Done all speedtester tests over the last three days, until I was sick of doing them.
IP profile was around 250K most times, even down to 75K, which is bad for a line that has provided, usually 2Mbs or so for over the last 5 years or so.. Had meaningful talks with my ISP, at least twice a day giving them the speedtester results and routerstats. At least the call center wasn't off shore and all parties used mother tongue english
Interestingly, speedtester shows the IP profile to be back to around 2500, which I would consider normal for my line on ADSL max...
Download speed achieved during the test was - 2279 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Your DSL Connection Rate :3072 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 2500 Kbps
Hopefully this situation is now resolved. Also need to check my neighbour to see if they have returned to normal throughput as well.
Roll on FTTC, due end of month (maybe)
