Qos and traffic meter is disable
用usb 手指 realtek chipset 300mbps 1t2r
我發現用nas function 去到100， 點解會咁
用lan 線係去到200， wan to lan througput沒問題
Mode up to 300mbps
EDIT The same problem exists with a Netgear R6250 router. I had to disable WMM and also select "Enable QoS" (after removing all the priority rules) in settings for the same fix.
With this router I am able to connect all the clients, with laptop getting 150 Mb/s link speed and 100+ Mbs download speeds on ipv4 and ipv6, and Nexus 7 falling back to Wireless G (I think) with 54 Mb/s link speed.
