Mouse moves jerky / erratic during downloads

Reported by: Ken Kuhns Owned by:
Priority: normal Component: FileZilla Client
Keywords: Cc:
Component version: 3.58.0 Operating system type: Windows
Operating system version: Windows 10 Version 21H2 (OS build 19044.1556)


Using Windows 10 Version 21H2 (OS build 19044.1556)

Filezilla version 3.58.0

When downloading files, the mouse becomes jerky and stutters as I try to move it. When the download completes, it goes back to normal.

The computer in question is a laptop, so I'm using an external wireless mouse (logitech m325) - and while this problem is happening, mouse functions are smooth using the laptop's track pad. I am using microsoft provided mouse drivers.

Physical limitation, only cables can eliminate the problem.

Wireless data transmission over WiFi and wireless mice share the same 2.4GHz frequency band. One device can easily drown out another in the vicinity, especially with old or low quality devices lacking the sophisticated algorithms employed by modern devices to share the spectrum more fairly.

I should mention that while the computer in question is a laptop, it is on a wired ethernet connection.

After looking further in to this issue, I discovered it is an issue with Logitech's Unifying Receivers on their wireless mice. I'm using a Logitech M325 mouse in this instance and apparently the small dongles are very prone to interference from other devices. The recommendation is to move the dongle to another USB port or hook it to a USB extension cable. I had the dongle plugged in to a docking station - I moved it to a USB port built in to a secondary monitor and the problem seems to have cleared up. This is not a Wifi interference issue nor a Filezilla issue, rather an issue with interference from USB ports and other electronics.

I had noticed I was also getting this same jerky mouse issue when transferring larger files using other methods (copying to a server share, etc). I started looking in to it and found my answer here:

So Thanks - and hopefully my info above can serve as an FYI to others!
