I'll check out the branch, thanks!
I'm a bit confused about shared key authentication as well, though. My
router basically has a couple of radio buttons on the WEP configuration
page:
Authentication Type: ( ) Open System ( ) Shared Key
WEP: ( ) Disable ( ) Enable
They say the following about it:
"Select your Authentication Type:
* Open System (no authentication or encryption)
* Shared Key
"For easy installation, Open System is the default. However, NETGEAR
strongly recommends that you change to Shared Key. If Shared Key is
selected, you need to enable the WEP and enter at least one shared key."
So I've got Shared Key and Enable, respectively, set.
Is there another scheme that's more secure that my router doesn't support?
(Perhaps they've got a firmware upgrade for it.)
