After updating to latest FW 21 & resetting, now can't login to router. I've tried admin/1234, zyuser/1234 and supervisor/zyad1234 and each time invalid username/password error in GUI. Router is few years old bought off ebay, not sure if locked or not but updating went well and problem happened after using the reset option in GUI. On previous FW, zyuser and supervisor would allow access but not admin/1234.
Already went through reset pinhole and few reboots. Any help would be appreciated.
Thanks.
