Can you access your CHR router with Winbox? With a console? What do they show?
For example, does it have an IP address? Does it have a route configured?
Does your PC 192.168.1.33/24 have a route to 192.168.122.0/24? Does 192.168.122.0/24 have a route to 192.168.1.0/24?
How remotely are you trying to access it? Other side of the country for example.
