1, 10, and 11 (mostly 64-bit versions).

  1. Disable Bluetooth Coexistence (Windows): If your PC has Bluetooth, it interferes with 2.4GHz Wi-Fi. In the Realtek configuration utility, find "Bluetooth Coexistence Mode" and set to "Disable" (Note: this may cause Bluetooth audio stuttering).
  2. Change your USB Port: The 8188GU generates heat. Plug it into a USB 2.0 port (not USB 3.0) to reduce thermal throttling. Alternatively, use a 1-meter USB extension cable to move the dongle away from the USB 3.0 port's EM interference.
  3. Router Settings: Force your router to use 802.11n only (disable b/g), set channel width to 20MHz (40MHz causes interference in crowded apartments), and use WPA2-AES (not TKIP).
