LAN - no UNC paths - no SSH etc - may be router

At this point, what I'm looking for (unless you have a better suggestion, i hope):
What if any "one size fits all" one-click fix type of utility might you recommend for Win 11. I try not to mess with those things anymore. Back in the XP days i suppose i used them often. I know there's a win-tweak or something that like totally reconfigures the registry. a little app that kind of pops up in the middle of the screen. gives options to update the reg, etc. you prob know what i mean. i can't rem the name. and maybe i don't need to go that far.

The Problem:
My ISP is Comcast / Xfinity. My connection goes out regularly. No idea why. Anyway: let's just say, I have to restart my router (Wi-Fi / Ethernet) on occasion. Most frustratingly, this often results in somehow messing up the connectivity between systems on my LAN. I don't know if it's my impatience, expecting this to be back "on-line", and when it's not I start running commands and trying to figure it out. (if 30 mins classifies as impatient).

On SSH attempt, i get the following (i've researched it, so i get the gist):
ssh: connect to host linux21box port 22: No route to host
NativeCommandExitException: Program "ssh.exe" ended with non-zero exit code: 255.

come to think of it. i did run the following, which is most likely what did it.
netsh winsock reset
netsh int ip reset
netsh advfirewall reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew
but have since executed the "Reset Network Configuration" option in Settings > ntwrk.

Coincidentally, I had opened up port :80 on my Win system the night before, but that didn't work. i played with it a little bit, but it's not the env that i know how to tweak. I don't know why I can't get that (e.g. view HTTP served files from Windows from another on the LAN). i have the "Samba" server setup as well. typically, i can view and edit files on the linux box with no issues whatsoever (the reverse, not so much).

So the only things I recall consciously changing are that Firewall incoming port exception (which i disabled after it wasn't working).

Well? There was an update the other day. Yesterday maybe.
`2023-09 Cumulative Update for Windows 11 Version 22H2 for x64-based Systems (KB5030219)`
`2023-09 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 22H2 for x64 (KB5031217)`

verified install date: 2023-09-13
a few things might have been acting strange, but i was focused on something and didn't really have time to ... be concerned. I run the Windows Subsystem for Linux (WLS) as well-- which by the way is the most awesome thing ever for someone like myself! Sadly, Windows updates often have some negative effect on it, usually related to UNC paths. I've seen .NET updates cause malfunctions there as well. not sure why. far too much to try to cram into my aging brain! haha.

Clearly my WAN connectivity hasn't been affected.

Of course the LAN seems to "sometimes work" and sometimes not, only seeming to work for a minute or two after restarting the router. that processes takes a few minutes, so I've only experimented w/ it a couple of times.
E.g. how weird is it that the Mapped Drives are "Green" at first (meaning, first open of Win Explorer after a restart for example). then that goes away to the red X's.

Thank you for reading! Have a great day!
