I currently have a DSL download up to 1 Mbps / upload up to 384 Kbps with verizon. I would like to get wireless internet in my home for which I only need the gateway thing (modem + wireless router, I think). So I called to order it and I was told that my internet speed would be too slow to support wireless (little to no connectivity on my laptop). I can't afford FiOS. What is the minimum speed I need for wireless?
