Keep SSH enabled at EVERY boot

All I ever did was enable SSH in raspi-config and then it was enabled for as long as I didn't change this setting. Why did you create the blank file? Maybe that's where things went wrong for you?

Yes, I tried just changing the setting in raspi-config at first. That didn't seem to make the SSH server "stick" at each boot and reboot. That's when i went for the creating the ssh file approach

It's one of the official ways to enable ssh in Retropie (and Raspbian), so it shouldn't cause this behaviour.

the deletion of the file is correct. it uses it to set SSH on and that setting should maintain between boots whether the file is there or not. something else going on here...

i think you must be right! i have the pi setup as 10.0.0.3 on dhcp reservations, and the Pi tells me it's IP is that one...i just tried to ping the address via windows10 machine, but get "destination host unreachable"

this, even thought the Pi is definitely connected to the network and it can, for example, download updates and ES themes

hmmmmmmmmmmmmmmmmm

update...unticked a "WMM" wifi multimedia setting and rebooted...now i am connected, can ping, can SSH

I do experience a 25% packet loss when pinging from my windows machine. idk if its odd or normal, but its always the 3rd ping that is dropped

Firstof all, it seems more like a network issue than SSH disabled. You may verify SSH daemon status by systemctl status ssh.service, ps -ef | grep sshd or whatever method you prefer.
Second, a A class private network is quite overkill :)
Packet drops on a wired local network without routing should be extremely rare (at most).
Some points you may check :

duplicate IP (would be a shame to choose same through 16 777 216 possibilities ;)
more than one IP in the same subnet on the RPi (could your Wifi and your wired network be both configured ?)

Anyway, an ifconfig -aon the RPi and ipconfig /afrom your workstation could also help could help.

ifconfig -a on the RPi gave me ...

i think you may be right about it being an issue with my network as opposed to it being a problem with the RPi...for example, I'm SSHing into right now. But i'm still experiencing some network connection issues with the RPi that i do not experience with other machines on my network...including SSH connectivity but also accessing samba shares

@creativename
Let's start by unplugging the ethernet cable fro the pi if you don't use it.
Everything seems ok besides this.

Don't rely on ssh or cifs to check network. Nothing says "it's good" as a ping without packet loss :)

Regarding your samba issue, IIRC it's a recent windows restriction that doesn't allow anonymous SMB access. So not the same issue (and not retropie fault IMHO).

@sano no ethernet plugged in

FYI for future seekers...

I disabled "WMM" wifi media mode and rebooted. i am getting better overall connectivity with all my devices (previously i could connect to them but didn't always see the IP listed in router configs "attached devices" even though they had IPs), and this also seems to have stopped me from the frequent issue of not getting SSH access

why did it work? not sure. but it works! maybe it was something else, but i would suggest giving it a try to people with similar probs. i don't know that WMM does much, since i haven't noticed any problems with other services since turning it off, such as netflix or streaming from my plex server

might not be related but when i shutdown and physically take the power off overnight. My wifi stops working i have to remove the usb dongal and put it in again for the system to work again. It doesnt do this everytime just most times it does. The thing is i have to shut my pie down because its in a bartop and there is no support to turn the monitor off just a screensaver that leaves the backlight on
