BT 900 slow speed

Hi all, 

I had BT 900 broadband installed yesterday and when I run a speed test I'm getting about 90mbps not the 900mbps or 450mbps which is the guaranteed speed. Has anyone else had this problem and know how to fix it? I tried calling the helpline but gave up after 48 minutes on hold!

Re: BT 900 slow speed

How are you testing your speed, wired or wireless? Which speed test are you using? Fast.com is recommended for an ethernet connection.

Possibly a confusion between megabits and megabytes per second?

@Keith_Beddoe  Possibly that's why I asked how and which test .

Thanks but there's no confusion they advertised and sold me BT 900 the fastest connection in the UK and I'm getting BT 900 the most mediocre connection in the UK. I previous had virgin 100mbsp and it averaged at 110mbps, this connection isn't even close to thoes speeds and is only 10% of what has been promised.

Hi thanks for the quick reply, I'm testing on WIFI using speed test pro. I know a wired connection would be faster but 810mbps faster?? It can't be that different surely.

Let us know when you've done a wired test.

Hi, I ran a wired test and got between 600mbps and 940mbps this was using fast.com when I unplugged the ethernet cable and tested WIFI I was getting around 60mbps to 110mbps. Any idea why the WIFI is running so slowly?
