Heavy BufferBloat on BT900 : 2.5-3.5 on Quality Metrics = congestion

Go to solution

Hi,

I have had BT900 for 6 days now, it's been great having some extra speed, but I'm experiencing poor BUFFERBLOAT on the ThinkBroadBand Speedtests (and for me, only one that has enough bandwidth for testing MY Gbit connection to its max, when others are getting a full whack on speedtest.net - I'm not on any servers local to me or far away),

my previous ISP Plusnet was always 0.1 quality metric every time, but right now, even at 4 am when it should be dead quiet, I'm getting 2.5-3.5 on bufferbloat which it states is very poor (worse than Wi-Fi, and this is on LAN), and my speed maxes out at 700ish on speedtest.net and on Think Broadband's various tests varies between 600-800 (with 800-900 bursts) with 3.5 bufferbloat metrics - this can't be normal for a full-fibre connection surely>?

as I see people posting SPEEDTEST.NET speed tests on BT900 with 7ms ping and 900Mbps on the head, my ping is 22ms like VDSL and I ain't hitting 900 at all on that site, at 4 am too!! - I will test it during the day and peak hours from now on. Even TBBx1 is below my MGALS of 455Mbps

I also opted out of BT-Wifi-X days ago and it still showing on my Wi-Fi.

GRADE 3 = CONGESTION MAY BE AFFECTING SPEEDS

im still only getting about 60% of the bandwidth I'm paying for with pings that are similar to VDSL (20-30ms) when on full FTTP they should be under 15ms at the most

there is obviously some bandwidth issues in my area that needs addressing by BT Openreach - as a new customer I do get 28 days to decide if I'm staying or not, as my experience so far has been mediocre compared with all the other ISPs I've been with.
sites blocked etc.. HAVE to use a VPN to access certain sites - without they are blocked even with encrypted coudflare DNS - had nothing like that on Plusnet.

FTTP is a heavily contended service, up to 32 users can be sharing the 2.5Gbps backhaul. It will be exactly the same contention whichever provider you use.

It has been posted here and on Kitz numerous times.

Why do you think it is so cheap compared to a leased line?

You are joking of course, unless you have lots of money, and want to pay for a business connection 😀
