Sergejs Kotovs Posted April 20 Posted April 20 Hi, I’m experiencing a strange issue with my NetDuma R3 and wanted to check if others have the same problem. When I run a normal speed test (e.g. Ookla Speedtest), I get my full speed: Download: ~220 Mbps Upload: ~40 Mbps However, when I run the Waveform Bufferbloat Test: Upload looks normal BUT download drops massively to around 10 Mbps This is a huge difference (more than 20x lower than expected).
Administrators Netduma Fraser Posted April 20 Administrators Posted April 20 If speedtest.net is showing your normal speeds then the router isn't limiting you but try toggling speed test bypass in Ping Optimizer > Advanced. Otherwise it's unlikely there is any feature impacting it and is more likely the site.
Sergejs Kotovs Posted April 21 Author Posted April 21 Yeah, Fraser, you were probably right. I checked this morning and everything’s fine. Yesterday it was messed up, now it’s normal. That site is just buggy as hell — screw that site.
Sergejs Kotovs Posted April 21 Author Posted April 21 Here are my results today — 10:47 AM, April 21, 2026. And the next day it looks like this… everything is kinda weird.
Administrators Netduma Fraser Posted April 21 Administrators Posted April 21 Very bizarre! Perhaps their servers were under heavy load at the time. Thanks for the update!
