Question Modem/Router

[CliffK23]

I've been having issues with suddenlink 1g for a week (packet loss). he came and tested it saying its running good and suggested i get a new router and modem since i have asus cm-32 ac2600 (6 months old). any recommendations on a new setup that is compatible with suddenlinks specs?

The modem should be chosen from the list of approved devices, for your speed package, published by suddenlink. Then any router can be used.
You really need to better identify if you NEED a new router. Have you verified that your packet loss is inside your home ?

It seems to be in my house since he tested their end. ive done ping tests and tracerts test aswell and it seems to be communicating from my pc to router then after that it has issues. IDK what to do as im not very tech savy

If you don't have packet loss to your router, then you may not have a router issue.
What does the power and SNR statistics look like on the downstream channels in the "CM Tuner" page?

 

[CliffK23]

35.595 dB

9.30 dBmV

is my first column and all are pretty close values for the other channels.

You are saying you are getting loss if you run ping to your router ip from your PC.

First I hope you are not testing on wifi because wifi it is very common to lose packets from time to time.

It is very rare to see packet loss between a pc and router on ethernet. There is not a lot here. One of the cheap things to try is a new ethernet cable. Be sure to get cat5e or better if cheaper. The cable needs to be pure copper (no cca) and with wire size 22-24 (no flat or thin cables).

After you are sure the cable is good then the next thing would be some driver issue in your PC. Be sure to disable any so called "gamer" network accelerators that come bundled with some motherboards, ones with killer ethernrt port in particular. Try to find a newer driver on your motherboard site or the chipset vendor. Do not use the defualt microsoft ones if you have other options.

You can also try to boot a USB linux image. You should then be able to ping your router with this OS. This will let you test to see if there is some hardware issue or if it is something in the windows install. The USB image does not install on your machine so it does not hurt your windows install.

There is nothing unusual in that traceroute. Hop 2 not responding is not necessarily a problem.
You would have to do multiple continuous pings to determine a pattern.

What you have shown so far, is not evidence of packet loss, which is your original topic.

 

[CliffK23]

Ok im just trying everything I can think of. What tests should I be doing to verify my router modem combo. And test my Isp

Lets go back to the start. Where do you think you are getting packet loss from. Everything you have posted shows no actual loss.

Is it some game that tells you there is packet loss or something else.

Your problem may be intermittent which is going to make testing much harder.

Yes fortnite keeps constantly showing packet lossfrom 20-35% on upload. My internet download speed usually 700 and is now 600 and upload is .19 which i normally am around 30-40 upload.

I would go back and look at the modem signal levels in particular the upload. You would have to check the actual levels recommended but if the numbers are 50 or above the generally indicates a problem.

Your ISP is making it extremely hard on you when they have configured their router to not respond to ping...ie hop 2.

I would leave a constant ping run to hop 3. This is mostly to collect data for when you talk to the ISP again. You need to show them that you have say a hours worth of ping to your router with zero loss but you see loss to their router in hop 3 with loss. If you only get say 1 or 2 packets loss over a hour that will not cause the issue you see, the number would have to be at least .2-.3% loss have a effect. Normally when you get upload rates that low the loss is huge many times approaching 10%. It should be very obvious.

To avoid the ISP blaming your router I would also test with the pc directly connected to the modem.

I have a combo router modem but I'm going to go get a new router and a separate modem to help troubleshoot and if its not my existing router/modem atleast I can return them.

Just got off the phone with my ISP and he said he can see packet loss from his system and thinks it the coax in my house and wants to send a tech out to come fix that, he didn't give me much info on how he determined that..

The 51dBm power on your upstream is an indication of a problem. You could have a bad splitter or something. Running a brand new RG6 coax from the outside to the router is one way to test it. Just lay the cable on the floor if needed. Your +9dBm downstream signal is good. The power your modem is having to use to broadcast (51dBm) is not good.

I ran a new cord from their coax to a splitter and to my new coax and tested fine. Tried a different coax cable that I really don't want to use but it did fix it. So tells me that the coax I was previously hooked up to is bad. Are these house coax usually split because I found the one in my room and the one on the other side of the wall (I was hooked up to)are connected somehow. Maybe a splitter in the house?

Usually in the attic or basement.

ok and do you know how they would run a new cable if putting new connectors doesnt fix it as it is in the wall? Also if its on a splitter and i tried the other coax would that make it bad as well or could it just be after the splitter to the wall that is bad.
