Q: 5G wifi linkspeed is slow (11Mbps)
I don't know this starts from when, and I'm not sure whether this is a problem of the router or of my mac, because those are the only two devices with 5G wifi hardware, so there's no way I could do cross-check.
It used to be very fast, I could transfer between my mac and my nas (attached with Gbps cable) at 100MB/s, at that time the autoconfigured linkspeed is 1300Mbps. Now the transfer rate is at max 3MB/s. What a big difference!
I've tried rebooting the router, rebooting the wifi, delete the wifi profile and reconnect, all sorts of basic operations. I'm not very familiar with wireless router engineering (not very familiar with telnet commands), so please help me with this. Is there anyway to locate the problem?
I am using a Macbook pro 13' 2015, the OS is el capitan 10.11.1. And the router is R6300v2 with the newest firmware (which is flashed very long time ago, long before any problem arises)
MacBook Pro with Retina display, OS X El Capitan (10.11.1)
