I want to report an issue I had the other day doing a semi-automatic firmware dowload&update on an AC68U Aimesh Node in the Web interface.
Setup:
- Main router: AC86U on Merlin 386.11.
- Node to be updated: AC68U with approximately a year old official firmware.
What happened?:
Started the update. It took forever, so I closed the WebGUI tab and opened it in a new tab again
Now I could browse the Network Map page (but things were moving slow), but as soon as I clicked "Aimesh" on the left menu, I did not get the Aimesh map, but the same hanging progress bar of the update (I think it said something like "downloading firmware").
Eventually, the whole Web GUI slowed to a halt and crashed, requiring a manual restart of the AC86U main router.
After rebooting, the network worked as normal, but the AC86U had very high CPU loads. Restarting did not help.
Had to update to the last official firmware in order to get rid of the high CPU load.
I then updated the AC68U from uploading the firmware file via the web interface, not the Update button, which worked.
I have not tried to flash the AC86U main router back to Merlin yet, as the network is under daily load by multiple users in different households whose patience I don't want to strain, so I have to wait for an appropriate timeslot.
Other details
I have upgraded to the same firmware before on another AC68U node in the same network, which caused an issue requiring a manual restart on the AC68U node, but it didn't crash the main router.
Conclusion:
Updating the AC68U via the Update in Web GUI is buggy and unreliable.
