D6400-V1.0.0.56_1.0.56 Firmware Upgrade issue

[MRBrobst]

I have a company laptop computer that I use when I am home.  It has worked fine since before I updated my firmware on my D6400 Modem/Route in January.   Since that firmware update, my company laptop has not been able to stay logged into my company's VPN service for than about 10 minutes.   I checked the Router logs and here is sample of what keeps happening..

I have to keep logging off/on my companies VPN service which is very annoying.    Before the firmware update everything worked fine.  I verified the IP address and it is a legitimate logon server for my company.

If you had no other issues with the older firmware that your VPN worked with I'd suggest you install that level firmware and call it good. Netgear's firmware seems to be their Achelies heel. They do good hardware and seem to skimp on their software. Other than these forums support is almost non-existent.
