It would be beneficial if those you have tried this firmware version to provide the following information:
1. Did you upgrade the firmware from the webgui? - YES
2. If not, how did you install the firmware?
3. Did you do a complete factory reset before installing the firmware? - YES and i tried the other way round with a factory reset afterwards.
4. Did you import a saved configuration file or did you manually configure router settings after a factory reset? - Manual configuration.
5. What type of internet connection do you have (Fiber, Cable, DSL, etc)? - FTTC (UK)
6. How is your router setup (Router, Access Point, Bridge, etc)? - Router (I also have Lyra Mini as a Mesh node but this works fine even when having issues with the router)
7. Are you still having problems with a minimal setup, having completed a factory reset and manually setting up the router (No VPN's, no IA Protection, no port forwarding, etc? - Yes, still having issues with no AI, VPNs or Port forwarding configured.
8. If you had no issues with a minimal install/config at what point did you start experiencing issues? - I ad issues even with a minimal configuration.
9: Attach your log file if you can. This applies to those who have no issues and those who do have issues. - May add this later.
I have this router and I'm currently using firmware version
3.0.0.4.384_6436. Stability issues are good. I'm reluctant to install the newer firmware until I figure out if it's worthwhile. Typically I wait to update my firmware to a known stable version or one that has patched exploits. Those who provide minimal information about their setup and issues really don't add much weight to the validity of their concerns. Many problems can be narrowed down to simply not completing a legitimate factory router reset. I know this is not the case in a many situations so I propose proving at a minimum the above information.
I'm actually looking forward to installing a newer version of the AX86U firmware that is stable, although I would appreciate those who have don't have problems and those who do have problems answer the above questions. Also. stability can still be achieved by some while others have stability issues. Typically comes down how things are configured in the router, what services are running, etc.
