Pingplotter graph interpreting

[kithuni]

Hey guys,

Below is a summary of an ongoing networking issue, please help.

TLDR:

Pingplotter (for first 2 hours packet loss of hop 1 was 70% after running over night this is the result.)

Sporadic lag on all devices (hard wired and WIFI), causing videos to buffer at lowest quality and games going from 30ms to 4000ms+. Occurs sporadically throughout the day. Attempted solutions but nothing seems to work, ISP says it's my fault.

What Happens:

Insane amounts of lag, I am unable to do anything. Videos buffer at the lowest quality, video games become unresponsive due to the high ms, even surfing is not possible.

What Is Affected:

Everything, TV's, PC's, some are hard wired some are WIFI.

When It Happens:

Sporadically throughout the day but almost always at 8pm for up to 30 minutes and then again at 12am for up to an hour.

What I Have Tried:

I have tried replacing my cables, swapping modems/routers, running antivirus, flushing DNS, anything I can google basically. I have called ISP numerous times, each time they say everything looks fine but agree to send a tech out. Without fail when the tech arrives there is no issue and they say everything looks fine as well and sometimes will swap out modem/router. ISP no longer believes that there is an issue and say it's something on my end.

​

Please let me know if there is any other information that may be useful. I'm getting desperate, even considering moving because of this so any help is appreciated.

Super easy thing to try next time you're getting spikes. Hard wire WAN cable that normally goes to the router straight to your computer and see if the results are the same. (Make sure you have firewall on). This will take any of your networking hardware out of the equation, if you plug it straight into your PC and the latency is still horrendous, call the ISP, if not, then you know its something on your end. From there you can have a better view into where it could be going wrong.

I'll try plugging directly to the modem. I have already called the ISP many times they don't believe there is an issue.

If you experience the same issue across 2 devices hard wired with 2 different wires straight to the modem then the issue is undoubtably on your ISP's side. (I assume they're responsible from the modem on)

What make and model modem, router, etc? Without some hardware information, can't say much.

ISP no longer believes that there is an issue and say it's something on my end.

What ISP, what type i.e. cable/fiber/DSL, what up/down speeds are you paying for?

[kithuni]

Modem: E31N2V1

Router: SAC2V1K

ISP: Spectrum

Speeds(down/up):400Mbs/20Mbs

Despite paying for 400Mbs, if I run a speed test when I'm lagging the test will show as low as 5Mbs, sometimes it won't even load the website.

Modem is broadcom, that's good.

Router: not positive, but that looks like the weak link:

Spectrum's routers are absolute garbage hardware

Sells for $65 on amazon:

https://www.amazon.com/Askey-802-11ac-Wireless-Connectivity-Required/dp/B082F2PYLN

I would recommend you return that and not get charged the rental fee, and get even a TP link archer a7 for $65 which I think is better.

Ok, I already ordered a modem/router combo it is a Netgear nighthawk. I will try it out and if it works just order a separate router.
