Re: Mismatch between "Minimum speed guarantee" and actual

Essentially, yes.

As above though, there may be no fault. It may be that your line is not matching the standard values used for the estimated speed calculation.

Re: Mismatch between "Minimum speed guarantee" and actual

The second engineer visit didn't improve anything. He did reset the DLM which boosted speed up to 38 Mbps temporarily but it's back to 34.88 now. Apart from that, he said there was nothing that could be done.

 

I did find out that we are 700m metres from the cabinet, not 100 as I thought. The cabinet is located at the local exchange.

 

I think I'm flogging a dead horse trying to get anything close to 49 Mbps.

Re: Mismatch between "Minimum speed guarantee" and actual

The speed of your connection will vary depending on the distance to the fibre cabinet that serves your house.

We are 450m metres from the cabinet, and get 55 Mbps max. That's why we changed down from Infinity 2 to Infinity 1,

still getting 55 Mbps on a guaranteed 52 Mbps line!

 

There are loads of distance against speed graphs available online, but why not try: https://availability.samknows.com/broadband/broadband_checker

 

For our connection this shows:

You are connected to the xxxxx telephone exchange.

  • FTTC is available in your area


Downstream Min: 44.5 Mbps
Downstream Max: 61.8 Mbps
Upstream Min: 12 Mbps
Upstream Max: 18 Mbps

 

Also, are you using the BT Home Hub range or a 3rd party modem router?

We found that initially Draytek provided better downlink performance then Zyxel better again still!

John, I actually posted the results from the BT DSL tester on the previous page...
 
 
Distance measured from my front door to the cabinet at the exchange (up the road and round the corner) is just short of 500 metres, not 700. The last 100 metres is on poles though, as is the electricity supply, so that may make a difference.

Re: Mismatch between "Minimum speed guarantee" and actual

An update.

 

I am now getting just over the 48 Mbps minimum guaranteed download speed with 48 to 50. I'm not sure when this happened and it wasn't as a result of any action by me. Maybe some wires have been unscrambled somewhere. However, I'm not complaining.
