I'm using two TL-SG105E 2.0 switches and one TL-SG108E 2.0 switch.


They're all running 20160526 Rel.34615.


Periodically, two of these switches have reset themselves, losing their VLAN configuration and their own IPs. In one case the switch retained its user/pass, I don't remember the other case.


In the first case, the switch reset itself after I powered it off and on again. In the second case, it just randomly did this late at night while I was using it.


Either way, I was forced to hunt around subnets/vlans looking for the switch, until I found it squatting on IP 192.168.0.1.


Before you ask, I hit the "Save Config" button several times, and even rebooted these switches with the "Save Config" option checked in the past.
