I made the switch last night from RoadRunner to Earthlink. All it took was a phone call. The Time Warner tech did everything while I waited. My cable modem rebooted and in two minutes I was an Earthlink customer. Didn’t even have to get a new DHCP address.
Now I’ll enjoy $30/month for six months of Internet service and then $41 afterwards. Plus, Earthlink is public hotspot-friendly.
