Realtek Rtl8188cu Wireless Lan 80211n Usb 20 Network Adapter Link
Extremely small form factor, typically around 1.8 cm x 1.5 cm x 0.6 cm.
The RTL8188CU is famous for dropping connections on Linux. Do not use the default rtl8192cu driver that comes with the kernel—it is broken.
The 2.4GHz frequency typically offers better range and signal penetration through walls compared to 5GHz. Extremely small form factor, typically around 1
This is a classic driver conflict error. To fix this, completely uninstall the current device from the Device Manager, check the box for "Delete the driver software for this device," unplug the dongle, restart the PC, and install the standalone driver manually using the Microsoft Catalog link.
