Category:ZyXEL VMG3925 B10C
The ZyXEL VMG3925-B10C (B10C for short) is the elder sibling of the VMG1312 and was introduced March 2019 as a replacement to the discontinued VMG3925-B10B - it benefits from having Gigabit Ethernet ports and dual-band WiFi, you can see more differences on the VMG1312 Vs VMG3925 page. The specification is very similar to the VMG3925-B10B that it replaces (in fact the same firmware is used on the B10B and B10C), but benefits from a re-designed web interface (which is also available on the B10B from firmware version AAVF.12).
