I have Asus RT-N16, flushed with this firmware :Tomato Firmware v1.28.9054 MIPSR2-beta.
Recently my internet speed (25/2 Mbps) is very unstable.
Initially, I suspected the QOS setting:
I turned off the QOS and the internet speed went back to normal. After few days, I found the same issue - tested it via speedtest and the speed was indeed slowing down.
So, I turned on the QOS and the speed was back to normal - and it keeps coming back; I gotta to repeat the process by turning QOS on and off.
Have anyone experienced this issue before?
