I was estimated 3Mb and sync at 6496kbps and that's because Sky have capped me at 6496.. I see my modem reports a max rate of 7138, but I cba ringing to get it uncapped.
Indeed Sky estimated mine to be 5Mb when I joined & I currently sit at 14330kbps. Couldn't be more happier with the service, Always works when I want it to & no slow down at all!
I'd soon take slower speeds, un-throttled & un-managed than a faster service which is throttled/capped/managed to hell.
Sorry Feek I can't answer the question about using your own router. I still use the Sagem personally.
