I have a very bad internet connection, so I had a 4G/LTE modem to access the internet. Behind it is an asus router to which all my devices are connected. But this was a bit slow recently, so I upgraded to a 5G router, Huawei 5G CPE Pro 2, at a different provider (Telekom in Germany). Then I noticed some connection issues here and there and started investigating, though my networking knowledge is very basic.
Now I noticed something weird to me. If I use traceroute to see the route to some site using the 4G modem, traceroute shows me 15 hops to the target.
traceroute to example.com (93.184.216.34), 30 hops max, 60 byte packets
1 router.asus.com (192.168.2.1) 0.146 ms 0.179 ms 0.172 ms
2 192.168.1.250 (192.168.1.250) 0.646 ms 0.799 ms 0.884 ms
3 192.168.225.1 (192.168.225.1) 3.115 ms 3.578 ms 4.800 ms
. (Multiple detailed hops) .
15 93.184.216.34 (93.184.216.34) 143.814 ms 148.034 ms 146.367 ms
But if I do this with the 5G modem, I get the first two hops from here to the modem, and then only stars.
traceroute to example.com (93.184.216.34), 30 hops max, 60 byte packets
1 router.asus.com (192.168.2.1) 0.127 ms 0.160 ms 0.154 ms
2 192.168.8.1 (192.168.8.1) 0.613 ms 0.608 ms 0.652 ms

... only stars
30 * * *
What could that be? Is there some networking or IP shenanigans that the provider uses? Changing the DNS entry does not change it.
Thanks.
