Get all of the sudden disconnected.
I live in an apartment where I get my Internet from a repeater. That repeater is connected to my pfsense box. From time to time my windows machine (which sits behind the pfsense box via lan) shows up an exclamation mark all of the sudden telling me that there is no internet.
Trying to ping google doesn't work. Pinging my pfsense box is all ok.
Is there a way how to diagnose / monitor the network when such a thing happens?
Send out a traceroute to google or whatever.
E.g. on Windows: tracert google.com
This pings hop by hop, so you will see the most far device you can reach.
This is my tracert from my windows machine to google :
Tracing route to www.google.de [18.104.22.168]
over a maximum of 30 hops:
1 <1 ms <1 ms <1 ms iris.home.hub [10.0.1.1]
2 3 ms 5 ms 2 ms 10.0.0.1
3 28 ms 24 ms 35 ms 22.214.171.124
4 19 ms 25 ms 21 ms 126.96.36.199
5 23 ms 22 ms 22 ms f-ee7-i.F.DE.NET.DTAG.DE [188.8.131.52]
6 23 ms 24 ms 28 ms 184.108.40.206
7 24 ms 24 ms 24 ms 220.127.116.11
8 23 ms 25 ms 22 ms 18.104.22.168
9 33 ms 32 ms 31 ms 22.214.171.124
10 39 ms 37 ms 39 ms 126.96.36.199
11 38 ms 38 ms 39 ms 188.8.131.52
12 43 ms 39 ms 38 ms mrs04s09-in-f3.1e100.net [184.108.40.206]
iris.home.hub is my pfsense box and 10.0.0.1 is the gw to the internet. (Shared dsl connection)

He means run a traceroute when you're having the problem. Your output above is totally normal for a working link.

Repeat this when you have no connection and see where it stops.
Right now the trace route is kind of useless except for reference later on.
Maybe trace the IP so you don't need name resolution which might not work when disconnected.
