Packet loss - collision or signal strength

[Grim0x]

Title should explain my query.
I want to find an app for pf sense that will help me find out if my OUT packet losses are due to signal insufficiencies, OR, collisions between me and my neighbors.

I'd love it for PF sense, but Ubuntu or another Linux distro would be good too.

This inquisition stems from my other thread on internet dropouts.
I've found that it coincides with packet loss (OUT)

hm.
no edit feature?

Anywho - is there a way that I can make the packet sizes smaller in pf sense?

Thanks.
