I only have 3mp running on DSL at my old place and never slow me down or anything. I had to change to u-verse for internet at the new house and still work fine. They upgrade it free to me from 3mp to 6mp when I add cable but I hate att cable so went back to comcast. Told them to give me back my 3mp. Now I only used my ipad and other device with wifi in the house while my desktop still waiting to get a new power supply or buy new desktop. Going to have to convinced my husband to allowed buying a new computer this week.
