I just bought USB Wireless Adapter but didn't know how to install it. I've tried using lsusb and lshw -C Network before and after plug the USB.

Here's the output of lsusb.

Before: 

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 5986:0543 Acer, Inc 
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After:

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 003: ID 5986:0543 Acer, Inc 
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 031: ID 0bda:f179 Realtek Semiconductor Corp. 
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

It seems the difference is Bus 003 Device 031: ID 0bda:f179 Realtek Semiconductor Corp. But the output of lshw -C Network is same.

Should I install realtek wireless driver? If so, how to check which realtek wireless driver I should install? Thanks.
