The RTL8188EU is a single-stream (1T1R) 802.11n chipset with a maximum theoretical speed of 150 Mbps. Real-world speeds are often lower due to distance, interference, and the USB 2.0 interface's limitations. For significantly better performance, consider upgrading to a newer 802.11ac or Wi-Fi 6 adapter.
The default Windows drivers do not support monitor mode. However, if you are using Linux for penetration testing or network auditing, installing the community-modified GitHub drivers (like the one by LWFinger mentioned above) will enable monitor mode and packet injection.
Open Device Manager, right-click the adapter, go to Properties , click the Power Management tab, and uncheck "Allow the computer to turn off this device to save power." Additionally, try changing your home router's 2.4 GHz channel to 1, 6, or 11. Issue 3: Missing Driver Error After Windows Updates sudo apt install linux-headers-$(uname -r) # Re-run the
