Quote from maczter:
I have had 3Mb DSL as a back-up for my RoadRunner (5Mb) for the past few years.
Obviously, the cable was faster (5Mb vs 3Mb), but I just upgraded my DSL service to 6Mb for $28/month from AT&T one week ago. My router (Xincom XC-DPG502
Twin WAN Router) normally does load balancing between both connections, but I took turns disabling each connection last night to test them out with the speed tests at dslreports.com and the DSL is marginally faster now as expected. I haven't had a chance to test the differences in latency between the two, but, based on past experience, DSL usually wins in that department as well.
