Question Frequent and extremely consistent "Request timed out"

[beadtom]

I installed a new Asus Zenwifi AX. When pinging Google I am getting a "Request times out" message exactly every 6th reply (so 5 are good and then time out, repeat). This is happening exactly the same way on multiple computers. When using a voip phone I can hear the person on the other end perfectly but I keep cutting out for them, so seems to be on upload? ISP claims all is good on their end. I cannot figure out what is causing this but I'm hoping the consistency will mean something to someone who can help?

First step is to ping your router IP to see if the problem might be your computer. You want to do this test on ethernet if you are using wifi so your results do not get contaminated.

Next run tracert 8.8.8.8. The goal is only to get the router ip in the path, the tracert by itself means little.

Now run a ping to hop 2. This is the IP of the first ISP router for most people.

Generally if you do not see issue to your router IP but you do see them to hop 2 there is some issue with the line coming to your house. If both hop 1 and hop 2 are good then it is going to be much more complex. You would need to test farther hops but the farther away you get the more likely you are not going to be able to get it fixed, could be in another ISP.

Most asus routers also have the ability to run ping. See if that shows anything interesting. It will eliminate your pc as the source of the issue.

Thanks for detailed reply:

All the computers have the same very consistent timeout issue so it's definitely not a specific PC problem. I do have a switch connected to the router and all the devices are wired so no wifi contamination.

I ran a ping test from the routers web interface and all was good there. But when I pinged the router from cmd it failed all 4 times. Pinging to hop 2 was good.

This is rather strange.

You seldom see ping loss to the router. You technically should see loss to hop 2 also because if the data gets lost between you and the router it can never hit hop 2.

I would test ping to the router from another machine just to see if there is anything different.

It is extremely rare to have a issue to the router and is made even more strange when it is affecting multiple machines. This pretty much eliminates things like ports and cables.

It is also unlikely your switch but since all machine have that in common maybe remove it to test.

After that you start to suspect duplicate IP issues or even worse some strange issue with the router on the LAN side.
