It’s a setting in preferences for 802.11. 

Some capture software will mute FCS to all zero value. 
Ideally you want FCS captured, and wireshark to be able to validate it.

Hi Anthony,

I am not sure whether my installation is configured to assume FCS.
Since other people do not show those packets as malformed, perhaps I
have that set?
What can I check this/how to turn that off?
Thanks,

Reinoud.

Hello,

Do your captured packets include an FCS?
Is your wireshark installation configured to assume packets have FCS?

Hi Everyone,

Ive got something other people i know are not experiencing.
When I am opening a sniff with wifi traffic, all beacons show up as malformed.
Same with probe responses and lots of other traffic.
When other's I know open that file on their own machine, it shows fine.
I seem to be the only one who's having this problem.
I resintalled wireshark, but to no avail.
Did anyone experience this, is there a setting or anything I can do to
remedy this?
Thanks,

Reinoud.
