BT GFAST going slow and intermittent

ssrivast12 — Sun, 04 Jul 2021 09:54:02 GMT

I ordered GFAST in March &used to get 200Mbps d/l & 30mbps u/l. After an engineer visit he changed ports and now it's constantly going down & is 150 / 24 mbps. My neighbour still gets 195/29. BT support. says no fault /no help. What is the best way to get back original speed & what my neighbour is getting. I should not be checking fiull day what speed I am getting. At times I am getting 100/ 15 mbps but by the time you call them its back to 150mbps which is minimum guarantee so no support.

Was wondering if someone here can help and get some consistency in speed...

My neighbour seems to be happy and never complain about speed. Seems like I am paying extra 25 pound for a service which is not as reliable as I was told and thought of.

Can someone help ?

Thanks in Advance.

Can you post your router stats from Advanced settings/technical log/information.

Check for noise on your line. 17070 option 2, best with corded phone, you may get a background hum with cordless.

The connection speed will not change, however the download speed will vary depending on how many people are using the backhaul connection to the cabinet, as its shared between all users.

So if its the download speed that you are measuring, then that explains the variation.

Also, if you are measuring over a wireless connection, then that will be all over the place, due to the amount of interference.

This is what my package says

I agree. I have measured with speed with a cable connection to desktop as well. However, in any case ...BT Check on App should not change " Speed to HUB". ... BT Guarantees "Speed to HUB" which is the concern here. Internal connection ..devices,... wireless etc can be a reason.. but I am asking why " Speed to hub " is fluctuating.

ssrivast12 — Sun, 04 Jul 2021 12:02:41 GMT

This is latest Just now. 149 /25 to the hub ...which is below the guaranteed....

Re: BT GFAST going slow and intermittent

The speed to the hub will vary, depending on the number of customers connected.

Your physical connection (sync) speed will remain fairly constant, as that is dependent on the actual line conditions, which should not change very much, unless there is a line fault.

So...looks like there is a big fluctuation ... as you can see its 149/192/182 ..etc etc.. and 24/27...

Shall I report a line fault and ask them to come and investigate ?

As the speed to your hub at the moment is 183mbs, its above the guaranteed minimum speed of 150mbs.

Overall connection speeds are likely to drop, as more customers get connected, and crosstalk is increased. You may have been getting a faster speed before, but that is no longer possible.
