My main concern was the range of network performance that I was getting when the laptop was right in front of the access point. As you can see bandwith varied greatly. In addition, I recently purchased an ASUS RT-AC66U Dual-band Gigabit router. What is weird to me is that even though the 5Ghz radio is enabled on the router with various channels to use, ifconfig complains about not seeing channels above 13. Also, when specifically setting the router channel to 11, ifconfig reports that channel 1 is being used. I am not sure on what is going on. Is this normal? wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 ether 00:17:c4:ef:fe:1e inet 192.168.15.228 netmask 0xffffff00 broadcast 192.168.15.255 nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> media: IEEE 802.11 Wireless Ethernet MCS mode 11ng status: associated ssid datdude channel 1 (2412 MHz 11g ht/40+) bssid 10:bf:48:d9:1e:a0 regdomain FCC country US indoor ecm authmode WPA2/802.11i privacy ON deftxkey UNDEF AES-CCM 2:128-bit txpower 30 bmiss 7 scanvalid 60 protmode CTS ampdulimit 64k ampdudensity 8 shortgi wme burst roaming MANUAL
