Short version: What dual-band router has QoS to deal with "buffer bloat" problem? I think queuing algorithm is called "fq_codel" or something. Long version: My current router is Asus RT-N66U. I didn't have problem with stock firmware. But, after upgrading to the latest firmware this weekend, I'm experiencing "bufferbloat" problem. When I download a large file (eg. ISO file), I can't browse or send emails or anything, until the download is finished or terminated. Right now, I'm using my previous router TP-LINK TL-WDR4300 with DD-WRT. But, its 5GHz band is flaky, and it needs frequent reboot. The very reason why I replaced it in the first place. So, it's time for a new router. I'm looking at Asus or Linksys. Any recommendation based on what you have or what you've heard? -- William
