That is 44 Mbps and 84 Mbps respectively instead of 450 Mbps theoretical maximum. On the contrary my Intel 6300 WiFi card does 5.5 MB/s on the laptop-to-router-to-server copy and 10.5 MB/s on the server-to-router-to-laptop road. I would say that its sufficient for Internet browsing but using local LAN resources over NFS can be painful. Really far from theoretical single antenna 802.11n 150 Mbps transfer … its probably fault of the FreeBSD wireless stack. That is 23.2 Mbps and 20.8 Mbps respectively. laptop =WiFi=> router =LAN=> server 2.6 MB/s Still about 5 meters away from the router. The file copy from laptop using WiFi to LAN server attached directly to WiFi router was about 2.6 MB/s fast. server =LAN=> router =WiFi=> laptop 2.9 MB/s The file copy from LAN server attached directly to WiFi router to my laptop was about 2.9 MB/s fast. The results are not that bad but not great either. I next tested the performance of this simple single antenna Realtek chip using NFS large file transfer in thunar(1) file manager. One last step with DNS and we will test the connection with ping(8) command. Lets add LAYER 3 with IP address using dhclient(8) command.

Its now listed as rtwn0 as its supported by the rtwn(4) driver on FreeBSD. Ugen2.3: at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA) … and some more information from usbconfig(8) command. We will now attach Realtek RTL8188CUS chip and will check whats coming in dmesg(8) command. My ThinkPad W520 laptop already has Intel 6300 with 3×3 antennas and 802.11n standard WiFi card supported by iwn(4) driver. This is for 12.2-RELEASE version but it worked the same for 11.1-RELEASE 3 years ago. I will now show you how it works on FreeBSD. When connected it also gives subtle little dim light. Its also very small and almost does not stick out of the laptop. Its not very powerful as it comes with 1×1 antennas and 802.11n support – yes only single antenna. The Realtek company even got Taiwan Green Classics Award 2011 for their 802.11b/g/n 2.4GHz 1T1R WLAN Single Chip Controller (RTL8188CE/RTL8188CUS) on 2011 year when it was introduced.

Its used in many appliances and products but we are interested in its small USB WiFi version that is really small. This is where Realtek RTL8188CUS chip comes hand. When using FreeBSD on a new laptop you sometimes find out that the WiFi chip that it came with is not supported … or not yet supported in RELEASE version and support exists in CURRENT development version that you do not want to use.
