Hoping for a bit of help on this one from the MODS.
I work in IT and have done for 28 years. Part of that time was spent being a network engineer so I "know my onions". The speed tests I refer to below were from fast.com / speedtest.com / BT
I ordered Ultrafast 900 from BT and Openreach duly turned up to install the ONT and run the fibre. He plugged in the Smart Hub 2 and told me I was live and ready to go. I didn't check speeds as with it being Fibre I just expected it to work out of the box - This was a mistake.
I connected my laptop later on that day to test out the connection. This as directly into the Smart Hub via a Gig Ethernet network card. However, speeds were nowhere near the advertised rates. I was getting the following results
I decided to discard the hub and plugged my laptop directly into the ONT, setup the connection and ran a series of speed tests.
I then plugged the Smart Hub back in to see what results I had.
Upload 50-52 - Not sure if this related to another thread I've just read about throttling being active on the Smart Hub 2.
I then ran the BT speedtest that you can access via the Smart Hub 2. According to that, I was getting
I called BT to raise a fault and was told they would send an OpenReqch engineer round. He checked the light coming down the cable, said that it was excellent so no issues there. He switched out the ONT just in case that was faulty but it didn't make any difference. We also replaced the network cables we were using. He couldn't get anything faster than I had (directly connected to the ONT). There were also no faults on the ONT at the management end.
I contacted BT again and they said the Openreach engineer had closed down the ticket as they were happy with the installation. BT re-ran their speedtests and are adamant that I'm getting the throughput below
BT have now said they'll send Openreach around again but they're just going to say everything is okay with the installation.
By connecting directly to the ONT via Gig E, I have ruled out it being anything in the house so it's definitely either BT or Openreach.
Can one of the BT mods in here get this escalated as I'm paying for a service BT say I'm getting, but in the real world I'm not getting the stay fast guarantee.
Solved! Go to Solution.
Hi @symbol-soup welcome to the community and thanks for posting, I'm sorry to see you're having problems with your FTTP broadband speeds. The stay fast guarantee is to your Hub and not the device and this is where the MyBT speed test measures the speeds from. There does appear to be an issue with the upload speed and we should be able to assist you with that and we'll be happy to check over the connection.
I'll send you a private message so you can get in touch with the moderation team, you'll get the private message by clicking on the envelope in the top right of the community.
Thanks @NeilO . I appreciate you looking at the upload speeds. Your answer about speeds to the hub doesn't really answer my question as to why I'm only seeing 350 meg downloads when I'm directly connected to the ONT though.
Also note the helpful points in the drop down on @pippincp 's recommended test page.
When testing 500Mb/1000Mb speeds via a computer based device the results are dependent on the capability of the device and the premises environment.
In addition to the standard guidance provided in the ‘Before You Start?’ section you need to ensure that the customers device meets the following minimum specification:
NB: To ensure accurate results please ensure you are testing via a wired connection with all other devices disabled, or switched off when running the test.
Thanks for this but my equipment exceeds all of those specs. The mods have been in touch so I'll post on here once there are some updates.
Have you tried a second machine connected hard-wired?
Have you proved that your laptop ethernet port is capable of transferring data at gigabit speeds (perhaps from an internal source/server - some aren't, depending how cheap the manufacturer was with the chipset/bus architecture)?
I had some luck on one machine that was performing poorly by running TCPOptimizer. I suspect something had screwed with the ipstack settings somewhere along the line. A fresh build of Windows 10 didn't need tweaking to perform at the maximum throughput.
