I have fibre from ADSL24, Coms now I suppose. Up until a few days ago, when using Usenet, I was able to get speeds close to the max my line can get (2.4MBps on a 20-25mbps connection). However, it has now dropped for no apparent reason to around 450kbps. It is not the program as I have tried others and other files too.
Is Coms now shaping traffic? That's the only thing I can think of as I never had any problems of this kind for years when it was ADSL24.
