Aegis Posted November 9, 2005 Share Posted November 9, 2005 (edited) One of the things I could never figure out is why ISPs advertise 6MB download speeds, but on my computer I have never gone beyond 1MB. Anyone know why? I use Comcast BTW. Edited November 9, 2005 by Aegis Link to comment Share on other sites More sharing options...
compass Posted November 9, 2005 Share Posted November 9, 2005 first test your internet bandwidth ..this link wil help u to test the internet speedhttp://bandwidthplace.com/speedtest/ Link to comment Share on other sites More sharing options...
Zxian Posted November 9, 2005 Share Posted November 9, 2005 Not sure if this is actually a Windows XP question. Isn't Comcast a cable internet company? If so, then it means that you're sharing your internet connection with everyone else using Comcast. If the person nextdoor to you is downloading lots of crap, then your speeds are going to be affected. Link to comment Share on other sites More sharing options...
cluberti Posted November 9, 2005 Share Posted November 9, 2005 If you're paying for the 6MB service (and most times, you have to actually call and request the service - little trick they use to conserve bandwidth), and your head-end is the problem, the cable company will have to come out and either upgrade the equipment or create a new head-end.

dirtwarrior Posted November 9, 2005 Share Posted November 9, 2005 Is it possible to tweak the head end ourself? Link to comment Share on other sites More sharing options...
cluberti Posted November 9, 2005 Share Posted November 9, 2005 Unless you understand cable modem equipment and have the key to unlock the actual location of the docsis equipment, I'd say no . Link to comment Share on other sites More sharing options...
Aegis Posted November 10, 2005 Author Share Posted November 10, 2005 But isn't unlocking the docsis a violation of most ISP's contracts? Link to comment Share on other sites More sharing options...
cluberti Posted November 10, 2005 Share Posted November 10, 2005 yes, but those exploits have long been removed from the cable modem. And the equipment I speak of is not the equipment you get in your house, it's the huge "connection point" for all of the cable conections in an area - it's called a "head end", and it's a feeding point for all of the cable customers in an area. They all feed into the head end, and from there everything is routed to either another head end, or to the cable company's CO. Link to comment Share on other sites More sharing options...
suryad Posted November 10, 2005 Share Posted November 10, 2005 The 6 mbps stuff that is advertised is in bits most of the times. 1 byte = 8 bits. So to get the actual speed of the download, roughly try dividing 6 mbits by 8 which should result in 750 kb/sec if my math is not incorrect. I thinks thats how it is.

Bezalel Posted November 10, 2005 Share Posted November 10, 2005 Communication speeds are almost always measured in bits. Link to comment Share on other sites More sharing options...
Ðrзω™ Posted November 10, 2005 Share Posted November 10, 2005 yeah im on 10MBIT so my max download speed is 1.2MBYTES/sNot sure why the advertise it in bits... probs to make the non tech-savvy user think he/she is gettin great internet really cheap Link to comment Share on other sites More sharing options...
cluberti Posted November 10, 2005 Share Posted November 10, 2005 Yeah, I should probably have stated that. Be careful that you convert your advertised speed from bits to bytes - 6Mbit service should give less than 1MByte download speeds. Link to comment Share on other sites More sharing options...
Aegis Posted November 10, 2005 Author Share Posted November 10, 2005 The strange thing is that if my speeds are measured in bits, then I should have a cap of 750KBs, but my speeds have in the past jump beyond 1MB for a fraction of a second, then settle down. Can anyone explain this?And also anyone know what's the average bandwidth of a head end from Comcast? Link to comment Share on other sites More sharing options...
Bezalel Posted November 10, 2005 Share Posted November 10, 2005 The speeds you see during a file transfer are measured at a differant OSI layer. Often the bits come over the wire in a differant order than they were sent. When enough bits come over the driver puts the bits in order and sends them to the application, this is the speed you see during a file transfer.
