Re: Unable to join open WEP wireless network

Dear Andy,

Thank you.

Unfortunately the trouble with the open WEP network happened while I
was in a conference earlier today. The conference ended and I no
longer have access to the particular network. I cannot tcydump.

Yes, I had tried without -nwkey. You gave a good tip about "mode 11g".
I will try it out next time when I am facing a similar problem!

Sincerely,
Xianwen
