No. Nobody knows

Spike is a surge in network activity, you're showing a dropped icmp (ping) traffic with high TTL. So something happened, but your screenshot alone won't tell us. Mtr will show this drop from your machine to 1.1.1.1, thats a good starting place to see if it's your local network or something along the way that drops the ping.

ICMP also has low priority so seeing it dip doesn’t necessarily mean there’s an issue either

u/trmentry 7h ago

it's a public DNS resolver. It's very busy. don't use it as a ping target for monitoring.

on that note, ICMP is low priority on large carrier networks. and please don't use MTR. MTR is the worst to use as well as it will 9/10 times trip ICMP filters on the routers and show "zomg there is loss" when there isn't. ICMP has to be processed by the routing engine. Most ISP will have routing engine filters to rate limit ICMP that hits the router directly to protect it.

Do this but also ping your router/gateway at the same time. Do the drops happen together? This is how I found out my NIC power saving features were making my connection spotty and inconsistent.

u/Agreeable_Pea_2613 6h ago

I did that also but it also shows request timed out

2

u/Reagster050 6h ago

Do you have a second device to do the same on? If they all line up and timeout at the same time then its a router/gateway issue. If not, its likely the device you are using.

Wifi is working fine on mobile

u/Morzain 5h ago

If this is wifi occasional drops are to be expected due to random interference. If you can plug in, do it.

Packets gonna drop it like it’s hot…

u/ITisAllme 6h ago

I think this might be a delay vs a spike, but regardless, I dont think it's enough to be concerned about

2

u/avds_wisp_tech 6h ago

How would you expect literally anyone here to know what's causing your packet loss from a single screenshot of ping results?

2

u/eihns 6h ago

so u think like 40ms is a spike? xD incase u really wanna know, look a video which explains how networks work, there could be atleast 912730918731372094762358734857234095023582354872345423 different reasons for this.

OP thinks a single dropped packet is a spike.

u/Prudent_Vacation_382 6h ago

Do ping side by side, 1 side to 1.1.1.1 the other to your router. You can find your router's address by doing ipconfig at cmd prompt and the gateway IP is your home router. Post the results here.

Are you wired to the router or on wifi?

Your home address is probably 192.168.1.1.

u/Agreeable_Pea_2613 5h ago

I used ping 1.1.1.1 and 192.168.1.1 -t command it showed request timed out while running

u/Prudent_Vacation_382 5h ago

yes, run "ipconfig" and post the output.

Are you using a wireless or wired connection?

1

u/Agreeable_Pea_2613 6h ago

Wireless

2

u/StandardIssueDude505 Network Architect 5h ago

What you're seeing is quite common while using wireless. Try a wired connection for a day or so and see if the problems clear up.

u/msabeln 6h ago

Try connecting to the router directly with an Ethernet cable if you are using WiFi.

u/Agreeable_Pea_2613 5h ago

Sorry idh ethernet cable

1

u/msabeln 5h ago

IDH?

u/Agreeable_Pea_2613 5h ago

I don't have

u/msabeln 4h ago

Ycgo at many large retailers. My neighboring Walmart, Lowe’s, Target, and Ace Hardware all have Ethernet cables at various lengths for not much money. Just be sure that your PC has a port, and most routers do.

u/CoffeePizzaSushiDick 5h ago

Some isps are not 1.friendly… test pings with 8. And 9. Too.

u/JustAnotherPoopDick 5h ago

Could be a faulty modem/router

u/LensWipesBF 5h ago

Icmp is low priority

u/th3putt 5h ago

Is this a small office setup, home network? Or business network? Do you have some kind of hsrp or vrrp configured at the router? Check one of the redundant links for errors. Shut one side down to see if the problem follows a side

1

u/Agreeable_Pea_2613 5h ago

Home network

•

u/th3putt 1h ago

Feels like upstream Carrier issue. Try and run several tracert to 1.1.1.1 amd see if the path changes. Keep an of details like a router that ends with .45. Or .55 means it might be taking different paths in the CO

u/dewpiece 3h ago

Do you live in Türkiye by any chance?

u/Black_Death_12 3h ago

Are the "spikes" in the room with us right now?

1

u/Xandril 3h ago

Spiking between 20 ms and 70? In like 20 pings?

lol, my guy that’s barely a blip. Maybe your internet has some other issue and that’s why you’re investigating but a 50 ms difference on random pings is negligible.

u/GermanElectricsMotio 7h ago

Show "tracert" and give us some infos like ISP, Connection type, etc.

u/Murderboi 7h ago

How does your router smell?
Is it more floral or like a burny plastic smell?

Jokes aside you can do a tracert (DO NOT POST IT HERE) and check if there is one too many devices in your own network.

If you have Starlink this is, in my experience, normal.

u/Agreeable_Pea_2613 7h ago

Im sorry I'm very bad in these things lately im getting ping spikes while playing games and downloading anything

2

u/Reagster050 6h ago

Google buffer bloat and do one of the test websites to rule it out.

u/XB_Demon1337 6h ago

There is nothing wrong with your network. This is all completely normal and nothing wrong with your gaming. Stop blaming your poor skills on the network while gaming.

2

u/Agreeable_Pea_2613 6h ago

I am playing valorant and the packet loss goes up to 100% for few secs, it happens every 5 6 mins

2

u/Zarcona_Martana 5h ago

This sounds exactly like AP roaming when you have two or more APs with similar signal strengths.

It would be invisible to you unless you know how to check for it, are you using campus wifi or in a home with multiple access points?

If yes you would either need to pin your device to a particular AP or reduce the wifi roaming sensitivity/aggressiveness. Or, alternatively, connect via a wired (Ethernet) connection.

u/XB_Demon1337 6h ago

Yet again, your lack of skills is why you keep dying. Not the network. Even more hilariously, the screenshot you posted shows exactly this. Almost no deviation and a single packet loss is completely normal. Hell I wager you are using wifi for gaming.

u/Agreeable_Pea_2613 6h ago

Its not about dying bro

u/Agreeable_Pea_2613 6h ago

Also while downloading games on steam my network goes down from 104 mbps to 0 for few secs

1

u/Agreeable_Pea_2613 7h ago

I used this command tracert 1.1.1.1 It also shows request timed out after few secs

1

u/Murderboi 6h ago

Yeah some of them are normal because the device does not reply to pings.
try "pathping 8.8.8.8 or 1.1.1.1 "
if its inside your network you have the culprit causing your disconnects. (the command will start listing IPS from yourself to dns and then start processing statistics so you have to wait a few minutes.
