I’m on a bad network (airport with log-in-wall) but can accept websites etc just fine. There’s mainly a sync problem with ownCloud. It seems that the client tries to sync 3 pictures at the same time. The bar goes up to smth like »15 MB synced«, so actually 2 of the 3 pictures should already be through. Then however it errors and none of the images are actually synced.

The activity log looks like this:

So what's the bug?

Could you activate Automatic Bandwidth Limiting and see if it improves the situation?

Looking at the errors it also looks like if the Airport WiFi really does mess a bit with the requests..

@ogoffart the bug is that effectively nothing syncs, even though there seems to be some partial transfer.

@guruz I could, but I left the airport already. It was Melbourne, for the record. Nothing from the logs which is useful? I mean, if the airport wifi messes with the requests we should fix this, since lots of airport wifis (and other wifis with log-in-walls) tend to do that, but people expect their stuff to sync just fine.

Similar wifi here in Dubai as well … I now activated Automatice Bandwidth Limiting, but still waiting for any activity in the sync log about images.

It only seems to happen with images or large files too … this is what I see:
capture du 2015-10-30 05-00-49
and then

capture du 2015-10-30 05-02-35

As you see, new files are just piling up below the progress bar.

Ok, seems to have worked now. After activating the Automatic Bandwidth Limiting at least the indicators on the images switched and they seemingly synced.
Can’t that automatically be handled? I’d assume that the default of no limit takes care of that?

See also the issue you closed for some seconds #3382 :-)

What are measurable things we have to detect your kind of situation?
I don't see that you got "real" timeouts in the log..
Which speed did you achieve? The 67 KB/sec on your screenshot are not too bad actually.

Unfortunately the default is no limiting (which is what you had I guess)
Switching to automatic limiting at the moment sets parallelism to 1 which is not good as a default.

Please reply on #3382 not here..

Well, good questions. ;) I can’t answer that, I suggest you go check out an airport and think of something because you know way more about this than me. :)
