Hmm, there's a problem with your procedure. 

In order to specify the size of a ping package, you have to use "-s" and not the "-l" parameter.

-l 65500 would mean that you "shotgun" all those packages and ping's manpage
(https://linux.die.net/man/8/ping) has the following to say about the parameter: "If  preload is specified, ping sends that many packets not waiting for reply."

So, can you retry with ping 192.168.1.1 -s 65500? 
If it still fails, can you look at which point/size the package start to disappear?
