To try to dig deeper into my network problems with 1.16 I thought I would try ping'ing my router with different sized packets. Before testing 1.16 I did a sanity check with 1.15.12 The largest packet that worked was 1472 bytes. Anything larger and there was no repsonse. I am going to try again with 1.16 but I just wondered if this was normal sort of behaviour for ping ?` Regards, Peter
