Slower internet 21 June (from average 107Mbps to 70Mbps)
In the month of June there were several internet interruptions, longest 1 hour and 22 min on Wednesday 12/6. I have daily small speedtest running, which started reporting remarkable slower speed since 21/6 of that month.
I've a NET Wahoo subscription which gives 125Mbps, previously speeds average at 100-110Mbps, this dropped to 67-72Mbps afterwards. This trend continued in the month of July and now month of August.
What could be the cause of this?

Connect a pc in dhcp mode directly to the modem without your router and take a speed test in this configuration.

What kind of speed test are you running ?
Instead, I advise you to provide us with one or more cable speed tests performed on our reference site:

You can use the link at the bottom to share the results or use screenshots
Thank you in advance.

that one I just ran manually and it shows me 70Mbps download, whereas previously in early June it was at 100-110Mbps mark, a noticeable drop.

restart of cable modem has no measurable impact

Can you post your modem signal levels ?

Many thanks for your feedback.
Check your personal router , if some QOS rules are not enabled by error.

you're gonna enjoy this.
so I was using a Netgear wndr3700 v4 with DD-WRT for internal router purposes.
with the full speed at the cable modem, I went into research mode for the netgear WNDR3700 with DD-WRT. When you flash DD-WRT custom router firmware it doesn't use any hardware acceleration anymore, so everything is done on the CPU. I suspected and found reports of people having similar issues with reaching 100Mbps+ with native firmware, but lower with DD-WRT.
so I bought a new high end R7800 Netgear router, this would fix it, 1600Mhz CPU and quite recent.
installed it. plugged everything in.
internet ok on desktop PC which is not directly plugged into this router either, let's run that speedtest again: 39Mbps
what?
take test laptop to Netgear router: 125Mbps.
Ok so maybe cable between router and office where there's a gigabit switch, Linksys SD2008.
start following cables, touch the switch, burn hand. Ouch
hmmm.... swap out that Switch for another (cheaper) off-brand Gigabit switch, speed back up to 127Mbps from desktop PC
so root cause of slowing internet connectivity from PCs in the office: a slowly dying and overheating Gigabit switch ( https://www.legitreviews.com/is-your-linksys-sd2008-switch-overheating-or-losing-connectivity_785 )
an interesting few days to say the least
