Unreliable broadband

Hi Since we moved from solid 8mb ADsl to 17mb ADSL2 about 2 years ago i have been getting loss of internet and drops in connections and Vo4 errors on  BT Vision box every few months.Line tests ok and about 6 engineers ( Broadband Boost) have been out and never found a problem.They have done a lift and shift in the exchange,new underground cables changed out, new home hub 3, new nte 2000 linebox and cat 5 data cable direct to router and a RFI filter fitted. blue light does not go off when loss of internet or slow connections, but i can ping when it happens.The only thing not changed is supplier. stats from router below router swopped with my business broadband to see it it changes.

Re: Unreliable broadband

Hi Welcome to the forums
Here are some help pages done by CL Keith

Can you also post the full results fromBT Speedtest
Have you tried connecting to the test socket at the rear of the master socketTest Socket.jpg
Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal

Then someone here may be able to help and offer more advice.

This is a customer to customer self help forum the only BT presence here are the forum moderators

We were unable to identify any performance problem with your service at this time. It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly. If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.

Re: Unreliable broadband

your hub errors are very high for your connection time which is indicating some noise on the line which may cause disconnections and affect your throughput these need
to be reduced
I suggest you look at the interference pat of the link I posted for some possible ideas
