UPnP not working properly in Firmware V1.0.2.116

[winwellsklo]

I have just updated the firmware to V1.0.2.116 on my R8500 router.

Once the update was done, I soon discovered that the UPnP does not function normally:

For example, my QNAP NAS cannot detect my router and change the port forwarding setting.

Although I double checked the settings of both router and NAS and had a cold-restart of them,

the port forwarding setting does not resume.

Is there anybody experiencing the same problem?

Yes, the problem is finally solved by resetting to factory default settings and rebooting for few times.

Thank you.

Did you reset the router to factory settings after the firmware flash?

New firmware sometimes introduces changes that are not compatible with the old configuration.

So while it isn't guaranteed to fix problems a factory reset is the first thing to try if you have issues with new firmware.
