relevant details from customer:
Netgear WG602 v2 using WPA-PSK with TKIP
SSID HomeLAN

In order to get a connection he says he has to:
1) Switch off SB3, and leave it switched off for 20 minutes.
2) Switch it on.
3) Choose to setup a wireless network.
4) Ignore the offered SSID (HomeLAN), and instead choose to key your
own
SSID.
5) Key EXACTLY THE SAME value for the SSID as was previously offered -
in
my case HomeLAN
6) Enter your key. In my case a 12-character key works; a 17-character
key
did not.
7) Cross your fingers whilst it connects. Usually with either 2 or 1
seconds remaining on the countdown. (The SB1 used to connect at 17
seconds
remaining)
8) Cross your fingers again whilst it gets an IP from DHCP. Hopefully
before the countdown finishes, and hopefully not a 169.x address.
9) Check your wireless signal strength. In my case it's always 88% or
above.
10) Listen to your music!
