Fibre 900 Download Speed > what should I expect?

bionicmanc — Tue, 21 Dec 2021 13:32:21 GMT

I had FF900 installed 3 days ago. Upload speeds are constantly around 100mbps but downloads are usually between 250mbps and 350mbps (sometimes but rarely in the 400s and sometimes in the 100s). Is there a period of time where it will increase until finding a "stable" maximum speed? Not sure how these things work but reading through these threads most seem to be getting 2 to 3 times the speed I'm getting.

Any advice welcome...thanks!

@bionicmanc

Your speed will depend on how many other customers are sharing your backhaul link, as you do not have a exclusive connection. There is no settling in period.

You will only get the maximum speed available at the time, on an Ethernet connected device which has a 1GB network card.

Thanks for the quick reply. So if they guarantee 450mbps and I'm not getting that I should contact them now?

For my information, do you know how many others I could be sharing with? And if the impact is so significant on my download speed, why would my upload speed not be impacted?

Thanks again!

Download speeds will be device and connection type (wifi/ethernet) dependent.

Speed guarantees are essentially speed to the Hub.

How are you testing your speeds? Which devices etc.

I'm speed testing on my laptop which is connected to the Smart Hub by ethernet.

I've tried Google Internet Speed Test, fast.com and Ookla (all with varying results, Ookla seems like a random number generator!) but they are rarely getting into the 400+mbps and I've never seen 500+mbps in all my tests. Which one do you recommend?

I did try the BT Troubleshooter and Speed tester but it says "Sorry, we're unable to test your speed at the moment."

If speed guarantees are to the Hub (do you mean my Smart Hub?) and the WAN Link Speed says it's 1000Mbps, surely if I'm getting 200-300mbps one metre down an ethernet cable that's a hell of a drop?

BT's FTTP team recommend Fast.com.

32 connections share a 2.5Gbps backhaul link, but 2 are usually left spare, so 29 others.

Because there is far more download capacity in use than upload. The vast majority of upload traffic is just acknowledgement frames from download traffic rather than actual upload traffic.
