The on-board Broadcom Wi-Fi (with external antenna) is far superior to
crappy dongles, of which I have a couple myself.
Cell 01, 70/70, is the wireless router in the same room, a few feet
away.
Cell 03, 37/70, is the wireless router in my front room, 25-30 feet
away, and straight-line through 4 walls. (Touch, sat next to WB, can't
"see" this router).
Code:
--------------------
$ sudo iwlist wlan0 scanning
wlan0 Scan completed :
Cell 01 - Address: 00:0E:2E:92:25:E2
Channel:1
Frequency:2.412 GHz (Channel 1)
Quality=70/70 Signal level=-25 dBm
Cell 03 - Address: 00:16:36:CB:70:33
Channel:6
Frequency:2.437 GHz (Channel 6)
Quality=37/70 Signal level=-73 dBm
