Router:
Asus RT-AC68U Revision C1
Firmware:
Asuswrt-Merlin 384.6
Bridge:
Linksys E4200
ISP:
WISP with
50 Mbps Down
15 Mbps Up
Modem:
Ubiquiti POE
POE-24-12W-G-WH

Setup:
POE (Modem) -> Asus AC68U (Router) -> Linksys E4200 (Bridge)
Issue:
I will be on a 5 GHz Channel that only I use, and another user will be on the 2.4 GHz Channel. If any other user starts to use bandwidth, the ping will spike to over 1000ms and can stay there for several seconds. These ping spikes are caused by any activity, and doesn't come close to saturating the 50 Mbps down. Even as little as half a Mbps of activity on the network causes spikes.
The spikes seem to be specifically from changes in traffic on the network. Some examples:
1. No traffic on the network, start a ping test and ping is stable, someone loads a Facebook feed (which consumes 1 to 2 Mbps) and ping spikes 500ms to 1000ms.
2. Start playing a 1080p Youtube Video on a desktop connected to the 2.4 GHz channel. Bandwidth shoots up to 10 Mbps down. Start playing another 1080p video at same time on another computer, bandwidth shoots up to 20 Mbps. Run a ping test as videos are playing and ping is stable. (Really weird thing, start another video while running ping test and network is already using 20 Mbps, bandwidth use will go up, but ping will usually not spike or only a short spike of 50 to 100ms.)
3. Start a ping test, begin a photo upload, upload uses 2 to 5 Mbps, ping skyrockets to over 1000ms and stays there for duration of upload.
I have tested the router with multiple QoS settings, as well as just shutting QoS off. No matter what QoS settings I set, I get the exact same behavior every time. I've also tried DD-WRT firmware, but it performs even worse than Merlin.
This appears to be an issue with how the router handles traffic, as the spikes are all cause by changes in traffic on the network and not by saturation of available bandwidth. Anyone know any possible fixes to this problem or is the Asus AC68U just a router with horrible buffer bloat?
