My new comcast service was installed 6/09/14 with the Blast package (105/10 speeds). The first 24 hours it wouldn't return better than 24 Mbps. I called customer service and they discovered they had the wrong code for my service. They put in the correct code and about 15 minutes later I noticed speeds nearing 70 on my laptop (hardwired). On 6/12, speeds were down to between 50-60. When I disconnected my laptop and hardwired my PS3, its internal speed test is returning speeds of 21-27Mbps. The technician said my modem/router is an all-in-one unit, so I don't believe I can bypass the router.
My questions are:
1.) When will I experience the advertised speeds that I was guaranteed? I say "guaranteed" because the sales rep I spoke to did verbally guarantee that I would be receiving the advertised speed, despite my doubts.
2.) Why would my laptop and my playstation return such drastic differences in results?
Any help is greatly appreciated.
