Summary

The ZyXEL B10B (VMG3925-B10B) is an all-in-one ADSL/VDSL/FTTP router with dual band, 2.4G and 5G WiFi, 4 Gigabit network ports and a separate WAN Ethernet port. Suitable for Home or small office use. AAISP started supplying these in March 2018

Basic Specs

  • 4x 10/100M/1000M ports.
  • Modem supports VDSL (FTTC) and ADSL/ADSL2+.
  • WiFi is 2.4GHz and 5GHz, 802.11b/g/n, 802.11a/n/ac
  • Broadcom 63168 chipset
  • MTU 1500 when in bridge mode not possible yet, but we are working with ZyXEL on this. (2018-03)

Suitable for:

  • ADSL1, ADSL2+
  • VDSL (FTTC), G.Fast (Modem doesn't support G.Fast, so you'd need a separate G.Fast modem)
  • FTTP, FTTPoD

Router and Modem modes:

  • an all in one modem/router/wifi
  • an Ethernet (PPPoE) router plugged in to a separate VDSL or ADSL modem or a FTTP or FTTPoD ONT
  • a bridging modem to a third-party PPPoE router (e.g. FireBrick, Mikrotik etc)

'Consumer' grade

It's worth noting that this is a consumer grade router which ideal for home use or for small offices. Different or additional hardware may be more suitable for larger or more complex networks, larger offices or to cover a larger area with WiFi access.

Factory Default Admin Username/Password

Note: An AAISP configured router will have a different username and password.

Default/Factory Password
IP: 192.168.1.1
Username: admin
Password: 1234

Supervisor password:

The B10B has an autogenerated supervisor password (hashed from the serial number). Earlier models left a md5crypt type hash in /etc/passwd, however firmware AAVF.10 changed to a SHA-512 type hash stored in /etc/shadow. Prior to firmware AAVF.10 you will be able to read /etc/passwd by logging into the router as the "admin" user via SSH or Telnet. With firmware AAVF.10 and later you would have to log in as the supervisor user - but you'd need to know the password.... You would need to crack the hash (e.g. with hashcat), the password will be 8 characters long using characters 0-9,a-f (lower case)
