pags,

I too always use 10 bits per byte when comparing these numbers.

For me, it comes from the early days when everything was via serial modems.

The bits per second was the actual bit rate of the link and bytes per second was the number of actual bytes transferred per second after the overhead of the link.

The typical overhead was to add a start bit and a stop bit to an eight bit data byte.

I have found that on my ADSL connection, the factor of ten still gets me very close to actual bytes transferred. And it is a lot easier to do in my head.

Not bad for a usb modem with a max of 3.0 MBs per second .

Yes, I started that on serial modems also (started at 110 baud).

Note, that baud is not actually bps, but the measure of how often the tone frequency was changed per second (IIRC) (although they are considered "close enough" to end up being used more or less interchangeably.  I just found that the divide by 10 generally still held (holds) true for Ethernet/LAN/WAN (again, due to protocol overhead, TCP and IP packet encapsulation, etc)...

"The test shows higher than 0.5mb but these sort of tests probably aren't too accurate."

no, it is accurate, most companies will say that they can offer you 1 mbit maximum but it is a average guaranteed of 70% of that only but sometimes you can get 120% or more, i had a service that gave me always 15% more than it should give, in my case it reports 30kbs less but in upload is correct, most connections are 10 to 1 in download/upload or 24 to 1 but in your case it's almost 1 to 1

horrible service

is it a broadband over phone line? 

time to try other service, even 3G is faster sometimes

Hello,
         Yes it is over a phone line.Unfortunately BT are responsible for the line to the exchange and unless they are willing to improve or replace it which they aren't, using another service provider will change nothing. BT is still the company that has all the control.The 0.5Mbs is from data provided by BT Outreach(same company) and is what service providers quote when they check your lines suitability.

If there's a harder way to do something I'll probably find it.

you keep talking about lines, phone lines are horrible, cablemodem is a better solution here

most of us do not have the option of cable and have to use what is available.

You're presuming he has access to the Internet from a local cable provider (or that is available at all in the UK...I don't know, I'm in Canada  ;) ).

And phone lines are not inherently horrible, the state of the existing infrastructure is (which he states as belonging to BT).

I have DSL over phone line, and have a 5Mbps service, and it's working well for me (touch wood!).  I can even remote into my residence from work (for instance) and run X programs (such as Synaptic, of Thunderbird), and while I wouldn't want to to that all the time, it is usable.  So, that would indicate that my asynchronous upload isn't too bad, either (of course, if I could have more bandwidth for less money, I'd take it!  Always willing too want more...it's human!)
 ;D

i don't know what he has there(in in south america, better service here  ;D   :P), that is why i keep asking and suggesting ideas, that is why the forum exist, let us make questions and also get answers  ;)

phone lines most times are horrible for internet service, this is another proof of this

about options, wifi, broadband and 3G or4G are options here

there is options always, i don't even have a phone line, i have a virtual line over the broadband cable modem, it works very well and the price is very cheap, i decided to dump the old line because i hate it and how it works, the price and the low quality, the new service is not perfect but is at least 5 times better than the old one

there must be options, it is not possible you can't get another service with other company

That is the point you seem to miss .......... your statement is not true for everyone. That it is true for you is no help to someone who has no options.

that is the most pessimistic answer i had seen in this forum!

all you say is that there is no hope and you have to suck it up!

no, there is always options, you could not use internet again  ;D

Hahaha, if you call the option "waiting for better times" a option, you are right!  ;D
And believe me, I just have to move 40 Km's from where I live (where I got plenty options) to be at a spot where is NO option at all so far.... And no, its not a place where no-one lives, plenty people live there.  "Option-less" exists!!  (AKA no options)  :D  Other places offer just one option at best. It is depending as to where you live/are.
Hard to imagine?

no, i can imagine it, 5 years ago i only had phone line but right now i have 3 options apart from the phone line

most times you need to talk with the company and show your interest for the product they offer, if there is not demand in a specific are, there will be no offer, they won't wider their current network and won't sell more connections

sometimes you can create a local wifi with wide coverage using a faster connection covering 1 to 5 kilometers, sounds like a project to collaborate with the neighbors
