I've been having this problem for pretty much weeks at this point with no end in sight. As frustrating it is in itself, it's even more enfuriating because the thing seems to do this whenever it pleases.
To make the long story short without leaving out important details before I go on a research paper long rant: My internet keeps dropping out at random times for only 1-3 minutes at a time. It's always back very soon, but then it goes down again, sometimes hours later, sometimes IMMIDIATELY after. It is completely random, the last person I spoke to suggested this is because of my internet speed (my speed is fine for what I do, I have no complains about it, and I do quite a few speed-reliant things) and that I use too many things at the same time, and that I should minimize the amount of things using WiFi/Ethernet at the same time, yet it went down 4 times in 50 minutes the other night when I was trying to watch a YouTube video on my phone, and worked for hours on end while I played a really fast paced video game connecting from the West coast of the US to a European server.
There was a precedent to this, it used to go down much less frequently but it did so for longer periods of time. I called Time Warner, we arranged to have a tech come out, but eventually I got a call from them saying it was fixed, so we cancelled the appointment. And it WAS fixed. It worked for about a week or so, then it started doing what it's doing now. I made a call, they said they made some changes to the settings and that it should work now, but that was not the case. I called most recently yesterday, they said they changed some things again and they'll monitor it and I should give it until Tuesday (3 days from now) while they monitor it, if nothing happens they'll send a tech out. It's still doing the same thing and it shows no signs of stopping, and I am DEFINITELY not willing to let this mess up my 4 day weekend if I can help it.
Some notes: I have tried switching channels multiple times, 1, 6 and 11 all have it happening. As silly as it sounds I have tried to rotate, flip, etc the modem/router box (it's the one Time Warner gives out, an Arris, not sure of the model but probably the newest one since this was installed about a month ago), didn't help, neither did resetting it. I use the 2.4g connection and don't really touch the 5G, but they both go down simultaneously. The 2.4g blinks sometimes but the connection works anyway, but when it goes down, all the lights stay on for a while, then the 2.4g and 5G lights go out, while the Online light starts blinking, until it all goes back to them constanlty being on again and the internet coming back on. I do NOT have any TV and there's nothing that should be interfering. I only use my laptop, desktop and phone, at least as of late.
Any help would be greatly appreciated, if you need me to provide event logs or something similar, tell me and I will do so.
