| Issue | Likely Cause | Solution | |-------|--------------|----------| | Frequent disconnects on Linux | Default rtl8192cu driver power saving | Install lwfinger/keenerd driver; add options 8192cu rtw_power_mgnt=0 rtw_enusbss=0 to /etc/modprobe.d/rtl8192cu.conf | | Low speed (only 54 Mbps instead of 150 Mbps) | Not connecting to an 802.11n network, or USB 1.1 fallback | Force 802.11n only on router; ensure USB port is 2.0 or 3.0 (backward compatible) | | Adapter not detected on Windows 11 | Driver signature enforcement | Disable driver signature enforcement temporarily (Shift+Restart → Troubleshoot → Startup Settings) or use a signed driver from 2020+ (Edimax) | | Monitor mode not working | Default drivers block injection | Use aircrack-ng's rtl8188eus driver fork (works on CU with minor edits) | | Overheating | High TX power + poor ventilation | Add a heatsink or limit TX power: iwconfig wlan0 txpower 15dBm |
