I'm with orcon and just noticed much lower speeds recently checked my NF4V and my attainable rate has gone down for Downstream for sure, and probably Upstream too.
Previously had 25Mbps downstream, now have 8Mbps downstream, only recent change is modem got moved to a different wall socket recently, also noticed the VDSL profile changed from 8b to 17a, which as far as I can tell should be a good thing right? Have a screenshot of my old xDSL stats from a post I made a few months back and a screenshot of current xDSL Stats. Is this a potential issue I should ring the tech people about, or is it more likely to be due to moving the modem. It doesn't make sense that the profile would go up but speeds would go down? Last time I restarted the profile was initially 8b again but after checking now its back to 17a.
According to the national broadband map my area has 15-60 Mbps available. So being at 8 seems like somethings wrong. Attenuation is about the same as in my old screenshot so I don't expect the changed port has any worse noise or anything which is what I thought may be the cause.
Any wisdom would be greatly appreciated.
