No-one will close the thread, it'll just sit here until your reply.
re: message 194

Don't forget that a connection to the original, end of extension line, position caused a 60% drop in speed  - maybe whatever is causing this degradation is also affecting the faceplate connection (back emf?).

There's no "back emf" here! If you are meaning connecting to the normal face plate socket, with the extension wiring that's now giving a problem still connected to the faceplate, then it will cause the same issue. Only connecting to the "test-socket" behind removes everything internal from the equation.

Re: Broadband dropouts

Well, here's a warning: most of our travelling is over and I'm slowly getting back to this mind numbing problem.

I haven't touched any connections yet, the following is merely a set of observations.

On return from a few weeks away I checked the connection with BT Wholesale (BTW) with these results prefaced by a few in June:-

IP Profile/down/up and ms = master socket (at first floor location otherwise):-

June

6, ms - 17.52/16.55/0.97

12 - 17.04/14.2/0.39

August

11 - 18.97/13.02/0.44

September

6 - 18.78/7.03/0.51

7 - 20.18/10.49/0.40

17 @ 14.01 - n/a/12.03/0.42 (n/a = BTW unable to access further diagnostics)

17 @ 14.04 - 19.74/10.77/0.43

17 @ 14.08 - n/a/7.71/0.43

BTW is my preferred test but in addition today I ran:-

Ookla: 17.67 down/0.99 up (this is patently incorrect)

thinkbroadband: av TBB d/l 8.34, av u/l 0.65 (closer to real life experience)

Edit at 15.31:- (thinkbroadband test rerun at 15.25 giving av TBB d/l of 17.72 which they say equates to their old standard test. But the first thing that came up (before I clicked a link to full results) this time was a graph showing d/l 6.5 which is the HTTP x 6 full result figure. I reran this test and the HTTP x 6 figure was 17.99. I was streaming two internet radio streams at the time.). 

The real life experience is that internet browsing is OK if at times slow to load pages but TV streaming (not PC) via wifi is impossible without severe buffering (before the Dec 15 BB failure TV streaming was perfect).

In the next few days I shall try the following "hard" line checks:-

1. master socket BTW tests, router next to it on ground floor

2. first floor extension socket tests with router connected here

3. computer room tests - standard

4. as 3 but bypassing Belkin surge protection

5. as 1 but long cable to router on first floor in standard location

6. long cable from front of master socket

Somewhere a difference might show up.

 

Edit at 16.09:-

My son pointed me in the direction of thinkBB's large file d/l page. Two d/ls of 100Mb and 200Mb gave near identical results that using their timings give an interpolated d/l speed c.18mbps. Thoughts?

Re: Broadband dropouts

Update

Non BTW speed tests still giving c.18mbps (e.g. Ookla app on iPad via wifi).

BTW gives 11 (on PC ethernet/router connection).

Why is BTW (probably) wrong?

I say probably because the large file d/l check agrees with the other tests and (fingers crossed) BB is stable and reasonably quick.

Re: Broadband dropouts

Does nobody have any idea why two tests have such a wide discrepancy?

Ookla result attached.

Fingers crossed, we may be drawing this thread to a close. I'll keep testing for another week but ITM - anyone?

Re: Broadband dropouts

No response: somewhat disappointing.

 

Btw, 2 total BB dropouts in last 10 mins.
