Which leaves me with Zen and IDnet to choose from?
IS THAT RIGHT?
No - Wrong!
All ADSL Max ISPs have only got BT's line length database and speed estimator to go on, and they would be foolish to use any other although it is well known that it is often way out. IDNet and Zen will see the same data as O2.
The crucial bit, which also applies to all, is
"Actual download speeds depend on different things, like the distance between your telephone exchange and your home, or the quality of your BT line. We'll work with what's there and always give you the fastest speed we can, depending on your chosen package".
That is the whole point about ADSL Max. In terms of the connection between you and the exchange, (the sync speed or connection speed or data rate - depending on what your router wants to call it), it goes as fast as possible on any particular line at any given time. As a regular poster's sig used to say, (I can't remember who and haven't seen it for a while), it goes as fast as it can and doesn't look at the estimator first.
If you look at the graph on
this page you will see it agrees pretty well with what the other one says about ADSL2+, and about 6Mbps for ADSL Max. Bear in mind that is an ISP site so they won't want to forecast too high! So I think you can assume 6-8Mbps connection, then a thing called the IP Profile comes into play, see
this table. So you should get 5-7Mbps actual maximum download. Isn't that what O2 taking a conservative viewpoint said?
And as I say, the same is universal.
My reason for the list I gave was that all those give you consistently high speeds (barring faults anywhere) within your profile. Others in the well-known ISPs have various forms of speed-limiting at various times of the day and week as they do not have sufficient kit to cope with peak demands.
O2 is top of my list because:
- although it is a 12-month minimum term there is a 30-day money-back guarantee at the start, and they have recently upgraded to cope with their rapid growth, so it should be a while before significant problems occur. It is almost certain that some slow-downs will happen in a few months, depending on further growth and BT WBC roll-out and what plans they have made wrt WBC - we have no information - and I would be pretty certain they will already be planning to deal with any slow-downs like they have in the past;
- the service is truly unlimited which could be important in your case. There is an FUP but no-one has heard of it ever being enforced;
- the price is very low for what you get, compared to the other two known quality ISPs.
