It's so annoying having to constantly use sudo modprobe -r psmouse because the system decided to randomly drop the connection every X minutes/hours/insert random time period. Is anyone working to fix this?

Mouse is a Logitech M185

With the USB receiver it should appear as any other wired USB mouse. I have the M325 and do not have disconnect problems. It may be something is wrong with the mouse itself.

Have you changed battery lately?

If not using the receiver then might be some bluetooth problem.

I'm using the plugin USB receiver. I'll try a fresh battery

Never had any problems with my wireless keyboard/mouse combo, or my other wireless mouse either.

I doubt very much that Linux can differentiate between a USB wired and wireless (Plug in receiver) mouse. All it sees is the data from the USB port, not how it got there.

Play Bonny!

In the past I have had a similar problem with wireless devices. It turned out the problem was that I had equipment sitting between the USB port receiver and the wireless devices. The equipment would intermittently block the radio signal.

Yes, most likely. A piece of metal between them (for example), or they are just too far apart (the device from the receiver).

Also, keep in mind that the 2.4GHz band is filled with all kinds of noise emanating from all kinds of things other than computers, and even other computer-related noise like Bluetooth. Those other machines can easily be making enough interference to keep your mouse from working as intended.

For example, around here on a "noisy" day Bluetooth reaches noticeably less than 1.5 meters reliably. In contrast, on a good day I can get close to 10 meters of range on the same equipment.

As a personal experiment, I can't listen to music in the kitchen (with bluetooth headphones) when the microwave is on.

For reference my mouse is right next to the laptop.

2.4GHz is funny stuff. Reception of high frequency signals generally is like a black art. For instance 2.4 GHz generally goes through walls, doors & glass, but 5Ghz does not. That puts a complicated situation very simply, but you get my drift.

I have a pretty unusable 2.4G wifi in my RazPi because the aerial sees the metal box behind it as a Faraday shield. My keyboard/mouse are 1 metre from my pc and work flawlessly, until I plug a metal usb key into the usb socket behind the wifi receiver and I lose reception, despite having a direct line of sight to the receiver about a metre away.

Move physical positions to get metal away from both receiver & transmitters. I had to move my pc back for clear reception. Moving things works. Logitech are a good brand. People will raise a middle finger at any reception bug filed.

If you are using your wireless mouse with the Logitech usb receiver, you can plug the receiver into a usb hub then set the hub and receiver some distance away from your laptop.

I do that, and it works better.
