Thank you for letting me know Eric, it's been some time since I used DSLstats and I seem to recall it was a MSWindows executable back then.
Meanwhile, I ran a VM with MSWindows to test the hg612 modem stats, but the 'Connection Stats' page isn't showing anything yet. I may have to wait for a while - I just set the 'Snapshot Settings' interval to 1 hour.
Regarding DSLstats, could I run this on a headless server, or is it a desktop only application? I don't run a PC with a desktop 24-7.
