Spotty Internet Connection, again...

Hello,

I have already started a topic that was solved about my internet connection being very spotty and dropping out completely at times. Well we figured out what the issue was, (the cables were bad, literally cut halfway through after we hired people to put up a new front porch at our house) and I contacted Spectrum with my issue, they sent out a tech, and the problem was solved. But months later, it's happening again, and sometimes the internet will go out after viewing any random website/app, and other times it will just happen randomly when we're not using it. I am a huge online gamer, I play on Xb1, PS4, PC, and Switch, and i've experienced slowdown and complete internet cutouts while playing. I was playing Fortnite with some friends the other day, and my game started lagging very bad, to the point where I couldn't play anymore. And I think the 100/10 plan should be fine for gaming and pretty much anything else. We even get more speed than that when our internet is actually working at it's full potential (120/12) Just earlier today, I was viewing a website on my iPad, when the internet connection also just went out completely. The only way I can get it to work again is by powercycling and renewing. Whenever it goes out, just to make sure it's not that individual device, I can go on my modem's website and it'll say: "Cable Connection: Not Working" or "Attempting to Reconnect" I can post modem signal levels if you want me too. And it's definitely not the modem/router, it used to do the same thing on our older ones too, and we replace our modem/router every once in a while. Even when the internet is actually working, I experience lag on games and slow downloads when downloading files, and while streaming. Our internet and router should be well able enough to handle multiple devices, but it even happens when I have just one or two connected! When the internet is working at it's full potential, it's great, don't get me wrong, but it just slows down and shutsdown way too much lately. Other members in my household are also experiencing slowness on the internet at times. I think there may be something wrong with our area too, because I know a lot of people in my area that are also experiencing major issues with Spectrum. I would also like to add that not only are our wireless devices experiencing this, but everything that I use (PC, PS4, XB1, Switch) are all wired directly to the router, and experiencing lag. So does anyone have a solution/suggestion that I could use?  I consider myself pretty tech-savvy, i build computers, so I will probably understand technical terms.

Thanks,

Josh

Re: Spotty Internet Connection, again...

don't reset, post sig and error log pages...

What speed do you pay for?

 May have too many devices on

Re: Spotty Internet Connection, again...

We pay for the 100/10 plan and have a Netgear C6300 modem/router combo which is very capable of handling multiple devices at once. And when i'm gaming, i'm only using one device at a time. The error logs are too long to include in one post, but I do notice a lot of DoS Attacks listed like: [DoS attack] AIFSmiley Very Happyropped INPUT packet: PROTO:TCP SPT:62514 DPT:5555, and [DoS attack] ICMP Flood from 104.49.107.0.

Re: Spotty Internet Connection, again...

low correctable counts are ok, provided modem has been up for a few hours or more, bad if that's only a couple minutes.

 

See if you have WMV streaming media enabled in the router?

Re: Spotty Internet Connection, again...

It's on, it was on by default when we got the modem router, but we don't stream local media through our router

Re: Spotty Internet Connection, again...

Are the DoS Attacks something I should worry about? Is someone really trying to hack our network? Or is this just a glitch causing some event to show up as one?

turn it off.... see if that helps... some gaming is interpretted as media streams.

Verify somethings not hoarding bandwidth, like Cloud, dropbox, sync, onedrive, etc.

Re: Spotty Internet Connection, again...

Okay thank you, I will turn it off. Should I email the abuse email about the DoS Attacks? I looked up some of the other IP Adresses, and some were from Korea, China, and one was from the San Diego Supercomputer Center... strange. Can people use other IP Adresses to disguise themselves?

Thanks again.

I also just noticed a lot of errors in the event log too, here they are:

Anything to worry about? Are some of these errors a cause of the DoS attacks? Or should I notify Spectrum?
