I had a play last night with different methods, but got the same result for
all of them. I also fiddled with the config options, but I believe the
wpa_supplicant defaults are quite permissive and the options are more for
restricting the program to certain methods.

My router (A Linksys - I think it's called a "WRT54TG", though I'm not sure)
offers two options that look good - WPA Personal and WPA2 Personal. IT also
offers an Enterprise option for these, but I don't have a RADIUS server so
that seems irrelevant. For WPA Personal I can choose between AES and TKIP;
WPA2 offers "AES" and "AES+TKIP", which I understand actually means "Use AES
if you can, fall back to TKIP if you can't."

Anyway, I tried all four options, but I still got my associated/unassociated
flip-flopping described previously. As I say, my desktop PC can connect
fine, so I'm really not sure where the problem lies - either with the hostap
driver or the wifi card itself, I suppose (my desktop is not prism-based).

So, what now? Is there some more debugging output I can provide to try and
nail down the problem more? Is there an alternative (ndiswrapper?) I can use
that may work and get me using WPA2 with this access point?

Thank you,
