Upgrade is required because of security issues or because something doesn't work as expected due firmware bug.
If everything works for you and security is ensured by something else (no rogue users can attach PAP2T in local network) you need no upgrade.
Not 100% sure if security is protected, and I do have issues with remote connections. So I would rather upgrade and be on the last firmware. Does anyone know where the download is located and which one I need for PAP2T?
PAP2T is in End-Of-Support state for long time. Security bugs, even known, are not fixed - latest firmware can't be considered secure. You will need to ensure security in another way even after the update.
Firmware is copyrighted computer program. No one but Cisco can distribute of it. May be, Google may help you to discover an unauthorized source of such firmware.
I could not upgrade to 5.1.6 from software that I found through google on one of cisco / linksys sites.
i tried to upgrade using the Windows utility - whereby an application launches, obtains the details of the PAP2T, uploads the firmware and then it appears it is waiting for the device to upgrade and then says "failed - upgraded to 3.x.x - the firmware which was already on PAP2T.
the link that you included did not have the firmware.
can you help?
My bet is that the computer is blocking the upgrade. Chances are it is the Windows firewall, antivirus, or some other utility to keep you safe. You need to answer "Allow" if Windows offers to block for you.
Try another computer, or disable the inhibitors on your computer and reboot.
You can also install a TFTP server on your computer, there are several free TFTP servers for Windows on the Internet, example SolarWinds.
