Malformed Packets everywhere

0

alt text

I'm not sure what to make of these messages. I've only tested it on wireless connections so far. It doesn't seem to affect my ability to get any where on the internet, but I cannot log in via VPN to work. Wireshark on the work computer shows no evidence of malformed packets, just a constant stream of requests and acknowledgements that go nowhere. Has anyone come across something similar, and how can I fix this?

Thanks, Chris

Can you share a capture in a publicly accessible spot, e.g. CloudShark?

Oddly enough, the [malformed packet] tag doesn't show in the saved capture.

That link takes me to a login page, but I don't have a CloudShark account. You may have to somehow mark that capture as being publicly available even to people without a CloudShark account.

I updated it.

What is the Ethernet preference "Assume packets have FCS" set to? If it's on (checked), what happens if you un-check it?
