Overview

I'm tired of massive delay (500-1000 ms pings) while uploading large files. QoS helps some, but a significant portion remains due to bufferbloat (100-150ms). This leads to delay in VoIP calls and generally sluggish web browsing while uploading.

The new Codel algorithm in OpenWRT / Attitude Adjustment should help a lot. The results below show only ~5-6ms of added latency during uploads (i.e. 14ms vs 500+ms before!). Insane.

These instructions are for the TP-Link TL-WDR4300, because I got a good deal. If you have the money, buy a Netgear WNDR3800 and install CeroWRT, you'll probably see even better results.

Why the TP-Link TL-WDR4300

In short, its fully supported in OpenWRT Attitude Adjustment and works well for my needs:
