Problems with 100Mb speeds varying a lot.

I've been having problems with my speed for over a year now and never got any joy by calling 150. I could never get past the person insisting I connect my PC directly to my modem, and bypassing my firewall. I understand the reason they ask this, but they always refused to go any further when I told them I had good speed the previous day.

 

Anyway, I've lived with it for a while now until recently when I kept getting dropouts. So, I checked my power levels and they were quite high. I then changed my attenuator from 6dB to 10dB and it worked perfectly, no more dropouts and I was getting speedtests of around 80mbps. I was getting transfer speeds in excess of 9MB/s. Fantastic I thought to myself. That is until a couple of days ago, when the speeds went back down to 600-700KB/s. I've tried changing the attenuator back to get decent power levels again, but the problem looks to be one of the channels the modem has locked on to is way too high.

What frustrates me more than anything else is that I keep getting these problems. It seems whenever anyone in my area gets a problem the box in the street gets "messed" with and my service goes to **bleep**! The box in the street is about 20 metres from my house, so I've always had problems with too much signal. It just seems like an obvious thing to do to me to check if everyone else in the area is still okay. Or at least have some way of notifying people that some work has been carried out and to monitor the quality of service. Anyway, RANT OVER!

 

Can anyone suggest how I can get this fixed. I don't fancy my chances of get past the script readers on the 150 number. Is there a way I can just get an engineer booked in to come and sort it out?

Re: Problems with 100Mb speeds varying a lot.

150 option 5 and then 2 (Thinking of leaving us) and then ask for 2nd line tech support.

 

The Last Downstream powerlevel looks to be one of the ghost ones thats a bug in some superhubs.

No More like people don't want to quit with VM in the weekend as the options I said are for the disconnection line or rather the retentions team.

Re: Problems with 100Mb speeds varying a lot.

I've just rebooted the modem and got rid of the high power on channel 135.

But my speed is still pathetic. I am beginning to think I have a faulty installation or modem.

Download speeds are worse than I had 10 years ago!

Hi antony,

 

The UBR which handles your connection is currently suffering from packet loss which would be the cause of your slow/intermittent connection.  This has been raised to our network teams under reference F002077081. Work to resolve this issue is currently scheduled to take place on 16/07/2012 (although this may be subject to change).

We're very sorry for the inconvenience this has caused.

Kind Regards,

Re: Problems with 100Mb speeds varying a lot.

Is that still an on-going problem. I still have the "ghost" channel. I've had awful speeds for over a year now, but have never got past the script readers telling me to reboot my modem or connect it directly to my PC. I'd really like to get a reliable connection *and* fast connection.
