Infinity speeds 15 Mbps lower than expected

Hi all,

 

I had Infinity 2 installed on the 26th March 2013.

 

BT.com/Infinity show I can get "59Mb Download speed" and "20Mb Upload Speed", while ADSL shows "6Mb estimate download speed, 4Mb-8Mb Download speed range". 

 

In reality I was reliably getting 12 Mbps for some reason... (on ADSL).

 

 

Once I got Infinity 2 installed, I seem to be only getting about 42Mbps reliably. Very occasionally I can get ~48Mbps on various speed tests.

 

Looking at the modem stats, I see a very high amount of CRC errors.

 

System up time

3 days 23 hours 12 minutes 5 seconds

CRC errors

50329 

 

 

I suspect these errors are causing my connection to not be as high as it should be.

 

 

I had Infinity 2 in a previous property, and download speed was 'promised' at 66.8Mbps, but in reality I was getting full 80Mbps.

 

How do I get my full 59Mbps, because currently it's almost not worth paying the extra for Infinity 2 when I am not getting much better than Infinity 1 speeds?

Yours errors are not high and are nothing to worry about it.

Looks like you're using an unlocked Huawei and the stats are from the GUI.

 

There maybe an error with the display as if you telnet into it those CRC errors are shown as FEC errors & vice versa. Gives a totally different picture.

Re: Infinity speeds 15 Mbps lower than expected

Thanks TimCurtis,

 

Will verify this once I get home.

 

 

As for the "Up To" service, it's "up to 76Mbps" but the number checkers all state pretty you will get 59Mbps - it doesn't state anywhere that those are an estimate or you will get within a range, as it does with ADSL. 

 

I just want to make sure I am getting what I am paying for, or else I may as well try and 'downgrade' to the 40Mbps service.

Quite a lot of "up to's" mentioned there. 

 

Although no "up to" mentioned when you put your number in on the bt site to see what speed you will get

on the same page the t&c's mention it is an estimated speed.

BT always offers you the best speed possible on your line. The speed prediction we have given here is an estimate, however download speeds can vary and the actual download speed will fall within a range. The BT broadband range is an indication of the speed that other similar lines across the UK have achieved for their broadband service; this is generally within 1-2 Mb higher or lower than your single estimated speed quoted for BT broadband.

The actual speed is dependent on several factors such as the product option you choose, the processing power of your computer, how many people are using your broadband connection at the same time, whether you use a wireless or cable connection, the speed of the websites that you visit and the performance of our network. Speeds can be lower at peak times – peak times are evenings and weekends.



And its also mentioned as "up to" on the product details pages.

Re: Infinity speeds 15 Mbps lower than expected

Once you have started a telnet session (via 'tenet 192.168.1.1'), the username is 'admin' & password is also 'admin' (without the quotes).

 

at the next prompt type 'sh' & then at the next prompt type 'xdslcmd info --stats' (all without the quotes).

 

You should then get something like this:-
