What is the status of this bug?
I have the same problem using Debian Wheezy 7.7 32bits. I tried all combinations of “d-i netcfg/wireless” shown in this tread (and some others too) but the preseeded installation always stop at the ESSID selection, with the preseeded ESSID selected (but I still have to press “Enter” to confirm the ESSID the installation to continue).
Any new ideas to fix this? Any feedback is greatly appreciated.
