    Lightroom CC sync destroys home internet connection

    davefeldman Level 1

      I've recently switched from Lightroom Classic to the new CC, and made the unpleasant discovery that when Lightroom on my Mac is syncing photos, it basically takes down my home internet connection. Not only can't I load websites (or anything else) anymore, but everyone else in my house is subjected to a loss of connectivity. Obviously this isn't tenable in the long term—I can't go asking everyone, "Hey, do you mind if I take away your internet for an hour while I import some photos?" al the time.

       

      I've seen some related threads whose answers seem to range from, "Yeah, that sounds like a thing that might happen," to, "Change your router or cable modem settings." But no clear action I can take. What's my best path forward? This seems like it should have a simple solution: Somehow every other bandwidth-hogging activity I engage in manages to function without completely destroying connectivity.

       

      Thanks.

          I had exactly the same issue for a long time, which was only resolved when I changed my router. LRCC seems quite aggressive in its use of the available bandwidth, and my broadband connection kept being dropped by the router. It would automatically reconnect of course, but constant interruptions didn't go down too well in the household, especially with my online gaming son!

           

          Logically, there's no way that an app could cause that problem (I don't think), but it only happened when I was uploading via LRCC, and it only stopped when I changed my router. Conclusion was some defect or setting in the router wasn't playing well when operating at full upload capacity.

            Did you change the router, or the cable modem? I've got an Apple AirPort Extreme, which I would think is a pretty capable router. The cable modem is a Motorola SB6141, which I know less about.

             

            And I agree, it seems like an app shouldn't be able to do this, but the problem is very definitely Lightroom CC (and Classic didn't have this problem). With it running, the connection is practically nonexistent. The minute I quit LR, everything's fine. The only other app I've seen with this issue is Backblaze, but it has a throttle setting that you can use to solve it.

              Lr CC (or Lr Classic or Lr Web or Lr Mobile) do not cause my home network to slow down.

              Assuming we both have ver 1.1 of Lr CC, we both have the same software installed.

              If it works here, and on 100000s of other computers/networks but not on yours the cause of your problem is NOT the software.

              Do you REALLY expect Adobe to be able to produce a product that will work with every, conceivable, possible combination of hardware, other conflicting software, settings etc. on every computer on the planet.  REALLY?

                I was using a combined modem router, and I replaced it with a slightly older model.....and that one has worked fine ever since.

                 

                Not sure what else to tell you.....I wrestled with this issue for quite a while. It only happened when uploading (original files) to the cloud, and for a while I started uploading via the LR Web app instead. That seemed to be a little better, but would still get the occasional dropout, so in the end (as a test) I got the older router out of the loft, blew the dust off it and connected it up and I've not had a failure since. Like you I have an cloud backup system permanently active (Crashplan in my case), plus Dropbox, but only LRCC would bring the network down.

                  I had the same setup a while ago. With a typical asymmetric cable internet provider (120 down and 6 Mbps up) and an Extreme with a SB6141. The SB6141 only has 8 download and 4 upload channels. It is very easy to overload it by saturating your upload bandwidth. Other models with only 2 or 4 download channels do this even quicker. I had these sort of problems during uploads all the time (long before CC) until I switched to a SB6183 which is 16 download and 4 up. Completely solved that issue. Alternatively the solution is to use a router with QoS. The Airport is a very good router but it doesn't do QoS. QoS keeps any one device from overloading the connection.

                    I wonder if some of these apps (CrashPlan, Dropbox) do their own throttling to avoid this situation. (I did have a similar problem with Backblaze but was able to avoid it by turning on their manual throttling feature). And it's possible this is happening with other apps, too, and I just haven't noticed it because it's so rare I'm doing a lengthy, sustained upload.

                      Thanks Jao. I'd love to understand how the channels work in more detail—in particular, why does overloading the upload channels (i.e., syncing LR after an import) have such a dramatic effect on the download speeds if there are separate channels for each?

                       

                      Beyond that, I'm also curious whether it makes more sense to get a new modem with more channels, or a new router with QoS. I lean toward the former because it's cheaper and actually seems to be solving the problem (rather than avoiding it via QoS) but wonder what others think.

                        Adobe really needs to add this. It's the nature of many async broadband connections that download speed suffers if upload is saturated. Every other cloud backup/storage solution I've used has the ability to throttle upload.

                          Same problem. here. If Lightroom CC is syncing, then that takes up all of my bandwidth. I can't use the internet at all until it is done. Thankfully I can pause it and then start it at bed time. Even so, they really need a feature where I can manually limit the upload speed of Lightroom so that it doesn't take over everything.
