I have my home LAN pretty customized. Since I have to use the Fibe modem/router I decided it would be much easier to change the Fibe modem/router's configuration than the settings on all my network enabled devices. So, here's a few things I noticed...
The modem/router didn't have any password protection for the web administration interface. At least the default wireless passwords Bell uses are fairly secure. Still, it would be a good idea to set up some kind of administrative credentials.
Most changes to the wireless network properties are applied right away. So, making changes if you are connected wirelessly will take a while.
Most changes to the LAN settings (including LAN IP and DHCP parameters) are applied only after a reboot of the modem. That is a nice touch, as I did want to change the LAN subnet it was using and the DHCP settings.
I found the connection to be sluggish at times, with most of the delay seeming to happen while trying to look up host names. So, I disabled the DNS relay option and have the OpenDNS servers set to be assigned via DHCP. That seems to have helped.
UPnP is supported, so PS3 gamers won't have to worry about opening ports to be able to use the PSN or play online - If UPnP is enabled in the PS3's network settings. That should also make the router bit torrent client friendly.
My 360 didn't like the NAT it saw with respect to XBox Live. Not a big deal for me, as it didn't like my old router either so it was already using a static IP address. The Fibe modem/router has a very easy to use Port Forwarding section, so it didn't take long to get XBL working again.
