Can't access modem settings page (CBN ch6541e)

I'm using CBN ch6541e modem and I can't access the settings page.
The internet was slow so I decided to try to reset the settings to factory values (I was holding reset button for 10 seconds until LEDs started to blink) and then I tried to setup my wifi but I couldn't access the settings page.
Before the reset I could access the settings page, it's on this IP: 192.168.0.1

If I try to open it in Firefox I get: `The connection was reset`

I even tried with `curl` and this is what I got:

curl: (52) Empty reply from server

Response from `route -n`:
