It appears my problem was IPV6.
I have not changed any other configuration, simply unchecked IPV6 in NIC properties and re-enabled my NIC.
So far hours of connectivity and multiple connections without issue.
Hope this helps someone, I'll report back if the problem returns
Figured it out, 3.3 release notes listed this:
All extruders must be declared explicitly using M584. In previous firmware versions, one default extruder was assign to driver 3.
Once I input M584 E3 in my config.g, it now listed both heaters and my extruder... off to a test print
Thank you!
Homing is working in all axis' now, finalized probe section looks like this:
; Z-Probe
M574 Z1 S2 ; Set endstops controlled by probe
M558 P9 C"^zprobe.in" H5 F300 T2000
M950 S0 C"exp.heater3"
M280 P0 S80 ; set 80deg servo position on GPIO port 0
G31 P25 X34 Y0 Z2.05 ; Set Z probe trigger value, offset and trigger height
M557 X15:205 Y15:205 S20 ; Define mesh grid
So now heaters, thermistors, and end stops working... moving on to other changes.
Thanks again!

M122 only listing one heater, but I see nothing wrong with my heater section in Config.g:
=== Heat ===
Bed heaters 0 -1 -1 -1, chamber heaters -1 -1 -1 -1, ordering errs 0
=== GCodes ===

Looks like i lost my extruder after the upgrades:

Worked now on:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.4.5 (2022-11-30)
Duet WiFi Server Version: 1.27
Thank you both !
Now to see if things still work... 
@jay_s_uk said in Upgrading after 1.5yrs:
3.3 zip file then try
Won't re-apply 3.3 now, same error, even though I'm already on 3.3:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.3 (2021-06-15)
Duet WiFi Server Version: 1.25
I'm using the Duet2CombinedFirmware.bin file
Well I got to 3.3, but 3.44 or 3.45 just causes an error when trying to update:
Error M997: In-application programming binary "0:/firmware/Duet2_SDiap32_WiFiEth.bin" not found
@jay_s_uk - Thank you.
Can I go straight to 3.44, or do I need to take smaller upgrade steps to get to 3.44 ?
Hey guys,
Long story short, my printers sat in storage for 1.5 years, just go them back online and working.
I'm currently rocking the below versions:
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.2.2 (2021-02-11)
Duet WiFi Server Version: 1.25
I'd like to upgrade to the latest stable releases for all the nifty new bells and whistles, but the release notes are longer than a college essay - LOL
Anyone have any cliff notes as far as config changed needed to remain functional after the upgrade?
