Ker on "Slow backup and frozen Internet connection"

Same problem as @Maddog949 and @stumpjumper, but on a Synology DiskStation, with the IDrive Synology application. When a backup starts, the internet connection turns unusable. The backup itself is slow (after some days, 24GB of and initial 64GB set), but I could stand it, if the bandwidth problem can be solved. Otherwise, I have to look for another provider. I have other 500GB waiting.

How do I send the error report that you always ask for from the synology app? I do not find a "Send error report" entry.

Thanks for your atention.
(PS: I just realised this thread is 1 year old. I hope the technical team and the development team had already time to "look into this)
