Question Tons of packet loss coming from modem

[Suidd]

Ive been lagging a lot and having tons of packet burst lately. I used ping plotter and I have a ton of packet loss from my modem. what does that mean exactly do I need a new modem or is this a ISP problem?

It means you are reading the results of the tool incorrectly.

You are showing 50% packet loss to your modem/router but no loss at all to the final node.

If rather than routers these were traffic light on your way to work and 50% of the cars fell in a big hole and were destroyed. Yet the results also say 100% of the cars can get to work on time. Both can't be true.

This is many ways is why tools like this should require some training to be allowed to use. Too many people go "RED BAD MUST FIX".

A issue in the trace would start in some hop and then appear in every hop past that point.

This does not mean you do not have a problem it just means it did not happen when you ran the tool. You are many times better off using constant ping command to the various hops in the trace. Doing it that way also helps you understand more how the testing is done.

Update your post to include make and model information for modem and router. (Or modem/router if combined.)

How are they all connected? Something like the following line diagram?

ISP === (coax, DSL, fiber) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices

With other Router LAN ports -----> Wired network devices.

(Feel free to edit and correct my line diagram as necessary.)

Also run "ipconfig /all" (without quotes) via the Command Prompt. Post the results.

You should be able to copy and paste the results without needing to retype it all.

I have a Altice UBC1326AA00 44378 Wireless Modem and my connection is ISP === (coax) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices

my main issue is that I lag around 7PM everyday and its really annoying to deal with everyday.

I just always have insane amounts of lag and packet loss around 7pm and it usually doesnt fix until 2 or 3 hours later.

How physically close are you to your neighbors?

Not sure about that 7 p.m. lag time.

However, "ipconfig /all" shows that the DHCP IP lease time is only one hour.

How many devices on your network? Are most in use/online during the post 7 pm hours?

I would change the lease time to a minimum of one day/24 hours. Longer time if supported.

Who has full admin rights to the router? That person will need to make the lease time changes.

Another thing to do would be to change the DNS Server settings on the Desktop to Google using 8.8.8.8 and 8.8.4.4

what does that mean DCHP IP lease time is only one hour?
and only about 2-3 its just my girlfriend and I that live here.
and my ISP is the one in control of my modem should I just buy one?

no one lives near me last two unit are empty

Is it possible to hardware this system to the router?
Instead of WiFi.

A Cat5e ethernet cable, of whatever length is needed.

yeah im using a ethernet cable im thinking its either my ISP or the cheap modem they gave me

If your network is (per your post):

ISP === (coax) ===> Modem ---->[WAN Port] Router [LAN Port] ----> [LAN Port] Office Wifi Access Point ~~~~> Wireless network devices

The Altice modem appears to be a modem/router with two LAN ports.

What make and model router? Who has full admin rights to that router? Could be that if the router was left at its' default settings then the network is open and unsecured. Router IP address being 192.168.1.1 which is commonly used.

What device (make and model) is that Office Wifi Access Point? How and who (if anyone) configured the Access Point?

Normal configuration would be that the modem's router functions would be disabled and those functions left to the Router connected to the Modem.

The router thus handling all network related functions regarding IP addressing and lease times. Along with wireless access to the network.

And the Access Point would have a static IP address via the router and secured against other access.

Lease time being important because every network device will need to request that it receive an IP address every hour. Versus more conventional lease times being a week or more as determined/required by the network/router adminstrator.

Immediate objective being to discover and understand the current network configuration: physical connections and router configuration settings.

Most of which is in your control - not the ISP.

My overall sense is that the lags etc. are likely some configuration error of omission or commission.

Run "ipconfig /all" again and post the results.

Also run "arp -a" and post the results.

You could try your ping plotter during the time you say you see issues maybe you get lucky and the tool will show somethings.

Otherwise try a normal ping command. Open 3 cmd widows.

In the first type
ping 192.168.1.1 -t

The second try
ping 10.4.6.93 -t
.....if that doesn't respond at all try 173.219.243.132

In the third use
ping 8.8.8.8 -t

You generally will never see issues in hop1 this represents equipment in your house.

The test to hop 2 is the most common and most easily fixed by the ISP. It represent some issue between your house and the ISP.

The third one is just a google DNS server that tends to always respond well. This will represent the total path and all it does is confirm that you are actually have a real issue when you think you are having problems.

I ran all 3 and ive been lagging for about 3-4 hours and its never a stable connection.

It could be better than this but it is generally not bad enough to cause you any issues. There is no actual packet loss and the latency spikes are only about a extra 50ms or so and they are just here and there. What application does it cause problems in. Even most games are not affect by the small variations you are seeing.

When you tend to see problems in games is when you get a lot of packet loss or you get a bunch of large...like a extra 200-300ms in a row.


It does appear to be on the connection between the ISP and you. Your big problem is although the ISP might partially guarantee some "up to" bandwidth number you will see no mention of latency. If you saw packet loss that they would likely fix because it is due to some defective equipment.

Latency is caused by data being held in buffers because some connection is over utilized and rather than discard the data they hold data for a short time and hope there room for the data later.

The most common place would be to overload the bandwidth you buy from the ISP. It is not as common now that people have huge internet connections. Check that nothing in your house is doing large downloads or in some cases uploads since the upload bandwidth tends to be lower and easier to exceed.

The next and almost unfixable issue is if the share cables that come to your house and your neighbors are over utilized. This means the ISP sold internet service to too many people. The ISP can only fix that by running more wires under the street.

You can call them and discuss this maybe they know of some issue that they are planning to fix.
