Asus WL-300g in 'client mode'

Hi All,

I hope to have bought (but haven't actually got as yet) a Asus WL-300g
to be used at the 'remote end' to provide access to my wireless
network by a single PC (down the workshop). (the link is currently
running over a pair of Netgear ME102's).

I'm making the change in the hope I can potentially improve the
wireless security by using a long and very random (before anyone says
<g>) WPA-PSK key or possibly even Radius (the ME102's only support
128 bit WEP).

The problem is I have seen differing specs for the WL-300gm some
suggesting they onlt support WEP and others WPA but I understand this
model is firmware compatible with many others I should be able to
flash it with something that will allow me to use it as I need?

Could someone confirm *all* Asus WL-300g's can be flash upgraded
(knowing my luck the one I've bought can't <sigh>) and where I would
find these 'other' firmware options please?

All the best ..

p.s. Sri, I did ask something similar before but I think it got lost
in the thread / noise ... and if I need to buy 2 Asus WL-300g's (to
do what I want to do) I willl need to know the answers to the above
asap. Thanks
