@Pankajuuuuu Not sure if you've read, but I've already done that.. 

  @HarutolistI am unsure why this is not functioning for you. But in my tests you can see it have resolved 

  @Pankajuuuuu A different test here, same bandwidth setting. I'm unsure why the download is bad but upload is somewhat stable

 
@Harutolist you should try setting the bandwidth 15 mbps lower than the plan i think this will help

As Asians, we always get an A+ 💀💀

  @Pankajuuuuu same thing happens.. i am gonna go nuts atp. I've set download to 285 and upload to 135, yet same thing happens

  @Harutolist  There is a stable firmware available in your region, which is the latest version I recommend installing it to check the performanceThere is no need to worry, as you can always downgrade if required

  @Pankajuuuuu i did that before this one... And had the same horrible results. I guess this router really has no SQM/AQM, and also, i think it doesn't work with high bandwidth, bcz no matter what i set it to, the ping is always bad when i enable qos:/

No, this router is equipped with a highly capable processor that can handle QoS throughput in the range of 800–900 Mbps without any issues.

  @Pankajuuuuu welp, now it's even worse.. i think the whole advertisment about the high bandwidth capability is rather.. a scam?? Idk, you have great results with small bandwidth, i have horrible results with high bandwidth 

  @Harutolist can you do a cloudflare speed test without qos and with qos and share ?
