Question been having problems with internet ( packet loss, high latency )

Jul 15, 2020

i have been having internet issue for the better part of a year now and every time my ISP comes out ( suddenlink ) they say everything is working fine which its not. ive noticed that im having an insane amount of uncorrectable errors 72000 to be exact. when playing games such as COD MW, fortnite or rainbow 6, the packet loss is so high it is unplayable. any help would be greatly appreciated.


my current set up is a Netgear C7000v2

Those number are actually very low number of errors. It really depends on how long the modem has been on. It is not real clear how often these reset it seems to be a bit different between models of modem. Even reboot only sometimes clears them. The ISP also clears them from time to time it seems.

I strongly suspect that if you were to check say 5 minutes later you would not see the numbers change or it would be a very tiny change.

You can not really do anything about this. It just means there is some form of interference on that frequency someplace between you and the ISP office. Could be any cable any place in your neighborhood.

This also is not the cause of delays. Delays are caused by data being held in a buffer in some device. Problems with cabling you only see loss.

You need to do more extensive testing. Loss is generally easier to get fixed because it is generally some form of error. Delays are many times caused by over utilization of some connection causing equipment to buffer data.

Pretty standard first steps. Run a tracert to some ip like It likely will not show anything real interesting unless you are very lucky. The goal is to get the IP addresses in the path.

You now run constant ping to the IP trying to find the hop that is the cuase. Problems in hop 1 are generally your router. Hop 2 should be the connection to the ISP. This is where if you actually had lots of unrecoverable packets you would see loss. High ping times on this hop are generally caused by you over using the bandwidth you have purchased. Since most people have over 100mbps cable connections this is not as common.
