Subject: Re: Linksys Routers still Vulnerable to Wps
	vulnerability.

That's definitely not a good thing if it's found to be the case across more
of the vendors.
Is it the intent of the of the column on the google docs spreadsheet (WPS
can be disabled and it stays off), to include confirmation of the retest
after the WPS setting has been disabled?

I wonder if everyone retested after the option was turned off? I hope so.

Thanks
Derek

"Having demonstrated the insecurity of WPS, I went into the Linksys'
administrative interface and turned WPS off. Then, I relaunched Reaver,
figuring that surely setting the router to manual configuration would block
the attacks at the door. But apparently Reaver didn't get the memo, and the
Linksys' WPS interface still responded to its queries—once again coughing
up the password and SSID. "

the testing i did was in early-mid jan, ill verify my findings again. at
work now, but will let you know about config methods.
