Is my connection unreasonable slow?

I'm running a 1.5mbps dsl connection through at&t. I understand 1.5 is a low and relatively slow connection, but is it slow enough that it should fail to buffer any kind of web page at least 10% of the time? It also won't buffer any youtube video above 240p without like an hours loading and won't hold a stable Wi-Fi connection with a PS3 or iphone. Understanding its a slower connection, is it supposed to be that slow?

Added (1). In response to Jason. 1.5 mb/s converts into 192KB/s. So I was curious how dividing it by 8 gives you the speed in kilobytes?

Yeah that is normal, as the connection speed they give you is in bits. To get the actual speed you are getting in bytes, you divide the number by 8.

So you are getting around 18-20KB/s, which is just barely faster than dial up. So that is why you are having trouble.

  • Why is my iphone 4 connection going so slow? Everything else like all my computers are working fine but my iphone is so slow in connecting to youtube
  • Slow wireless connection to my iPhone? It's 0752 so it can't be all the beighbours downloading and my computers turned off, the router is just sat there as normal, nothing has been changed but the wireless connection on my iPhone is really slow. I'm using it in the same room as the router. Any ideas what it could be? Happens all the time, in and hour or two I'll try it and it will be fine.
  • Network Connection for Itunes match? Alright so i'm thinking of getting Itunes match right now as I have thousands of songs and I'd prefer to actually not download them to my Iphone, just listen to them through Itunes match thingy now my question is; do I need network connection to listen to the songs who are on Cloud?
  • My iPhone 5c connection is so slow So I recently got the iPhone 5c from T-mobile and it was great the first two days, the internet connection was super fast and everything. Then it went all super slow, I can't even watch YouTube videos cause its that slow or load some pages! Also, on the top left corner where it's says its signal strength reads: LTE or sometimes 4g. I thought these meant it was supposed to be better?
