Download speed degradation

When our village had FTTC enabled in July, I switched from ADSL2+ to BT Infinity 2. At first the speed was not too bad but being 500m from the cab I guess 54/8 is to be expected, but now its down to this:

The upload actually seems to have got slightly better but the download has gotten a lot worse. What could be the cause of this? Increased crosstalk due to more users signing up? It's a bit disappointing as basically I'm getting Infinity 1 speeds at Infinity 2 prices...

Do you have G.INP ?

Seems like crosstalk is the issue, BT should let you downgrade to Infinity 1.

What are the estimates for your line, yo can find these at the BT Wholesale Checker by entering your phone number or full address

Currently (although they were higher when I signed up):

For all ADSL and WBC Fibre to the Cabinet (FTTC or WBC SOGEA) services, the stable line rate will be determined during the first 10 days of service usage.

This line has jumpers in place.

How do I find that out? I have a HH5 which does seem to give much useful info...

First, find out if your cabinet is a Huawei or an ECI http://www.kitz.co.uk/adsl/cabinet-lookup.htm
If it's an ECI it currently doesn't offer G.INP.

Then check your modem. There's a label on the bottom.
If it's a HH5 Type A, it doesn't support G.INP. If it's a HH5 Type B, it does.

On Infinity 1 your speedtest result would be 38.7Mbps absolute tops. Upstream probably unchanged.

All I can suggest is asking BT to be downgraded to Infinity 1 then

Where does it say it? In its GUI, or telnet output?

Thanks BatBoy,

It looks like a Huawei. Cab 2 in Chinnor. And I have a HH5 type A.

Question is will BT allow me to downgrade as effectively I renewed a contract with them in July...
