I happened to notice earlier today that my modem was synced at 73,999kb/s rather than its usual 79,997 (it claims headroom to above 83,000 usually, and still is at the moment). I rebooted it to see if it would sync at full speed again, and it didn't — again exactly 73,999.
Has my line somehow had its cap reduced from 80,000? If so, how to I get it back up? (And, just for interest's sake, why might this have happened? The line has been rock solid as far as I'm aware, and still has a bit of headroom both upstream and downstream when sunc at the 80/20 limits).
Modem stats included below (it's a DrayTek 2760) in case of interest / useful for diagnosis!
Thanks for any insights (I'll probably call support tomorrow in any case if it resyncs again at 73,999 when I reboot it at some point during the morning!) …
