BT FTTP 900 download speed really low (6mbps) upload is fine (110mbps)

Hi,

Need help..

I am having a really weird issue with my connection..

My FTTP 900/110 package is producing speeds like 6mbps download and 110mbps upload 
it just so happened the problem occurred during out of hours. 
I do use my own kit but I have put back in the hub which was supplied when I took out the FTTP package back in December and the problem is still there sub 10mbps download and upload is fine..

I have done the reset steps and troubleshooting call/line reset however the problem still persists. 
There is nothing I can do my end that I haven't already done so I guess its your end that is the problem. 
Need help Thanks

Run a test from the mybt app. It will tell you the speed going into the hub.

Are you connected direct to ONT with ethernet cable to your pc. Are you using powerline adapters and if so try without them. Run btspeedtester. Or try fast.com and see speed

Hi, I have Ethernet cable connected from the ONT [CAT 6A]- > back of [AX89X] router. Tested it with SH2 and now back with AX89X.

iperf3 tester script:

iperf Done.

Result.

WoW. Peek speed: 947 Mbit/sec
Your Bandwidth is: 919 Mbits/sec

It looks like the speed issue has resolved itself.. However I will keep this post open for a little while longer.



Regards previous post SH2 connection stated 1000/1000..

Re: BT FTTP 900 download speed really low (6mbps) upload is fine (110mbps)

Hi,
At the time I was trying to resolve this speed issue using BT apps I was greeted with "Sorry cannot find your Account " please call 0800 800 150 when I was doing test via myBT  and the only way I could see line state was via the SH2 GUI locally which showed 1000/1000..

I was unable to even log this as a fault as it was out of hours, at the time.. 

speedtest.btwholesale.com was showing random speeds way below normal single threat tests such as 260mbps Down / 112mbps Up

speedtest.net was showing sub 10mbps down and 110up

My AX89X router has inbuilt speedtest based on ookla service which again was showing similar speeds sub 10mbps range on downside

my own iperf3 tests complete during this time were also showing very erratic speed results well outside normal deviation speedtests Inormally run confirming that there was issue with *something* outside of my control

Now, as I have reinstated my original setup (AX89X is back in) I dont want to unplug and swap to SH2 for sync rate stats as my line is currently looking "ok" atm, and ofc. cannot use myBT app if no SH2 installed.. Greeted with "Restart your Hub" message in a Yellow box

The  only sync speed you will get from the hub is that between the ONT and hub. The line sync speeds are held by the ONT which is not accessable.
