slow internet speed and no access often between 7pm to 9pm
I have a reoccurring problem, slow internet speed and no interne access often between 7pm to 9pm.
This also happens at a few other times at random, but almost daily at night.
Does happen with devices connected over Wi-Fi and devices connected by LAN cable.
I did take a look from this end and the modem appears to be online and not reporting any significant issues. Can you try connecting a PC directly to the modem then pushing the modem's reset button and see if that works any better?
I'd also recommend, if you have a separate router, to reset the router to factory defaults and set it back up as well. If it is normally a specific set of times it could be settings corruption. (@ChrisL recommended doing it to the modem as well)
