I've been having this issue for a few days now. Roughly twice a day, for 10-15 mins, my internet just suddenly goes out without any warning. Then it comes back and is totally fine again. ISP says that there's nothing going on on their end (and most of the time when I have an internet outage they do say they're having an issue)
Is the router just fucked? Are there web goblins stealing my interwebs? Is there any way to tell?
Probably a setting on your router that is bugged?
Or maybe the router is updating/restarting automatically daily.
