Most costumers I install internet for get 5mb with the 6mb package and 12 with the 16mb, also depends on the computer rig you are using. An old azz dinosaur wont be able to handle even 2.5mb connection speeds so the speed tests wont be accurate!
Biggest thing with broadband internet from cable companies are the lines running to them. Old rg-59(smaller old school line) wont carry enough signal over a long distance, pus they get corroded after a few years. New rg-6 lines can carry excellent signal are made better to last longer and if the fitting are properally installed you wont have any problems. Another thing to note are splitters that can go bad, the drop (incoming line from the pole or underground line from the cable box outside to your house) going bad over the years or getting water in it.
Iv installed comcast cable in million dollar homes with the sickest computers around and I was shocked at how fast their internet speed was with just the 6mb connection.
It all comes down to workmanship.
Fios rewires your whole house when they install they setup, almost every cable line is rewired along with the telephone system. No wonder their are no problems, but thats the first install of their service in your home guys, cable has been reconnecting service to homes with people moving in and out and theyre not going to pay a ridiculous amount of money to the cable company to rewire everything if they dont have to thus leaving old lines in homes causing bad problems.[end/rant}
