3 months of endless dropped connections, yet BT say there's not a fault

Can I send you tech log of smarthub 4 please 😏  We are on copper adsl, about 3km from exchange.   Eventually found out from one of many engineers that the SH2 is no good for us, so we are trying to use HH4, but it's just as atrocious.

Re: 3 months of endless dropped connections, yet BT say there's not a fault

Hi @Itsover welcome to the community and thanks for posting, I'm sorry to see you're having issues with your broadband. The log isn't showing any drops it's just showing the firewall is blocking incoming packets which means it's doing its job.

Do you have any noise on your landline? If you do the quiet line test by dialling 17070 and choose Option 2 it should be silent. 

Thanks

Neil

Thanks for your reply. Quiet line test is OK.
I couldn't send the whole log obviously.... for instance, there were several instances of PPPoA is down, what would that mean, please - normal or not?
Unfortunately the broadband has been so bad the last few days that we've had to resort to using our linksys router again, which is a great improvement but not a cure

Just for clarity, when you say the firewall is doing its job, I assume you mean it's doing its job correctly? It seemed to be blocking everything on Saturday, even with an ethernet cable running from router to laptop.

Can you post connection stats from your router. Have you tried using the test with a filter to see if that improves stability

Enter your phone number and post results remember to deletnumber

Sorry, I completely forgot to mention that these tests are done using the linksys router - the one below was done using a filter

The premise/line is associated with exchange which is NOT part of current fibre priority programme.

The premise/line is associated with exchange where WLR is not withdrawn.

The premise/line is associated with exchange where SOADSL service is restricted.

 

 

FTTP is not available.

You are. Currently on adslmax a d may be able to upgrade to adsl2 which would probably give you an increase in down speed but definitely an increase in up speed

Do you want the HH4 connection stats, or are they the same as will be om linksys router? Sorry, I'm more than a bit thick...
