Remedy for those afflicted with occasional keyboard lag and seized I/O?

I've been plagued with this for months but didn't want to say anything without finally investigating.
I troubleshooted thru the entire day yesterday. I have my seizes, freezes, and lagging when it comes to key I/O. Some days (yesterday) it is visited upon me frequently, many times an hour, for hours. Other times, much less. A couple minutes then goes away. Then comes back.

What they all have in common from one computer to the next is this: same wireless logitech keyboard and wireless logitech mouse. Battery power is fine. Thinking it was a crappy dongle, I changed ports and it cleared up for an hour or two. Then keyboard seizes came back.

Kept keyboard. Kept dongle. Put wireless mouse away. I had to dial my hardware back twenty years: I plugged in a wired mouse. I kept the wireless keyboard.
Been seize-free (no problems) for about 20 hours, thank politically-correct-deity-of-your-choice.
Remedy: wired mouse.

Hypothesis 1) motherboard/kernel communication with logitech dongle is problematic (but two computer in a row?)
Hypothesis 2) almost the same. Mobo/kernel understands the wired mouse plugged into its board and can talk/understand it, so no problems.

So: kernel has problem processing/integrating this logitech wireless device
OR: dongle old and corrupted? But this makes no sense as wireless keyboard is fine.

Please comment on my scientific method or lack of it, it's not my specialty. Thanks again.

Also, @elfprince has an alternate remedy for this here: https://discuss.getsol.us/d/3667-budgie-freezes-mouse-trackpoint-trackpad-nothing-is-clickable/15 if my info is not relevant to you.

***update. over 24 hours have passed with the wired mouse as the fix. I have had sieze-free keying all day for the first time in a long time.
***this is either a placebo that I'm swallowing to make me see rainbows and unicorns, or this fix was significant in the 'good guess' department.

Brucehankins thanks for your response, that's a lot of anecdotal evidence that supports the device theory. "they do have an app for the receivers that allows you to pair as well as update firmware."---now that might be helpful.

elfprince we all have little hangups, and seeing more cables and wires on my desktop was my little ocd ..that's why I went wireless with mouse/keys. But it really makes no difference as I'm plugged back in again. I agree with you 500% on ethernet. When I click the 'connections' taskbar icon on wife's wifi W10 laptop, it shows piranhas and freaks everywhere. People name their wired connections so profanely...wireless seems like the unprotected wild west, circa 1850's...

Anyways: UPDATE #2: well into a second productive day after removing the wireless mouse and swapping a wired mouse. I haven't had a hassle-free Solus working environment for weeks. It's been 2 days of bliss.

Questions: what would cause wireless hardware to deteriorate it's relationship to an operating system?
Question: or is it a kernel thing?
Last question: is it even worth search-engine-ing "HARDWARE CONFLICTS LINUX KERNEL"? Do I have time for that?

Brucehankins even if the dongle, uh, I mean 'unifying receiver' went to heck then I can see where one is wonked.
If one is not wonked then:

Read the things the DEV Team did with this thing in changelog. It's a powerful tool. But 1) a can of worms I do not want to open up and 2) a can of worms I don't have the brain power to process. I'm happy now.

elfprince yup I did type those search terms in and saw a common theme in just the first page (wireless problems). But I didn't read nothing, No time! Thanks for your help, kind sir. I walked my hardware back a few years, but I'm pretty happy I did.

MODS: I'm pretty sure I've narrowed it down to 1-2 culprits. I have almost 48 hours of peace being hard-wired. SOLVED, please.

Axios never got to see it.
