Why hasnt my DSL ever run as fast as it should?

Question

Ok so a few years ago we got verizon DSL, and we ended up getting the 768kbps or whatever it is around there. How come whenever im downloading from limewire or any website it only goes at about 180kbps?

weird thing though, i was on a wireless laptop that was connecting to this same internet, and when i downloaded from limewire (only songs though) it would finish before it got to its fastest speed, highest was about 480kbps. I know theres no way ill ever get close to even 700kbps, but why not 300 or something, i know im not alone but i just want an explanation. would a new modem help?

Answer 1

You must be getting 180KBps ...note the capital B ...from a 768kbps connection ...note the small b
There is a difference between the both
KB means kilo bytes
kb means kilo bits

If you don't understand computer networking then you will never understand the real reasons behind your so called "problem"

The reason you will never experience the full bandwidth and only get a reasonable amount of throughput is because...

* The traffic load may be lower than the maximum throughput.
* The channel capacity may be shared by other users. If a bottle neck communication link physical data rate R is shared by N users, every user typically achieves a throughput of approximately N/R if fair queuing best-effort communication is assumed.
* Flow control, for example in the TCP protocol, affects the throughput if the Bandwidth-delay product is larger than the TCP window, i.e. the buffer size. In that case the sending computer must wait for acknowledgement of the data packets before it can send more packets.
* Packet loss due to Network congestion. Packets may be dropped in switches and routers when the packet queues are full due to congestion.
* Packet loss due to bit errors.
* TCP congestion avoidance controls the data rate. So called "slow start" occurs in the beginning of a file, and after packet drops caused by router congestion or bit errors in for example wireless links.
* Scheduling algorithms in routers and switches. If fair queuing is not provided, users that send large packet will get higher bandwidth. Some users may be prioritized in a weighted fair queuing (WFQ) algorithm if differentiated or guaranteed quality of service (QoS) is provided.
* Ethernet "backoff" waiting time after collisions.

Answer 2

Let's first right a few matters. While hand held timing is not as correct as digital timing, however it does not provide an abilities however a drawback as a rule. One of you incorrectly mentioned that the NFL's Fastest Man pageant used to be best made from avid gamers that made the Pro Bowl. Another mistake used to be whilst anyone positioned Darrell Green's NFLFM list at four-zero. It used to be truthfully four-one million, he misplaced one whilst used to be just about 50. But shall we positioned something to leisure Darrell Green is the NFL's finest sprinter of all instances. Not best did he have sub four.two pace, he used to be nonetheless strolling sub four.four instances whilst he retired at forty yrs. historic.

Answer 3

You buy a speed...such as 5mb...thats how fast you can access it but it must be converted to bits insted of bytes because your computer doesnt ready bytes. There are 8bits in a byte so your speed gets about cut by 8x down to actuall speed.

There are 8 bits in a byte...1000 bytes in a kilobyte. 1000kb in a mb.
