Internet connection problems.

[oneano]

Comcast tell me that my modem is wel behaved and healthy. So I guess that it is my router... I have purchased probably 6 routers in the last 10 years why can I not find a router that works?
I have a random generic router Linksys e2500 I have several devices connected, One laptop, two desktops, two ipads, two phones ... rarely are all of those devices being used at the same time.
Average ping time is around 30 seconds it will jump up to around 100 sometimes and I get frequent timeouts.

Is there a solution to fix this? I would love to know.

I see you are trying to ping to an outside host. You can try 2 things.

1: Try pinging the gateway. Just make sure it's not a internal network issue.
2: Try doing a tracert to an outside host. This way you can see where the ping drops in response time.

From a dos prompt run "ipconfig /all" and get your gateway IP. Ping that gateway IP address via ping nnn.nnn.nnn.nnn from the command prompt. That will tell you if the latency is your internal network or not. You could also ping another computer on the network as well if you get its IP using ipconfig.

Those ping times you show are milliseconds not seconds and are actually pretty good for external pings. The frequent timeouts could be an issue.

For testing external sources you need to know how far the server is away from you that you are pinging. You would want to ping one in the same city or very close.

Just for example if you go from Texas to New York traveling at the speed of light it takes the light about 10ms and that is just theory in reality there are many switches / routes that occur over non fiber networks so the farther you go the higher your ping.

For the Linux environment the command is ifconfig. Just to be sure.

I have been checking ping times and tracerts over the last few weeks trying to catch my internet when it is down.

this really seems to be an intermittent problem with some days being worse than others.


Today I have noticed common sites like Facebook are incredibly slow. When I run a tracert on Facebook I get destination net untraceable


when I ping something like gmail, I get the same "destination net untraceable '

but, I am watching videos and using gmail even when I get these errors.

Is their a way to test ipv6 vs ipv4 traffic? When I ping gmail for example it is pinging an ipv6 address
