Hi Al

A fellow New Zealander here, working in Seattle

Check out...

For the most probable reason for seeing Checksum incorrect on your own packets.

HI Guys,

First time posting to this list, and pretty new at using
wireshark. It looks like a great tool.

The reason that I came across WireShark is that I got a new
wireless internet connection. It seems ok, but on streaming
video applications like YouTube and some other things it
seems jerky.

Now this 1800/1800 kbit connection should handle that stuff
with ease.

Anyway a check with wireshark shows that I am getting a lot
of [TCP CHECKSUM INCORRECT] packets. I assume this is bad?

I am the source for all of these packets, and they are on
UDP.

Can anyone please help me understand further what is going
on here?

I would really appreciate it.

Alternatively my msn is bigal_nz@xxxxxxxxxxx if you want to
chat.

Cheers

-Al

PS: I am happy to send a sample file thro, but assume its a
no no for the list?
