Yes, I would say so. As far as functionality and fixes are concerned, it
is now actually even better than Qt3 version and I'm more likely to do
future development with the Qt4 version while Qt3 version is mainly
maintained only for backwards compatibility for systems that do not have

I'm now using Qt4 on my Linux system and consequently, the wpa_gui-qt4
version seems more natural one to work with. In addition, I just changed
the Windows binary builds to use the native Qt4 version (they had always
used Qt4 toolchain, but until today, they were using the old wpa_gui
directory with Qt3 support in Qt4).

I don't see these on either Linux (Qt 4.3.2) or Windows (Qt 4.3.3)
builds. Which version of Qt are you using? This is clearly documented to
be Qt3 compatibility signal, but it is somewhat surprising that it is
still working.. Anyway, I'll fix that by changing the activated()
signals to triggered() which seems to be the new name for this QAction

wpa_gui and wpa_cli should behave pretty much same here as far as
network selection is concerned. The only difference would be in the way
wpa_gui automatically updates that combo box and that may sometimes be a
bit confusing..

Based on a quick look through the log, this looks like a potential
driver issue since wpa_supplicant seems to be trying to associate, but
driver does not react to this in any way or well, at least not in a way
that is visible to wpa_supplicant. Which driver are you using?
