Can't access or ping my router, yet I can browse the internet

[PermaChanged]

Hey People,

I'm trying to install a draytek router but I can't access the web config on it. I can't ping the router either.

However, I can browse the internet through the router.

Is there anyway to know what the router IP is? I've tried 192.168.1.1 as per the manual but that won't load up.

Thanks
Jonny
