Thanks, SD, though unfortunately, plus ça change, plus c'est la même chose.
Both problems are exactly the same as before.
I did however find that I am not alone with "connected to XXXX (unsecured)" balloon messages:
secured but unsecured??? Help - dslreports.com
I'm not going back to WEP security (which didn't exhibit either problem) so I will live with both issues if I have to, but as mentioned earlier if any PPRuNer can recommend a free, or free trial, alternative wireless configuration tool, I'd like to learn about it.
Cheers,
