Capped broadband speed after major fault on line

Go to solution

Hello, I'm a long-term BT customer but a recent BT Broadband customer, using a BT Home Hub 3 type A. Since the fault on my line has been fixed, my broadband download speed appears suspiciouly constant at 1152 - see below. I write 'suspiciously' as, whilst the fault was being fixed, my Broadband speed (when available) dropped as low as 240-ish but as high as 1890+ so my line is clearly capable of delivering a higher throughput than I'm getting.

 

My neighbour's Broadband (also with BT, also using a Home Hub 3) appears faster than mine, around twice as fast when we both recently downloaded the same iPhone update, but I haven't done a speed test on his line.

 

It appears from other posts that BT cap broadband speed after repeated disconnects (caused by my line fault that BT have now fixed), but don't seem to quickly uncap the broadband top speed.

 

Any ideas?

Hi could you also post the connection time and connection speed from your adsl stats

Re: Capped broadband speed after major fault on line

Well, so far my router has behaved oddly twice - it slows right down (e.g. 15-20 secs to display event log page), shows that broadband is connected - yet all websites timeout. The WiFi network remains up, so it's not a total HH3 router crash.

This odd behaviour lasts for about 30 mins, then all comes back, and line speed has changed. It got as high as 2.1Mbps but has since sunk down to 1.781 (see below).
It would be great to get the 2.1Mbps back... I notice the latency type changed from 'fast' to 'interleaved' too.

What sort of speed should I be expecting?


Simon.

check your possible speed on a good line here

check speed

 

are you connected to the master or preferably the test socket?

You have a very high number of errors showing for such a short connection time using the test socket will eliminate any internal wiring problems

Unfortunately I am using the test socket... and the speed has now dropped to 1.5 Mbps
