Add airflow to your router, common issue for overheating routers. May need to move it out into open, out of a closet or whatever.
If your ISP hasnt sent you a letter yet then try something much more tracked like GoT and if you dont get one after a week then you should be fine.
Pretty sure it’s programmed to reset at night from the ISP themselves, so not much luck there.
Also I have in the past for emails, but that was before I got my VPN subscription. Nothing since then, but I ain’t chancing it.
I never use router from ISP, I use my own. Most routers from ISP are awful.
I don’t have a choice as there is almost no way I could convince my parents that using a 3rd party router would be the way to go. Especially trying to convince my dad, who once got pissed off because I wanted the password for the old family computer to remove a browser extension that was probably malicious.
I’d set up a 3rd party router by snaking an Ethernet cable to my room, but I’m not confident enough to change and keep up on router settings to keep me safer. Let alone updating the router if I go the route of a 3rd party nos, which I’d probably try.
