Broadband speed dropped from 49Mbps to 38Mbps over the last few months

 

Hi all,

I have noticed that when i look on the Hub Manager that my speed has dropped from 49Mbps to 44Mbps ??

When i do a speed check its actually coming back as around 37Mbps ???

My connection has always been around 49Mbps for well over a year and now its dropping lower.

Originally when i took the contract out it was showing 55Mbps then several weeks later it dropped to 49Mbps ( more of a stable line perhaps)

I am getting concerned that BT are lowering line speeds.

Any ideas please ????

Thanks

Try a hub reboot and see what happens. It might clear the cache and help reset things.

Hi,

Tried a hub reboot probably once every two weeks over the last few months but its still the same.

Hub is a new hub, master socket is decent one, all cables are in good condition.

Any other ideas ??

Thanks.

if you are not on digital voice and have home phone try dialling 17070 option 2 should be silent

can you post the stats from your hub  enter 192.168.1.254 in your browser HH6/SH2 then advanced settings then technical log information . 

have you noticed ant drops in connection apart from your 2 weekly restarts

Re: Broadband spropped from 49Mbps to 38Mbps over the last few months

from the stats the connection up time is only 4hrs is that due to manual reset or hub dropping internet connection?  from the stats your noise margin is is very high at 10.4db whereas normal should be about 6db.  if you can get down to 6db then that will give speed increase you are looking for.

however it does look like you  possibly have more drops in connections that you think and this has resulted in your connection being in a banded profile.  you need a stable connection without any drops or resets and the DLM will reduce noise margin and increase speed

did you check your line for line noise?

Re: Broadband spropped from 49Mbps to 38Mbps over the last few months

A week or two ago , not having any broadband performance issues , in a moment of boredom I had a look at router stats , being pretty close to the ‘cabinet’ , my normal sync is 80Mb , throughput 77-78Mb …the stats showed around 40Mb sync and a speed test around 37-38Mb , I had no real world issues , this  was nothing more than idle curiosity, but obviously thought that’s not right .

I logged onto ‘My BT’ to do a ‘test’ , the test came back saying something along the lines of ‘we have detected a fault outside your property ‘ , the fix date in 3 days ,  I recalled seeing a tech working at the cabinet earlier that day and suspected they had inadvertently disturbed my connection.

The very next morning , a contractor van (Kelly’s or Quinn’s working for Openreach)  pulls up outside , and knocks on the door  ….connects their tester , indicating a problem at 128 meters , the distance to the cab and leaves to visit the cab , returns 15 mins later , dis 1 leg in the cab , reconnected ….swapped out my 30 year old NTE5 for a new one and confirmed sync back at 80 Mb .

 

You can do a test yourself or call ‘faults’ and they can perform a test either way  if it indicates a problem (as mine did ) Openreach are advised and if my experience was anything to go by, it’s a pretty quick response.

As you have no phone then check the hub event log and look for drops in connection and restarts  your stats suggest it is often

Why do you restart hub every 2 weeks?

I restart my hub every 2 weeks hoping it may get back to 49Mbps like it was on the old ays.
