I am engaged in some network troubleshooting and I am trying to understand the results of a pathping test. What the results show is many dropped packets and high latency up to 10 seconds between the my internet gateway and the first hop on my WISP. It sometimes shows lots of latency at the first hop too. Never any latency at the gateway.

So what is causing this? Is it a problem at the gateway? A problem at the first hop? Or is there some type of wireless interference between the two?

Unless you have actual control of the modem/radio device there is not a lot you can do anyway. Generally the way these systems are put together you have your router---some kind of radio on your house----the tower-----more radios to other location----ISP router that has a IP. It could I suppose be the cable between your router and the first radio but it is highly unlikely. It depends on the system but many the ISP have a way to get into all the radios so they can see the actual errors if they are occurring.

It depends what kind of system they are using. The really stupid ones are just 802.11 wireless and delays and loss are caused by devices stomping on top of each other. Some of the more advanced proprietary systems the central radio will control when the client radios can send. When they are running at heavy load condition you can see delays but it will still pass much more data than the ones that make no attempt to control the client radios. Also many of these WISP systems have many wireless hops between locations you can not see with a traceroute tool since they appear as switches.

@Bill001g

Thanks for the reply. What I am trying to figure out is whether the problem is on my end, their end, or if there is some third party interference. The pathping shows no congestion/packet loss at the gateway itself but rather in-between the gateway and the first hop. However, I've since read on the internet (FWIW) that congestion on the node can show up as corruption between hops.

I want to go to my WISP with the pathping results and complain but I don't want to look like an idiot in doing so. I know technical support and their first instinct is always to blame the user.
