In the past month I've changed my ISP from Telecom to Flip. On the Telecom plan we were averaging about 4mbps download speed I think but since switching to Flip we've been unable to get past 1mbps. This makes quite a difference if we are trying to stream decent quality video, especially in the event that more than one of us in the flat is using the connection simultaneously.
I've called up Flip on several occasions and tried all their suggestions but with no improvement. They also have apparently had a technician check our line at the exchange (not sure what they did exactly but we were adamant that we didn't want to incur a callout fee at this stage - any ideas what the technician would have done?).
I've tried three different modems, with the one we are using now being a Linksys WAG200G. I've run an isolation test on two different jackpoints with no difference to the connection speed. One weird thing I've noticed is that when I connect the modem directly to the jackpoint without using a filter, the downstream attenuation is considerably lower (20dB vs 68dB) and the sync speed much higher than when it is run through a filter, however unfortunately we are unable to browse/download at all unless we plug in the filter and run the modem through that.
Here are the connection stats firstly with a filter
and without a filter
There's quite a difference there as you can see. We are due to pay our next month's charge in about a week's time but I feel we're not getting much value from our current ISP with a connection speed of only 1mbps. Due to it being a flatting situation, we're not keen to go back to a contract as none of us are sure how long we'll be around. In saying that, the Telecom connection at least seemed to be at a reasonable speed. By the way we are at the top end of Jervois Road in Ponsonby so although the wiring in the building possibly isn't the best, it's unlikely that we are far from a cabinet/exchange. The Chorus map shows that we should be able to get either > 10mbps or > 20 mbps downloads where we are.
Anyone able to hazard a guess as to what's causing the slow speeds? Happy to provide additional information if it'll help.
