No response to ping of specific size

ping <anything> -s 473

does not receive a single reply.

ping <anything> -s 476

works, as well as

ping <anything> -s 472

but no size inbetween. What could be the reasons for this and what can I try to find the cause?

This happens for every request that is between 515 and 517 bytes long (on the wire), no matter what protocol. Wireshark shows lots of "TCP retransmission" for HTTP requests of this size. – user338666 – 2014-06-25T18:33:21.343

I search my gateway with route, and after I ping it with no problem ping 192.168.1.1 -s 473. I repeat with 472,476,515,517.. all ok. I repeat with a fixed IP on internet. No problem again. Which is your system, which the version of ping? – Hastur – 2014-06-25T18:50:46.600

1@Hastur I tried this and it turns out my UMTS USB stick is the culprit. – user338666 – 2014-06-25T18:54:47.720

1Write it as an answer, add the model of the USB stick the version of your system and of your ping command. It should help somebody else, and welcome on superuser. – Hastur – 2014-06-25T19:04:02.997
