View Full Version : WPA-PSK bug on SB2?

A bit of an odd one - i don't know if it's a bug or not. I set up WPA-PSK
on my Netgear router with a 12 digit numerical key. This worked fine on my
XP laptop and on the Nokia 770 but my SB2 will not play ball - it gets as
far as DHPC but takes a bizarre IP address on a completely different subnet
which of course means it can't connect with my server. Adding a single
non-numerical character and it's fine. Is this the SB2 thats out of spec or
are the other devices overly flexible in what they'll allow?

I believe if the whole key is numeric, the SB firmware will assume you're typing in a number instead of a string.

It's more a user interface thing than a bug, and I don't know of any clean way to do it. (Since you may actually -want- to enter a big hex number as your key, is the 'bug' in the SB for letting you? Or is it in your other hardware for insisting it's ASCII?)

I didn't know about the numeric entry thing, but is there a reason why you're using such a weak WPA key? Twelve characters would be trivial to crack.

From what I've read, WPA keys can be from 8 to 63 ascii characters or 64 hexadecimal digits (256 bits). I've tried to enter a 64 hex digit key with and without a 0x on the front but the SB2 ontly allows 63 characters. Is the key entry validation broken?

but some one would still have to want to and i've nothing worth hacking.
There are 4 or 5 other networks around that i can see and i know that some
of them are unsecured. I see it as a deterrrent.
