USG100 self signed certificate in certificate chain
I have two USG100 (home & office). Neither has been rebooted or had config edits for many months. This morning, both of them are showing certif errors: this looks like ZyXel's fault if it happened on two independent boxes. Is there anything I can do?

Possibly you are correct, but here is an extract from 3.00(AQQ.2) support notes: Please first jump to 2.20Patch2 C0, 2.20Patch3 C0 or 2.20Patch4 C0 before upgrade firmware from above 2.20Patch2 C0 to 2.20Patch5 C0 and later.
Zyxel support were doubtful that I could retain configuration on the older of my two USG and wanted me to do a factory-default reset before stepping through the updates. I tried without reset anyway: it worked.
Now I will never know if reset & go straight to 3.00 & reconfigure would have been faster or easier.
