50MB Questions
 

Hi all,

First post so go easy......


Had my BB upgraded to the 50MB on Saturday &.......the engineer was unable to complete it properly, got as far as the modem going in but when he phoned VM there was something called the "hits" was down????

Anyway he said I'd receive a call within 2 hrs, I didnt, had to call them and the chap managed to get me up and running; but...

Did my first test and was 47 DL 0.65UL 10m/s ping

After this one it steadily went down and down to sit around the 12 to 20 mark now.

Not had time yet to install the "N" router yet so I've run straight to the modem as they said my TP link is not compatible, lol I'll check once its all up and running.

So I called again to tell them Im not happy with the speed of 20 or less, and I have an engineer booked for Tuesday morning.

Is there anything I need to ensure he does before he leaves, not that I'd tell him his job I just want it right before he goes.

What I want you to post is the Downstream power levels including the SNR/RxMER and the Upstream power levels for me thanks.

DO NOT POST YOUR MAC ADDRESS OR SERIAL NUMBER

Is this right?

Re: 50MB Questions
 

Yes spot and so are your power levels so your speeds are a bit of a puzzler, the 6 T3's indicate possible power fluctuations internally on the modem but nothing significant.

Maybe if broadbandings views this he can add some input.

----------------------------
Try this speed test below

Here is how the speedtest works below.

click on these 2 gamefiles battlefield_2142_demo.exe and bfme2demo_english_final.exe and save them to your desktop, and then wait a couple of minutes then write down the transfer rates on the files that are running add them together then multiply them by 8 and you will get a truer download speed.

Remember to stop and delete the files.

i.e : 250Kbps X 8 = 2Mbps, 500Kbps X 8 = 4Mbps, 1250Kbps X 8 = 10Mbps, 2500Kbps X 8 = 20Mbps

Then add 10% to the final figure to account for any processes running on your computer.

Re: 50MB Questions
 

Thanks,

I ran that test yesterday and this morning and still come out with around 20

Re: 50MB Questions
 

Does your configuration page show 530000 and 175000.

Re: 50MB Questions
 

Do you mean this bit:-

Primary Downstream Service Flow
Max Traffic Rate : 53000000 bps

Primary Upstream Service Flow
Max Traffic Rate : 1750000 bps

Re: 50MB Questions
 

Yes and as you can see that says 50Mb so something is slowing you down.

Are you wireless or direct connection.

Re: 50MB Questions
 

Both,

From my wireless laptop or wired desktop which I have tried straight in to the modem and still get the same result

Re: 50MB Questions
 

Rather an odd one then as the power levels appear to be spot on, so we will have to see what the engineer says on Tuesday.

Remember to post back the results of his findings.

Re: 50MB Questions
 

Sure thing, keep you posted thanks for your help.

Re: 50MB Questions
 

I will look forward to it as it does have me wondering what the issue actually, I have a few ideas spinning around and will be interested to see what he diagnoses.

Re: 50MB Questions
 

I have just connected my laptop direct to the modem and get this now...

Re: 50MB Questions
 

Try the gamefiles above as your upload is fine and even that 40Mb is within specification.

Could be the router if the speeds drop by half when running through it.

Your power levels are perfect just check this sticky out and you will find a familiar avatar on the post.:D

ok as per virgin website i have 4 large files downloading,

365 kbps, 230kbps, 312kbps, 247kbps approx = 1154 x 8 = 9232?
