Hi,
My first post on this site, but I have been following it for a while.
I have a second-hand boxed and very new-looking Zyxel VDSL router, P2812HNU-F1 which I can't access after a hard factory reset and even after trying the 30-30-30 reset shown elsewhere. Doesn't appear to have seen much use.
The only info I have on the Zyxel site is that user/password after a hard reset should be admin/1234.
All the LEDs function as normal, it responds to reset by LEDs changing to red, orange, than back to green. I can connect to computer via Wifi so don't think it is bricked. The DSL light is on when connected to phone line, but internet LED stays red.
It connects to
http://192.168.1.1 to show login page, but admin/1234 always show incorrect user name or password.
I contacted Zyxel customer service for help, and the router is only a year out of warranty, registered in 2013.
I don't think it is ISP firmware locked.
Does anyone have any ideas how to fix this?
The box wasn't ISP branded, and I don't think a UK provider used this model.
Thanks
