Well, due to a lot of common questions, I must say that this firmware does NOT contain any web interface by default.
In order to install it you'll have to telnet to the router on 192.168.1.1, make sure you got internet connection (For ADSL / PPtP you can set the dialup manually) or if you got MPLS connection with the cable company, it will just pull DHCP.
In order to install luci web interface, after you got an internet connection, you should just run from the telnet session
# opkg update
# opkg install luci
# /etc/init.d/uhttpd enable
# /etc/init.d/uhttpd start
Another note is, that USB is currently not available due to lack of the usb modules for this kernel.
Hope it clarifies some things.
Again, feel free to ask if you got any questions.
