So, I was going to call #homenet to complain about my shitty connexion ever since their maintenance a couple of days ago.
Checking speedtest on my wife's PC though, showed she was getting proper speeds...
Then I noticed an orange blinking light on the router's LAN port my laptop is using... Unplugged it and plugged it back in, and yes, speeds are back to normal... I guess the cable might've been pulled out slightly (I ought to crimp a new plug on one of these days...), and been working on half-duplex mode instead?

Wish I'd checked that sooner... at least I hadn't called them yet....

This is far better than the 40Mbps I was getting before...
