Slow Speeds

[UseOnceDestroy]

Hi,

This is the first time I have posted i this forum so apologies if the information I provide is incorrect.

I have been experiencing really slow speeds for a long time, I used to get an absolute minimum of 4MB/s download speed but the maximum I achieve now is 1MB/s but it's usually 800KB/s. It took over an hour to download a BF3 2GB update for my Xbox 360 the other week. Madness.

Here is all the information requested...

Your downstream power is extremely high, needs to come down some 12dB at least.  You'll need to give VM a call to get them to send an engineer out.

Or you could wait here, leave this thread un-bumped for 3 to 7 days so that a forum tech sees it and gets in touch with you.

You legend! Thanks, I'll give them a call with this information

@ johnafish

Is there really any need to post exactly the same problem 16 times over various threads?

[RampagedDeath]

I have the same problem. It all started around 8PM on Friday. I was getting 1Mps but for the last few days it's settled to around 13mps when I should be getting 50mps. I have an engineer coming round tomorrow because they say my modem power is too high. Hopefully this gets fixed and I finally get a steady 50MB connection that we are paying for.

Hi

I have on a number of occasions put my superhub back on again as I really want to use this item, (I got this when I was part of the superhub pilot), however the last time that I put the superhub back on network I got speeds from 49.69mb (using old modem) to 0.55mb (superhub), a considerable drop in speed, my upload speed wasn't much better.

When I ring customer support the are hopeless and tell me all the time to restart router (which makes me feel dumb as I have a full understanding in computers and IT so I think this maybe one thing I would do first).

They then tell me that the superhub isn't the best piece of kit to use and should go back to the old 50mb modem and router combo, I do this speed is back to a "normal" speed.

When I use the old modem router combo my xbox 360 sometimes has problems even though port forwarding is sorted and DIM is switched on for it.

I also rung the other day (14/01/2012) to upgrade to TIVO and I spoke to them about the upgrade to double speeds in my area this year and asked about getting new equipment as this is what I was told would prob happen, but he said that as I am using the superhub I wouldn't get new equipment (I again explained that I am not using superhub) this guy explained to me that chances are I would have to put this back on to get the 100mb speeds I will be getting eventually and explained that virgin will prob make this item into just a modem and I would still use my router as a router.

could you please tell me what on earth I am meant to do and whether it is worth trying the superhub again and trying to get some sense out of customer support!

Regards

Jonathan

Ok... so... the engineer came out today, and it seems the power levels are massively lower than they were... 

But I am still getting awful speeds, 11.71875 Mb was my last calculated speed following the suggested method.

What else can I do? What am I paying for?

Hi Useoncedestroy,

I have had a look at the network and all is looking good at the moment. Utilisation is looking good and there are no other issues that I can spot that would slow your connection down. The only thing I saw was a drop in SNR (signal to noise ratio) a few days ago, but that has been stable since then.

Are you still seeing slow speeds? I can see that you have wireless connections have you tried with 1 direct connection with the modem set to 'modem only' mode? (this will rule out any wireless issues).
