Debian system has support for popular USB WiFi drivers. Many USB WiFi modules are plug and play with our system. Here is a list of models we tested;
Number Model
1 RTL8188CUS 802.11n WLAN Adapter
2 RT2070 Wireless Adapter
3 RT2870/RT3070 Wireless Adapter
4 RTL8192CU Wireless Adapter
5 mi WiFi mt7601
But still not test RTL8192EU wireless adapter,if you want to use it you need to modify the kernel.
