I have a WAN router at home which patches together the DSL and cable Internet subscriptions. I can assign different applications to different networks or simply use it in "rollover" mode where the second line is used automatically when the first line goes down. In the past I've used cable as the primary connection but it was down more than half of the time so I was constantly getting cut off from VPN access when the access line switched. Now I'm able to use DSL as the primary connection and use cable only if the DSL line drops.
I'm excited to have the new, faster connection. It seems to really make a difference.
