Well, normally it shouldn't continue to go lower; it would automatically find the right link limit and stay there. For example, on my connection my ISP bandwidth goes between 10,000 and 12,500kbps, so for bandwidth I just set it around 15,000kbps and it automatically sets the link limit throughout the day during periods of link saturation. It's always around 10 to 12k.pkm wrote:Ok so what if you have people watching videos, link gets congested. Now the ACC is lowering the link limit slowly because of interaction with pings. And that link just keeps going down and down, fully bottlenecking and choking everyone still trying to use the Internet.
Now with such very very little bandwidth and wiggle room pings would soar 10x than what they were while the link limit stays down and no one can load their videos anymore. Only fix is to reset ACC to get back to max link limit.
This is just ongoing basis for me, I fix one problem another one comes right behind it.
But for that to work, pings need to stay normal/low when there's no load on the connection. If that doesn't happen, then ACC won't work as designed. Since you mentioned that your 8.8.8.8 pings were high (over 100; did you try another server?), I recommend shutting off ACC and just keep a manual bandwidth limit. It's not a big loss; remember that QoS in all other routers apart from Gargoyle work that way.
You can play around. If your ISP download limit is 10,000kbps, maybe try 9,500 or 9,000. Then fully saturate the connection (download a big file or torrent) and run a speed test on a phone/tablet. Did the ping remain low? If yes, that's a good limit... or you can even try raising it a bit. Did the ping go higher? (in the 100s-1000s) Then you need to lower the bandwidth limit... maybe remove another 500kbps. And so on
Hopefully your Internet speed stays stable throughout the day. If you notice that at times your pings go high on speed tests during link saturation, you should consider lowering your link limit since it means your ISP is experiencing saturation.
