Hi! I have peplink 1350 with firmware 5.1.3. I wish to upgrade to 5.3.12 but I want to know if I still need an unlock key to do this since my warranty has already expired.
Unlock key is only needed when doing a major upgrade that means upgrading from firmware 4.x ti firmware 5.x.
If we are already on firmware 5.1.3 then you should be able to upgrade to the latest firmware 5.x currently 5.4.6 without any problem. And here is the firmware 5 release note for your reference before upgrading.
Thanks for clearing that up, Kurt. I shall proceed with upgrading my peplink today.
