To KMadvisor (04/19/2008):
Firstly, you don't say which version of Tiger you have:
Sorry, I already use 10.4.11. Many thanks for your input...
Would be happy with WPA or WPA2, have simply "tried all" in order to get a functioning secure net access...but no success as yet. Please note, I live in HGK as well as BKK, have no trouble in HKG so do know the basics. Having troubles I cannot decipher (yet) in BKK.
"WEP is no longer recommended", yes I no, again, simply trying every/anything :-(
(something to do, I think, with the first handshakes between the laptop and router being broadcast 'in the clear'. Sorry, not that technical, me.

)
"MAC addresses on the router simply act as a admission list." Isn't this a form of security, i.e. if not on the list, can't get in? That's what I meant. I have no trouble setting up the mac addresses, but if I do so, and set up the "unsecured" network, does this unsecured network admit only listed mac addresses? (In my earlier effort, it seemed that the mac addresses were not "active" unless a secured network was set up, with is a loop back to the original problem.) Sorry for confusing in my earlier choice of works - hope this helps.
"...write out on paper *exactly* the password used ..." appreciate the advice, but really, the problem is NOT a factor of a typo
Don't be discouraged; Mac OSX Tiger ought not to be a problem with wifi.
...argh.... not sure if that denotes discouragement or sheer exasperation... I'm trying to convince my partner to switch to mac, and my own conversion is "teaching" him that such a move is not wise...wish it were different!
Best of luck! --- thanks!!
