TP-Link had released new firmware for this nice cheap 10-Port GigE managed switch back in January. I just found it and after doing a config backup, updated.
The new firmware seems to have some NTP improvements, still checking out what else has changed.
All the config was _LOST_ during the update, putting the switch back to a initial configuration. You’ll find the management IP switches back to 192.168.0.1.
Well, do I care? no. It’s so quick to configure that I didn’t even bother to reload the config backup 🙂
If you have a separate management VLAN and reach it only via a trunk port your mileage may vary.
