Whenever a cloud sync type application runs in our house, it completely kills internet access for everyone - presumably because we have low upload speeds of about 800kbps. So I'm thinking I might need to configure QoS.
Is this correct? Is there any other solution I should be looking at? When I use Adobe Creative Cloud syncing it seems to go to a particular IP - so I can set priority to low based on that IP, I think. Is this the wrong way to go about it? Of course I'm relying on that particular IP always being used which isn't a given, but it's all I've got to go on so far.
does the app not allow you to throttle upload speeds? I know dropbox etc do.
But this is made by Adobe.
Yeah but I don't just want it throttled, I want to apply priority. So use all the available bandwidth unless something else wants it. In other words, I want to give lowest priority to the cloud sync traffic.
I think I've set up QoS to do this but it does not appear to be working.
Which router is it?
Generally on home gear, (and TBH a fair amount of enterprise gear also) it doesn't work quite as well as you'd hope.

Doesn't seem to be working for me at all. Tried using an IP range, but not sure what the syntax is for that - it has four boxes separated by a . and another separated by a ~. What the heck does ~ mean in networking notation? I'd have expected a / or a -
So put in a single IP that I know it's using, and set that to lowest, with a minimum of 0% bandwidth but selected the tick box to 'allow more'. Everything else set to highest. To me, this means that the upload can go down to zero when other stuff is using the network, which is what I want.
But when I did this, the upload traffic for Adobe went to zero all the time.
Can I buy myself a router that'll actually do this?
I already googled it, thanks though.
Looks like the original issue with nothing being uploaded was because the app had dropped connection. Restarted it and it continued to hog the bandwidth.
So in my QoS settings I have set upload to a minimum of 0% for this IP but I clicked the box 'allow more'. To me this suggests it can go over 0% but it's not clear under what circumstances. Seems like the router freely allows more without any kind of prioritisation - so it continued to hog the bandwidth all the time.
I've set it to 40% now but un-ticked the 'allow more', and it seems to work. But I don't actually want it to limit it to 40% all the time.. just want it given lower priority.

Come on, that's not totally fair mate, I mean QOS successfully stopped our VOIP soft phone solution at work from dropping calls. Now when the network is busy, calls merely turn into unintelligible noise.
Do you not want to give it 100% but give it lower priority than other applicatons/addresses ?
Not that I've particularly studied it but I thought that was the principle of QoS.
I think that, on this router at least, the 'priorities' aren't actually ordered priorities, just diffserv categories. So 'low' priority is just a name for whatever you conifigure. So setting 'allow more' just means that the data hungry app, Lightroom in this case, will continue to grab all it can.
So if I give it 100% it'll just take it and won't defer to other traffic.
You basically want it to be scavenger class traffic, but to be done properly that needs packet tagging or some sort of protocol mapping table and proper routers capable of shaping accordingly. As I think you have realised, I think all you can do is diffserv with different reserved bandwidth settings.

Maybe you've run out of reserved EF bandwidth on the links.
IANA network engineer, though.
I think you've got it backwards.
When you're setting a "percentage or more" you're reserving bandwidth, not restricting it. So rather than applying a setting to the problematic machine, you want to be applying settings to everything that isn't that machine.
But there's an 'allow more' button. Surely without that selected, the percwnis also maximum too?
I think you're right thoigt, the emphasis is on guaranteeing not restricting. There is however an option to tag packets, need to investigate that more.
