I have an 8MB broadband service but I've had a terribly slow connection (close to dial-up speed) with a regular loss of connection for over a month. Before this problem started, my IP Profile usually averaged around 5000 kbps; it has been stuck at 135 kbps for over 4 weeks with an IP throughput of around 10 kbps.
I replaced my internal phone extension cable, router and filters and have used the test socket as well as the master socket on several occasions.
I've reported a fault with both BT (British Telecom) and my ISP's Home/Office Support technical advisors on several occasions. I had been experiencing a hissing and crackling noise on my phone line for several months - the noise seemed to have gone in the last few days, but has now returned today.
A BT engineer was going to visit my house, but one of my ISP's technical advisors told me to cancel the visit and leave my current setup for a few days. The good news was that 2 days later my IP Profile finally rose back to 5000 kbps but my IP throughput remained at around 10 kbps. I got through to the same technical advisor, and he reported the fault to BT again. Yesterday evening (23 July) I finally started to get faster speeds until my connection cut out at around 10pm. I rebooted the router and found that the connection speed had slowed down once again. My IP profile is now 3500 kbps with an IP throughput of 43 kbps.
My DSL connection is usually around 3000 - 5500 kbps. Why is my IP throughput so low?
I've gone onto various forums and one answer that I found was this :
What you have here is a fault b-RAS, which is the result of a faulty line card issue at the exchange. What you need to get your ISP to insist on what is called "Lift and Shift" with BT Openreach which will get your line changed to a different line card, which will resolve the throughput problem."
Is this good advice or should I do something else? Please help because this problem has been going on for weeks and there has been little sign of a solution.
