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.

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.

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.

Shutting off acc makes things worse though. It might not seem like much because you have so much more speed compared to my 3Mbps. How much more bandwidth can I actually remove from my limited connection?

When the link becomes saturated, pings in game go much higher with acc off.

Also yes I have tried many ping targets. Google dns, open dns, ISP dns, other random servers and no help.

That's so weird! Are you sure the download bandwidth isn't set above what's actually available? It should be set slightly below. Go by speed tests and not by plan.

The only other thing I can suggest is to start REALLY low and test using the method I've mentioned above (saturate link with one device and speed test on another). You can start at like 1500kbps, then increase by 100 after each test (until you notice pings go higher; lower it by 100 or 200).

If you still get high pings even with such a low download bandwidth set in QoS, then your ISP is probably running some form of QoS, making yours incompatible.

Well i notice that the only way to stop the ACC from lowering link limit is to use default ping target (which is the modem) and since the modem is on LAN the filtered and normal ping never jumps around. Not sure if having LAN ping target benefits or not.

But as per the guide, its not always recommended to use default ping target. Maybe in my circumstance it is best to use default?

well you shouldnt use you lan gateway as ACC wont be able to correctly control your bandwith its better to use Wan Gateway and if you have a PPPOE use Bridge mode on the DSL Modem and input the PPPOE user and pass on gargoyle with this your port forwards will work and it will make QOS account for the overhead in DSL connection after that you can just use your adsl modem synced speeds for ACC and for upload you will have to tweak it yourself to the point where QOS seems to work on the upload side aswell as by doing this the default target for ACC wil automatically become the Wan Gateway which should be optimal enough in most cases for some cases i had this issue was that my gateway didnt increase ping one bit even under full load i had to use the second hop for qos to work but since then i get a diffrent wan gateaway ip which seems to be the best for qos atleast for me dont use your lan gateway e.g your modems ip use the wan gateway that should be optimal in most cases

I just wish that ACC was more dynamic in how it handles things. I think thats what screws me over. When the link speed gets lowered, it takes aaaaaages to get the link limit back up. Load up a download, but the link limit takes its sweet ass time going back up.
