Down NM was 1dB only once as reported, but has been 3dB ever since. May be too early to call.

I think im going to get a second line and do the sharedband thing to get better speeds.

Why? What speed are you trying to improve? Why do you need faster upstream? It won't help streaming. Is there some other use, that you haven't mentioned as far as I can tell, that you need faster?

Whatever it is, surely it is better to see why you aren't getting it now, rather than spend money and find the same problem still exists?

There is, however, an extension fitted to it (behind the socket) that was put in by our builder...

In reply to a post by mungler:

I actually did just unscrew the filtered faceplate and plugged in via a 'dangly' microfilter.

But you haven't answered the following question (preferably with pictures);

In reply to a post by XRaySpeX:

Remove the filtered faceplate by the 2 screws. Are there any wires connected to the terminals on its reverse?

If the extension socket continues to work after you've removed the filtered faceplate, you've located the problem.

Yes, you're right - the second line / increased upload is really because I work from home, and quite often have to upload large files. What prompted my frustration the other day was an upload of a ~2GB virtual machine image that just took forever, and kept timing out etc.

I understand faster upstream wont help streaming - sorry, it was a bit offtopic really.

Going to hit the hay now - thanks for all the help!

There were wires connected to the part that came off when I unscrewed the faceplate, yes. Four, I think, in total. I have the modem hooked directly to the test socket now.

Find out about annex m may double upstream speed but drop downstream slightly.

As for iplayer is it just iplayer or does youtube suffer?

Are speeds sustained, the graphs on our speedtest will show that http://www.thinkbroadband.com/speedtest

As you now know a stable line can be sync'd at 3dB.

It is quite possible for the SNR to actually drop to a negative level - I have seen -0.7dB on mine. And it would stay synced for week/months

I did manage to capture a screen shot at 0.5dB. Mgn1 is the sync SNR, Mgn2 the snapshot SNR with the last being 0.5dB.

Have a look at SNR variation over a day to see how much it can move.

Hi Andrew,

Thanks - I have already requested Annex M as well as a regrade to a business plan from my provider which has lower contention, so hopefully that'll be my home working problem sorted out.

I ran your speed test - here's the result: http://d.pr/i/mZTL

Im not really that sure how to interpret the results, but it looks ok... I guess?

Results do NOT look good.

The two download lines should be very close, and your latency was high too. If this was done over an Ethernet connection, then I would be tempted to suggest that maybe some ISP congestion is sneaking in, and combined with the iPlayer comments that looks to be the case.

BTW no need to bother with droplr our test lets you link to the images of the result (below the main test window is a URL).

If it was me I would be looking for a different provider and not a different contention product.

Hi Andrew,

Sorry, I tested via our wifi (802.11N 5Ghz via Airport Extreme 2012). I guess I should plug in to the router and try again, right?

Thanks

I always like to try an alternative router/modem before coming to any conclusions or proceeding any further, even if that only verifies that the current router/modem is working OK
