Keep losing my internet connection in N17

[instigator]

Hi,
I'm having problems with my virgin broadband internet connection, i keep losing it.
It normally happens a few times a day and is starting to get very annoying, it can last anywhere between 5 mins to 60mins.
The cable light on the modem goes out during the outage although the pc and power light stay lit.
I'm on a 20mb package using a Scientific Atlanta 2100 Modem.

Here is a portion of my modem log:

Time Not Established Critical (3) No Ranging Response received - T3 time-out

If anybody has any idea of what is causing this or any advice it would be greatly appreciated.

Thanks in advance.

Your power levels are fine so you need to call Tech Support which is open 24/7 on 151 from your Virgin Media Phone.

It's absolutely free.

Or call 0845 454 1111 from any other phone line.

I had the same trouble instigator for months until it got unbarable over Chrimbo. I got heavy over the phone and suggested I needed a new modem. VM engineer came over found nothing wrong..grrrrrr I hate it when they do that.
I suggested a new modem, he agreed and ever since (touch Ikea synthetic wood) its back to the good 'ol days of 18meg D/L and 712 up...WOW smokin !!!! lol
I hope it is as simple for you.

Good luck

Hmm....
Well i just rang them to find out why the engineer didnt turn up today (booked the appointment yesterday), they dont seem to know what i am talking about, the woman also refused to send out an engineer unless she went through the standard fault finding process which i couldn't do as i was
ringing from work and not at my pc. I dont have a landline and vodafone charge premium rates to ring 0845 numbers so that rules that out.
I understand that they dont want to waste engineers time by sending them
out when they are not needed but i'm not wasting my time and more importantly money because of their own crappy service.

Bye Bye Virgin, time to change ISP! :mad:
