Buckle up, this one will take a while.
So I moved recently, and as a result, had to switch my ISP to Optimum. I'm WFH at the moment, so I got the nice, super-quick package, and they gave me an all-in-one modem/router. I connected my computer directly via ethernet cable, since, why wouldn't I?
And at first, all is well. But over the next few weeks, I notice a few odd things. First, the only light on the router/modem that appears to be on 90% of the time is the power light. Nothing else lights up.
I pay no heed because the internet's working.
Then, I begin having increasingly consistent DNS issues out of nowhere. There's no apparent rhyme or reason to them, suddenly, I'll just no longer be able to websurf as I usually do. What's extra-weird though, is that if I'm streaming something at the time (a movie, Spotify, even Discord chat), it'll keep going as normal. But otherwise, when these issues appear, generally, both my ethernet and WiFi connections crap out, so I can't access the web on my phone or stream on my PS4, along with my PC being unable to connect to anything.
This has intensified over the last few days, like, really, really badly. I can no longer reasonably count on my web browsers not to pop up a DNS error for six hours in a row anymore. And I've tried almost everything I found in guides onine to fix it.
- I've run several virus/malware scans (ESET NOD32 Antivirus and Malwarebytes)
- I've triple checked to make sure the drivers on my network card are updated
- I flushed the caches on Firefox and Chrome
- I've power cycled the router a sh*tload of times
- I've even flushed the DNS cache
Same problem keeps on cropping up.
Tonight, there was a development. Suddenly, the other lights on the modem (other than the power light) would turn on as my internet would completely drop out. No DNS error this time, I would get the little icon in my taskbar indicating I had no connection to the internet at all. Worse, cycling the power on the router several times didn't fix it. Lights (the internet light especially) would continue flashing, but I had no connectivity. Tried unplugging the ethernet cable, tried everything. Nada.
Eventually, the internet and WiFi lights flashed for a while before going solid. At that point (I checked), I could access the internet via the WiFi on my phone, but my PC was still reporting zero connection.
So I completely powered off my PC and then turned it back on, and, voila, I have an internet connection again. And once again, the only light on the router/modem is the power light.
I'm sure I've left off some parts here, but I'm just trying to figure out if I need to go over to Optimum and yell at them for giving me a sh*tty router (preferable) or, God help me if my network card is sh*tting the bed or my PC has some kind of godawful virus (not preferable).
I've tried just about everything, as I said. And what's extra weird is that this is a recurring issue, but not a constant one. I had days just this past week where I was connecting fine with no issues, but by Friday, things were sliding towards untenable. I've checked the cable connections, I've unplugged and re-plugged just about everything back in. At this point, I'm wondering whether or not the fact that the router/modem is plugged into the wall socket instead of my surge protector is the problem.
Mostly, I'm just hoping this is an issue with an ISP and NOT my computer, but I just need some advice.
EDIT: Also, I'm running Windows 10, if that helps at all.
EDIT v2: Or could it be that I have a LOT of tabs open? Like, between Firefox and Chrome, I have 40+ tabs open, although most of them are usually suspended? Also, PUP.Optional.WinYahoo. has been a recurring appearance in my Malwarebytes scans, although I haven't noticed any changes to my browser as a result. Maybe that?
EDIT v3: Recieved a text from Optimum this morning saying that an outage had been resolved, so perhaps my major issues yesterday were caused by that?
