Slow Bt Infinity

Hi guys, hope you can help or point me in the right direction. I got Infinity las Feburary and i thought it was slow , someone on this forum help me fix it by giving me details of TCP optimizer ( i use xp), worked a treat.

last week my BB dropped dramatically , I went to the bt speed test website and some times the download speed is zero ,most of the time the rate is below 10, also some times the ping is zero also. Even when the dowlaod speed is zero i'm stilll connected to the net . My PC is a wired system , so i took the erthernet cable out off the back of the PC and connected to a laptop .. same results.

BT BB engineer came today and said the line was fine , no faults and running at 80mbs , but both PC and laptop still running the same, in fact trying to open this site took 4 mins after i signed in .

Any ideas guys what i can do to fix this?

Re: Slow Bt Infinity

Run the performance test at www.speedtest.btwholesale.com then go on to do the Further Diagnostics. This should then tell you what your IP Profile is. You really need to know your IP Profile to get any further.

Re: Slow Bt Infinity

When you select the Further Diagnostics, it asks you for the Telephone Number of the broadband circuit and you just enter your BT number.

Re: Slow Bt Infinity

I think you went past the IP Profile and went on to do a TAP 3 test.

Re: Slow Bt Infinity

The existence of the TAP 3 test shows you have a problem that you should contact your ISP about.

Re: Slow Bt Infinity

That profile is excellent.  What download/upload speeds did the test give?

I see you are running wired, so that shouldn't be the issue.

 

It might be worth ruling out HomeHub problems.

Try connecting a PC or Mac directly to the modem: a bit of a faffle I am afraid.

- connect from the modem LAN1 (that is usually connected to the HomeHub/router), to the standard ethernet port on the PC/Mac (that is also usually connected to the router.) So the HomeHub is out of the picture.
- Make a pppoe connection. On a PC it will be something like
- 'network and Sharing Centre',
- 'Set up a new connection',
- 'Connect to the Internet, set up a broadband or dial-up connection'
- 'Broadband PPPoE'
- Then enter username 'bthomehub@btbroadband.com' and password 'bt'.
Detail may vary a little between different version of windows, and of course even more different on Mac or Linux.

Repeat your speed tests and see how they go.
That will help check out if the HomeHub is the problem.
