Re: cannot capture packets from wifi router(Netgear WNDR3700).

Thanks for replying.
I upgraded from ubuntu 10.10 to ubuntu 11.10. Still no improvement.
My laptop was able to browse to the same website that my phone could, on the local network.
My wireshark version is 1.6.2 from the ubuntu package manager.
I do not know what to do about the NIC driver.

If I do a Web search for

        ubuntu 10.10 "monitor mode"

I find a bunch of people reporting various problems.  Perhaps there are either driver problems with Ubuntu 10.10 or a 
problem with userland code "helpfully" "fixing" connectivity problems due to turning monitor mode on by turning it back 
off.

If I do a Web search for

        ubuntu 10.10 centrino 6200 "monitor mode"

I find

        http://askubuntu.com/questions/45116/my-wireless-card-is-stuck-on-channel-1-when-im-trying-to-use-aireplay-ng

Apparently the problem they had was due to an improperly-patched (probably meaning "unpatched") driver; one poster also 
suggests that network-manager might be acting "helpfully" here.
